Murray–Darling Basin


Accountability Statement

  1. This water accounting report has been prepared and presented in accordance with the Exposure Draft of the Australian Water Accounting Standard 1, with the following exceptions:

    • No Assurance Statement was prepared because the standard for, and practice of, assurance of water accounting reports have yet to be developed.
    • The Accountability Statement does not present information that would assist users to understand and evaluate the accountability of water managers because of the impracticality of doing so in this report.
    • Notes on the quantification approaches and levels of uncertainty are incomplete because the knowledge base is often inadequate.
    • No information is disclosed about material events that occurred after 30 June 2010, such as extreme precipitation and significant water rights purchases. This information is publicly available elsewhere.
    • Some groundwater-related flows and changes in the water accounting statements have been offset, due to limitations in the available quantification approaches.
    • No information is disclosed on discrete segments of the Murray–Darling Basin because it was not feasible to do so for this reporting period.
    • The water accounting statements recognise two volumes, at line items 14.10 and 25.6, which could not be quantified with representational faithfulness but which are material.
    • No information is disclosed on contingent water assets and liabilities.
    • No information is disclosed on the future prospects of the Murray–Darling Basin region.

  2. The report has been compiled from the best data obtainable in the time available to assemble it from a number of sources, as detailed in the water accounting statement Notes. Some data quality compromises have been made by the Bureau of Meteorology for the sake of a nationally-consistent approach to report preparation and presentation.
  3. All significant and specific interpretations of the Exposure Draft of the Australian Water Accounting Standard 1 for the purpose of the preparation of this report are explained in the significant water accounting policy Notes. The Bureau of Meteorology is responsible for all of these interpretations.
