Western Australia is a state occupying the entire western third of Australia. It is bounded by the Indian Ocean to the north and west, the Great Australian Bight and Southern Ocean to the south,the Northern Territory to the north-east and South Australia to the south-east. Western Australia is Australia’s largest state with a total land area of 2,529,875 square kilometres (976,790 sq mi).

The first European visitor to Western Australia was the Dutch explorer Dirk Hartog, who visited the Western Australian coast in 1616. The first European settlement of Western Australia occurred following the landing by Major Edmund Lockyer on 26 December 1826 of an expedition on behalf of the New South Wales colonial government. He established a convict-supported military garrison at King George III Sound, at present-day Albany, and on 21 January 1827 formally took possession of the western third of the continent for the British Crown. This was followed by the establishment of the Swan River Colony in 1829, including the site of the present-day capital, Perth.

York was the first inland settlement in Western Australia. Situated 97 kilometres east of Perth, it was settled on 16 September 1831.
