American-British-Dutch-Australian Command
Initially, RAN ships served as part of the British-Australian component of the American-British-Dutch-Australian Command (ABDACOM) naval forces or in the ANZAC Force. ABDACOM was wound up following the fall of the Netherlands East Indies and was succeeded by the South West Pacific Area (command) (SWPA). The United States Seventh Fleet was formed at Brisbane on 15 March 1943, for service in the SWPA. RAN ships in the Pacific generally served at part of Seventh Fleet taskforces.
