Perth 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 2.02 million (as of 30 June 2014) living in Greater Perth. Perth is part of the South West Land Division of Western Australia, with the majority of the metropolitan area of Perth located on the Swan Coastal Plain, a narrow strip between the Indian Ocean and the Darling Scarp, a low coastal escarpment. The first areas settled were on the Swan River, with the city's central business district and port (Fremantle) both located on its shores. Founded in 1829 as the administrative centre of the Swan River Colony, Perth became known worldwide as the "City of Light" when city residents lit their house lights and streetlights as American astronaut John Glenn passed overhead while orbiting the earth on Friendship 7 in 1962.

Melbourne is the capital and most populous city in the state of Victoria, and the second most populous city in Australia. The Melbourne City Centre (also known as the "Central Business District" or "CBD") is the hub of the greater geographical area (or "metropolitan area") and the Census statistical division—of which "Melbourne" is the common name. As of June 2009, the greater geographical area had an approximate population of four million. In Southbank, the Melbourne Arts Precinct is site of Arts Centre Melbourne – a performing arts complex – and National Gallery of Victoria, displaying Australian and Indigenous art.
