The penal colony of New South Wales was founded in January, 1788, with a population of convicts, military people, and a few civil officers. The settlement displaced one of the oldest cultures on earth, as English law failed to recognize that the Aborigines had any right to the land they had occupied for 40,000 years. On their first night ashore the women convicts were greeted by mass debauchery that deserved to be recorded by Hogarth, all under a heavy thunderstorm.

The coal seams of the coal basins in New South Wales contain vast resources of methane. The gas has been of interest in the past, principally because the inflow of significant quantities into coal mine workings is a danger to mine safety and reduces production. Drainage techniques have been introduced into deeper collieries but they have not proved to be totally effective.Surface pre-drainage operations using hydraulic fracturing to stimulate gas production have been successful in the United States over recent years. The technique has yet to be successfully tested in New South Wales but if effective it will enable future mining areas to be drained prior to commencement of mining. The technique will also enable commercial production of large quantities of methane from both within and outside the coal mining areas.Seven organisations have commenced or will soon commence the exploration and development of the State's coal seam methane resources. Total planned expenditure over the next two years is over $4 000 000. Other Australian and overseas organisations are actively reviewing investment opportunities.Detailed exploration programs will be required prior to the commencement of operations because of the relative lack of data on the geology and gas resources of the basins. Differences exist between Australian and American coals and comparative reservoir and pilot studies will be required to determine the most effective pre-drainage methods. Potential markets exist in the State for methane and changes have been made to relevant legislation and administrative procedures to create incentives for exploration and production. Careful land-use planning will be required to ensure that the gas resource is not sterilised.

I examine the evolution of conflict and cooperation during economic growth by analyzing civil disputes in New South Wales between 1860 and 1900. Disputes per capita fell over time and the proportion of cases settled before trial increased, but patterns varied across locations and types of disputes. Economic conflicts were likelier to be settled than personal disputes, and the fraction of cases settled was significantly lower in frontier areas and in districts without access to transportation. The results suggest that increased market exchange facilitates the development of informal rules and encourages transactors to find cooperative solutions through private bargaining.

Abstract In the 1830s, the British government commenced a programme of relocating poor labourers to its Australian colony of New South Wales, a practice known as ‘assisted migration’. Though intended to address the colony’s labour shortage, the new arrivals were met with hostility by the colonial elite, who claimed the immigrants were immoral and unsuitable as workers. While migration historians have shown these judgements to be largely unfair, the forces underpinning these perceptions await a thorough interrogation. This article examines colonial public rhetoric about immigration to reveal attitudes shaped by a tangle of overlapping and reinforcing political, economic, and cultural factors. Ultimately, the colonial elite wanted to control who could enter their community, both physically and socially, which became a temporally persistent pattern vital to the settler colonial project.

From 1991 to 1993 a program of soil sampling was undertaken on neighbouring properties, under organic and conventional management, at Ardlethan in southern NSW. The organic farm was long established, as organic management had commenced in 1963. The conventional farm was well managed in typical fashion for the district. Soil sampling took place in the autumns of 1991, 1992, and 1993. Samples were taken to a depth of 150 mm and analysed for a range of nutrients. Soil on the organic farm contained significantly lower concentrations of extractable P and exchangeable Mn, and had higher pH and higher concentrations of exchangeable Na, Ca, and K. There was no statistically significant difference between the farms in the concentrations of total Mg, Na, N, Mn, and K, nor in exchangeable Mg and organic carbon content.

Basal optically stimulated luminescence (OSL) ages of more than 50 000 years in loessic (parna) mantles on the Central Tablelands of New South Wales indicate significant aeolian silt (c. 30 μm mode) deposition commenced well before the onset of the last glacial maximum. Each mantle consists of >1 m of reddish silty clay loam–silty clay with an earthy fabric which sits atop manganese and iron pans and saprolite. Mixing of saprolite-derived material into the pans and also into the silty layer indicates a site history of steady accumulation of aeolian loess and continual pedogenesis. No palaeosols are found. The OSL chronology of both sites, while low resolution, indicates an almost constant mass accumulation rate from 50 000 years ago through the last glacial maximum and into the Holocene. Local factors affecting retention of deposited dust may be responsible for the apparent passivity of the sites.

The Clarence-Moreton Basin covers an area of some 28 000 km2 in north-eastern New South Wales and south-eastern Queensland. The basin is relatively unexplored, with a well density in New South Wales of one per 1600 km2. Since 1980, Endeavour Resources and its co-venturers have pursued an active exploration programme which has resulted in the recognition of significant petroleum potential in the New South Wales portion of the basin.Previous studies indicated that the Upper Triassic to Lower Cretaceous Clarence-Moreton Basin sequence in general, lacked suitable reservoirs and had poor source- rock potential. While exinite rich, oil-prone source rocks were recognised in the Middle Jurassic Walloon Coal Measures, they were considered immature for oil generation. Moreover, during the 1960's the basin acquired a reputation as an area where seismic records were of poor quality.These ideas are now challenged following the results of a new round of exploration which commenced in the New South Wales portion of the basin in 1980. This exploration has involved the acquisition of over 1000 km of multifold seismic data, the reprocessing of some 200 km of existing single fold data, and the drilling of one wildcat well. Over twenty large structural leads have been identified, involving trapping mechanisms ranging from simple drape to antithetic and synthetic fault blocks associated with normal and reverse fault dependent and independent closures.The primary exploration targets in the Clarence- Moreton Basin sequence are Lower Jurassic sediments comprising a thick, porous and permeable sandstone unit in the Bundamba Group, and channel and point-bar sands in the Marburg Formation. Source rocks in these and the underlying Triassic coal measures are gas-prone and lie at maturity levels compatible with gas generation. In contrast, it was established from the results of Shannon 1 that the Walloon Coal Measures are mature for oil generation and this maturity regime is now considered to be applicable to most of the basin in New South Wales.A consideration of reservoir and source rock distribution, together with structural trends across the basin in Petroleum Exploration Licences 258 and 259, has led to the identification of three prospective fairways, two of which involve shallow oil plays. Exploration of these fairways is currently the focus of an ongoing programme of further seismic data acquisition and drilling.

The Eastern Gas Pipeline is an 18-inch diameter pipeline running from Longford in Victoria to Horsley Park in Sydney, New South Wales—a distance of some 795 kms (Fig. 1).While the construction of the pipeline in approximately 12 months is a considerable achievement, it took more than six years to establish the regulatory and market fundamentals to allow construction to commence. The commercialisation of the Eastern Gas Pipeline took place during a period in which the Australian gas industry was subject to much regulatory and market reform. The project provided some impetus for that reform, particularly in NSW.The pipeline was the first interstate gas pipeline to be committed under the National Gas Pipeline Access Code. It also represented the means by which significant quantities of Bass Strait gas could be supplied to the NSW gas market for the first time.This paper discusses the variety of commercial and regulatory issues that needed to be resolved to allow the Eastern Gas Pipeline to become a reality.

