Common reed Phragmites australis is the dominant vascular plant species of the shorelines of the Gippsland Lakes, south-eastern Australia. Although substantial declines have been reported for over 50 years, with increasing salinity posited as the cause, P. australis still occurs around the Gippsland Lakes, including in environments with near-oceanic salinities. The occurrence of P. australis in highly saline environments cannot be explained in terms of either seasonal variations in surface water salinity or a freshwater subsidy provided by intrusions of non-saline groundwater into the root zone. An experimental growth trial with plants of different provenance showed that P. australis grew vigorously even at 8–16PSU (with maximum aboveground biomass at 2–4PSU). There was some evidence that specimens from saltier sites were more salt tolerant than those from fresher sites. The selection of salt-tolerant strains is the most likely explanation for the occurrence of P. australis in saline sites. However, anthropogenic salinisation is unlikely to be the only factor involved in the historical loss of reed beds, and lower and more stable water levels following the permanent opening of the Gippsland Lakes to the ocean in 1889 are probably also contributing factors.

Abstract. This study describes the foraminiferal biofacies of a temperate stenohaline shelf and associated euryhaline marine lakes of Gippsland in southeast Australia. The study incorporates facies analyses and interpretations of three types of foraminiferal distributional data: forms alive at the time of collection, recently dead forms and relict forms. Four principal biofacies types occur: (1) the euryhaline marine Gippsland Lakes silts and sands; (2) inner shelf medium to coarse quartz-rich sands and bioclastic silty sands; (3) medium shelf bryozoan-rich bioclastic silt and silty sand; (4) outer shelf bryozoan- and plankton-rich silts and fine sands.The euryhaline marine Gippsland Lakes silts and sands contain abundant Ammonia beccarii and Eggerella, with minor Quinqueloculina, Elphidium and Discorbinella. The Gippsland inner shelf biofacies (0–50 m depths) consists of medium to coarse quartz-rich sands and bioclastic silty sand. Abundant living, relict and recently dead miliolids occur in the inner shelf with rare planktonic forms. Common planktonic foraminifera, with Cibicides, Parrellina, Elphidium and Lenticulina and relict forms occur in the bryozoan-rich bioclastic silt and silty sand of the Gippsland middle shelf (50–100 m depth). Bryozoan and plankton-rich silts and fine sand occur in the outer shelf to upper slope facies (100–300 m) below swell wave base on the Gippsland Shelf. A diverse fauna with common textulariids, Uvigerina, Bulimina, Anomalinoides and Astrononion and rare relict forms, occurs in this biofacies. Planktonic foraminifera and Uvigerina are most abundant at the shelf break due to local upwelling at the head of the Bass Canyon.Estimates of faunal production rates from live/dead ratios and full assemblage data suggest that the fauna of the Gippsland Shelf has not been significantly reworked by wave and/or bioturbation processes. Most relict foraminifera occur in the inner shelf, with minor relict forms in the middle to outer shelf. This pattern is similar to other shelf regions in Australia, where shelf areas were exposed during Pleistocene lowstand times, principally reworking pre-existing inner to middle shelf faunas. Correspondence analyses of the foraminiferal data yield a clear depth-related distribution of the faunal assemblage data. Most of the modern Gippsland Shelf fauna are cosmopolitan species and nearly a third are (semi-)endemic taxa suitable for regional palaeo-environmental studies. From biostratigraphic studies it is clear that the modern Gippsland foraminiferal assemblage evolved since Early Miocene times, with most elements present by the Late Miocene. Hence, the Recent Gippsland Shelf foraminiferal biofacies distribution is a good analogue for Neogene palaeo-environmental studies in the region. The longer ranging pre-Miocene mixture of epifaunal and infaunal taxa are deeper shelf cosmopolitan forms and are inferred to be more conservative since they evolved in relatively lower stress environments, typifying mesotrophic to eutrophic conditions compared to inner shelf epifaunal forms with ecological niches markedly affected by sea-level and temperature fluctuations in zones of constant wave action, in oligotrophic environments.The foraminiferal and facies analogues of this study on the Gippsland Shelf can be used for palaeo-environmental analyses of the Gippsland and Otway Neogene sedimentary successions. Such improvements will lead ultimately to a better understanding of the evolution of the neritic realm in southeastern Australia, an area facing the evolving Southern Ocean during the Cenozoic.

