HMAS Biloela was a fleet collier operated by the Royal Australian Navy (RAN) from 1920 to 1927. Biloela was built at Cockatoo Island Dockyard in Sydney, and was the first ship to be entirely built from Australian materials to an Australian design. She was completed on 5 July 1920 and supported the RAN's coal burning warships during peacetime training cruises. These warships were decommissioned in the second half of the 1920s, and Biloela was decommissioned into reserve on 14 November 1927.
