Dissertations / Theses on the topic 'Torrens system South Australia'

Includes bibliographical references. The origins of the Torrens System of land registration are not clear. Examines the claim of Dr. Ulrich Hübbe who asserted that he collaborated with Torrens to bring about the adoption of the land law of his hometown Hamburg in the form of the Real Property Act 1858 (SA). An historical examination (collecting and analysing all relevant historical sources), shows that it is likely that Hübbe was the actual draftsman, while a comparative legal analysis (contrasting Hamburg's land law at the beginning of the 19th century with the first bill of the Act) demonstrates that there is a strong similarity between Hamburg's land registration system and the original Torrens System; and, that the outstanding differences between the systems can be explained by the natural adaptation processes which are implied by the adoption of laws.

Internationally, health systems have been undergoing an extended period of endemic change, where one effort at health system reform inevitably seems to lead to further attempts to make adjustments, re-direct the focus of the reform effort, or bring about further, sometimes very different changes. This phenomenon is described as churning in this thesis. Churning is a result of continual efforts to adjust and �improve� health systems to address intractable �wicked� problems, often through applying solutions based on neo-liberal reform agendas that have influenced public sector reform in developed countries since the early 1980s. Consistent with this, the South Australian health system has been caught up in a cycle of change and restructuring for almost thirty years. This qualitative study explores a case study of unsuccessful organisational change initiated by a group of health care agencies in the southern metropolitan area of Adelaide, South Australia, which took place between 1996 and 2001. The agencies sought to develop and establish a regional health service through a process they called �Designing Better Health Care in the South� which aimed to improve the way that services were provided in the area, and to enable the agencies to manage the increasing budgetary and workload pressures that they were all experiencing. A significant policy shift at the state government level meant that this initiative was no longer supported by the central bureaucracy and could not proceed. The agencies reverted from a focus on regional planning and service delivery to an institutional focus. The changes that are described within the scope of the case study are universally recognisable, including centralisation, decentralisation, managerialism and integration. The experience of Designing Better Health Care in the South as an unsuccessful attempt to implement change that was overtaken by other changes is also a universal phenomenon within health systems. This study locates the case study within its historical and policy contexts. It then analyses the key themes that emerge from consideration of the case study in order to understand the reasons for constant change, and the structural and systemic impediments to successful reform within the South Australian health system as an example of health systems in developed countries. As a case study of organisational change, Designing Better Health Care in the South was a story of frustration and disappointment, rather than of successful change. The case study of Designing Better Health Care in the South demonstrates the tensions between the differing priorities of central bureaucracy and health care agencies, and the pendulum swing between the aims of centralisation and regionalisation. The study uses the theory of negotiated order to understand the roles of the key themes of trust, partnership and collaboration, and power and control within the health system, and to consider how these themes affect the potential for the successful implementation of health care reform. Through analysis of the case study, this thesis contributes to an understanding of the difficulties of achieving effective reform within health systems in advanced economies, such as the South Australian health system, because of the complex power and trust relations that contribute to the functioning of the health system as a negotiated order. The study is multidisciplinary and qualitative, incorporating a number of social science disciplines including sociology, political science, historical analysis and organisational theory. Data collection methods for the study included interviews, focus groups, document analysis and a survey.

Policy-makers, funding bodies and treatment providers need current, comparable and accurate information on the activities and outcomes of alcohol and other drug (AOD) treatment services to respond to the needs of the sector. If meaningful comparisons are to be made at the jurisdictional level, a standardised treatment outcome monitoring system must be developed and implemented, that takes into account differences in client characteristics, treatment settings and modes of service provision. A brief, multi-dimensional instrument, the Brief Treatment Outcome Measure (BTOM) has been developed for routine, ongoing treatment outcome monitoring with clients receiving opioid maintenance pharmacotherapy (OMP) services in New South Wales (NSW), and for use in treatment evaluation research. This is the first time in Australia that an attempt has been made to integrate outcome monitoring into routine clinical practice across an AOD treatment sector. The BTOM contains thirty-three items across the domains of dependence, blood-borne virus exposure risk, drug use, health/psychological functioning and social functioning. The internal reliability of the BTOM is satisfactory; retest reliabilities for the measures are good to excellent and concurrent validation of BTOM scales yielded acceptable agreement. Average completion times of the BTOM were 14.5 minutes when administered by researchers and 21 minutes by clinicians. A 30-month feasibility trial was conducted in selected NSW OMP treatment agencies to determine the practicability of implementing an OMS; to identify issues that would impact on the quality of the data; and identify administrative processes that could facilitate implementation whilst minimising the burden on agency staff. In addition, clinicians who had administered the BTOM were surveyed 18 months into the trial to ascertain their attitudes towards the clinical utility, acceptability of content and the level of support given to them to administer the BTOM as part of routine clinical practice. Results from the trial indicate that the BTOM measures are sensitive to change over time; that the change observed is consistent with that reported in the OMP treatment outcome literature; and that clinicians, whilst generally being positively predisposed towards using the instrument, express concerns relating to the burden of administering and the clinical utility of conducting outcome monitoring.