Abstract. Blooms of noxious N2 fixing cyanobacteria such as Nodularia spumigena are a recurring problem in some estuaries. Here we report the results of a palaeoecological study on a temperate Australian lagoon system (The Gippsland Lakes) where we used stable isotopes and pigment biomarkers in dated cores as proxies for eutrophication and blooms of cyanobacteria. Pigment proxies show a clear signal, with an increase in cyanobacterial pigments (echinenone, canthaxanthin and zeaxanthin) in the period coinciding with recent blooms. Another excursion in these proxies was observed prior to the opening of an artificial entrance to the lakes in 1889, which markedly increased the salinity of the Gippsland Lakes. A coincident increase in the sediment organic carbon content in the period prior to the opening of the artificial entrance suggests the bottom waters of the lakes were increasingly stratified and hypoxic, which would have led to an increase in the recycling of phosphorus. After the opening of the artificial entrance there was a ~ 60 year period with low values for the cyanobacterial proxies as well as a low sediment organic carbon content suggesting a period of low bloom activity associated with the increased salinity of the lakes. During the 1940s, the current period of re-eutrophication commenced as indicated by a steadily increasing sediment organic carbon content and cyanobacterial pigments. We suggest increasing nitrogen inputs from the catchment led to the return of hypoxia and increased phosphorus release from the sediment, which drove the re-emergence of cyanobacterial blooms.

Vessels cause considerable disturbance to cetaceans world-wide, with potential long-term impacts to population viability. Here we present a comprehensive review of vessel impacts to cetacean behavior in Australian waters (2003–2015), finding inadequate protections to be in place. The majority of these studies found trends of decreased animal travel and resting behavioral states as well as low compliance to regulations, and they recommended further regulatory action such as greater enforcement or monitoring, or passive management strategies. As a case study, we conducted the first field assessment of vessel compliance with the Wildlife (Marine Mammal) Regulations 2009 in Gippsland Lakes, Australia, and provide the first assessment of the endangered Gippsland Lakes Burrunan dolphin (Tursiops australis) population’s behavioral ecology. Dolphin behavior and vessel regulation compliance data were collected during boat-based surveys of Gippsland Lakes from July 2017 to January 2018, with a total of 22 dolphin group sightings resulting in 477 five-minute point samples. 77% of dolphin sightings involved vessel interactions (within 400 m), and 56 regulation breaches were observed. These breaches were most severe in summer (mean = 4.54 breaches/hour). Vessels were found to alter dolphin behavior before, during, and after interactions and regulation breaches, including increased mating (mate guarding) and milling behavioral states, and increased ‘fish catch’, ‘high leap’ and ‘tail slap’ behavioral events. These behavioral changes may indicate masking of the dolphins' acoustic communication, disturbance of prey, increased dolphin transition behaviors, and/or induced stress and changes to group structure (including increased mate guarding). While our results provide evidence of short-term altered behavior, the potential for long-term effects on population dynamics for this threatened species is high. In the context of reported inadequate cetacean protection Australia-wide, our management recommendations include greater monitoring and enforcement, and the utilisation of adaptive management.

Environmental context. Eutrophication can lead to the production of harmful algal blooms and is one of the world’s most serious water quality issues. Phosphorus is potentially the limiting macro-nutrient in fresh, estuarine and some marine waters. Consequently, it plays a crucial role in determining the ecological status of many aquatic ecosystems. Considerable effort has been invested in monitoring dissolved reactive phosphorus and total phosphorus in the water column, but less is known about the speciation of phosphorus, particularly in the sediment. This compartment is an important and dynamic reservoir of phosphorus and a potential long-term source of phosphorus release to the water column by the sediment–water interface. This paper investigates the solid-phase speciation and reorganisation of phosphorus within the sediments of a shallow lake system in south-east Australia (the Gippsland Lakes) which suffers from recurring harmful algae blooms. Various strategies are proposed to determine the minimum realistic timescale required to deplete the sediment of labile and reactive phosphorus species. Abstract. Solid-phase phosphorus pools in the sediments of two shallow lakes (Wellington and Victoria) in the Gippsland Lakes coastal lagoon system of south-east Australia are discussed. Cores (20-cm depth) were taken in summer and winter in both lakes and a sequential extraction scheme (SEDEX) was used to profile the exchangeable P (Pex), iron oxide/hydroxide bound P (PFe), authigenic P (Pauth), detrital P (Pdet) and organic P (Porg). Pore-water (Ppw) dissolved reactive phosphorus concentration profiles were also measured. The dominant forms of P were PFe (up to 53%) and Porg (35–55%), with the PFe fraction playing a key role in the short-term retention of P in the sediment. Benthic phosphorus fluxes at the sediment–water interface (μmol m–2 d–1) were determined from the sequential extraction data. The results were compared with flux measurements from the complementary approaches of benthic chamber experiments and Fickian diffusion calculations, to allow an insight into the nature and seasonal variations of the fluxes. The burial flux of phosphorus was also estimated from excess 210Pb profiles in the sediment of the lakes. All of these data were used to produce a phosphorus budget for the Gippsland Lakes which suggested that the sediment represents a substantial source of phosphorus within the lakes and thus clearly highlights the importance of the sedimentary compartment in shallow eutrophic ecosystems. Minimum realistic timescales for complete labile phosphorus depletion from the sediment (assuming no resupply from the sediment–water interface) were calculated and ranged from 8 to 22 years.

