Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniques will be used to elucidate the fundamental mechanisms of gravity current entrainment and propagation. This knowledge will set a strong foundation to improve operational forecasts of smoke transport that will allow government agencies to better respond to the negative impact of these complicated flows.Read moreRead less
Multi-Country Study on Health Effects of Bushfire Air Pollution. Catastrophic bushfires are a major natural disaster, causing serious air pollution.

Catastrophic bushfires are a major natural disaster, causing serious air pollution. However, aligning bushfire air pollution and public health policies becomes a significant challenge, because limited studies are available on relationships between bushfire air pollution and human health, particularly for the prolonged exposure. We will characterize the nature of the relationships between bushfire air pollution and mortality/morbidity by developing a multi-country study; and estimate the burden of diseases attributed to bushfire air pollution. This project will provide essential scientific evidence to policy-makers and stakeholders in the development, prioritization and implementation of health protection strategies and policies.

This project aims to critically evaluate the regulation of conscientious objection to abortion. A range of state-based laws regulate this practice in Australia, and there is evidence that all result in inequitable access, harms to women and lack clarity for providers. The project will critically evaluate the legal and regulatory options for managing conscientious objection and interview conscientious objectors to develop a conceptual model to explain their practices. A participatory process with experts will identify the optimal model for regulation and how to translate the model to practice. Expected outcomes are world first evidence on practice, progress towards effective regulation, and benefits will be reduced conflict and harms.Read moreRead less