Industry and government bodies have recommended augmentation of traditional production and marketing techniques as ways of increasing an industry’s profitability. This article values the amenity of the wine industry, a sensory experience that provides an array of opportunities both culturally to the tourist and economically to many regions across the world. Using the wine industry in the Central West region of New South Wales, Australia, we use input–output analysis to assess the economic impacts of this industry and the amenity hidden within. The industry not only provides jobs and commerce supporting local prosperity but also supplies a mixed production and consumption amenity from an agricultural product that meets the tourist’s leisure desire – an amenity that transcends from its origin in the vineyard to its destination at the table.

In south-eastern Australia, the pelodryadid Litoria aurea Group (sensu Tyler & Davies 1978) comprises three species: Litoria aurea (Lesson, 1829), Litoria raniformis (Keferstein, 1867), and Litoria castanea (Steindachner, 1867). All three species have been subject to declines over recent decades and taxonomic uncertainty persists among populations on the tablelands in New South Wales. We address the systematics of the Group by analysing mitochondrial and nuclear DNA sequences to assess divergence in the Litoria raniformis from across its current range in New South Wales (NSW), Victoria, South Australia (SA) and Tasmania. We also included samples of Litoria castanea from a recently rediscovered population in the southern tablelands of NSW. Our phylogenetic and population genetic analyses show that Litoria raniformis comprises northern and southern lineages, showing deep mitochondrial DNA sequence divergence (7% net average sequence divergence) and can be diagnosed by fixed allelic differences at more than 4,000 SNP loci. Samples of the northern lineage were collected from the Murray-Darling Basin while those of the southern lineage were collected from south-eastern South Australia, southern and south-eastern Victoria and Tasmania. Analysis of the morphology and bioacoustics did not unequivocally delineate the two lineages. The presence of a hybrid backcross individual in western Victoria at the northern margin of the southern lineage, leads us to assign sub-species status to the two lineages, L. r. raniformis for the northern lineage and L. r. major for the southern lineage. Our data do not unequivocally resolve the taxonomic status of L. castanea which will require molecular genetic analyses of museum vouchers from those parts of the range where L. castanea and L. raniformis are no longer extant. Our data also suggest that human mediated movement of frogs may have occurred over the past 50 years. Our genotyping of vouchers collected in the 1970s from the Mount Lofty Ranges in South Australia detected mitochondrial haplotypes of both sub-species and SNP analysis showed that a single Tasmanian specimen was a backcross with L. r. raniformis ancestry. Movement of L. r. raniformis into Tasmania and both sub-species into the Mount Lofty Ranges are not likely due to passive movements of animals through agricultural commerce, but due to the attractiveness of the species as pets and subsequent escapes or releases, potentially of the larval life stage.

This study advocates that websites’ levels of applications/functions are a major determinant of customer satisfaction, and by extension, a determinant of the merit of a firm's e-commerce system. In particular, it aim is to inspect the potential influence of small enterprises website applications on visitor satisfaction. The model fashioned for this research outlines the main constructs involved in manifesting the potential influence of website characteristics on visitor satisfaction. An instrument consists of 17 questions was designed to collect data required to evaluate the actual satisfaction of visitors with small enterprises websites. The model was tested via surveying individuals in urban New South Wales (Australia). The expectation disconfirmation theory (EDT) was employed to assess user satisfaction. The multiple regression method (MLR) technique was applied to analyse the collected data. The results demonstrated that the competence of website components is critical in shaping visitors, customers, and potential customers’ attitudes, behaviours, and satisfaction.

Few studies have examined the link between air cargo and business travel, despite there being a generally accepted understanding that these two variables are inextricably related to each other. This paper examines the relationship between air cargo and business travel at the international level and analyses how these two variables are causally related. Moreover, we break down the sample into three major Australian states (New South Wales, Queensland, and Victoria), as each possesses a distinct flavour in trade and commerce. Utilising Granger causality methods, we have found evidence that there is a direct causal relationship between business travel and air cargo in the short run, and a bi-directional relationship in periods of 12 months and longer. The nature of the Granger causality at the state-level substantially differs from state to state, suggesting that the economic landscape of Australia’s local economy has a significant impact on the air cargo and business travel relationship.

Two species of rock-wallabies occur in New South Wales; the Yellow-footed Rock-wallaby Petrogale xanthopus in the far west and the Brush-tailed Rock-wallaby Petrogale penicillata in the east. Both species have contracted in distribution and abundance across their former range and are threatened in NSW. The P. xanthopus population in NSW now comprises only two sub-populations. Removal of large numbers of goats, thought to be the primary threat, has not halted the wallaby's decline. Fox and cat predation is now considered the major threat. Fox control is currently being conducted. P. penicillata has undergone a dramatic and continuing decline from being common throughout south-eastern Australia to currently being extremely rare in the southern and western parts of its range and found only in isolated colonies throughout the north of its range. Predation (particularly fox, but including dog and cat), once again, is considered the major threat. A recovery program has been commenced involving the media and wider community in locating extant colonies, as well as developing and implementing Population Management Plans. This program has documented further local extinctions and extremely low numbers of individuals in colonies in the southern and western parts of the range. While no surviving colonies are known between the Shoalhaven area and the Victorian border, there remain more and larger colonies in the north of the state.

AbstractThe Richmond River Valley of northern N.S.W. contains a late Pleistocene succession dating back to approximately 250,000 yr B.P. Dinoflagellate and spore-pollen assemblages from the lowest interval, the lower “Dungarubba Clay” of Drury (1982), indicate deposition in a restricted estuarine environment at approximately 250,000 yr. Deposition in the overlying interval, the upper “Dungarubba Clay” and “Gundurimba Clay”, at approximately 120,000 yr B.P., began in a restricted estuary, but rising sea level caused inundation and deposition in a more open, marine-dominated environment. Dinoflagellate cyst assemblages from the last interglaciation (stage 5) are interpreted by analogy with those from the morphologically similar, modern Broken Bay, N.S.W. They are indicative of an open, marine-dominated environment and imply that barrier formation in the Richmond River Valley, and possibly elsewhere in northern N.S.W., did not commence until after the initial postglacial transgression. Synchronous changes in sea level and rainforest development suggest that there was no significant time lag between climate and sea-level change.

This study of attrition compares the prosecution of child sexual offenses reported while the complainant was still a child with those in which the report was delayed into adulthood; it also compares matters involving adult and young (under 18 years) suspects/defendants. It is based on an analysis of police and court administrative data in New South Wales, Australia over a 14-year period (2003–2016). Only one in five (21.6%) proceeded beyond the investigation stage. Criminal proceedings were more likely to commence when the alleged victim was 7–12 years old at the time of the incident, when the suspect was an adult and at least 10 years older than the victim, and also when the report to police was made when the victim was an adult. Just over half (55.5%) of the matters finalized in court resulted in a conviction. Cases in the higher courts were less likely to be dismissed and more likely to feature guilty pleas and convictions at trial than cases in the lower courts. The overall estimate is that only 12% of offenses reported to police resulted in a conviction, at a relatively stable rate over 14 years. These findings are consistent with those of comparable studies.

