This project aims to provide critical new information on the archaeology and natural history of one of the world’s largest unregulated desert river systems. Mithaka country incorporates the highly significant Channel Country on the eastern edge of Australia's arid centre. Preliminary research has identified more than 70 large site complexes that provide critical insights on how the Mithaka people adapted to this unique environment and took part in Australia's most extensive long distance trade systems. The project will study the archaeological landscape, artefacts and an extensive in-situ skeletal record in the context of a detailed palaeoenvironmental study. It will provide a new cultural-environmental history of this landscape and provide the Mithaka with multiple strands of connection to their ancestral land and culture and support their aspirations to create employment through rangers programs, education and cultural tourism.Read moreRead less
What is 'natural'?: Locating and deciphering pre-human records of vegetation from northern Australian savannahs. The nature and magnitude of the environmental impact of human colonisation of Australia are fundamental issues in Australian prehistory and ecology. The project will locate and develop archives of environmental change from sinkholes in the Northern Territory that date back to the Last interglacial - a period which had a similar climate to the present day, but was before humans arrived ....What is 'natural'?: Locating and deciphering pre-human records of vegetation from northern Australian savannahs.

The primary aim of this project is to systematically construct a high-resolution record of landscape and vegetation change within the Willandra Lakes Region World Heritage Area over the past 50,000 years. Using state-of-the-art dating techniques and a multidisciplinary approach, this project will provide critical environmental context for the region's world-famous archaeological record, charting the environmental changes that occurred as NSW's largest inland lake system ran dry at ~15,000 years ago. Anticipated outcomes include a refined understanding of: the drivers, timing, and periodicity of lake desiccation; the influence these changes had on regions landforms and vegetation; and how this impacted the lives of people living here.

Investigating the archaeology of human settlement in the highlands of PNG. Around 50 000 years ago, people crossed the Wallace Line and set foot on Sahul (Pleistocene Australia-New Guinea) for the first time. Rapid dispersal across the Sahul continent followed during a period of climatic deterioration. Subsequent human impacts on the landscape are well preserved in the fossil record, particularly plants. This project aims to implement an archaeological and palaeobotanical approach to investigate ....Investigating the archaeology of human settlement in the highlands of PNG. Around 50 000 years ago, people crossed the Wallace Line and set foot on Sahul (Pleistocene Australia-New Guinea) for the first time. Rapid dispersal across the Sahul continent followed during a period of climatic deterioration. Subsequent human impacts on the landscape are well preserved in the fossil record, particularly plants. This project aims to implement an archaeological and palaeobotanical approach to investigate the temporal and spatial patterning of landscape use through a period of climatic change in the Late Quaternary. The results are expected to provide a fuller understanding of the subsistence strategies and dynamics of human responses to climate change over long time periods.Read moreRead less
Long range toxic metal pollution in Australia and the Southern Ocean. This project aims to investigate how environmental change and human activities since industrialisation have impacted toxic metal transport and deposition on the south coast of Australia, Tasmania and Southern Ocean islands. This project expects to fill gaps in understanding of the global mercury cycle using a state-of-the-art multidisciplinary methodology including the role of sea salt aerosols and hemispheric-scale wind patte ....Long range toxic metal pollution in Australia and the Southern Ocean. This project aims to investigate how environmental change and human activities since industrialisation have impacted toxic metal transport and deposition on the south coast of Australia, Tasmania and Southern Ocean islands. This project expects to fill gaps in understanding of the global mercury cycle using a state-of-the-art multidisciplinary methodology including the role of sea salt aerosols and hemispheric-scale wind patterns . Anticipated outcomes involve a novel palaeo-atmospheric model that can be applied in other parts of the world. This should provide significant benefits, such as science-based evidence to ratify the Minamata Convention on Mercury and guide new regulations to reduce environmental/health risks from metal pollution.

Summary
Investigating the synchroneity of global atmospheric shifts in the Holocene. The austral mid-latitude westerly winds dominate Southern Hemisphere climate variability today (including the Australasian region) and are tightly coupled to the Southern Ocean, modulating the air-sea CO2 flux. However, short instrumental records in the south make future climate projections uncertain. This Project will develop the first highly-detailed reconstructions of westerly airflow from targeted Southern Ocean isl ....Investigating the synchroneity of global atmospheric shifts in the Holocene. The austral mid-latitude westerly winds dominate Southern Hemisphere climate variability today (including the Australasian region) and are tightly coupled to the Southern Ocean, modulating the air-sea CO2 flux. However, short instrumental records in the south make future climate projections uncertain. This Project will develop the first highly-detailed reconstructions of westerly airflow from targeted Southern Ocean islands during key periods of change, representing a range of climate states over the Holocene (the last 11,650 yrs). Intensive radiocarbon dating will allow precise alignment to a network of palaeoclimate records to test the timing, drivers and impacts of circulation change across Australia and globally.Read moreRead less
Millennial climate change in southern Australia during the Last Glacial. Abrupt warming and cooling events were a persistent feature of Earth's most recent climate cycle. Surprisingly, little is known of how these events affected the climate of Australia. This project will produce precisely dated reconstructions of rainfall and temperature trends in southern Australia during these events. These new terrestrial and ocean data will be compared with model simulations to determine how rapidly abrupt ....Millennial climate change in southern Australia during the Last Glacial. Abrupt warming and cooling events were a persistent feature of Earth's most recent climate cycle. Surprisingly, little is known of how these events affected the climate of Australia. This project will produce precisely dated reconstructions of rainfall and temperature trends in southern Australia during these events. These new terrestrial and ocean data will be compared with model simulations to determine how rapidly abrupt climate perturbations in the Northern Hemisphere reached our region, and the processes by which this occurred. The results will advance theory on how abrupt climate change propagates globally and provide a long-awaited climatic context for capstone events in Australia's natural history.Read moreRead less
Next-generation luminescence dating techniques for Earth and archaeological science applications. Chronology is a critical component of geological and archaeological studies.

Chronology is a critical component of geological and archaeological studies. To reconstruct the evolutionary histories of Homo sapiens and other hominin species in their environmental context, we must establish reliable age estimates for key archaeological sites and Quaternary deposits. This project aims to develop new-generation sediment dating techniques using the non-fading infrared stimulated luminescence (IRSL) signal from potassium feldspars. These improved methods will be able to be applied to sites in Africa, Europe and Asia that contain important human fossils and artefacts, including the unique type localities of ‘Denisovans’ and ‘Hobbits’, to answer fundamental questions about the timing of key turning points in human evolution and dispersal.Read moreRead less
The dynamics of human environment interactions in late Pleistocene and Holocene highland New Guinea: a study of the Ivane valley. The project will investigate how access to starchy plant foods facilitated the movement of colonizing peoples into new environments, and was critical to survival in Sahul (Ice Age Australia/New Guinea). It will aid in understanding the dynamics of human responses to the impacts of climate change.
