Brisbane is the state capital of Queensland and its most populous city. It is also the third most populous city in Australia, behind southern rivals Sydney and Melbourne. The city is situated on the Brisbane River on a low-lying floodplain between Moreton Bay and the Great Dividing Range in south-eastern Queensland. The local indigenous people knew the area as Mian-jin, meaning ‘place shaped as a spike’. The city is named after Sir Thomas Brisbane, the Governor of New South Wales from 1821 to 1825. Brisbane’s demonym is a Brisbanite.
