Ecological-epidemiological models of feral swamp buffalo control in northern Australia. This research is locally, nationally and internationally significant because it 1) improves the capacity of the Northern Territory and its traditional aboriginal owners to manage together this prevalent species in an effort to minimise disturbance to native flora and fauna and to understand the long-term implications of continued proliferation, 2) provides a nationally relevant system to monitor and project t ....Ecological-epidemiological models of feral swamp buffalo control in northern Australia. This research is locally, nationally and internationally significant because it 1) improves the capacity of the Northern Territory and its traditional aboriginal owners to manage together this prevalent species in an effort to minimise disturbance to native flora and fauna and to understand the long-term implications of continued proliferation, 2) provides a nationally relevant system to monitor and project the spread of disease through feral animal populations in Australia, and 3) combines quantitative data and robust analytical tools that can be used as a template for solving many broad-scale feral animal problems around the world.Read moreRead less
Surviving in a toad-colonised landscape: manipulating predator behaviour to reduce the impact of the cane toad invasion. Invasive species pose a major threat to biodiversity; and within Australia, cane toads are widely viewed as one of the biggest such problems. Vigorous attempts at toad control have failed to slow the invasion front, and toads are now entering the Kimberley region. If we can’t stop the toads, are there other ways to reduce the numbers of native predators killed by eating thes ....Surviving in a toad-colonised landscape: manipulating predator behaviour to reduce the impact of the cane toad invasion. Invasive species pose a major threat to biodiversity; and within Australia, cane toads are widely viewed as one of the biggest such problems. Vigorous attempts at toad control have failed to slow the invasion front, and toads are now entering the Kimberley region. If we can’t stop the toads, are there other ways to reduce the numbers of native predators killed by eating these poisonous invaders? Predators given nausea-inducing chemicals with their first toad meal rapidly learn to avoid cane toads as prey, enabling them to survive even where toads are present. The study will develop those methods for several vulnerable native species, including techniques for deployment of aversion-inducing baits in advance of the toad invasion.Read moreRead less
Tectonic geography of the world's oldest petroleum play, the McArthur Basin. This projects aims to develop a 4D tectonic geography framework to support the effective exploration of the McArthur Basin. This project will construct this by a) investigating the evolving tectonic setting, b) examining intra-basin correlations and trace the source to sink sediment provenance, c) unraveling the depositional geography using novel isotopic proxies, and, d) constructing the subsequent thermal history of ....Tectonic geography of the world's oldest petroleum play, the McArthur Basin. This projects aims to develop a 4D tectonic geography framework to support the effective exploration of the McArthur Basin. This project will construct this by a) investigating the evolving tectonic setting, b) examining intra-basin correlations and trace the source to sink sediment provenance, c) unraveling the depositional geography using novel isotopic proxies, and, d) constructing the subsequent thermal history of the basin. The techniques developed through this project will de-risk the exploration for petroleum in this basin, and be applicable in opening up Proterozoic petroleum elsewhere in Australia and internationally.Read moreRead less
A multispecies approach to managing feral animals in tropical savanna landscapes. Controlling invasive species is important for maintaining healthy landscapes. Often, multiple invasive species occupy a landscape and simultaneous management of them is required. Our innovative management tool will allow land managers to develop and implement control strategies for environmentally invasive species in Northern Australia and globally.
Cane toads in southern Australia: invasion dynamics and options for control. This project aims to investigate the spread of cane toads through southern Australia, an invasion front that has attracted far less research than the same species’ expansion through tropical regions, even though toads severely impact native wildlife in both areas. This project expects to generate new knowledge to determine why the rate of toad invasion is so much slower in New South Wales than in the tropics, and how be ....Cane toads in southern Australia: invasion dynamics and options for control. This project aims to investigate the spread of cane toads through southern Australia, an invasion front that has attracted far less research than the same species’ expansion through tropical regions, even though toads severely impact native wildlife in both areas. This project expects to generate new knowledge to determine why the rate of toad invasion is so much slower in New South Wales than in the tropics, and how best to modify newly-developed approaches to toad control to the conditions in southern Australia. Expected outcomes include predicting future trajectories of expansion, and identifying optimal approaches to toad control and impact mitigation. This should provide significant benefits for biodiversity conservation.Read moreRead less
Estimating the potential supply of environmental services by landholders. Wilderness, natural habitats, biodiversity and other aspects of natural capital and their associated ecosystem services are in decline. Increasing scarcity is driving a surge in interest in these services and their value. It potentially provides opportunities for landholders to be generating income from environmental services provision, and lessens dependency on livestock, crop and fibre production. But how realistic are t ....Estimating the potential supply of environmental services by landholders. Wilderness, natural habitats, biodiversity and other aspects of natural capital and their associated ecosystem services are in decline. Increasing scarcity is driving a surge in interest in these services and their value. It potentially provides opportunities for landholders to be generating income from environmental services provision, and lessens dependency on livestock, crop and fibre production. But how realistic are these prospects? A critical aspect of potential markets for environmental services is their supply. This project examines the supply side of environmental services by exploring determinants of ability and willingness of landholders to provide these services.Read moreRead less
Novel isotope techniques to explore the Centralian Superbasin, Australia. This project will leverage new advances in analytical instrumentation and isotope techniques to generate improved geochronological and stratigraphic framework for the Centralian Superbasin, a vast ancient depositional system covering much of central Australia.

This project will leverage new advances in analytical instrumentation and isotope techniques to generate improved geochronological and stratigraphic framework for the Centralian Superbasin, a vast ancient depositional system covering much of central Australia. The project aims to apply novel laser-based dating of sedimentary rocks, coupled with metal isotope proxy reconstructions of the basin’s palaeogeography, hydrological connectivity and past redox conditions, which are all critical parameters to guide and de-risk future exploration of sediment-hosted resources in this frontier basin. Anticipated outcomes will benefit Australia's resources economy, while providing insights into the evolution of Earth’s surface environment in deep time.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
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