Management of Acid Soils Through Efficient Rotations (MASTER) is a long-term agronomic experiment commenced in 1992. There were 3 fundamental treatment contrasts in this experiment: (a) annual systems v. perennial systems; (b) limed v. unlimed treatments; and (c) permanent pastures v. pasture–crop rotations. The soil was acidic to depth with pH (in CaCl2) below 4.5 and exchangeable Al above 40% at 0.10–0.20 m when the experiment started. Lime was applied every 6 years to maintain soil pHCa at 5.5 in the 0–0.10 m soil depth. A financial analysis was undertaken to estimate potential benefits and costs involved in liming acid soils on the south-western slopes of New South Wales, based on data from the MASTER experiment. The most important finding from the current study is that liming pastures on soils that have a subsurface acidity problem is profitable over the long-term for productive livestock enterprises. The pay-back period for liming pastures, grazed by Merino wethers, was 14 years for both annual and perennial pastures. More profitable livestock enterprises, such as prime lambs or growing-out steers, were estimated to reduce the pay-back period. This gives farmers confidence to invest in a long-term liming program to manage highly acid soils in the traditional permanent pasture region of the high-rainfall zone (550–800 mm) of south-eastern Australia. Results from the current study also confirmed that the total financial return from liming is greater if the land is suitable for operation of a pasture–crop rotation system. The positive cash flows generated from cropping in a relatively short time can significantly shorten the pay-back period for the investment in lime. But cropping without liming on soils with subsurface acidity was worse than grazing animals. Crop choice is crucial for the perennial pasture–crop rotation. Inclusion of high-value cash crops, such as canola or a wheat variety with high protein, would lead to a rise in the aggregate benefits over time as the soil fertility improved and soil acidity was gradually ameliorated.

Objective: Ongoing transmission of tuberculosis (TB) continues in Indigenous communities in New South Wales (NSW), Australia. In a pilot project, a Public Health Unit TB team partnered with an Aboriginal Community Controlled Health Service (ACCHS) in a community with a cluster of TB to augment screening for latent TB infection (LTBI) using interferongamma release assay (IGRA). This study examined screening data and programme outcomes at 12 months post hoc to advise practice and policy formulation. Methods: We conducted a retrospective, cross-sectional analysis of demographic and clinical data of ACCHS patients, stratified by IGRA testing status. Differences in sex and age distribution between the groups and cases of a genetically and epidemiologically linked TB cluster in Aboriginal people in NSW were assessed using non-parametric tests. Results: Of 2019 Aboriginal and Torres Strait Islander people seen by general practitioners during the study period, 135 (6.7%) participated in the screening. Twenty-four (17.8%) participants were IGRA positive. One person was diagnosed with active TB. Twelve participants received a chest X-ray at the time of the positive test, and six participants had an additional chest X-ray within 12 months. None commenced preventive treatment for LTBI. Discussion: ACCHS screening for LTBI reached individuals in the age group most commonly affected by TB in these Aboriginal communities. No conclusions can be made regarding the population prevalence due to the low screening rate. Further strategies need to be developed to increase appropriate follow-up and preventive treatment.

Rising groundwater, and the potential for development of shallow watertables, were recognised in the Lower Macquarie Valley of New South Wales in the late 1980s. Irrigated agriculture was proposed as a possible source of the recharge causing the problem. This paper reports the increase in deep percolation rates resulting from cotton irrigation on 4 soils in the Lower Macquarie Valley, New South Wales. Changes in deep percolation rates were measured on these soils over the long-term, using temporally separated chloride profiles and mass balance modelling. These changes in long-term deep percolation rates were integrated over all years since irrigation commenced. Irrigation affected deep percolation on all soils, with an increase in long-term mean rates ranging from 17 to 202 mm/year. This equated to increased leaching rates ranging from 3 to 25%. Deep percolation appeared to be related to the clay content of the B horizon. The potential groundwater rise varied from 37 to 524 mm/year. The largest increases in deep percolation rates corresponded to sites where the watertable was closest to the soil surface. This suggests that the development of shallow watertables is related to recharge resulting from irrigated agriculture. Detailed studies of deep percolation under irrigated agriculture are required in the Macquarie Valley.

Summary. The use of nitrogen fertilisers to arrest the decline in soil nitrogen fertility in the northern grains belt of New South Wales has been the subject of many years of research, however, little is known about how farmers make decisions about nitrogen fertiliser. A survey of 400 wheat farmers in northern New South Wales in April 1997 revealed that many have recently changed their fertiliser practices. Although most respondents had been growing wheat since the 1960s, regular applications of nitrogen only commenced in the mid 1980s. Initially only low rates of nitrogen were applied, but in the last 2–5 years, the nitrogen rates have substantially increased. These changes are notable because until this decade, most were content to rely mainly on mineralisation of soil organic nitrogen, whereas, now, half the respondents in the survey plan to add as much nitrogen in fertiliser in 1 year as was removed in the previous year’s wheat crop. Farmers were asked to rate the importance of a number of factors that have been promoted as means of tactically adjusting fertiliser rates. This study found a disparity between the level of measurement and precision suggested by the majority of research, development and extension programs compared with the methods used by farmers. In general, the respondents to the survey have rejected, or are yet to adopt, regular soil testing, the use of climate forecasts and decision support programs. Rather, they rely on simple rules of thumb based on readily accessible data such as past grain protein content and cropping history.

Few can have failed to notice the interest in both the dental and the lay press in the first orthodontic therapy course run under the auspices of the Faculty of Dental Surgery (FDS). All of the trainees on the Yorkshire course seem to have been in print at some stage (and some on several occasions) and it is evident that all seem to be relishing their new role and the challenges it brings. A second intake is planned for July 2008. The Yorkshire course is now to be joined by a second course based in South Wales, which will take 12 trainees and will commence in the summer of 2008.

Quarterly spotlight counts of rabbits were conducted at three sites in central-western New South Wales. These counts commenced two years before the arrival of rabbit haemorrhagic disease (RHD) in the winter of 1996. The existing data on quarterly rates of change in rabbit abundance for the three populations provided a unique opportunity to study the effects of RHD on rabbit demography. Prior to the arrival of RHD, all three populations underwent phases of sequential increase and decrease in each year. On the basis of these patterns, RHD had a variable influence on the demography of the three rabbit populations. In 1996–97, the density of two populations declined over an expected period of increase, while at the third site the density increased as expected from pre-RHD patterns. Twelve months after their failure to generate expected positive rates of increase the two affected populations had returned to the normal sequence of increases and decreases in density although still at comparatively low numbers.

