HMAS Arunta (I30/D5/D130) was a Tribal-class destroyer of the Royal Australian Navy (RAN). Named for the Arrernte Aborigines, the destroyer was laid down in 1939 and commissioned into the RAN in 1942. Arunta fought during the second half of World War II; initially as a convoy escort and patrol ship, then in the shore bombardment and amphibious landing support roles while attached to the United States 7th Fleet. During the war, she was responsible for sinking Japanese submarine RO-33 off Port Moresby on 24 August 1942, and earned five battle honours (one of which was later rescinded). After the war's end, Arunta underwent two deployments to Japan as part of the British Commonwealth Occupation Force.
