Will East Coast Lows change in frequency or intensity in the future? East Coast Lows, the largest storms on the south-east coast of Australia, produce both large benefits and losses for this highly populated region of the country. An urgent national priority exists to understand the driving mechanisms for these events and to quantify how the frequency and intensity of these systems will change due to climate change.
Is restoration working? An ecological genetic assessment. This project aims to assess the success of restoration in terms of ecological and genetic viability for plant species in the Fitzgerald River–Stirling Range region of Western Australia, where significant investment is being made in restoring connectivity at a landscape scale. The project intends to compare reproductive output, pollinator behaviour, mating, genetic diversity and pollen dispersal in restored sites with those of undisturbed ....Is restoration working? An ecological genetic assessment. This project aims to assess the success of restoration in terms of ecological and genetic viability for plant species in the Fitzgerald River–Stirling Range region of Western Australia, where significant investment is being made in restoring connectivity at a landscape scale. The project intends to compare reproductive output, pollinator behaviour, mating, genetic diversity and pollen dispersal in restored sites with those of undisturbed natural vegetation. The project moves measures of restoration success beyond that of population establishment and survival to incorporate the evolutionary processes that provide long-term resilience, persistence and functional integration of restored populations into broader landscapes.Read moreRead less
Removal of Perfluorinated Chemicals Using New Fluorinated Polymer Sorbents. Per- and polyfluoroalkyl substances (PFAS) are a family of highly persistent chemicals that are linked to a number of human diseases, however existing approaches for removal of PFAS are highly inefficient. This project aims to develop and evaluate novel, reusable polymer sorbents for effective PFAS removal. The polymer sorbents will enable efficient, selective and continuous sorption of PFAS, while maintaining excellent ....Removal of Perfluorinated Chemicals Using New Fluorinated Polymer Sorbents. Per- and polyfluoroalkyl substances (PFAS) are a family of highly persistent chemicals that are linked to a number of human diseases, however existing approaches for removal of PFAS are highly inefficient. This project aims to develop and evaluate novel, reusable polymer sorbents for effective PFAS removal. The polymer sorbents will enable efficient, selective and continuous sorption of PFAS, while maintaining excellent environmental stability for long-term implementation in practical devices. The project will develop novel polymer sorbents to revolutionize the remediation of PFAS with high technical, economic and environmental feasibility, creating a pathway to a PFAS-free world, and ultimately protecting the natural environment.Read moreRead less

The aim of this project is to develop and demonstrate high-performance devices for ammonia production from renewables by a scalable electrolysis method. This will be achieved by experimental and modelling investigations of the nitrogen reduction reaction to guide the design of tailor-made cathodes. New knowledge in catalysis and materials science is expected to be generated. The target outcome of the project is a sustainable and affordable ammonia synthesis method as an alternative to the current fossil-fuels-based and excessively greenhouse-emitting process. The technology to be developed in this project is anticipated to be of significant benefit to the Australian agriculture sector as a local, on-demand source of low-cost fertilisers.Read moreRead less
Understanding extreme wind gusts and associated risks in NSW. Wind gusts are rare bursts of high wind, often associated with thunderstorm outflows. They can do significant structural damage, and their rarity and small scale make prediction and risk assessment difficult. This proposal seeks to better understand and predict wind gusts and their impacts to aid in planning. The project aims to use past observations, modelling, and basic theory to show what conditions lead to wind gusts and how like ....Understanding extreme wind gusts and associated risks in NSW. Wind gusts are rare bursts of high wind, often associated with thunderstorm outflows. They can do significant structural damage, and their rarity and small scale make prediction and risk assessment difficult. This proposal seeks to better understand and predict wind gusts and their impacts to aid in planning. The project aims to use past observations, modelling, and basic theory to show what conditions lead to wind gusts and how likely they are to exceed key thresholds. It targets important scientific and practical issues such as the joint occurrence of gusts and high rainfall, role of gusts in contributing to dust and other airborne pollutants, impacts of gusts on subsequent storm activity, and gusts in a warming climate.Read moreRead less
Precipitation in wintertime storms across southeast Australia, Tasmania and the Southern Ocean. The pristine conditions and strong wind-shear over the Southern Ocean affect the formation of precipitation in clouds over the region, which is vital to the water supply of southeastern Australia and Tasmania. This project will evaluate and improve the ability to simulate this precipitation, which will lead to better water resource management.
Improved Indigenous population projections for policy and planning. This project will use a range of methods to understand the population dynamics of the Australian Aboriginal and Torres Strait Islander (Indigenous) population. This information will allow policy makers to plan and target resources and help Indigenous organisations understand what is happening to the population in their communities.
Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and sourc ....Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and source of stocked versus wild fish determined in stocked and unstocked rivers. Natural chemical signatures will also help determine important recruitment areas. The outcomes will allow fisheries managers to make informed decisions regarding stocking strategies.Read moreRead less
Genetic Rescue of Australia's Arid Zone Plants. Many Australian arid zone plant species have been severely damaged by grazing, loss of pollinators and other impacts and cannot survive without urgent intervention. Some exist as small fragmented populations with too little genetic variation to reproduce or adapt to further environmental change. We propose to combine surveys of genetic (DNA) diversity and the reproductive status of populations in order to identify species that could be saved by a ....Genetic Rescue of Australia's Arid Zone Plants. Many Australian arid zone plant species have been severely damaged by grazing, loss of pollinators and other impacts and cannot survive without urgent intervention. Some exist as small fragmented populations with too little genetic variation to reproduce or adapt to further environmental change. We propose to combine surveys of genetic (DNA) diversity and the reproductive status of populations in order to identify species that could be saved by a process of ‘genetic rescue’. Genetic rescue will involve experimental pollinations to produce highly fit seedlings and later transplanting of these seedlings to augment genetically deficient populations.