The study area is within PEP 11, which is more than 200 km in length, covers an area over 8,200 km2 and lies immediately offshore of Sydney, Australia’s largest gas and petroleum market on the east coast of New South Wales. Permit water depths range from 40 m to 200 m. While the onshore Sydney Basin has received episodic interest in petroleum exploration drilling, no deep exploration wells have been drilled offshore.A reappraisal of available data indicates the presence of suitable oil- and wet gas-prone source rocks of the Late Permian coal measure succession and gas-prone source rocks of the middle to early Permian marine outer shelf mudstone successions within PEP 11. Reservoir quality is an issue within the onshore Permian succession and, while adequate reservoir quality exists in the lower Triassic succession, this interval is inferred to be absent over much of PEP 11. Quartz-rich arenites of the Late Permian basal Sydney Subgroup are inferred to be present in the western part of PEP 11 and these may form suitable reservoirs. Seismic mapping indicates the presence of suitable structures for hydrocarbon accumulation within the Permian succession of PEP 11, but evidence points to significant structuring post-dating peak hydrocarbon generation. Uplift and erosion of the order of 4 km (based on onshore vitrinite reflectance studies and offshore seismic truncation geometries) is inferred to have taken place over the NE portion of the study area within PEP 11. Published burial history modelling indicates hydrocarbon generation from the Late Permian coal measures commenced by or before the mid-Triassic and terminated during a mid-Cretaceous compressional uplift prior to the opening of the Tasman Sea.Structural plays identified in the western and southwestern portion of PEP 11 are well positioned to contain Late Permian clean, quartz-rich, fluvial to nearshore marine reservoir facies of the coal measures. These were sourced from the western Tasman Fold Belt. The reservoir facies are also well positioned to receive hydrocarbons expelled from adjacent coal and carbonaceous mudstone source rock facies, but must rely on early trap integrity or re-migrated hydrocarbons and, being relatively shallow, have a risk of biodegradation. Structural closures along the main offshore uplift appear to have been stripped of the Late Permian coal measure succession and must rely on mid-Permian to Early Permian petroleum systems for hydrocarbon generation and accumulation.

Introduction: Earlier access to lung cancer specialist (LCS) care improves survival. We examined times to diagnosis and treatment of patients with lung cancer in rural and metropolitan New South Wales (NSW) Australia, benchmarked against recent timeframe recommendations. Materials and Methods: Semistructured interviews of recently diagnosed patients with lung cancer from five NSW cancer centers were used to determine standardized time intervals to diagnosis and treatment, triangulated with Medicare data linkage and medical records. We used descriptive statistics to evaluate the primary end points of median time intervals from general practitioner (GP) referral to first LCS visit (GP-LCS interval) and to treatment start (Secondary Care interval). Univariable and multivariable analyses were used to study associations with delays in end points. Post hoc survival analyses were performed. Results: Data linkage was performed for 125 patients (68% stage IV; 69% metropolitan), with 108 interviewed. The median GP-LCS interval was 4 days, with 83% of patients seeing an LCS within the recommended 14 days. The median Secondary Care interval was 42 days (52% within 42 days). There were no significant differences between time intervals faced by rural and metropolitan patients overall, although metropolitan patients took 18 days less than rural counterparts to commence radiation/chemoradiation (95% CI, −33.2 to −2.54; P = .02). One third of patients perceived delays. Delays did not affect survival. Conclusion: Rural and metropolitan NSW patients face comparable time lines to diagnosis and treatment of lung cancer. Most patients are seen by an LCS within recommended timeframes, but transition through Secondary Care and addressing patient expectations could be improved.

Four experiments were commenced after a 1980 wheat crop, and a fifth after the 1981 crop, at different sites representing the major soil types of northern New South Wales in the 550-700 mm rainfall zone, to examine the influence of 3 fallow management practices [no tillage (NT); stubble retention after harvest, cultivation (SM); stubble burning after harvest, cultivation (SB)] on wheat production. Data considered in this paper cover the continuous wheat subtreatments of the 5 experiments (1981-90). Nitrogen applied at 50 kg Nlha in addition to the basal treatment was included as a treatment from 1986 to 1988. Across all sites and seasons, grain yields were in the order SB>SM = NT, stubble retention having a greater effect than tillage. In some years at some sites, differences in grain yield and grain N yield were not significant. In others, when significant yield differences occurred, variations in grain yield and grain N yield were highly correlated with differences in soil N available for the crop. The data show that the influence of fallow management interacted with season and crop nutrition, and required long-term study for proper assessment.

In Australia, all newborns born in New South Wales (NSW) and the Australia Capital Territory (ACT) have been offered screening for rare congenital conditions through the NSW Newborn Screening Programme since 1964. Following the development of the Australian Newborn Bloodspot Screening National Policy Framework, screening for congenital adrenal hyperplasia (CAH) was included in May 2018. As part of the assessment for addition of CAH, the national working group recommended a two-tier screening protocol determining 17α-hydroxyprogesterone (17OHP) concentration by immunoassay followed by steroid profile. A total of 202,960 newborns were screened from the 1 May 2018 to the 30 April 2020. A threshold level of 17OHP from first tier immunoassay over 22 nmol/L and/or top 2% of the daily assay was further tested using liquid chromatography tandem mass spectrometry (LC-MS/MS) steroid profiling for 17OHP (MS17OHP), androstenedione (A4) and cortisol. Samples with a ratio of (MS17OHP + A4)/cortisol > 2 and MS17OHP > 200 nmol/L were considered as presumptive positive. These newborns were referred for clinical review with a request for diagnostic testing and a confirmatory repeat dried blood spot (DBS). There were 10 newborns diagnosed with CAH, (9 newborns with salt wasting CAH). So far, no known false negatives have been notified, and the protocol has a sensitivity of 100%, specificity of 99.9% and a positive predictive value of 71.4%. All confirmed cases commenced treatment by day 11, with none reported as having an adrenal crisis by the start of treatment.

IntroductionIn Australia, New South Wales (NSW), abortion has recently been removed from the criminal code. Previous research from Australia and other high-income countries has focused on adult women’s access to abortion services. This protocol describes a five-stage mixed-methods study to determine the care trajectories and experiences of adolescent females, aged 16–19 years, seeking an early induced abortion in NSW. The aims are to (1) explore the needs and perspectives of adolescent females seeking sexual and reproductive health services in NSW and (2) develop a framework for abortion service provision for adolescents in NSW.Methods and analysisThis study comprises: (1) semistructured qualitative interviews with key informants, individuals with diverse, in-depth experience of providing and/or supporting abortion care in NSW; (2) a cross-sectional online survey of adolescent females residing in NSW; (3) case study interviews with adolescents females who have accessed an abortion service in NSW; (4) a co-design workshop with adolescents who took part in stage 3 to develop relevant knowledge and recommendations and (5) a knowledge dissemination forum with key stakeholders.Ethics and disseminationEthics approval has been received from the University of Technology Sydney Human Research Ethics Committee for this study. Data collection commenced in March 2019 and will continue until the end of 2020. This study aims to develop a deep understanding of adolescent abortion care trajectories and experiences of abortion services in NSW. The study will deliver co-produced recommendations to improve adolescent access to abortion information and services.

