Broken Hill Complex Bioregion

The Broken Hill Complex Bioregion lies in the far west of NSW, spanning the NSW-SA border. Across these two states the bioregion has an area of 5,691,042 hectares, with 3,811,697 hectares or 66.98 per cent falling in NSW.

The bioregion occupies about 4.8 per cent of NSW and is bounded by the Murray-Darling Depression and Darling Riverine Plains bioregions in the south, and the Simpson-Strzelecki Dunefields and Mulga Lands bioregions in the north and east respectively. In SA it is bounded by another four bioregions.

The biggest city in the bioregion is Broken Hill with a population of about 20,096 (2001 Census - Australian Bureau of Statistics). There are few other towns in the bioregion.

Nearby Silverton was once the main township in the 1880s at the peak of mining activity, but it was soon overshadowed by the faster-growing Broken Hill (HO and DUAP 1996). The entire NSW portion of the bioregion lies within the Western Division.

The eastern part of the Broken Hill Complex Bioregion falls in the Murray-Darling Basin while the Darling River flows just outside the southeastern boundary of the bioregion. The bioregion includes parts of the Lake Frome, Lake Victoria, Lake Bancannia, Paroo and Darling River catchments.