The Gippsland Lakes, listed under the Ramsar Convention in 1982, have undergone chronic salinisation since the cutting in 1889 of an artificial entrance to the ocean to improve navigational access, exacerbated in the mid–late 20th century by increasing regulation and extraction of water from inflowing rivers. Both developments have had substantial ecological impacts: a marked decline in the area of reed (Phragmites australis) beds; the loss of salt-intolerant submerged taxa such as Vallisneria australis, causing a shift to a phytoplankton-dominated system in Lake Wellington; and, nearer the entrance, an expansion in the area of seagrasses. Mangroves (Avicennia marina) first appeared in the late 1980s or early 1990s. Since 1986 recurring blooms of Nodularia spumigena have led to loss of recreational amenity and to the periodic closure of recreational and commercial fisheries. Changes to hydrological and salinity regimes have almost certainly shifted the contemporary fish community away from the pre-entrance state. Rises in eustatic sea levels and increases in storm surges will exacerbate the issue of chronic salinisation. Whether or not managers choose to intervene to prevent, or at least minimise, ongoing environmental change will inevitably prove controversial, and in some cases no socially or technologically feasible solutions may exist.

The Gippsland Basin is an asymmetric graben which initially formed during the break-up of Australia and Antarctica in the Early Cretaceous. During continental rifting the basin was filled by volcano-clastics of the Strzelecki Group. The overlying alluvial sediments of the Golden Beach Group represent a second phase of rift fill associated with the Tasman Sea rift. Following continental break-up in the Campanian, the Latrobe Group was deposited as a transgressive sequence of marine and coastal plain sediments. Thermal subsidence from the Oligocene to Recent was accompanied by the deposition of marine marls and limestones of the Lakes Entrance Formation and Gippsland Limestone.A north-south cross-section through the basin, based on regional seismic data and nine exploration wells, has been used to study the tectonic, thermal and basin-fill history. A detailed basin subsidence history based on a crustal rifting model was constructed, constrained by stratigraphic data and palaeo-water depth estimates at well locations. The history of sedimentation was then modelled by a Shell proprietary package, using the subsidence history and published eustatic sea level variations. This numerical model is based on a forward time-stepping scheme using semi-empirical algorithms to define the facies deposited. The gross basin architecture of the Gippsland Basin is successfully reproduced by the model. In addition the model details the timing and extent of marine incursions in the Golden Beach Group and the eustatic control on facies patterns in the Latrobe Group.The method has potential for predicting the sedimentary facies in undrilled parts of the Gippsland Basin and in frontier areas in general.

There is a need for ecological modelling to help understand the dynamics in ecological systems, and thus aid management decisions to maintain or improve the quality of the ecological systems. This research focuses on non linear statistical modelling of observations from an estuarine system, Gippsland Lakes, on the south-eastern coast of Australia. Feed forward neural networks are used to model chlorophyll time series from a fixed monitoring station at Point King. The research proposes a systematic approach to modelling in ecology using feed forward neural networks, to ensure: (a) that results are reliable, (b) to improve the understanding of dynamics in the ecological system, and (c) to obtain a prediction, if possible. An objective filtering algorithm to enable modelling is presented. Sensitivity analysis techniques are compared to select the most appropriate technique for ecological models. The research generated a chronological profile of relationships between biophysical parameters and chlorophyll level for different seasons. A sensitivity analysis of the models was used to understand how the significance of the biophysical parameters changes as the time difference between the input and predicted value changes. The results show that filtering improves modelling without introducing any noticeable bias. Partial derivative method is found to be the most appropriate technique for sensitivity analysis of ecological feed forward neural networks models. Feed forward neural networks show potential for prediction when modelled on an appropriate time series. Feed forward neural networks also show capability to increase understanding of the ecological environment. In this research, it can be seen that vertical gradient and temperature are important for chlorophyll levels at Point King at time scales from a few hours to a few days. The importance of chlorophyll level at any time to chlorophyll levels in the future reduces as the time difference between them increases.

