Research outcomes from this new facility will empower government bodies, resource industries, and indigenous stakeholders with key baseline information to ensure the sustainable and sensitive development of west Australia's unique coastal and offshore regions, across heavily populated and pristine environments. This includes projecting future impacts on local industries (eg. energy, fisheries, tourism), rising shorelines with critical implications for existing and developing communities, and enhancing the resilience of habitats at risk. These are crucial to mitigate the impacts from environmental change that could severely affect our regional and national economies, as well as the style and quality of life of current and future generations.Read moreRead less
Monsoon extremes, environmental shifts, and catastrophic volcanic eruptions: quantifying impacts on the early human history of southern Australasia.

The coincidence of a long, diverse Australasian human history with Earth's greatest climate systems presents the Australian and Indonesian communities with unrivalled opportunities for scientific discovery. Our study will improve understanding of global climate change, environmental shifts, volcanic catastrophes, and their role in early human dispersal, and extinction, in Australasia. The significance of the results will extend to the modern world, where human behaviour modifies, and is modified by, climate and environment. Integration of research strengths in Australia and Indonesia will contribute to an improved bilateral relationship in science, education, and training, and engage the public in the excitement of scientific discovery.Read moreRead less
Unravelling Western Australia's Stormy Past - A Precisely-Dated Sediment Record of Cyclones over the past 7000 years. Australia has a vast coastline, much of which is vulnerable to cyclone impact. Clearly, historical human experience does not comprehend what the climate system is capable of in terms of epic storms. Our effort to understand the storm risks of the past is complicated by the limited length of the instrumental record which reaches back only 150 years of European settlement in tropic ....Unravelling Western Australia's Stormy Past - A Precisely-Dated Sediment Record of Cyclones over the past 7000 years. Australia has a vast coastline, much of which is vulnerable to cyclone impact. Clearly, historical human experience does not comprehend what the climate system is capable of in terms of epic storms. Our effort to understand the storm risks of the past is complicated by the limited length of the instrumental record which reaches back only 150 years of European settlement in tropical areas of Australia. This project will reconstruct the history of storms and cyclones using sedimentary signatures in Western Australia over the past 7000 years to assess storm and cyclone risks under changing future climates in a regional context.Read moreRead less
Stable water isotopic simulation and analysis to improve Earth System models and deliver better predictions of Australian water resource vulnerability. As Australia's challenges in environmental sustainability rival those anywhere on Earth, we must be clever in our diagnosis of susceptibility and insightful in proposed remedies. Climate change and variability have impacts on people and society that must be managed effectively whatever their causes. Of importance to Australia is the availabilit ....Stable water isotopic simulation and analysis to improve Earth System models and deliver better predictions of Australian water resource vulnerability. As Australia's challenges in environmental sustainability rival those anywhere on Earth, we must be clever in our diagnosis of susceptibility and insightful in proposed remedies. Climate change and variability have impacts on people and society that must be managed effectively whatever their causes. Of importance to Australia is the availability of water for drinking and agriculture. The new, interdisciplinary ARC network for Earth System Science provides models for novel and synergistic research such as naturally occurring water isotopes as a tool for improving predictive skill and confidence. We exploit these and leverage international programs to improve regional hydro-climate and water resource understanding in Australia.Read moreRead less
Dynamic networks in a patchy landscape: will species interactions adjust to increased climatic extremes? This project addresses pressing questions on how increased climatic extremes will affect species diversity in arid Australia, building on the longest ecological dataset available for the continent's vast but fragile inland landscapes. Our tests of key ideas about strong interactions among species, their role in building resilient communities and conserving biodiversity, will generate consider ....Dynamic networks in a patchy landscape: will species interactions adjust to increased climatic extremes? This project addresses pressing questions on how increased climatic extremes will affect species diversity in arid Australia, building on the longest ecological dataset available for the continent's vast but fragile inland landscapes. Our tests of key ideas about strong interactions among species, their role in building resilient communities and conserving biodiversity, will generate considerable international interest, while our focus on interactions of species at water sources will address knowledge gaps to inform best practice in managing converted pastoral lands. The results will contribute to retaining healthy functioning ecosystems, and the vital production systems they support, as the global climate changes.Read moreRead less
A new paradigm for catchment management: detection, forecasting and management of water catchments with multiple steady states. Understanding the response and recovery of Australia's water catchments to climatic change and variability is become increasingly urgent. Our catchments are vulnerable because there is a fundamental gap in our understanding of how they recover from high or low rainfall periods. This project will: a) advance water management concepts; b) build tools to understand how and ....A new paradigm for catchment management: detection, forecasting and management of water catchments with multiple steady states. Understanding the response and recovery of Australia's water catchments to climatic change and variability is become increasingly urgent. Our catchments are vulnerable because there is a fundamental gap in our understanding of how they recover from high or low rainfall periods. This project will: a) advance water management concepts; b) build tools to understand how and when catchments might switch to new states when hit by a disturbance; and c) identify how best to build the buffering capacity to reduce the chance of a switch occurring. The project will make Australia's groundwater and streamflow resources more secure and make Australian researchers and water resource managers world leaders in the emerging science of catchment resilience.Read moreRead less
Derivation of long-term hydroclimatic sequences for water resources engineering, management and planning. This project aims to develop in-situ reconstructions of flood and drought occurrence in the Sydney Warragamba catchment. The unique approach will utilise two complementary methods to provide robust insights into historic variability at the location of interest. The derived sequences will be used to augment the instrumental record, the sole basis for current drought risk assessment.