The South African primary rebate is governed by Section 6 of the Income Tax Act (58 of 1962). This primary tax rebate entitles taxpayers to a tax-free income portion up to a certain level depending on the rebate amount (also referred to as the tax threshold). The concept of tax thresholds in a tax system in essence adhere to the first tax canon of Smith (1776:676), which suggests that individuals should pay taxes in proportion to each person’s ability to pay tax. The implication of this tax canon is that individuals who have a limited or no ability to pay tax should only be subject to pay tax in relation to their ability. Therefore, before tax can be levied, an amount for the necessities-of-life must be deducted from the taxpayer’s income (Vivian, 2006:85). The primary rebate system thus gives individuals a tax-free income portion which is supposed to first compensate for an individual’s necessities-of-life expenses or put differently the costs to survive. The main purpose of the present study is to critically analyse and compare the fairness of the primary rebates in South Africa in relation to other countries. To meet the main purpose a comparison was done between South Africa’s primary rebate and related government grant programs to that of Brazil and Australia. It was found that South Africa rebate system creates significant vertical and horizontal unfairness and that it compares poorly to the fairer multiple rebate and government grant systems of Brazil and Australia. Accordingly it was recommended that the unified primary rebate system of South Africa is reviewed and brought in line with the multiple rebate systems implemented in countries such as Brazil and Australia.

The thesis examines the political economy of trade policy reform in post-apartheid South Africa. It challenges mainstream accounts of contemporary trade policy in South Africa, which have advanced a solely economic rationale to explain the policy choices made by the ANC governments since 1994. The thesis argues that, far more than these accounts concede, international and domestic political economy considerations have also played a central part in the ANC governments' calculations to undertake trade reform to the degree it has. Trade reform in South Africa has been the linchpin of a global adjustment strategy pursued by the domestic political elites by which they have sought to fulfill South Africa's global, regional and domestic political and economic objectives. At the global level, the South African state has vigorously pursued trade liberalisation in order to shed its past image of international pariah and reintegrate itself into the global economy on the basis of outward-oriented growth. Restoring South Africa's international political respectability has been as important as reversing its economic marginalisation in the international division of labour. At the regional level, the South African state has used trade policy reform as a foreign economic policy tool not only to rebuild political and diplomatic relations with African countries strained during the apartheid era - but also to advance its hegemonic ambitions, particularly in Southern Africa, as well as reinforce the region's ability to engage with the forces of economic globalisation. The extent to which South Africa's regional hegemonic ambitions can be achieved, however, lies ultimately with how adeptly the country can reconcile these regional aspirations with its domestic pressures. At the domestic level, trade reform has been deployed by the decision-making elites not only to lock in the government's austere macroeconomic policy but also to curtail the power of domestic interests that have benefited from trade protectionism in the past. In return for their co-operation, the South African state has allowed these interests, notably business and labour, enhanced institutional representation in economic policymaking. In this sense trade policy has been employed to serve domestic as much as foreign political and economic policy ends.