Nodularia spumigena is an estuarine cyanobacteria that produces the toxin nodularin. This toxic cyanobacteria is known to have caused death to domestic and wild animals and is recognised as dangerous to human health. N. spumigena causes harmful algal blooms in many parts of the world including Australia. The toxic solutes of N. spumigena are potentially dangerous when contact is made to contaminated water bodies or is ingested by primary consumers. In Australia blooms of N. spumigena are common in the Gippsland Lakes in South-eastern Victoria and cause socio - economic hardships to the local communities. This PhD investigates the toxic effects of N. spumigena and its solutes to a range of aquatic life. A method known as SPME - HPLC showed promise in environmental monitoring of N. spumigena toxins by measuring nodularin from water samples. Other research presented study into the lethal and sublethal effects of on an extract from N. spumigena to aquatic fauna. Resu lts showed the N. spumigena extract was not lethal to many aquatic fauna although zooplankton from the Gippsland Lakes showed mortality at environmental relevant levels. Biochemical studies focusing on animal detoxification and antioxidation enzymes and DNA integrity showed sublethal effects to the N. spumigena extract. Results presented in this thesis show that an extract of N. spumigena elicited detoxification and antioxidation responses in animals tested. Furthermore, the use of the COMET assay showed increased damage to DNA of animals tested. Results also showed that different organs in animals tested responded differently to the aqueous extract, suggesting mode of uptake maybe important in toxicosis. Further, feeding studies with N. spumigena help elucidate mode of uptake using enzyme response biomarkers. The overall results of this research provided an assessment of the toxic affects of N. spumigena on aquatic fauna with special reference to the Gippsland Lakes, Victoria, Australia.

Integrated coastal management (ICM) has been the basis for coastal planning and management since the 1970s. The theory and practice of ICM is based on the premise that increased integration of planning and management in the coastal zone will lead to improved environmental and social outcomes for the coast. In the context of global and national trends, this thesis examines the application of ICM in three place-based coastal case studies in Victoria: the Gippsland Lakes, Point Nepean and the Geelong region. The particular focus is on the twin challenges of coastal urbanisation and the impacts of climate change. Through a wide range of applied research techniques including focus groups, the research explores the pressures, issues, impacts and implications for ICM and beyond. The case studies point to a number of important implications for ICM and identify opportunities for a more sustainable approach to coastal planning. In reviewing the research findings, a set of five steps and six principles are proposed to respond to policy failures and provide for a transition to more sustainable coastal planning in Victoria. The five steps involve expanding the theory of ICM to be outcome based and regional in its approach to coastal planning and management. In the context of climate change, a more adaptive and systems approach has been incorporated along with recognising the even greater importance of community engagement in coastal planning processes during a period of increased uncertainty and change. The principal instrument for change is a tripartite intergovernmental agreement on sustainable coastal planning underpinned by a set of six principles. These include: agreed and shared outcomes for the coastal environment to facilitate horizontal and vertical integration; an adaptive and systems approach integrating science and urban planning drawing on experience and knowledge in both disciplines; incorporation of the shared outcomes and an adaptive approach into urban and regio nal planning systems for local implementation; regional governance arrangements for integration of policy outcomes and community involvement; capacity building for sustainable coastal planning including interdisciplinary research and community education and long term monitoring and evaluation. The transition from ICM to sustainable coastal planning does not discard ICM but rather incorporates its strengths and adapts the concept to meet the twin challenges of coastal urbanisation and climate change. Further research questions are posed to indicate how the research findings could be further developed as part of a future coastal research agenda. The research findings seek to make a contribution to the theory and practice of ICM to build a pathway to coastal planning for the benefit of our coast and future generations.

