South Australia is classed as the state in south central Australia along the Indian Ocean. It covers an area of 984,377 square kilometres (380,070 square miles). The capital of South Australia is Adelaide and it's known as the City of Churches. South Australia became a British colony in 1836 and joined the Commonwealth of Australia in 1901. The state's population is 1,4000,622 and most of those reside in the fertile coastal areas and in the valley of the Murray River which is the only navigable river and drains about one seventh of Australia then enters the sea in South Australia. The first recorded sighting of the South Australian coast was in 1627 when a Dutch ship examined the coastline.
The terrain consists largely of dry wasteland, with several low mountain ranges in which the most important mountains are the Mt Lofty-Flinders Ranges system which extends north about 800 kilometers from Cape Jervis to the northern end of Lake Torrens and salt lakes. Its principal industries and export are wheat, wine and wool. More than half the nations wines are produced here.
South Australia has boundaries with other states on the west, east, north and the south is flanked by the Southern Ocean. South Australia's temperate range is 29C in January and 15C July.
South Australia adopted their flag on 13 January 1904. The flag of South Australia is a British Blue Ensign defaced with the state badge. The badge depicts a white-backed piping shrike (magpie) with wings outstretched on a yellow disc. The state badge is believed to have been designed by Robert Craig of the Adelaide School of Arts.