[Truncated abstract] Indigenous Australians suffer cardiovascular disease (CVD) at a rate six times greater than the general population in Australia and while the incidence of CVD has been reduced dramatically amongst the majority of non-indigenous Australians and amongst Indigenous populations in other countries in the last 30 years, there has been little change in the figures for Aboriginal Australians, showing that heart health campaigns have little impact, for this group of people. Aims : The principal aims of this study were firstly, to determine and record the barriers to the development and delivery of CVD prevention programs amongst Indigenous Australians and secondly, to develop an alternative, effective and culturally sensitive method of delivering heart health messages. Methods and results : The study was qualitative research undertaken in three South-West towns of Western Australia where the incidence of CVD was high amongst the Aboriginal community members. The use of semi-formal interviews, informal individual consultation, observation, and focus groups were methods implemented to obtain information. The first phase of the research was to identify the barriers which affected the Aboriginal Health Workers’ ability to deliver specialist educational programs. Questionnaires and interviews with the Aboriginal Health Workers and other health professionals in the towns, and community focus groups were undertaken in this phase of the study. The second phase of the research was aimed at developing an alternative strategy for delivering heart health messages. The focus changed to adopt more traditional ways of passing on information in Indigenous communities. The idea of small gatherings of friends or family with a trusted community member presenting the health message was developed. The third phase of the research was to implement this new approach. Lay educators who had been identified within focus groups and by Aboriginal Health Workers were trained in each of the towns and a protocol involving discussions of health issues, viewing a video on CVD, produced by the National Heart Foundation, sharing in a ‘heart healthy’ lunch and partaking in a ‘heart health’ knowledge game which was developed specifically for the gatherings. Several of these gatherings were held in each of the towns and they became known as ‘HeartAware parties’.

This thesis focuses specifically on what was taught in schools in South Australia in the context of art and design education. The period covered by the study extends from the 1880s, when a Central Educational Authority was established in South Australia, to the late 1920s, when significant changes to art and design philosophies and course designs became identifiable. The nature and content of the art and design courses designed and used in South Australia is examined against an historical background of influences such as the South Kensington System of drawing and that devised by Walter Smith for the Massachusetts educational system in the United States of America. The significant contribution of Harry Pelling Gill to the teaching of art and design in schools is closely examined. It is posited that his single influence affected the teaching of art and design in South Australian schools until well into the twentieth century. The process of the study looks in detail at the overall philosophies behind the teaching of art and design, the methodologies employed and the classroom practice which pupils and teachers undertook in the pursuit of courses outlined. Issues such as methods of teacher training, correspondence courses, examinations and exhibitions are considered as these relate to the central theme of the study. The study concludes in the late 1920s, with the advent of a revised course of instruction for public elementary schools, which heralded significant changes in both the content and methodology of art and design teaching in South Australian schools.

In 2025, there will be almost 8 billion people to feed as the worlds population rapidly increases. To meet domestic and export demands, Australian grain productivity needs to approximately triple in the next 20 years, and this production needs to occur in an environmentally sustainable manner. The advent of Hi-tech Precision Farming in Australia has shown promise in recent time to optimize the use of resources. Most

Sewage pollution from humans, animal and domestic sources (land and agricultural run-off) are recognized as a major cause of deteriorating water quality along Australia's coastline. Management of water quality has primarily relied on the use of bacterial indicator methods. However the validity and source-specificity of these methods have been met with increasing reservations for several years now. A relatively recent methodology uses a different chemical biomarker approach using 'sterols', a group of compounds related to the common bio-membrane lipid cholesterol and its derivatives. Sterols can offer an additional diagnostic tool to distinguish and discriminate between sources of faecal contamination in marine, freshwater and estuarine environments in both sediments and the water column. This study investigates for the first time, the degradation of coprostanol and selected faecal sterols in 'natural' sediments from a highly mixed (marine and estuarine) sub-tropical environment following a simulated pollution event (primary effluent); the use of faecal sterols as an additional indicator for determining non-point source sewage discharges at popular anchorages in the Moreton Bay and Gold Coast Broadwater system; and the use of sterol ratios in the determination of the fate and transportation of nutrients from a Sewage Treatment Plant (STP) point-source outlet pipe during plant malfunction. The microcosm degradation experiment revealed that faecal and selected sterols are continually synthesised and degraded over time by auto- and hetero trophic organisms within the sediment matrix. Coprostanol was the only sterol to degrade continually, with only minor fluctuations over a time period of two months. Results from this degradation experiment further revealed a sharp decline of coprostanol within the first week. From this it could be concluded that, without any further addition, external inputs of coprostanol are reduced to background levels within this time period. Therefore, removal of coprostanol after six days was 94% and 73% in mud and sand, respectively. The removal of coprostanol was much higher in mud than sand, reflecting a higher level of microbial activity in muddy sediments for assimilation of sterols. The field study undertaken at popular anchorages in Moreton Bay and the Gold Coast Broadwater revealed extremely low levels of sterols and bacterial indicators over both a spatial and temporal scale consistent with a shallow, oligotrophic, highly dynamic sand dominated system. Even though sterols analysed were found at extremely low levels (mostly in the nano-gram range), they were found to be highly correlated and were successful in identifying an unexpected once off pollution event from a point source at Moreton Bay Island. Other than this one incident, both sterol and bacterial levels were consistently low even when anchorages were at full capacity. Thus, sewage from recreational vessels was found to have very little, if any, effect on the water quality at anchorages in Moreton Bay and Gold Coast Broadwater. The point-source study conducted during a local sewage treatment plant malfunction revealed that even though absolute concentrations of sterols did not change during this event, the distribution of sterols within the samples changed, hence changing the sterol ratios. Further, nutrients (mainly nitrogen) can be transported several kilometres by currents, flocculate out of the water column and settle out into the sediment in areas with low tidal and hydrological flushing. There, the nutrients can cause in situ production of sterols in sediments changing sterol ratios. Overall, this study revealed that analyses of sterol biomarkers have the potential to indicate nutrient inputs (such as nitrogen) as well as sewage, post-hoc pollution events at extremely low levels/high dilutions in coastal sediments.