This project aims to develop in-situ reconstructions of flood and drought occurrence in the Sydney Warragamba catchment. The unique approach will utilise two complementary methods to provide robust insights into historic variability at the location of interest. The derived sequences will be used to augment the instrumental record, the sole basis for current drought risk assessment. A key outcome will be an accurate appreciation of long-term drought occurrence. This will also provide a stronger basis for utilising climate information in guiding day-to-day reservoir and water supply management. The proxy histories are of key importance in estimating future flood and drought risk assessments for water resources management and planning.Read moreRead less
The history of North Stradbroke Island's wetlands: defining natural climate variability in south-east Queensland and improving ecosystem management. South-east Queensland has among the fastest growing populations in Australia. It has also experienced severe drought lasting more than a decade. These combined pressures have led to the expenditure of more than $9 Billion on water resource development. However, it is not known whether the current drought is part of a natural cycle (or, importantly, ....The history of North Stradbroke Island's wetlands: defining natural climate variability in south-east Queensland and improving ecosystem management. South-east Queensland has among the fastest growing populations in Australia. It has also experienced severe drought lasting more than a decade. These combined pressures have led to the expenditure of more than $9 Billion on water resource development. However, it is not known whether the current drought is part of a natural cycle (or, importantly, if it represents the worst extremes in such a cycle). We will determine whether this is the case and, in doing so, contribute to national and international debates about the role of human-induced vs natural climate change.Read moreRead less
A new flood design methodology for a variable and changing climate. The extreme temporal and spatial variability of Australia's rainfall affects the quantity and quality of water resources, the productivity of agricultural systems, and aquatic and terrestrial ecosystems. Given the impact of extreme events such as floods and the massive investment in water-related infrastructure, evaluation of these risks is an issue of national economic and environmental significance. Monte Carlo simulation tech ....A new flood design methodology for a variable and changing climate. The extreme temporal and spatial variability of Australia's rainfall affects the quantity and quality of water resources, the productivity of agricultural systems, and aquatic and terrestrial ecosystems. Given the impact of extreme events such as floods and the massive investment in water-related infrastructure, evaluation of these risks is an issue of national economic and environmental significance. Monte Carlo simulation techniques will quantify the risks associated with current and future climate change, and the combined risks that come from multiple sources, such as from coastal tides and storm runoff. This research will provide a new spatial framework for calculating risk as well as tools to evaluate flood risk.Read moreRead less
The Indian Ocean Dipole, Australasian drought, and the great-earthquake cycle: Long-term perspectives for improved prediction. The protracted drought across Australia and Boxing Day 2004 earthquake in Sumatra defied prediction, and are causing incalculable environmental, economic, and social harm.

The protracted drought across Australia and Boxing Day 2004 earthquake in Sumatra defied prediction, and are causing incalculable environmental, economic, and social harm. Knowledge of past climate extremes will enhance our ability to predict climate change, and alleviate adverse affects for Australasian nations who miss-out in the future redistribution of life-giving moisture. Insights into the great-earthquake cycle will help fulfil Australia's responsibility to predict tsunamis, for the benefit of nations fringing Australasian seismotectonic zones. Development of improved techniques in palaeoclimatology, palaeoclimate modelling, and palaeoseismology will provide new collaborations and opportunities for research, training, and education.Read moreRead less
