Virgin Australia, the trading name of Virgin Australia Airlines Pty Ltd, is an airline based in Brisbane, Australia. It is one of two active airlines to use the Virgin brand, as well as the larger by fleet size. It commenced services on 31 August 2000 as Virgin Blue, with two aircraft on a single route. It suddenly found itself as a major airline in Australia's domestic market after the collapse of Ansett Australia in September 2001. The airline has since grown to directly serve 32 cities in Australia, from hubs in Brisbane, Melbourne and Sydney.

Ansett Australia was a major Australian airline group, based in Melbourne, Victoria. The airline flew domestically within Australia and from the 1990s to destinations in Asia. After operating for 65 years, the airline was placed into administration in 2001 following a financial collapse and subsequent organised liquidation in 2002, subject to deed of company arrangement. The last flight touched down on 5 March 2002.
