The National Water Account provides information on water in the Australian landscape as required under the Water Act (2007). It presents a financial-year summary of water availability and use across Australia's most populous locations. Each account includes a statement of assets and liabilities, and a statement of changes within these that can be broken down further into information about major storages, catchment yield, water use and allocation. Additional information about the relative contribution from surface and groundwater sources are also incorporated when available. Central account data is also presented alongside a rich climate and landscape context provided using the bureau of meteorology's extensive observation network and analysis, modelling and mapping tools. This poster presents the basics of National Water Accounts to promote discussion of how they can be used and/or modified to make them more usable into the future.