There is increasing concern about the global decline of amphibians and reptiles. One problem with documenting declines and identifying underlying causes is the absence of historical data to compare to current data. Here we provide historic data for Kioloa on the south-eastern coast of New South Wales. In this region considerable clearing of natural forest and woodland and creation of farmland ponds took place during the second half of the 20th century. The Australian National University has a field station at Kioloa and R.E. Barwick introduced us to the field station and what was known of the herpetofauna in the mid-1980s. We undertook detailed observational surveys of the herpetofauna at this time and we revisited the area at other times, focusing on the coastal habitats. We found 13 species of frogs and 11 species of reptiles. Three further frog species and one reptile species known to occur in the area in the 1980s were not detected by us. More recently, one further frog species and six reptile species were added to the list, raising the total to 17 frog and 18 reptile species. The number and composition was similar to other locations of coastal New South Wales, except for some of the rarely encountered species. No strictly forest-dependent species were observed in the partially cleared survey area and such species presumably had already disappeared from these areas already before we commenced our observations. The frog Pseudophryne bibronii was still common in tall open-forest but was uncommon in partially cleared areas. Six species of frogs and one species of reptile presumably benefited from the anthropogenic habitat modifications. No declines of common species of reptiles occurred between the mid-1980s and 1993 but all species of frogs were very rare in 1993 due to very dry conditions. Litoria aurea, a threatened species of frog that was widespread in the mid-1980s, survives (2012) only at one site in the area.

Studies were conducted at 3 pasture sites in northern New South Wales to examine the effects of grazing treatments over 4 years (spring 1997 to spring 2001) on soil microbial biomass carbon (C), labile C, total C, and total nitrogen (N). These data were collected (0–0.05 m soil depth) at 9 sampling times in 2 replicates of 5 (native pastures) or 4 (a sown pasture) grazing treatments and examined for differences over time using cubic spline analyses. For each site, differences among grazing treatments were also examined in spring 2001 for herbage, litter, and root mass (kg DM/ha), ground cover (%), and perennial grass basal cover (%). Indices were also calculated for the C pool index (CPI), lability index (LI), a carbon management index (CMI), and the microbial quotient. Relationships among microbial biomass C, labile C, total organic C, CPI, LI, CMI, microbial quotient, herbage mass, litter mass, and ground cover were examined by linear regression and correlation analyses. For each of the sites, treatment differences in the linear trend over time for soil microbial biomass C, labile C, total organic C, or total N were not significantly different (P > 0.05). In spring 2001, (4 years after treatments commenced) there were also no significant effects of treatments within sites on soil total organic C and none of the indices (lability of C, CPI, LI, CMI, or the microbial quotient) indicated any distinct trends among treatments. However, in spring 2001, there were significant (P < 0.05) treatment effects at both native pasture sites for herbage mass, litter mass, and ground cover. Similarly, in autumn 2001, herbage mass, root mass, and perennial grass basal cover were lowest (P < 0.05) in the continuously grazed high-stocking rate treatment at the sown pasture site. For all data, microbial biomass C was 10.35% of labile C and labile C was 21.60% of total C. From autumn 1998 to spring 2001, labile C was positively correlated (P < 0.05) with total C (r = 0.72) and in spring 2001, these 2 variables were also highly correlated (r = 0.98).

The effects of defoliation intensity and drought severity on levels of water-soluble carbohydrate (WSC), fructan, and etiolated regrowth of 6 important perennial grasses were investigated. The experiment was conducted under a rain-out shelter at Armidale, NSW, Australia, using 6 perennial grass species (Phalaris aquatica cv. Sirosa, Festuca arundinacea cv. Demeter, Dactylis glomerata cv. Porto, Lolium perenne cv. Victorian, Microlaena stipoides cv. Shannon, and Austrodanthonia richardsonii cv. Taranna) subjected to 3 moisture regimes (non-stress moisture, and moderate and severe drought) and 2 defoliation intensities (moderate and severe) over 2 seasonal sequences (spring–summer and summer–autumn).The range in WSC, fructan, and etiolated regrowth of the species varied, with Festuca and Lolium having the highest WSC and fructan concentrations. Austrodanthonia had the lowest WSC concentration of the species. Unlike the introduced species, the natives did not store fructans. The species varied in their response to the treatments imposed. Festuca and Phalaris had the highest etiolated regrowth and showed the greatest effect of defoliation intensity. Etiolated regrowth appeared to be a sensitive measure of plant status, showing the fragile nature of some of the species.The effect of defoliation intensity and drought varied with season. Defoliation intensity had little effect on carbohydrate reserves of all species, except Festuca, during summer of the spring–summer experimental season. During the summer–autumn experimental season, severe defoliation reduced the rate of accumulation during the period December–April. Drought affected carbohydrate accumulation and utilisation. Carbohydrates that had been accumulated at the end of spring of the spring–summer experimental season in plants affected by drought were utilised during summer. However, if drought commenced in summer, carbohydrate accumulation continued for 120 days in all species studied, and 180 days in Lolium and Phalaris.Autumn appeared to be a period when plant reserves were particularly susceptible to stress. The importance of WSC, fructans, and etiolated regrowth as measures of plant reserves, and their role in persistence were discussed.

Under the Distance Education Plan of the NSW Department of School Education, the provision of a full secondary education to rural students has been enhanced through the use of technology based communication networks. In the Riverina region of New South Wales, a pilot project linking three Central Schools into a cluster commenced in 1990. This pilot project is known as the Telematics Access Program and is similar to other projects in operation in Victoria and Queensland. Each school is linked to the other schools in the cluster by teleconference, fax and electronic blackboard computer facilities. Through the schools in the cluster sharing teacher expertise and using the technology to link students and teachers, a comprehensive Years 11 and 12 curriculum has been offered to these students. Students can select from 17 subjects currently available.

Population declines and range contractions among Australian frogs that commenced in the early 1980s continue in some species that were once widespread. The generality of this pattern has been difficult to discern, especially for those species that are encountered rarely because they have restricted periods of calling activity with poorly defined habitat preferences, and are not common. Several lines of evidence indicate that Litoria littlejohni is such a species. This frog was once known from mid-eastern New South Wales to eastern Victoria, and evidence from wildlife atlas databases and targeted searches indicate that it has declined in large portions of its former range, leaving several populations that are isolated, in some cases restricted in distribution, and of small size. We investigated the relationships among populations using mitochondrial ND4 nucleotide sequences and single nucleotide polymorphisms (SNPs) from the nuclear genome. We found that northern and southern populations form two highly divergent genetic groups whose distributions abut at the southern margin of the Sydney Basin Bioregion and these genetic groups also show divergence in morphology and male advertisement calls. Here we describe the populations to the south of the Sydney Basin Bioregion as a new species and provide information on its distribution and ecology. In light of the apparent isolation and small size of known populations of the new species and the consequent restriction of the range of L. littlejohni, we assessed the conservation status of both species.

