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).
Sydney Sydney (/ˈsɪdni/ ( listen))[7] is the state capital of New South Wales and the most populous city in Australia and Oceania.[8] Located on Australia's east coast, the metropolis surrounds Port Jackson and sprawls about 70 km (43.5 mi) on its periphery towards the Blue Mountains to the west, Hawkesbury to the north, and Macarthur to the south.[9] Sydney is made up of 658 suburbs, 40 local government areas and 15 contiguous regions. Residents of the city are known as "Sydneysiders".[10] As of June 2017, Sydney's estimated population was 5,131,326.[11]
