The first HMAS Diamantina was a River class frigate built by Walkers Limited at Maryborough, Queensland and commissioned in April 1945. Diamantina paid off to reserve on 9 August 1946, but was recommissioned as an oceanographic survey ship on 22 June 1959. As an oceanographic survey ship Diamantina was responsible for discovering the deepest point in the Indian Ocean in 1961, which was named Diamantina Trench. HMAS Diamantina paid off again on 29 February 1980, and was the last World War II-era frigate to serve with the Royal Australian Navy. Diamantina was handed over to the Queensland Maritime Museum Association and is currently on display in a dry dock adjacent to the Museum.
