HMAS Warramunga (I44/D123) was a Tribal-class destroyer of the Royal Australian Navy (RAN). Built during World War II, the destroyer entered service in late 1942. She was initially assigned to convoy escort duties, but was assigned to the joint Australian-American Task Force 74 in 1943, and was involved in supporting numerous amphibious landings through the South-east Asian region until the end of the war. From 1950 and 1952, Warramunga fought in the Korean War, then was converted into an anti-submarine destroyer. Returning to service in 1954, the destroyer was one of the first RAN ships to operate with the Far East Strategic Reserve, and undertook two tours with the organisation before she was decommissioned in 1959 and sold for ship breaking in 1963.

The Cockatoo Docks & Engineering Company was a ship building and maintenance company which operated the Cockatoo Island Dockyard on Cockatoo Island in Sydney, Australia, between 1933 and 1992.
