Within the Basin, an irrigated area of 1.7 million hectares of irrigated crops and
pastures produces output with a gross value of $4.6 billion. Dryland agriculture
in the Basin contributes $10.4 billion. The Basin accounts for 39 per cent of the
total value of agricultural commodities produced in Australia (Australian
Bureau of Statistics 2008).
