South Australia  is a state of Australia in the south of the country between Western Australia to the west and Queensland, New South Wales and Victoria to the east, and south of the Northern Territory. It was first proclaimed a colony in 1834 and unlike other states in Australia was settled entirely by free settlers from Britain from the 1830s onwards. With nearly 1.6 million people, however, the state comprises less than 10% of the Australian population and ranks fifth in population among the states and territories. However, the state covers a vast amount of land area, including some of the most arid parts of the country. With a total land area of 983,482 square kilometres (379,725 sq mi), it is the fourth largest of Australia's six states and two territories. The state also includes Kangaroo Island, Australia's third largest island which lies off the coast of the mainland in the south-east of the state.