The subject matter of this thesis spans the disciplines of Geography, Prehistory and
Anthropology in attempting to examine the interaction of environmental and socio-cultural
systems. The thesis is not meant to be primarily be an in-depth study of the evolution of the
Gippsland Lakes system but is concerned with the question of the nature of the interaction
of a small-scale society with its environment and how this is reflected in the cultural forms
of the society.
That is, rather than being the focus of the study, reconstruction of changes in the
environmental parameters of the field area over time is undertaken to support the primary
inquiry into the nature of environmental-cultural interaction. The goal of the study is
therefore to examine cultural process rather than sedimentary processes.
This empirical approach tests the correlation between the evolving landscape and the
archaeological and ethnographic cultures of the Quaternary barrier systems of the
Gippsland Lakes-Ninety Mile Beach region. This involves environmental reconstruction
largely using published geomorphological and palynological information, and extensive
archaeological site survey and analysis to develop an outline of the prehistory of the study
area. Ethnographic and ethnohistoric reconstruction of aspects of the historical sociocultural
organisation of the area are undertaken in order to provide a comparative base for
archaeologically reconstructed culture. The study identifies a number of problems with the
use of the rich ethnography of the area.
Use of information hinges upon its validity and reliability. For these reasons sources of
bias, particularly natural factors working upon the archaeological record, are investigated.
These have considerable implications for the design and execution of survey, and for
interpretation and analysis of results. It appeared that in the study area at least statistical
description of site location data could not be carried out validly. It was also concluded that
ethnographic accounts of the study area must be used with caution.
Shifts in the natural environment and cultural change in the area seemed to show a poor
correlation. This gave rise to the conclusion that much of what is seen in the reconstructed culture history is attributable to wider scale movements of cultural information in
prehistory rather than to the details of the evolution of the local environment. Upon closer
examination it can be seen that this picture alters according to the scale at which it is
viewed.
There have been major spreads of information, including technological information,
which lead to economic and therefore ecological changes through the Holocene. This
expansion of ideas involved the proliferation of microlithic technologies in the mid-
Holocene, and in the later Holocene a wide-spread expansion of such technologies as fishing
hooks and tied-end canoes. As these phenonema also occurred beyond the study area it is
invalid to attribute them to local adaptive processes.
It is argued that the later Holocene developments, facilitated by technological innovation,
could have been induced by landscape evolution including estuary and wetland
sedimentation and evolution of other, rocky, coasts. At a closer scale, it can be seen that
within these trends local aspects of Holocene Aboriginal culture were closely adjusted to
local environmental conditions. Thus while gross configurations of local culture owe much
to broad scale historic processes, allowed or induced by large scale environmental
evolution, details of local culture may be explicable in terms of local conditions. At either
scale conscious perception and culturally informed response are indicated, and changes
must be seen as significantly induced rather than as the outcomes of random evolutionary
processes.
The concept of adaptation to environment is also examined from a theoretical perspective,
and the use of models of adaptation derived from neo-Darwinian theory in examination of
culture process is scrutinised. It is concluded that the application of an evolutionary model
based on natural selection to cultural process cannot be supported. A process of cultural
selection is suggested as a more valid model in the evolution and reproduction of sociocultural
systems.

This thesis explores a new approach to writing the environmental history of settler societies through an explicit focus on ecological processes, as distinct from the more commonly used landscape or geographic units. In this case, I focus upon the hydrological cycle and four key processes that constitute it. The processes are precipitation; flow above and below ground in rivers, creeks and aquifers; stored or still water in lakes, ponds and wetlands; and evaporation.
The work examines the impact of the ecological processes that make up the hydrological cycle within the context of the daily life of colonial settlers in the catchment of the Gippsland Lakes in south eastern Victoria, Australia, from the commencement of white colonization in the late 1830s up to the turn of the century. This time period was selected because by 1900, the principal changes which laid the foundation for the Lakes seriously compromised ecological health in the late 1980s and early 1990s were all in place.
Inspired by gestalt psychology, it examines the interaction of those processes with settler knowledge of biophysical processes, their religious and cultural beliefs, economic and political forces at work in their world, work and leisure time, their language and expressions, values and aspirations for themselves and their families. Each of these aspects informed their perceptions of the ecology around them, and particularly, their perception of the significance of water. The findings confirms the critical importance of cultural values, generated through myth, story and action, to understanding environmental changes. Colonial Gippslanders were committed to: a belief in progress, or alternately, banishing wilderness; a belief that the world was made by God for human benefit; and the desire for certainty versus the actual uncertainty in hydrological conditions.
Collectively, colonial Gippslanders believed in progress as much as they believed in God, believed themselves largely separate from nature and plumped for certainty. They set to re-plumbing the catchment to eliminate, as far as possible within their technical capabilities, the natural variations within the hydrological cycle. The tools which they applied to achieve this radical re{u00AD}plumbing included the application of engineering knowledge, supported by increasing amounts of technology and machinery and by sophisticated socio{u00AD}political lobbying.