This paper describes the vegetation of Port Stephens Shire and environs at the time of European settlement, defines the sequence of vegetation clearance since that time, and estimates the extent to which the pre-European vegetation represented Koala habitat. A study of historical records, newspapers, documents and reports was undertaken in conjunction with interviews with long-standing Port Stephens residents. The historical records show that Koalas were widespread and common during early settlement. Reconstruction of the original vegetation was based on descriptions by early explorers and settlers from the early 1800s, when settlement commenced. Most of the land on either side of the Hunter River was vegetated by Shrubby Tall Open Forest intermingling with either Open Swamp Forest, or VineFern Closed Forest, or cedar brush. The first area to be settled was the alluvial land on the banks of the rivers where the soil was fertile and well watered. Settlement proceeded rapidly in the western part of the Shire from the early 1800s, concentrating on the Lower Hunter and Williams Rivers, but not progressing to the east until much later (mid to late 1800s). The historical record was sufficiently detailed to allow reconstruction of Koala habitat distribution at the time of settlement. Ecological history is now emerging as a discipline that has far more than curiosity value. It can provide the essential framework for conserving and restoring those landscapes exploited in the first century of European settlement.

Habitat loss and habitat fragmentation can have major effects on the distribution and abundance of species (Saunders et al. 1987), often in unpredictable ways (Klein 1989; Tilman et al. 1994; Lacy and Lindenmayer 1995; Cunningham and Moritz 1998). An understanding of responses of species, which lead to persistence or extinction in such disturbed systems, is important for the effective management of many taxa in fragmented multi-use landscapes. One way to examine population dynamics in fragmented systems is to analyse the genetic characteristics of subpopulations in remnant habitat patches (Sarre 1995), borrowing from the population genetics literature for the interpretation of key effects. For example, it is well established that a small, completely isolated population will lose genetic variation rapidly due to genetic drift (Lacy 1987). However, loss of genetic variation within, and increasing differentiation between, subpopulations will be counteracted by inter-population dispersal. Theoretical models of metapopulation structure which describe connectivity and stability can be examined using various demographic input parameters. Importantly, such models can also produce predictions for genetic structuring, making the combined use of modelling and empirical genetic data an extremely powerful tool in examining the effects of habitat fragmentation. On this basis, we have recently commenced a series of integrated demographic and genetic studies of the Greater Glider Petauroides volans at Tumut in southern New South Wales. The study area near Tumut in southeastern New South Wales is characterized by an array of remnant patches of eucalypt forest (0.2?125 ha in size) that were created 15?65 years ago by the establishment of an extensive (50 000 ha) plantation of exotic softwood, Radiata Pine Pinus radiata and known as the Buccleuch State Forest (Routley and Routley 1975). Large areas of continuous native eucalypt forest occur at the boundaries of the plantation (Fig. 1), including those within the Brindabella and Kosciuszko National Parks, and the Bondo and Bungongo State Forests.

IntroductionChronic conditions impact indigenous peoples of Australia at a much higher rate than non-indigenous Australians. Attendance at the Medicare Benefits Scheme (MBS) supported indigenous health checks are crucial to improve prevention and management of chronic health conditions. However, in conjunction with lifestyle and environmental factors, attendance rates at primary healthcare services for screening and treatment have fallen in Australia during the COVID-19 pandemic. This study aims to explore the influence of the COVID-19 pandemic on preventive health behaviours of indigenous Australians and the associated barriers to, and enablers of, engagement with health services to formulate a targeted intervention strategy.Methods and analysisA concurrent mixed-methods study (comprising quantitative and qualitative data collection methods) will be employed. Descriptive analysis of MBS data about the characteristics of indigenous peoples of Australia claiming health assessment services will be performed. Generalised estimating equation regression models will be used to examine the use of health assessment services over time. Qualitative interviews informed by indigenous research methods will be conducted. Interviews will investigate barriers to, and enablers of, engagement with health services. Thematic approach guided by the principles of indigenist praxis, storytelling and collaborative research will be used to analyse the interview data. The project commenced in July 2020 and will be completed by July 2022.Ethics and disseminationThe project received ethics approval from the Aboriginal Health and Medical Research Council of New South Wales and the University of New England Human Research Ethics Committee. Findings will be disseminated via peer-reviewed journal articles, conferences, government and relevant stakeholder reports, and infographics.

Female reproductive success and the recruitment of offspring to the next generation are key components of animal population dynamics. With an annual commercial harvest of between 13 and 22% of the red kangaroo (Macropus rufus) population, it is increasingly important that these processes are understood. We used data on the reproductive success of 33 free-ranging female M. rufus on Fowlers Gap station in far western New South Wales to determine the expected lifetime reproductive success (LRS) of females within an unharvested population. We also designed a model to generate predictions about female LRS incorporating empirical relationships between a mother?s reproductive success and maternal age, environmental conditions and the sex and survivorship of a previous reproductive attempt. Results from observations on female LRS (calculated from annual weaning rates) and those generated by the model predict that female M. rufus on ?Fowlers Gap? wean, on average, 3.7 young in a lifetime (ranges 0 - 11 and 0 - 20, respectively); representing only 41% of their maximum reproductive potential. Manipulation of initial starting conditions allowed the effect of varying environmental conditions on female LRS to be explored. The condition of the environment when females commence breeding does not appear to significantly affect their overall lifetime reproductive output. However, the occurrence of drought does. Females experiencing two droughts in a lifetime did not live as long and weaned fewer offspring and grandoffspring (from their daughters) than those females experiencing only one drought in a lifetime. In addition to the adverse effect of drought on the reproductive success of female M. rufus in this study, we suggest that, given the relatively high and stable population densities of M. rufus on ?Fowlers Gap?, other mechanisms (acting primarily on juvenile survival) must exist which limit population growth.

Keynote paper presented at the International Leucaena Conference, 1‒3 November 2018, Brisbane, Queensland, Australia.A research program to develop sterile leucaena has commenced to enhance red-meat production in additional regions of Australia including Western Australia, Northern Territory and New South Wales, where growing seeded leucaena is not currently permitted or encouraged. In this study we report on the development of methodology using a mutagenizing agent, EMS (ethyl methanesulfonate), to cause mutations in the self-fertile commercial leucaena cultivar, Redlands. Several experiments to determine the optimum rate of EMS have been completed and first generation mutagenized plants (M0) established in the field at Redlands Research Station, Cleveland, Queensland, Australia. An EMS concentration of 0.35% applied to germination paper proved the best method to achieve a target emergence percentage of 50%. To date, 27 of 179 mutagenized M0 seedless plants are considered to be putatively sterile. A further 1,200 M0 plants have been established in the field providing an even greater chance of identifying sterile leucaena plants with the desired forage quality and psyllid-resistance attributes.

