Space gravity: squeezing the last drop of hydrological information out of current and future missions. Australia needs space gravity measurements in order to estimate regional-scale total water storage changes on our continent. This project will deliver the analysis capability required to exploit all the measurements of the current Gravity Recovery and Climate Experiment (GRACE) mission and to place Australia in a state of readiness for the 2017 GRACE Follow On mission.
The Governance of Defiance. Defiance is a threat to social order. For this reason sanctioning institutions are in place to punish the defiant through legal, financial and sometimes physical means. The institutional rationale is that, at worst defiance will be silenced and at best, compliance will take its place. Increasingly, adverse and unexpected consequences of dealing with defiance in this way have been exposed. To be accountable for their actions, therefore, authorities have begun to develo ....The Governance of Defiance. Defiance is a threat to social order. For this reason sanctioning institutions are in place to punish the defiant through legal, financial and sometimes physical means. The institutional rationale is that, at worst defiance will be silenced and at best, compliance will take its place. Increasingly, adverse and unexpected consequences of dealing with defiance in this way have been exposed. To be accountable for their actions, therefore, authorities have begun to develop more responsive and deliberative systems. But they also need to know how to read defiance. When is defiance an inappropriate response to a more than reasonable request? And when is defiance a reflection of institutional failure? This project can inform such decision making.Read moreRead less
Interactions of physical processes for Southern Ocean dynamics. The Southern Ocean circulation is a major component of the earth’s climate system. Its behaviour depends strongly on the interactions of physical processes that are poorly understood and are not well represented in ocean models. This project will use laboratory experiments and fully-resolved flow simulations with appropriate scaling to examine the dynamics of key interactions between convection, mixing, wind-driven flow, eddies and ....Interactions of physical processes for Southern Ocean dynamics. The Southern Ocean circulation is a major component of the earth’s climate system. Its behaviour depends strongly on the interactions of physical processes that are poorly understood and are not well represented in ocean models. This project will use laboratory experiments and fully-resolved flow simulations with appropriate scaling to examine the dynamics of key interactions between convection, mixing, wind-driven flow, eddies and large-scale currents, while translating the results to improve ocean models. The project will develop the fundamental physics of the deep overturning circulation, the Antarctic Circumpolar Current, response timescales and heat uptake in a warming world, and improve predictions of oceanic and climate change.Read moreRead less
Melting and circulation in Antarctic ice shelf cavities. This project will explore and model the mechanisms causing the observed increased rate of melting of Antarctica’s ice shelves. This understanding is essential for accurate predictions of sea level rise and global thermohaline circulation over the next century, so that their impact on society can be planned for and mitigated.
A new energy budget for the global circulation of the oceans. The energy sources and sinks that govern the global circulation of the oceans will be re-evaluated, building a new picture of the energy budget of the oceans. This will lead to new knowledge of the circulation of the deep oceans, to better ocean and climate-prediction models, and ultimately to more reliable estimates of future climate change.
Optimal taxation when the allocation of time matters. This project aims to incorporate evidence-based models of time allocation, which go beyond the simple division between work and leisure, in optimal tax settings. This approach will help to inform the public policy debate on child support, by questioning whether, and if so how, to subsidise childcare, where parental time use plays a crucial role.
Economic Inequality: Trends, Causes and Consequences. Measuring inequality and understanding its determinants is important for three reasons. First, knowing the causes and consequences of inequality is critical to making trade-offs between equity and efficiency. Second, the degree of economic mobility over the lifecycle determines how much opportunity people have to move upwards, and how much risk they face on moving downwards. This informs policies that guard against risk (eg. social insurance) ....Economic Inequality: Trends, Causes and Consequences. Measuring inequality and understanding its determinants is important for three reasons. First, knowing the causes and consequences of inequality is critical to making trade-offs between equity and efficiency. Second, the degree of economic mobility over the lifecycle determines how much opportunity people have to move upwards, and how much risk they face on moving downwards. This informs policies that guard against risk (eg. social insurance) and those that encourage risk (eg. entrepreneurship). Third, by learning more about intergenerational mobility, we can improve policies that seek to boost the life chances of children in disadvantaged households. Read moreRead less
Effectiveness of tax base erosion and profit shifting countermeasures effective. This project aims to evaluate the effectiveness of measures to combat tax avoidance by multinational enterprises. Estimates suggest that tax base erosion and profit shifting threaten up to 10 per cent of Australia’s corporate tax revenues. This project intends to establish benchmark indicators based on financial and tax data for Australian and foreign-owned companies, and test them on proposed policy changes up to 2 ....Effectiveness of tax base erosion and profit shifting countermeasures effective. This project aims to evaluate the effectiveness of measures to combat tax avoidance by multinational enterprises. Estimates suggest that tax base erosion and profit shifting threaten up to 10 per cent of Australia’s corporate tax revenues. This project intends to establish benchmark indicators based on financial and tax data for Australian and foreign-owned companies, and test them on proposed policy changes up to 2018. The project aims to expand knowledge of tax behaviour of multinational firms while providing timely and critical information for policy makers on whether measures actually improve the integrity of corporate tax.Read moreRead less
Examining the vulnerability of ocean carbon biogeochemistry in a high CO2 world. Rising CO2 levels in the atmosphere from human activity is changing the biogeochemistry of the ocean, with large potential consequences on future atmospheric CO2. This work will explore these changes and will result in a more complete understanding of how the ocean will either accelerate or delay the increase in atmospheric CO2.
Novel water treatment processes. The objective of this project is the discovery of novel methods for the treatment and reuse of water for both industrial and household applications. Improved treatment systems with the potential for water reuse offer significant improvements to our overall water management potential.

The objective of this project is the discovery of novel methods for the treatment and reuse of water for both industrial and household applications. Improved treatment systems with the potential for water reuse offer significant improvements to our overall water management potential. The first part of the project is designed to focus on the study of hot bubble column evaporators for solute decomposition, sterilisation and the de-watering of heavily contaminated industrial wastewater. The second part would be based on the study of a suitable depth filter medium for the treatment of partially treated household sewage water. This is designed to form part of an on-site household sewage water treatment and reuse system which is currently being developed.Read moreRead less