ENGLISH ABSTRACT: The traditional ways in which manufacturers of crop protection products exercised control over distribution systems have diminished in their impact. Control was based on quality products, the power of the brand, an installed customer base and a broad portfolio of mostly patented products. Manufacturers of crop protection products need to review the manner in which these products are marketed, which distribution system management models are to be used, and the importance that is placed on distribution system management in the marketing mix. The primary aim of this study was defined as: "The development of appropriate distribution system management models for application in South Africa and Australia~. The secondary aim was defined as: "Establishing the key factors which determine the relationship between manufacturers and distributorsn . The dominant economic characteristics of the global crop protection industry are deemed to consist of a global market valued at US $28,090 mio, a mature market in a decline phase, the rapid consolidation of industry players, increased generic product manufacturer activity and an overall decline in manufacturer profitability. In South Africa crop protection product manufacturers use approximately 46 independent distributors to market products on farms through 600 affiliated commissioned sales agents. In Australia the distribution of crop protection products is much more concentrated. Distribution is essentially controlled by five national distributors and their coupled salaried representatives. Manufacturers therefore rely on third parties for the marketing of their products to farmers in both countries. The applicable problem statement has been formulated to select a distribution system management model that will: (i) optimally balance direct distribution related cost and subsequent levels of control over distributors; (ii) maximise the probability that a distributor will buy and actively promote the complete product portfolio of a for high levels of interpersonal relationship maintenance; and (vi) manufacturers have to instill the philosophy that distribution system management is part of a manufacturer's strategic business and marketing focus and not simply a task to be performed by a third party.
AFRIKAANSE OPSOMMING: Die tradisionele maniare waarop die vervaardigers van oesbeskermingsprodukte beheer kan uitoefen oor verspreidingsisteme is nie meer so suksesvol nie. Beheer was gebaseer op kwaliteil produkte, die mag van die handelsmerk:n gevestigde klientebasis en 'n wye produktereeks,bestaande uit gepatenteerde produkte, Vervaardigers van oesbeskermingsprodulcte moet die wyse waarop hierdie produkte bemark word, watter verspreidingsisteem bestuursmodelle gebruik word en die belangrikheid wat geplaas word op die bestuur van die verspreidingsisteme in die totala bemarkingspoging in heroorweging neern. Die primere doelstelling van hierdie studie is: "Die ontwikkeling van toepaslike verspreidingsisteem bestuursmodelle vir toe passing in Suid-Afrika en Australia. "Die sekondere doelstelling is: "Die vas stelling van die sleutelfaktore wat die verhouding tussen velVaardigers (verskaffers) en verspreiders bepaar. Die dominante ekonomiese kenmerke van die globale oesbeskermingsindustrie is 'n markwaarde in VSA $ 28,090 miljoen, 'n stagnante mark in 'n agteruitgang lase, die drastiese konsolidasie van die industrie spelers, 'n toename in die aktiwiteite van die generiese produkvervaardigers en 'n algemene daling in die winsgewindheid van die vervaardigers. In Suid-Afrika gebruik die vervaardigers van die oesbeskermingsprodukte ongeveer 46 onafhanklike verspreiders om die produkte op plaasvlak te bemark met behulp van 600 geaffilieerde kommissie agente. Die verspreiding van oesbeskermingsprodukte is baie meer gekonsentreerd in Australie. Verspreiding word in wese beheer deur vyf nasionale verspreiders en hulle spanne van verkoopsteenwoordigers wat 'n salaris verdien. In beide lande moet velVaardigers van oesbeskermingsprodukte staatmaak op onafhanklike instansies vir die bemarking van hul produkte op plaasvlak. Die probleemsteiling is dus die uitdaging om 'n verspreidingsisteem bestuursmodel t9 ontwikkel wat: (i) . n optima Ie balans sal gee tussen direkte verspreidingskoste en gekoppelde vlakke van beheer oor verspreiders; (ii) die waarskynlikheid dat . n verspreider die betrokke produkreeks van die vervaardiger sal aankoop en aktief sal promoveer; (iii) dit kan bereik in . n mark waar verspreiders talle bronne het van soortgelyke produkte teen kompeterende pryse. Gebaseer op die sekondere navorsing wat gedoen is wit dit blyk dat daar 'n algemene konsensus is dat daar n nei9in9 weg is van transaksie spesifieke besigheidsverhoudings na besigheidsverhoudings gebaseer op vennootskap gebaseerde benaderings in die interaksie tussen vervaardigers (verskaffers) en verspreiders. Hierdie tipe besigheidsverhouding word gekenmerk deur hoe vlakke van onderlinge vertroue, wedersydse verbintenis, konflik hanteringsmeganismes en goeie wedersydse kommunikasie. Primere navorsing is in Suid-Afrika (253 respondente) en Australia (180 respondente) gedoen. Implikasies vir die konstruksie van verspreidingsisteem bestuursmodelle wat voortvloei uit hierdie navorsing sluit in die belangrikheid dat on vervaardiger on wye en gesogte produkreeks het, die vereiste dat produkte beproefde effektiwiteit het, produkte kompeterend geprys is, die vereiste vir hoe vlakke van verskaffer opvolgdiens en die vereiste vir goeie interpersoonlike verhouding tussen werknemers van beide die vervaardigers en die verspreiders. Hierdie elemente moet ondermeer gerugsteun word deur goeie kommunikasiesisteme. Die "idea Ie" verspreidingsisteem bestuursmodelle is vervolgens voorgestel vir beide Suid-Afrika en Australie, gebaseer op die bevindinge van ondermeer die sekondere- en primere navorsing. Hierdie mode lie het ten doel om toepaslike strukture en besigheidsbenaderings vir vervaardigers daar te stel om hulle behulpsaam te wees om die geidentifiseerde behoeftes van die verspreiders aan te spreek.