‘Managing Acid Soils Through Efficient Rotations (MASTER)’ is a long-term pasture–crop rotation experiment commenced in 1992. One of the objectives was to demonstrate the extent of crop, pasture, and animal responses to lime on a typical acidic soil in the 500–800 mm rainfall zone in south-eastern Australia. Two types of pastures (perennial v. annual pastures) with or without lime application were established in 1992. This paper presents the results of the pasture dry matter (DM) responses to lime application over 6 years from 1992 to 1997. Results showed that both perennial and annual pastures responded positively to lime on a highly acidic soil on the south-west slopes of New South Wales. Averaged across pasture types and 5 growing seasons, the limed pastures produced 18% more pasture DM (520 kg/ha, P < 0.05) than the unlimed pastures. Significant responses to lime were detected on perennial pastures (610 kg DM/ha, P < 0.05), but not on annual pastures, although the limed annual pastures produced more DM (420 kg/ha, P = 0.20) than the unlimed annual pastures. There was a large seasonal variation in pasture growth rate with the significant lime responses in winter and spring on both perennial pastures (P < 0.05) and annual pastures (P < 0.10 in winter and P < 0.05 in spring), but no responses in autumn and summer on either perennial or annual pastures. The extra growth in winter is of importance as winter is the period when feed is normally inadequate and limits stocking rates. It is recommended that perennial-based pastures should be promoted for the purposes of productivity, in terms of increasing pasture production and improving feed quality, and for the environmental benefits in terms of alleviating the soil acidity problem and reducing the risk of dryland salinity in the high-rainfall zone in south-eastern Australia.

In 2009, 95 farmers in the mixed farming zone of southern New South Wales (NSW), average annual rainfall 450–700 mm, were surveyed about their use of perennial pasture species. Survey responses indicated that, on average, 52% of land was under crop, 29% contained perennial pasture and 19% annual pastures. The proportion of land sown to perennial pastures and the species used differed with rainfall. Farmers identified concerns about the cost of establishment and poor survival of perennial pasture species as constraints to wider adoption. The survey also revealed that cover-cropping (sowing pasture species under the final grain crop in a cropping phase) was the dominant method of pasture establishment. Large-scale, on-farm participatory experiments were sown with the farm machinery, three at Ariah Park and one at Brocklesby in southern NSW in 2009 (annual rainfall 100 mm less than long-term average), and a further two experiments (one at each location) commenced in 2010 (annual rainfall >200 mm above average). These experiments compared the effect of cereal cover-crop sowing rate (standard rates used by the collaborating farmer and half of the standard rate) on the establishment of the perennials lucerne (Medicago sativa), phalaris (Phalaris aquatica), cocksfoot (Dactylis glomerata), and chicory (Cichorium intybus) sown in different mixes and rates with various annual legume species. The persistence and productivity of individual species were monitored for 2 years after sowing. Results indicated little or no effect of the presence of a cover-crop on the initial establishment of any of the perennials, but pasture species survival were severely affected by cover-crop sowing rates as low as half of the farmer practice (10 kg barley or 12 kg wheat ha–1) in 2009. Despite higher than average annual rainfall in 2010 and 2011, the residual effect of establishing pastures under a cover-crop in 2009 was poorer persistence and lower productivity by lucerne at the standard cover-cropping rate, and by phalaris, cocksfoot and chicory at all cover-crop rates, and an increased incidence of weeds. Similar responses to cover-cropping occurred between 2010 and 2012, even with the wetter establishment conditions in 2010, for phalaris, chicory and weeds, despite demonstration at Ariah Park that higher populations of individual perennial species could be achieved by doubling the sowing rate of pasture seed in 2010. Lucerne compensated for lower plant numbers by increasing herbage growth in response to rainfall, but phalaris could not and total pasture productivity over the first 2 years after establishment was greatly reduced by the use of cover-crops in both 2009 and 2010. Cover-cropping also reduced annual legume seedset, which could have implications for future pasture performance. Lucerne was the most consistently productive perennial pasture species evaluated regardless of establishment technique or climatic conditions.

This paper describes the restoration of woody vegetation on my family’s grazing property, ‘Eastlake’ (1202 ha) on the Northern Tablelands of New South Wales. We commenced revegetating ‘Eastlake’ in 1981 to reverse the loss of native tree cover due to New England dieback and improve shelter for livestock and pastures to increase farm profitability. We treated the revegetation program as a long-term business investment and, apart from a 5-year period of overseas employment, have allocated annual funding in the farm business plan ever since. Our decision was based on the benefits of shelter to livestock and pasture production. Once we began revegetation, aesthetics, amenity and the positive impact on the capital value of the farm became important motivations. More recently, increasing the farm’s biodiversity and resilience, and conserving native flora and fauna, have also motivated us. Our strategy is to link upland areas of remnant timber with ridgeline corridors of planted vegetation to maximise shelter, minimise pasture production losses and provide dispersal corridors for fauna and wildlife habitat. Initially, we planted introduced species of tree and shrub, but now we revegetate mainly with native species, as well as fencing off remnant timber to encourage natural regeneration and direct seeding understorey species (mainly acacias) in degraded remnants and elsewhere. Our target is to increase the area of fenced-off and planted timber cover from 8% to 10% over the next few years, which will take the proportion of total effective timber cover from ~8% in 1980 to 18% of the property. The key lessons are to: (1) plan, prepare, plant the right tree or shrub in the right place for the right purpose, and post-planting care (the ‘4 Ps’); (2) integrate revegetation into the whole-farm business plan; (3) finance the work slowly over time with the aid of a spatial farm plan; and (4) adapt to changing circumstances, values and understanding. Research is required to help farmers understand the role of on-farm biodiversity in contributing to the health of the farm business, owner–managers and their families and the farm environment, as well as to regional economies, communities, landscapes and society more generally.

"Growth is impeded by gastrointestinal nematodes in weaned rather than suckling meat-breed lambs in a high summer rainfall region, on the Northern Tablelands, New South Wales."

The hypothesis tested in this experiment was that the effects of gastrointestinal nematodes (GIN) on growth of meat-breed lambs would be absent during the suckling period and greatest after weaning. The experiment was a single factor design conducted on five farms over 2012–2014, using meat-breed lambs (Poll Dorset × Border Leicester/Merino), which were either GIN-suppressed (SUP) or not (NSUP). The experiment commenced at lamb marking and continued for 5 months. SUP lambs were serially treated with short- and long-acting anthelmintics. NSUP lambs were not treated before weaning and at weaning received a short-acting multi-active drench with subsequent treatments varying between farms. Worm egg count (WEC) of NSUP lambs were significantly higher (P < 0.0001) than SUP lambs at weaning (1170 and 10 epg) and thereafter (P < 0.0001) reaching 920 epg 2 months after weaning. Haemonchus contortus was the predominant species present in NSUP lambs with smaller contributions from Trichostrongylus spp. There was no effect of GIN control on lamb growth during the pre-weaning period (SUP 17.2 kg vs NSUP 17.0 kg, P = 0.093), whereas GIN reduced growth of lambs by 0.5 kg (SUP 7.1 kg vs NSUP 6.6 kg, P = 0.002) in the last month of observation. There was no effect of GIN control on lamb mortality. GIN did not affect growth of suckling meat-breed lambs despite high WEC at weaning indicating resilience to GIN infection in lambs growing at 200 g/day. In contrast, post-weaning growth was reduced by GIN infection, despite effective treatment at weaning and movement to GIN ‘safe’ pastures. The susceptibility of weaned lambs to the effects of GIN infection highlights the importance of effective control measures at this time.

