HMAS Reserve was a tugboat constructed by the Levingston Shipbuilding Company in Orange, Texas, in 1942. Originally acquired by the Australian Commonwealth Marine Salvage Board on 10 December 1942, she was subsequently commissioned into the Royal Australian Navy (RAN) on 17 August 1943. Designed primarily for towing and salvage operations, her service during World War II marked her as an active participant in significant Allied campaigns in the Pacific theater. During her wartime service, HMAS Reserve operated off eastern Australia and in the South West Pacific, where she played a vital support role for naval and amphibious operations. Notably, she participated in several key Allied landings in late 1943 and 1944, including at Cape Gloucester, the Admiralty Islands, Saidor, Hollandia, Wakde, Leyte, and Mindoro. Her contributions to these campaigns were recognized with the battle honour "New Guinea 1943–44," underscoring her importance in the Pacific conflict. The vessel's physical specifications are not detailed in the provided source, but her active service and participation in major campaigns highlight her significance as a naval auxiliary. HMAS Reserve remained in service with the RAN until her decommissioning on 19 October 1953. After her naval career, she was sold on 21 September 1961 to Filipino interests and renamed Polaris. As Polaris, she was involved in an ill-fated towing operation from Newcastle to Manila, aiming to tow four old vessels—three former Sydney ferries (Kalang, Koondooloo, and Kooroongabba) and a former Hobart vessel, Lurgerena. During this operation, Kooroongabba sank, and the other vessels were beached at Trial Bay while Polaris was at anchor for repairs. Despite efforts to salvage these vessels, they remained stranded, with their steel structures broken up by the waves. Polaris's involvement in this incident marks her final chapter in maritime service, after which she returned to the Philippines, leaving behind a legacy of wartime service and a dramatic post-war episode.
