what is the elevation of most of western australia
Western Australia Because the only mountain-building since then has been of the Stirling Range with the rifting from Antarctica, the land is extremely eroded and ancient, with no part of the state above 1,245 metres (4,085 ft) AHD (at Mount Meharry in the Hamersley Range of the Pilbara region). Most of the state is a low plateau with an average elevation of about 400 metres (1,200 ft), very low relief, and no surface runoff. This descends relatively sharply to the coastal plains, in some cases forming a sharp escarpment (as with the Darling Range/Darling Scarp near Perth).
Mining in Australia Despite its export importance, the mining sector employs only a small proportion of the workforce â€“ roughly 129,000 Australians, representing only about 2.2% of the total labour force.[31]