Taiwan land registration system is a land registration system established after inheriting the spirit of the German rights registration system and the connotation of the Australian Toulouse land registration system. This not only fills the damage caused by land registration in the German rights registration system, but also strengthens the mandatory nature of the Torrens land registration system. Among them, the most important mechanism introduced is the damage compensation for the land registration system in Torrens, Australia. When there are other problems caused by land registration errors, omissions, etc., causing damage to the right holder, if the damage can be attributed to the registrant or the registration authority, the state will first compensate for the damage. If it is attributable to the registrar, the State has recourse to the registrar. However, no matter whether it is a light or heavy punishment, there is no small pressure on the registered personnel, because the registration of the official duties is in accordance with the legal procedures, but it is responsible for the burden of compensation, which leads to the flow of land registration personnel. In contrast, in the Australian Torrens system, in order to take into account the interests of the people and the protection of registered personnel, the Torrens Guarantee Fund has been specially set up to specifically compensate for all registration damages, reducing the pressure on the registration personnel to make the land registration process smoother and faster. It will not let the people claim nowhere in the process of being damaged by the registration process. The purpose of this study is to explore the origin and connotation of damage compensation for the Torens land registration system in Australia, and to understand the damage compensation for land registration and the protection of various land rights in the Torrens system, and then to explore the land registration damage in Taiwan. The solution to the problem of liability.