Charles Sturt University commenced herbicide resistance monitoring in 1991. A random survey in 1991 to determine the level of resistance in annual ryegrass (Lolium rigidum) to selective herbicides across the south-west slopes region of New South Wales found that 30% of samples were resistant to at least 1 herbicide. A subsequent survey of commercially available ryegrass seed found that 58% of these samples were resistant to at least 1 herbicide. As a result of these findings, a commercial testing service was established and has since received samples from a large proportion of the southern Australian cropping belt. Seventy-seven percent of samples tested were resistant to Group AI, 40% to Group B and 22% to Group AII herbicides. Lower levels of resistance were found to Group D (8%), Group C (1%) and Group M (0.4%) herbicides. The correlation between resistance in Group AI and AII herbicides was lower than expected given that these herbicides are considered to have the same mode of action. Within the Group AI herbicides the observed response of the samples was consistent across herbicide formulations. Resistance to clethodim varied from observed responses to other Group AII herbicides. The variation in resistance levels (and degree of multiple resistance) in each Australian state is discussed in relation to environmental conditions and cultural practices. The size of this dataset allows for the analysis of the relationships present among herbicide resistant annual ryegrass.

In 1996, guidelines were produced for capture and radio-tracking protocols for koala (Phascolarctos cinereus) research within New South Wales (NSW). An integrated project commenced in 1998 to examine P. cinereus ecology and health status in Pine Creek State Forest. This project utilised intensive clinical and pathological assessment protocols on captured P. cinereus in combination with radio-tracking and ecological investigations. The methods used in this project were referred to the NSW Koala Research Committee (KRC) for review in mid 1999 due to the political profile of the study area. The KRC assessed the project protocols and reviewed the original guidelines incorporating some of the protocols used in the Pine Creek project. The outcome is a new set of protocols for P. cinereus research within NSW which are more explicit and restrictive than those applied to P. cinereus research elsewhere or to research on other species. In their current form the new guidelines require a substantial investment in time, equipment, personnel and finance; factors that may deter or restrict future, comprehensive ecological research on P. cinereus populations. They inadequately provide for some practices we believe important in minimising the invasiveness of P. cinereus capture. We propose amendments to the guidelines in the areas of personnel required, behavioural assessment, capture methods, processing safety and tracking frequency. We suggest that these amendments will render the guidelines more accessible to a broader range of projects, and easier to apply under field conditions while preserving the intent to maintain P. cinereus welfare and research best practice.

We quantified activity patterns, foraging times and roost selection in the eastern blossom-bat (Syconycteris australis) (body mass 17.6 g) in coastal northern New South Wales in winter using radio-telemetry. Bats roosted either in rainforest near their foraging site of flowering coast banksia (Banksia integrifolia) and commuted only 0.3 ± 0.1 km (n = 8), whereas others roosted 2.0 ± 0.2 km (n = 4) away in wet sclerophyll forest. Most bats roosted in rainforest foliage, but in the wet sclerophyll forest cabbage palm leaves (Livistonia australis) were preferred roosts, which likely reflects behavioural thermoregulation by bats. Foraging commenced 44 ± 22 min after sunset in rainforest-roosting bats, whereas bats that roosted further away and likely flew over canopies/open ground to reach their foraging site left later, especially a female roosting with her likely young (~4 h after sunset). Bats returned to their roosts 64 ± 12 min before sunrise. Our study shows that S. australis is capable of commuting considerable distances between appropriate roost and foraging sites when nectar is abundant. Bats appear to vary foraging times appropriately to minimise exposure to predators and to undertake parental care.

The timing of the morning twilight commencement of bird song has been linked to mating, stores of food energy or territorial declarations, and is known to follow a structured, spaced order to avoid signal interference. The timing of vocalisations has been widely studied and varies with ambient and broader environmental variables, including moonlight and cloud cover. In this study, the commencement of morning song for five common species (Masked Lapwing Vanellus miles, Australian King- Parrot Alisterus scapularis, Lewin’s Honeyeater Meliphaga lewinii, Eastern Yellow Robin Eopsaltria australis and Australian Magpie Gymnorhina tibicen) and the relationship with light energy intensity were investigated on the New South Wales Midnorth Coast, eastern Australia. It was determined that each species responded to a specific threshold light intensity as a trigger to commence singing. The timing of song commencement aligned with shifts in the required threshold light level, which was influenced by environmental variables such as moonlight (earlier) and cloudiness (later for some species). It is proposed that the structured routine of the first song of some birds, during nautical twilight, is a result of evolutionary variations in their eye structure, resulting in varying perceptions of the first morning light from the sky, leading to species commencing singing at different times.

We investigated the influence of land-use history on roadside conservation values in a typical agricultural landscape of southern New South Wales (NSW), Australia. Historical information on the development of rural road reserves was collated from recently digitised 19th and 20th century pastoral and parish maps, such as road-reserve age and original survey width, as well as data relating to locations of old fence lines, county or parish boundaries, previous reserves, stock routes and road re-alignments. Ordinal regression statistics showed that road-reserve age and road width were significant predictors of roadside conservation values. Importantly, analyses showed that the first roads surveyed during the pastoral era (1840–1860s) were often of lower conservation value than roads surveyed in the 1870s, when major clearing of these landscapes commenced. Most roads were surveyed at one-chain width (20.12 m); however, pre-1870s historic roads, traveling stock routes (TSRs) and county or parish boundaries were significantly wider, decisions that have indirectly led to higher present-day conservation values. In separate analyses, historical data also formed a useful model to predict the absence of short-lived shrub species. These results highlight the influence and prevailing imprint of historical land-use on current roadside conservation values.

In July 1900, Jimmy Governor and his brother Joe commenced their murderous rampage across central New South Wales, killing nine women and children, maiming others, and raping a teenage girl. They were pursued for three months across 3000 kilometres, taunting their hunters with clues, letters and tricks. The last men in the state to be proclaimed outlaws, their pursuit and capture fascinated and terrified a nation on the eve of its Federation.
After his conviction, Governor’s execution was delayed until after the conclusion of Federation celebrations; even a fragile nation understood the perilous symbolism of launching nationhood whilst hanging a transgressive black man.
This article re-examines the crimes, evidence and trial of Governor, and the intense media reportage around them. It reveals a perpetually contested claim for control: of the family, the workplace, race, nation and empire.

In 2014 I commenced a postdoctoral project that involved collaboratively planting and maintaining a community garden on a block of land that was once part of the East Armidale Aboriginal Reserve in the so-called New England Tableland region of New South Wales, Australia. At the edge of this block of land is an introduced, invasive willow tree. In this article I write with and alongside the willow tree to interrogate the potential and limitations of anticolonial projects undertaken from colonial subject positions predicated on relations of social and environmental privilege.
Anticolonial scholarly activism demands a critique of individual and institutional complicity with ongoing colonial power structures. The following analysis offers a personal narrative of what it has been like to be involved in an anticolonial multispecies research project while working within the confines of the neoliberal university. Exploring the intersection of academic, social and environmental ecologies, I position the community garden as an alternative pedagogical and public environmental humanities research site that interrupts the reproduction of settler colonial power relations by cultivating tactics of collective resistance in alliance with the nonhuman world.
