Background to water accounting and assurance

Making water accounting a key part of water resources reporting is of national and international interest.

In 2004, the Council of Australian Governments (COAG) established the intergovernmental National Water Initiative. COAG identified the need for consistent water resources accounting that could be standardised, compared, reconciled and aggregated.

The Commonwealth Water Act 2007 reaffirmed the national importance of water information and identified new functions for the Bureau of Meteorology in water accounting, including issuing water accounting standards. The Water Accounting Standards Board was established in April 2009 as an independent advisory board to the Bureau of Meteorology to oversee and coordinate water accounting standards development.

The Board has issued the following documents:

  • Water Accounting Conceptual Framework for the Preparation and Presentation of General Purpose Water Accounting Reports
  • Australian Water Accounting Standard 1, Preparation and Presentation of General Purpose Water Accounting Reports
  • The Australian Water Accounting Standard 2  Assurance Engagements on General Purpose Water Accounting Reports
