HMAS Anzac was a Parker-class destroyer leader that served in the Royal Navy (as HMS Anzac) and the Royal Australian Navy (RAN). Launched in early 1917 and commissioned into the Royal Navy, Anzac led the 14th Destroyer Flotilla of the Grand Fleet during the First World War. In 1919, she and five other destroyers were transferred to the RAN, with Anzac commissioning as an Australian warship in 1920. Except for three visits to New Guinea and one to the Solomon Islands, Anzac remained in southern and eastern Australian waters for her entire career. The destroyer was decommissioned in 1931, sold for scrapping four years later, stripped for parts, then towed outside Sydney Heads and sunk as a target ship in 1936.
