Sediment-derived scenarios of wetland status and change, the Lower River Murray, SA. River Murray wetlands changed early in European settlement so the pre-impact conditions are invisible to managers relying on anecdote or monitoring. Baseline conditions of wetlands can be derived from ecological archives preserved in sediments. Fossil diatom assemblages, reflective of past water quality, and other fossils, will be exhumed from sediment sequences to reconstruct wetland conditions. The integration ....Sediment-derived scenarios of wetland status and change, the Lower River Murray, SA. River Murray wetlands changed early in European settlement so the pre-impact conditions are invisible to managers relying on anecdote or monitoring. Baseline conditions of wetlands can be derived from ecological archives preserved in sediments. Fossil diatom assemblages, reflective of past water quality, and other fossils, will be exhumed from sediment sequences to reconstruct wetland conditions. The integration of multiple indicators of the past will generate graphic re-enactments of natural wetland dynamics. These will provide a vision for community and government on-ground managers enabling them to perceive appropriate targets for wetland state and so generate measures to work towards sustainable conditions.Read moreRead less
Retrospective ecological character assessment for a review of Ramsar status of The Coorong, SA. Integrated analyses of the chemical and biological remains contained in the sediments of the Coorong will provide for a reconstruction of ecological change and variability over the last several thousand years. Detailed analyses of the recent sediments will measure how the condition of the Coorong has departed from this natural background and so provide an audit of human impact on the last wetland in t ....Retrospective ecological character assessment for a review of Ramsar status of The Coorong, SA. Integrated analyses of the chemical and biological remains contained in the sediments of the Coorong will provide for a reconstruction of ecological change and variability over the last several thousand years. Detailed analyses of the recent sediments will measure how the condition of the Coorong has departed from this natural background and so provide an audit of human impact on the last wetland in the Murray darling Basin. This evidence will directly inform the determination of the ecological character of this Ramsar listed, national ecological asset and steer its management for a sustainable future. Read moreRead less
The history of North Stradbroke Island's wetlands: defining natural climate variability in south-east Queensland and improving ecosystem management. South-east Queensland has among the fastest growing populations in Australia. It has also experienced severe drought lasting more than a decade. These combined pressures have led to the expenditure of more than $9 Billion on water resource development. However, it is not known whether the current drought is part of a natural cycle (or, importantly, ....The history of North Stradbroke Island's wetlands: defining natural climate variability in south-east Queensland and improving ecosystem management. South-east Queensland has among the fastest growing populations in Australia. It has also experienced severe drought lasting more than a decade. These combined pressures have led to the expenditure of more than $9 Billion on water resource development. However, it is not known whether the current drought is part of a natural cycle (or, importantly, if it represents the worst extremes in such a cycle). We will determine whether this is the case and, in doing so, contribute to national and international debates about the role of human-induced vs natural climate change.Read moreRead less
The effective treatment of drug using offenders: the impact of treatment modality, coercion and treatment readiness on criminal recidivism. Drug use is associated with significant health, social, and economic costs. Given the established drug-crime connection and the high rate of relapse among drug-using offenders, the outcomes of this research will assist policymakers in identifying clinically and cost effective approaches to service delivery. Moreover, in view of the debate that surrounds the ....The effective treatment of drug using offenders: the impact of treatment modality, coercion and treatment readiness on criminal recidivism. Drug use is associated with significant health, social, and economic costs. Given the established drug-crime connection and the high rate of relapse among drug-using offenders, the outcomes of this research will assist policymakers in identifying clinically and cost effective approaches to service delivery. Moreover, in view of the debate that surrounds the efficacy of coerced treatment, and the extent to which Australia should follow the United States of America’s lead of mandating treatment for all substance using offenders, the project will test the proposition that compulsory treatment has positive outcomes in terms of reductions in recidivism.Read moreRead less
Heavy metal phytotoxicity in long-term contaminated soils: Implications for the development of Australian regulatory guidelines and realistic environmental risk assessment. Heavy metal contamination is a serious global environmental problem. There are >80,000 potentially contaminated sites in Australia alone with many of these sites in the urban environment and former mining areas. The current guidelines for phytotoxicity testing (National Environmental Protection Measure 1999) are based on tota ....Heavy metal phytotoxicity in long-term contaminated soils: Implications for the development of Australian regulatory guidelines and realistic environmental risk assessment. Heavy metal contamination is a serious global environmental problem. There are >80,000 potentially contaminated sites in Australia alone with many of these sites in the urban environment and former mining areas. The current guidelines for phytotoxicity testing (National Environmental Protection Measure 1999) are based on total metal concentrations that do not take into consideration of bioavailability and wide ranging Australian soil types. Serious concerns have been raised on the applicability of these guidelines and their protective limits in ecological risk assessment. This project aims at developing phytotoxicity guidelines applicable to a wide range of soil types common to Australia.Read moreRead less
Identifying cost-effective reforestation approaches for biodiversity conservation and carbon sequestration in the Australian wet tropics. There is great potential for rainforest reforestation to help in the protection of Australia's tropical flora and fauna. Little is known, however, about how to reforest pasture to rainforest for the purpose of maximising the recovery of native biodiversity. We propose a unique experimental study of rainforest reforestation practices with biodiversity conservat ....Identifying cost-effective reforestation approaches for biodiversity conservation and carbon sequestration in the Australian wet tropics. There is great potential for rainforest reforestation to help in the protection of Australia's tropical flora and fauna. Little is known, however, about how to reforest pasture to rainforest for the purpose of maximising the recovery of native biodiversity. We propose a unique experimental study of rainforest reforestation practices with biodiversity conservation as a primary goal. Reforestation is currently an unlikely option for most landholders in Australia's tropics given the lack of data on the economic benefits obtainable from such efforts. Our study examines the profits obtainable through the carbon market for each reforestation approach with the goal of increasing the feasibility of rainforest reforestation in North Queensland.Read moreRead less
A Future Beyond the Wall: Improving Post-release Employment Outcomes for People Leaving Prison. Engaging in meaningful work has been shown to reduce re-offending by ex-prisoners, but few prison releasees internationally or in Australia gain employment, and successful pathways to employment for this group are poorly researched and understood.

Engaging in meaningful work has been shown to reduce re-offending by ex-prisoners, but few prison releasees internationally or in Australia gain employment, and successful pathways to employment for this group are poorly researched and understood. This study aims to gather and analyse, for the first time, comparative data from Australian jurisdictions and employment agencies on the relationship between in-prison and post-prison vocational education and employment programs, employment and recidivism. It aims to identify effective elements, strategies, program and policy directions in offender training and employment. This is a unique partnership amongst key academics in the field, peak national bodies, correctional and employment organisations.Read moreRead less
Establishing genetic guidelines for the effective ecological restoration of seagrass meadows. Industry and coastal development in Australia are of national importance for economic growth and prosperity, but they threaten benthic habitats, like seagrasses. Loss of seagrass meadows without mitigation results in greater coastal impacts from damaging storms and waves and a reduction in the health and productivity of marine environments globally. Thus the ecological restoration of seagrass meadows is ....Establishing genetic guidelines for the effective ecological restoration of seagrass meadows. Industry and coastal development in Australia are of national importance for economic growth and prosperity, but they threaten benthic habitats, like seagrasses. Loss of seagrass meadows without mitigation results in greater coastal impacts from damaging storms and waves and a reduction in the health and productivity of marine environments globally. Thus the ecological restoration of seagrass meadows is an urgent national priority action that involves industry, government and the community. Through the detailed assessment of population genetic variation and key population processes in seagrasses, this project will establish genetic guidelines for a more effective seagrass restoration industry.Read moreRead less