Thermal stratification occurs in shallow water bodies because solar energy separates the water column into an upper warm layer, a lower cold layer, and an intermediate layer between the upper and lower layers. In general the intermediate layer exhibits a significant thermal gradient over depth. Because cold water is heavier than warm water, this temperature structure produces a stable stratification, thereby inhibiting circulation from the bottom to the surface. This stable stratification results in a deficit of dissolved oxygen in the lower layer leading to water quality problems. Hence understanding the thermal structure and vertical circulation in shallow water bodies is important for water quality and its management. In this research, a numerical code is developed to examine the three-dimensional flow structure in shallow water bodies. This numerical code is used to solve the governing equations : the Reynolds averaged Navier-Stokes equations for three velocities and pressure, the depth-averaged continuity equation for free surface movement, the equations for turbulence closure, the scalar transport equation for temperature, and the international equation of state for density variation due to temperature. These equations are solved simultaneously using a finite difference method. The mathematical equations are transformed into a generalised coordinate system which allows flexibility for irregular boundaries and the allocation of vertical grid points every time step depending on free surface movements. In order to overcome possible numerical instabilities because of the small vertical length scale in shallow water bodies, an implicit method is used in the vertical direction. Several test cases involving free surface movement are used to verify the numerical code, and numerical solutions compare favourably against analytical solutions and measured data. The numerical code has been applied to the Torrens Lake in Adelaide, South Australia, where algal blooms occur frequently in summer due to thermal stratification. Typical thermal structures have been obtained from the model and these are compared with field data. The current code has been developed to improve upon existing commercial models which may not adequately address shallow water flows because of the high computational burden required to resolve free surface movements and consequential difficulties encountered for models with a small vertical length scale.

This study is an examination of residential mobility and its outcomes focussing on the forced relocation of public housing tenants from The Parks area of metropolitan Adelaide. In Euro-American countries, this type of residential mobility is increasingly used as a means of facilitating urban regeneration and countering the effects of the ongoing decrease in local public housing stock. The result is growing numbers of public tenants affected by relocation. The study agues that these public tenants have the right to a basic level of residential satisfaction, and in order for this satisfaction to be provided; the conditions and character of its formation must be understood. The thesis examines residential mobility and the formation of residential satisfaction to provide a basis for understanding the outcomes and effects of relocation, who is most affected, and how to target solutions to improve the relocation process. Despite the fact that households experience similar influences, and make their residential decisions in largely predictable ways, the formulation of residential satisfaction and the effects of relocation are highly individualised. Successful relocation is shown to be dependent on the inclusion of tenants' expert knowledge about their own residential satisfaction; this means that resident involvement in the process is crucial. This thesis investigates a means of combining these findings to improve the outcome of the relocation process for each individual tenant and their household. A prototype Spatial Decision Support System (SDSS) is constructed to allow relocating tenants to participate in their own relocation decision process. This SDSS allows local, spatially referenced information to be combined with each tenants own expert knowledge. This information is combined through a structured decision process, which is presented in a portable computer program with a simplified user interface. This SDSS is tested by relocating tenants and key stakeholders from The Parks to evaluate its usefulness in improving the relocation process.

Water is precious, particularly in South Australia, the driest State in Australia, with over 80% of its land area receiving less than 250mm of rainfall per year. Security of water supply has always played a critical role in the economic and social development of South Australia, and will continue to do so while dependency on water from the River Murray is so high and there is competition over this from states and for different uses – municipal, irrigation, industry, and the environment. The drive towards sustainable development has evolved to attenuate overconsumption of the world’s natural resources of which water is a key element. Provision of reliable water supplies to regional South Australia has always presented challenges, given the vast distances involved and the limited number of natural water sources. Despite these, a majority of South Australians enjoy the benefit of a reliable and safe water supply, adequate waste disposal system, good community health and high standard of living. A challenge remains to determine the sustainability of current major water pipe transfer systems from remote resources to small communities. There may be scope for managing existing water supplies more effectively and further developing local water harvesting and reuse solutions to minimise the need for more significant infrastructure investment. This study investigates the challenges and opportunities for extending development of non-potable (secondary) water supply schemes in South Australian towns. These schemes will conserve the State’s freshwater resources. The primary focus of this study is harnessing stormwater runoff and treated effluent generated by normal township development to supplement higher quality public water for uses such as irrigation of public areas and sporting fields in country areas. Water harvesting and reuse is not likely to occur due to some technological breakthrough but through application of known technology and the adoption of water conscious ethics by society. However, it is a sensible reality for the South Australian climate, particularly when coupled with appropriate conservation and suitable landscaping practices. Thus, the major theme of this study is information sharing since if people are familiar with and understand the concepts then more communities may be encouraged to develop their resources. Water reuse has proven to be a beneficial strategy for addressing stormwater runoff and wastewater disposal problems and alleviating localised water supply problems for several South Australian towns and communities. The existing projects demonstrate both the strong community-based and innovative approach to water resources management in this state. They are inherently simple in form, and can often be assembled with readily available materials by people with a basic understanding of plumbing and construction skills (locally available). The potential for localised water harvesting and reuse in South Australian towns is generally limited to single purpose communal non-potable systems. Further, it is likely to only be sustainable in rural communities willing to make a commitment to its long term, proper operation and maintenance, or they could endanger public health.

