Perth (/ˈpɜːrθ/) is the capital and largest city of the Australian state of Western Australia. It is the fourth-most populous city in Australia, with an estimated population of 2.06 million (as of 30 June 2016) living in Greater Perth. Perth is part of the South West Land Division of Western Australia, with the majority of the metropolitan area located on the Swan Coastal Plain, a narrow strip between the Indian Ocean and the Darling Scarp. The first areas settled were on the Swan River, with the city's central business district and port (Fremantle) both located on its shores.
Perth was founded by Captain James Stirling in 1829 as the administrative centre of the Swan River Colony. It gained city status (currently vested in the smaller City of Perth) in 1856, and was promoted to the status of a Lord Mayorality in 1929. The city is named after Perth, Scotland, due to the influence of Sir George Murray, Member of Parliament for Perthshire and Secretary of State for War and the Colonies. The city's population increased substantially as a result of the Western Australian gold rushes in the late 19th century. During Australia's involvement in World War II, Fremantle served as a base for submarines operating in the Pacific Theatre, and a US Navy Catalina flying boat fleet was based at Matilda Bay. An influx of immigrants after the war, predominantly from Britain, Greece, Italy and Yugoslavia, led to rapid population growth. This was followed by a surge in economic activity flowing from several mining booms in the late 20th and early 21st centuries that saw Perth become the regional headquarters for a number of large mining operations located around the state.
