The origins of human colonization in East Polynesia and their relevance to maritime migration. The Indo-Pacific is a world of islands, including Australia, which was colonized during prehistory in several phases of migration, the last and longest of which was in East Polynesia. Extensive excavation of a large, waterlogged archaeological site of this era in French Polynesia will provide a better understanding of the period, society and external relationships of the early migrants, and of the proc ....The origins of human colonization in East Polynesia and their relevance to maritime migration. The Indo-Pacific is a world of islands, including Australia, which was colonized during prehistory in several phases of migration, the last and longest of which was in East Polynesia. Extensive excavation of a large, waterlogged archaeological site of this era in French Polynesia will provide a better understanding of the period, society and external relationships of the early migrants, and of the processes of prehistoric maritime migration which link Australian peoples to those of our neighbours across the Pacific and Indian Oceans.Read moreRead less
Colonization of the Mariana Islands and its implications for Indo-Pacific prehistory. The Asia-Pacific region, including Australia, is linked by seas and oceans that have been crossed by colonists in ancient as well as recent times. The most significant prehistoric migration was the movement of people out of southern China, into Taiwan, Island Asia and from there into Micronesia and across the Pacific. New investigations of the oldest sites in the Marianas will provide better understanding of ea ....Colonization of the Mariana Islands and its implications for Indo-Pacific prehistory. The Asia-Pacific region, including Australia, is linked by seas and oceans that have been crossed by colonists in ancient as well as recent times. The most significant prehistoric migration was the movement of people out of southern China, into Taiwan, Island Asia and from there into Micronesia and across the Pacific. New investigations of the oldest sites in the Marianas will provide better understanding of early prehistoric maritime capacity, the connections between migrant groups who settled the islands of Asia and Oceania, and the processes of Indo-Pacific colonization. Improved knowledge of our neighbours capabilities and history is of clear national benefit to Australia.Read moreRead less
Crossing the Green Sea: maritime mobility, trans-oceanic interaction and remote island colonisation in the tropical Indian Ocean. Australia is an Indian Ocean nation.

Australia is an Indian Ocean nation. It is strategically and politically important to understand our Indian Ocean neighbours, including small island nations such as the Maldives and Seychelles. Researching their history is part of this process. Building a collaborative research capacity between Australian and other Indian Ocean scholars, publishing the results of research, building them into educational curricula, and maintaining a pool of Indian Ocean scholarly expertise in Australia is a national and community benefit. In addition, research results on the history of human colonisation and human impact on vulnerable environments will be significant to Australia as an island nation.Read moreRead less
The deep history of Sea Country: Climate, sea level and culture. This project aims to investigate the records of the now-submerged Pilbara coast (50,000 to 7000 years ago). Nearly a third of Australia’s landmass was drowned after the last ice age, and sea-level change displaced generations of people. Submerged landscape archaeology will help reveal past sea-level rise, population resilience, mobility and diet. The project integrates cultural and environmental studies and material analysis, and a ....The deep history of Sea Country: Climate, sea level and culture. This project aims to investigate the records of the now-submerged Pilbara coast (50,000 to 7000 years ago). Nearly a third of Australia’s landmass was drowned after the last ice age, and sea-level change displaced generations of people. Submerged landscape archaeology will help reveal past sea-level rise, population resilience, mobility and diet. The project integrates cultural and environmental studies and material analysis, and adapts a method from the world’s only confirmed submarine middens. It will use marine and aerial survey techniques to investigate physical and cultural submerged landscapes. This project expects to influence heritage and environmental management and the marine heritage sector.Read moreRead less
The Origin and Development of the Tongan Maritime Empire. This project aims to understand the nature and development of the Tongan maritime empire, the most complex socio-political entity to exist in prehistoric Oceania. Extensive excavations of monumental structures and other sites throughout the central Pacific will create the first cultural sequence of the empire and a comprehensive radiocarbon chronology.

