HMAS Gascoyne (K354/F354/A276) was a River-class frigate constructed for the Royal Australian Navy during World War II. Laid down on 3 July 1942 by Mort's Dock & Engineering Company in Sydney, she was launched on 20 February 1943 by Lady Wakehurst, wife of the Governor of New South Wales, and commissioned later that year on 18 November 1943. Named after the Gascoyne River, the vessel was built to serve in wartime operations and was actively involved in the Pacific theater. Throughout her service in World War II, HMAS Gascoyne earned significant recognition for her contributions. She was present in Tokyo Bay on Victory over Japan Day, 2 September 1945, witnessing the Japanese Instrument of Surrender. Her wartime record includes five battle honours: "New Guinea 1944," "Leyte Gulf 1944," "Lingayen Gulf 1945," "Borneo 1945," and "Pacific 1945," reflecting her extensive participation in key campaigns across the Pacific region. After the war, Gascoyne was paid off into reserve on 12 April 1946. However, she was reactivated in 1959, having been reclassified as a survey and research vessel. During this period, she was outfitted with specialized equipment such as a deep-water mechanical bathythermograph, which facilitated her new role in oceanographic research. She resumed service on 8 June 1959, operating out of Sydney. Gascoyne continued in her survey role until she was decommissioned again on 1 February 1966. She was subsequently sold for scrap to the Fujita Salvage Company Limited of Osaka, Japan, on 15 February 1972. Prior to her final departure, her bathythermograph was transferred to HMAS Sprightly. The ship left Melbourne under tow for Japan on 6 July 1972, marking the end of her distinguished service. Her history highlights her transition from wartime patrols to scientific exploration, underscoring her maritime significance in both military and research domains.
