The Murray River is a river in the southwest of Western Australia. It played a significant part in the expansion of settlement in the area south of Perth after the arrival of British settlers at the Swan River Colony in 1829. It should not be confused with the Murray River in southeastern Australia, which is the longest river in the country.

Perth is the capital city of Western Australia. It is the fourth most populous city in Australia, with a population of over 2.3 million within Greater Perth. It is part of the South West Land Division of Western Australia, with the majority of Perth's metropolitan area on the Swan Coastal Plain between the Indian Ocean and the Darling Scarp. The city has expanded outward from the original British settlements on the Swan River, upon which its central business district and port of Fremantle are situated.
