1.1.1.1 Definitions used

The Cooper subregion is located in Queensland and SA (Figure 4), and is defined by the extent of the geological Cooper Basin (see Section 1. 1.3 for further detail). The subregion spans an area of about 130,000 km². Approximately two-thirds of the subregion lies in south-west Queensland, with the remainder in north-eastern SA. Its north-eastern margin abuts the Galilee subregion. The Cooper subregion lies wholly within the Cooper Creek – Bulloo river basin, and includes a small portion of the Diamantina-Georgina river basin (see Section 1.1.5 for further detail).
