South Australia is one among the six states of the country of Australia.The terrain consists largely of arid and semi-arid rangelands, with several low mountain ranges in which the most important mountains are the Mt Lofty-Flinders Ranges system which extends north about 800 kilometres (500 mi) from Cape Jervis to the northern end of Lake Torrens and salt lakes. The highest point in the state is not in those ranges, but Mount Woodroffe at 1,435 metres (4,708 ft) in the Musgrave Ranges in the extreme northwest of the state.[3] The western portion of the state consists of the sparsely-inhabited Nullarbor Plain fronting the cliffs of the Great Australian Bight.
The principle industries and exports of South Australia are wheat, wine and wool. More than half of Australia's wines are produced here.
South Australia has boundaries with every other Australian state and territory except the Australian Capital Territory and Tasmania. The area now known as the Northern Territory was annexed to South Australia in 1863, however it was handed over to the Federal government in 1911 and became a separate territory. South Australia's south coast is flanked by the Southern Ocean. Its mean temperature range is 29 °C in January and 15 °C in July. Daily temperatures in parts of the state in January & February can be up to 48 °C.
