Water resource management is one of the greatest challenges facing sustainable agriculture and urban populations across southern Australia. Key players driving catastrophic droughts in southern Australia are the tropical Indian Ocean Dipole and polar Southern Annual Mode climate systems, which affect moisture availability and transport pathways. Our collaborative research project draws together a uniquely-skilled research team to develop targeted coral, ice and cave reconstructions of these climate systems and their impacts on Australian rainfall through the last millennium. This fundamental new knowledge of the drivers of Australian rainfall variability will aid improved predictability of future changes in our valuable water resources.
