This project will investigate how and when the atmosphere became oxygen-rich by analyzing ancient barrier reefs and other rocks that formed between 1000 to 300 million years ago, spanning the appearance and diversification of animals and plants. The project is significant because the buildup of oxygen in the atmosphere was arguably the most important chemical process ever to have occurred on Earth and controlled the evolution of environments, climate and life. A major outcome will be an improved understanding of how the Earth's atmosphere and climate are regulated by geological processes. This project will generate new knowledge about how sedimentary zinc, lead and copper ore deposits form, which may guide exploration for these commodities.Read moreRead less

Summary
The oxygenation of Earth’s early marine ecosystems. This project aims to map out the complex evolution of the Earth’s ocean ecosystems and oxygenation using marine carbonates. The oxygenation of Earth’s surface is one of the most profound processes to shape the planet, affecting all biological and geological systems. However, uncertainties remain in the timing of oxygenation and how it relates to the evolution of life. This project will develop our understanding of how Earth has remained habitab ....The oxygenation of Earth’s early marine ecosystems. This project aims to map out the complex evolution of the Earth’s ocean ecosystems and oxygenation using marine carbonates. The oxygenation of Earth’s surface is one of the most profound processes to shape the planet, affecting all biological and geological systems. However, uncertainties remain in the timing of oxygenation and how it relates to the evolution of life. This project will develop our understanding of how Earth has remained habitable through significant intervals of environmental change. Using the geology of Australia, and elsewhere, this project is expected to derive the oxygenation evolution of ancient seawater and its effect on reef ecosystems during critical intervals of Earth’s history.Read moreRead less
Computational modelling of nanofluids for industrial applications. The use of nanoparticles in heat transfer fluids, then known as nanofluids, increases their specific heat and thermal conductivity. Recent experimental works highlight that anomalous transport phenomena are evident in nanofluids that cannot be adequately described by classical conservation laws. We will extend these conservation laws to incorporate fractional operators to capture the fluid memory effects and the impact of particl ....Computational modelling of nanofluids for industrial applications. The use of nanoparticles in heat transfer fluids, then known as nanofluids, increases their specific heat and thermal conductivity. Recent experimental works highlight that anomalous transport phenomena are evident in nanofluids that cannot be adequately described by classical conservation laws. We will extend these conservation laws to incorporate fractional operators to capture the fluid memory effects and the impact of particle clustering. Computational modelling and experimental investigations will be undertaken to identify the heat transfer mechanisms of various nanofluids. The outcomes of the work will increase knowledge on nanofluids and offer a significant opportunity to improve the efficiency of many thermal engineering systems.Read moreRead less

Management of gas and water resources is of significant importance to the Australian economy and society. Industry and government use digital modelling to assist in resources management. The first step in modelling is to correlate geological data and then use geostatistics to estimate properties in areas without data. This project aims to produce a new geological framework for the Surat Basin underpinned by new zircon ages and ages of fossils in sediments and a new geostatistical methodology to better represent flow properties in coal seams and aquifers. This is expected result in a more accurate modelling methodology that can be used by industry and government for modelling resources, including in other basins in Australia and worldwide.Read moreRead less
Sustainable fiscal federalism and reform of the GST distribution system. The primary source of funds for Australian States and Territories is GST revenue distributed by the Commonwealth using an equalisation formula that has proved to be politically unsustainable and in recent times manifestly inadequate to provide the revenue needed in response to crises and natural disasters.

The primary source of funds for Australian States and Territories is GST revenue distributed by the Commonwealth using an equalisation formula that has proved to be politically unsustainable and in recent times manifestly inadequate to provide the revenue needed in response to crises and natural disasters. A tipping point has been reached and reform is urgently needed. Drawing on international experience with GST distributions specifically and fiscal federalism more generally, the project aims to develop a reform blueprint for a sustainable and equitable fiscal federalism regime in Australia that best aligns with Australia’s current and long-term fiscal needs.Read moreRead less
