Goldfields-Esperance

The Goldfields-Esperance region is one of the nine regions of Western Australia. It is located in the south eastern corner of Western Australia, and comprises the local government areas of Coolgardie, Kambalda, Dundas, Esperance, Kalgoorlie-Boulder, Laverton, Leonora, Menzies, Ngaanyatjarraku and Ravensthorpe.

It also incorporates that area along the Great Australian Bight to the South Australian border known as the Nullarbor.

The Goldfields-Esperance region is the largest of Western Australia's regions, with an area of 770,488 square kilometres (297,487 sq mi), 70,800 square kilometres (27,336 sq mi), larger than the U.S. state of Texas or the combined area of Texas and North Dakota. It is mostly a low and flat plateau of extremely ancient Precambrian rocks which have been stable since long before the Paleozoic. Because of the extreme geological stability and the absence of glaciation since the Carboniferous, the soils are extremely infertile and generally quite saline. Consequently, the region supports the lowest stocking rates in the world: it is considered that one sheep per square mile is the maximum sustainable rate except in the small wetter area near Esperance. There are no rivers: any rainfall that is not absorbed by the dense rooting systems of the native flora percolates to form extremely saline groundwater which is very frequently too salty even for adult sheep.