Reservoir quality of subsurface sandstones depends on the composition, texture and grain size of the initial sediments. These factors are a function of hinterland processes: tectonic setting, provenance, climate and depositional environment, and sediment transportation processes. This study focuses on a modern, dryland, fluvial deposition system from source-to-sink that aims to provide a quantitative dataset analogue to facilitate forward modelling for prediction of subsurface compositions, grain size and textures of reservoir sandstones. Umbum Creek, in the western Lake Eyre Basin of Central Australia, was selected as a small river network (~ 100km²) in order to study source-to-sink sedimentation. The provenance area was analysed using isopach maps derived from a 783 drill-hole dataset, which included stratigraphy and lithology information. Subsequently forty-three samples of different provenance lithotypes from the Umbum Creek catchment were collected for petrographic thin-section analysis. Recent sediments were then sampled from 90 strategically located stream confluences along Umbum Creek and tributaries (proximal, medial and distal subsets). A quantitative textural and compositional dataset was subsequently generated from 34 selected samples. With half-phi sieve analysis (4mm to 32 microns), and an associated petrographic description recognising 72 categories of grain composition was undertaken for each sample. The provenance analysis using isopach maps demonstrated that Palaeozoic and Mesozoic sedimentary basin evolution in the study area was controlled by northeast and northwest-trending structural elements. The regional uplift of the Peake and Denison Inliers that occurred during the Cenozoic had a significant impact on the evolution of the Lake Eyre Basin, causing changes in the provenance of Late Neogene sedimentation and on through to the present. The sink area represents a shallow intracratonic basin whereby a thin veneer of fluvial/lacustrine sediments is accumulating adjacent to a basement uplift. This study has highlighted the importance of multiple sediment provenances. Five different provenance lithotype grains were identified in the Umbum Creek modern sediments: the Gawler Craton plutonic / basement provenance (recycled) the Peake and Denison Inliers Proterozoic volcanic provenance (recycled), the Davenport Ranges metamorphic provenance, the Mesozoic sedimentary provenance and the Cenozoic sedimentary provenance. Whereas a downstream fining of grain size was expected, a general trend of downstream coarsening of grain size was noted being the result of aeolian deflation of fines and intra-basinal coarse-grained sediment contributions. In the sink area, modern sediments from the terminal splay complex comprise 70-80% quartz, 10-20% lithic fragments (of which ~ 7% are ductile lithic grains), < 3% feldspar, and clay (<2%). Grains are sub-angular to well-rounded and moderately well sorted. The compositional and textural maturity of the terminal splay sediments is attributed to reworked plutonic quartz grains, the dissolution and disintegration of feldspar and carbonate grains during transportation, along with the breakdown of lithic fragments due to fluvio-aeolian interactions and subsequent mechanical/ chemical weathering processes. These data were used to build a predictive forward model for modal sandstone analysis that achieved a fair to good correlation between predicted and observed grain lithotypes and provenance categories. These results illustrate that the character of sands in the Umbum Creek catchment are governed by a multiplicity of controls such as tectonic setting, provenance lithotype analysis, climate, regional topographic gradient, hinterland transport distance, basin subsidence rate and depositional environment. The fluvio-aeolian depositional environment along with the current arid to semi-arid playa climatic conditions of Umbum Creek catchment facilitate the growth of clay coatings, however accounts for a low clay matrix within the deposits. In addition, the playa environment also facilitates the alteration of infiltrated detrital clay to kaolinite, the formation of evaporites (gypsum, halite and anhydrite) and the formation of authigenic clays. These factors are all significant in determining the ultimate reservoir quality of reservoir sandstones, emphasising the importance of this study as an analogue for modelling ‘buried’ dryland depositional systems.
