The project aims to identify naturally occurring micro-organisms to increase the effectiveness of Green Guard ®, which is a biopesticide used against the Australian plague locust. The project will use next-generation sequencing and other molecular techniques to potentially identify candidate microbes or combinations of microbes that can be added to Green Guard to enhance locust susceptibility. The project also aims to quantify the interactive impact of temperature and nutrition on immune function, disease resistance and host-plant quality of plague locusts; and to explore the combined effects of temperature, habitat and Green Guard, in combination with candidate microbes or pathogens, on the behaviour and collective movement of locusts. It is anticipated that this will have implications for management and control strategies.Read moreRead less

This project aims to deliver fundamental knowledge by integrating the modelling and control with the design of next generation hypersonic platforms. In an era where Australia's national security reliance on geographic isolation and support from allied forces are being challenged, the research outcomes of this project will play an important role in understanding the capabilities of hypersonic systems. The project will also have significant spillover benefits into other complex system domains, where computational tools can be used to aid in design leading to high embedded-IP products for Australian industry. Furthermore, the proposal encompasses a strong research training aspect, with graduates exposed to leading edge industry and academia.Read moreRead less
Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si a ....Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.Read moreRead less
A landscape-scale experimental test of factors driving mammal declines in northern Australia. Australia has suffered the highest rate of modern mammal extinctions in the world. Foxes have been largely responsible for this extinction in southern Australia and probably also Central Australia. However the decline in mammals in northern Australia has occurred later than that in the south, and in the absence of foxes. We will adopt an experimental approach to determine the mechanisms driving mammal d ....A landscape-scale experimental test of factors driving mammal declines in northern Australia. Australia has suffered the highest rate of modern mammal extinctions in the world. Foxes have been largely responsible for this extinction in southern Australia and probably also Central Australia. However the decline in mammals in northern Australia has occurred later than that in the south, and in the absence of foxes. We will adopt an experimental approach to determine the mechanisms driving mammal declines and extinctions in northern Australia. Populations of brush-tail tree rats (Conilurus penicillatus) will be translocated to suitable habitat on mainland sites that experience different fire regimes and predation pressures.Read moreRead less
Controlling coastlines while generating power. The Project aims to produce strategies for protecting coasts from storms using farms of wave-energy machines, which also generate electricity. Increasing lengths of coast need protection as the climate changes, but conventional barriers create permanent environmental impacts and are a sunk cost usually borne by the taxpayer. The Project expects to derive a strategy for the setting of each machine in the farm, so that they collectively absorb or refl ....Controlling coastlines while generating power. The Project aims to produce strategies for protecting coasts from storms using farms of wave-energy machines, which also generate electricity. Increasing lengths of coast need protection as the climate changes, but conventional barriers create permanent environmental impacts and are a sunk cost usually borne by the taxpayer. The Project expects to derive a strategy for the setting of each machine in the farm, so that they collectively absorb or reflect damaging waves under severe conditions. Under normal conditions, enough wave energy to sustain environmental processes would pass through. Sales of electricity would help to pay back the capital cost. Outcomes would include reduced coastal-erosion costs and a low-intermittency energy supply.Read moreRead less
An integrated tool for informing pest management: modelling range shifts for an invasive vertebrate in response to climate change. Invasive species and climate contribute directly to loss of biodiversity and economic productivity. This research project focuses on providing user-orientated tools that enable a strategic approach to European rabbit management and vertebrate pest control in Australia in response to anticipated climate and land-use change.
Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia ....Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia from invasive diseases. There is an urgency to undertake our research because global environmental change and increasing movements of people (particularly military personnel) from overseas regions where these diseases are endemic is increasing the vulnerability of northern Australia to the (re)establishment of mosquito borne diseases.Read moreRead less
The effect of aerial spraying of two pesticides on semi-arid grasslands. The project will investigate how two pesticides, fipronil and metarrhizium, used to control locusts, affect semi-arid ecosystems by examining impacts on invertebrates, their predators, lizards and soil processes. The effects will be followed through time in a large scale experiment to determine recovery and compare each pesticide.
Conservation biology of the largest Australian freshwater tortoise, the broad-shelled tortoise, Chelodina expansa - rare and endangered or cryptic and secure? The Murray is a highly managed river, with flows controlled by catchments and diversions. The combined impacts of water resource development, habitat modification and introduced species are astonishingly diverse, and include extinctions of some fish and invertebrates and depression of populations of many other species. Australia's largest ....Conservation biology of the largest Australian freshwater tortoise, the broad-shelled tortoise, Chelodina expansa - rare and endangered or cryptic and secure? The Murray is a highly managed river, with flows controlled by catchments and diversions. The combined impacts of water resource development, habitat modification and introduced species are astonishingly diverse, and include extinctions of some fish and invertebrates and depression of populations of many other species. Australia's largest chelid turtle, the broad-shelled turtle, is a high-level consumer thought to be particularly sensitive to these changes. We will use an innovative combination of non-destructive technologies to investigate the conservation biology of this species in the Lower Murray, where it is regarded as rare and where its biology is virtually unknown to inform conservation management and restoration initiativesRead moreRead less
Development of a vaccine to protect koalas against koala retrovirus (KoRV). This project aims to develop a vaccine against koala retrovirus (KoRV) to arrest the increasing loss of animals due to this infection. Along with Chlamydia, KoRV threatens the long-term survival of the koala. KoRV infects over 95 per cent of Australia’s koalas and has been strongly linked to lymphoma and leukemia. Although quarantine and antiretroviral drug treatment are possible control measures, they are impractical in ....Development of a vaccine to protect koalas against koala retrovirus (KoRV). This project aims to develop a vaccine against koala retrovirus (KoRV) to arrest the increasing loss of animals due to this infection. Along with Chlamydia, KoRV threatens the long-term survival of the koala. KoRV infects over 95 per cent of Australia’s koalas and has been strongly linked to lymphoma and leukemia. Although quarantine and antiretroviral drug treatment are possible control measures, they are impractical in the wild, leaving vaccination as the only realistic option. This is valuable for both wild and captive koalas; zoos report high animal losses due to KoRV-associated lymphoma. The main outcome will be a KoRV vaccine which can be combined with a Chlamydia vaccine which is being developed in parallel.Read moreRead less
