Background to water accounting and assurance
There is both national and international interest in making water accounting a key part of water resources reporting.
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 national water information standards. The WASB was established in April 2009 as an independent advisory board to the Bureau of Meteorology to oversee and coordinate water accounting standards development.
The WASB has issued the Water Accounting Conceptual Framework for the Preparation and Presentation of General Purpose Water Accounting Reports (WACF) and Australian Water Accounting Standard 1, Preparation and Presentation of General Purpose Water Accounting Reports (AWAS 1).
The WACF requires that General Purpose Water Accounting Reports must be audited or reviewed, but does not establish the framework for assurance engagements on these Reports. Accordingly, the AUASB and the WASB agreed to work together to develop an assurance standard for such engagements.