This project aims to understand the nature and development of the Tongan maritime empire, the most complex socio-political entity to exist in prehistoric Oceania. Extensive excavations of monumental structures and other sites throughout the central Pacific will create the first cultural sequence of the empire and a comprehensive radiocarbon chronology. The excavations will concentrate on sites of cross-cultural contact between indigenous peoples of the region. In addition traditional and documentary historical records will be reanalysed. A substantial monograph will assess the significance of these new Pacific data in relation to our understanding of maritime empires around the world.Read moreRead less
Microanalysis of human fossils: new insights into age, diet and migration. Human occupation of Australia and the Pacific dates back tens of thousands of years. New micro-analytical techniques now make it possible to learn about the life histories of these ancient peoples: their diet, migration paths and the climate in which they lived.

Human occupation of Australia and the Pacific dates back tens of thousands of years. New micro-analytical techniques now make it possible to learn about the life histories of these ancient peoples: their diet, migration paths and the climate in which they lived. This project will benefit the Indigenous populations and researchers of neighbouring countries through collaboration and increased knowledge of their ancestors, thus enhancing Australia's links and status as a good neighbour in the region. This falls squarely into the Research Priority 'Safeguarding Australia - Understanding our Region and the World'. In the future, our analytical approach will give important insights into the complex and rich archaeological heritage of Australia. Read moreRead less
Integrated prediction of wave-induced liquefaction for stable breakwater heads. Breakwaters are central to the economies and lifestyles of many coastal areas around the world. The liquefaction of breakwater foundations causes the failure of breakwaters, with potentially deliterious consequences for life and property. The remedies involve large investments in maintenance and cause major disruptions to coastal activities. More accurate and reliable methods for analysing the stability of structures ....Integrated prediction of wave-induced liquefaction for stable breakwater heads. Breakwaters are central to the economies and lifestyles of many coastal areas around the world. The liquefaction of breakwater foundations causes the failure of breakwaters, with potentially deliterious consequences for life and property. The remedies involve large investments in maintenance and cause major disruptions to coastal activities. More accurate and reliable methods for analysing the stability of structures and their foundations is urgently required, and will bring major benefits to Australian coastal facilities. We will create the science to transform our understanding of the mechanisms of wave-induced liquefaction. This will enable engineers to significantly improve the stability and robustness of marine structures.Read moreRead less
Poro-elastic, single domain model of wave-induced transport and transformation of pollutants in coastal sediments. The sediments in many bays and estuaries in Australia are contaminated by pollutants due to discharge of waste from the river, groundwater or/and ocean outfall. Most previous research has had a multi-domain approach and have ignored the wave-dirven advective flow and effects of soil behaviour in coastal sediment. In this study, we will couple the procedure of pollutant transport ne ....Poro-elastic, single domain model of wave-induced transport and transformation of pollutants in coastal sediments. The sediments in many bays and estuaries in Australia are contaminated by pollutants due to discharge of waste from the river, groundwater or/and ocean outfall. Most previous research has had a multi-domain approach and have ignored the wave-dirven advective flow and effects of soil behaviour in coastal sediment. In this study, we will couple the procedure of pollutant transport near the sediment-water interface by a single domain approach, and link wave-dirven advective flow and contaminant in marine sediments. The research outcomes will provide a better prediction of the transformation behaviour of pollutants in contaminated sediments.Read moreRead less
Coupling models for ocean waves, groundwater and porous seabeds interaction. The ocean waves, groundwater flow and porous seabeds interaction problem is vital for erosion control, saltily and biological activities in coastal regions. Most previous research has investigated the problem from individual aspects, rather than a coupling concept. In this study, we will develop advanced theoretical models for procedures of waves propagation, water table fluctuations and soil behaviour in a porous seabe ....Coupling models for ocean waves, groundwater and porous seabeds interaction. The ocean waves, groundwater flow and porous seabeds interaction problem is vital for erosion control, saltily and biological activities in coastal regions. Most previous research has investigated the problem from individual aspects, rather than a coupling concept. In this study, we will develop advanced theoretical models for procedures of waves propagation, water table fluctuations and soil behaviour in a porous seabed, and couple them in a model. A series of experiments will be conducted for the verification of the theoretical findings. The research outcomes will provide a better understanding of the interaction between ocean wave, groundwater flow and porous seabeds.Read moreRead less
Bed shear stress on beach sediment and coastal structures under wave run-up. The aim of this work is to obtain critical new information about the way waves interact with the coast and the damage they can cause to beaches and coastal protection structures. This new data will provide the basis for improved predictions of coastal erosion and better coastal engineering design in the face of sea-level rise and climate change.
