Water accounting in Australia

A key feature of the Australian environment is that water is relatively scarce when compared with other inhabited continents. Rainfall displays a high level of spatial and temporal variability and droughts are common. In 2004 an Intergovernmental Agreement on a National Water Initiative (NWI) was reached by Australia's national and eight state and territory governments. The NWI aims to address environmental, economic and social concerns about the current and future state of Australia's water resources. The NWI specifically calls for the preparation of annual water accounts, which clearly indicates the expected usefulness of national and regional water accounts.
