Passage: Brisbane ( (listen)) is the capital of and the most populated city in the Australian state of Queensland, and the third most populous city in Australia. Brisbane's metropolitan area has a population of approximately 2.5 million, and the South East Queensland metropolitan region, centred on Brisbane, encompasses a population of more than 3.6 million.
