HMAS Warrnambool (J202)

HMAS ''Warrnambool'' (J202), named for the city of Warrnambool, Victoria was one of 60 ''Bathurst''-class corvettes constructed during World War II, and one of 36 initially manned and commissioned solely by the Royal Australian Navy (RAN). ''Warrnambool'' sank after she hit a mine in the Great Barrier Reef on 13 September 1947. She was one of only four ''Bathurst'' class corvettes lost while in Australian service, and the only one lost after World War II.

Design and construction

In 1938, the Australian Commonwealth Naval Board (ACNB) identified the need for a general purpose 'local defence vessel' capable of both anti-submarine and mine-warfare duties, while easy to construct and operate.Stevens, ''The Australian Corvettes'', p. 1Stevens, ''A Critical Vulnerability'', p. 103 The vessel was initially envisaged as having a displacement of approximately 500 tons, a speed of at least , and a range of Stevens, ''A Critical Vulnerability'', pp. 103–4 The opportunity to build a prototype in the place of a cancelled Bar-class boom defence vessel saw the proposed design increased to a 680-ton vessel, with a top speed, and a range of , armed with a 4-inch gun, equipped with asdic, and able to fitted with either depth charges or minesweeping equipment depending on the planned operations: although closer in size to a sloop than a local defence vessel, the resulting increased capabilities were accepted due to advantages over British-designed mine warfare and anti-submarine vessels. Construction of the prototype did not go ahead, but the plans were retained.Stevens, ''A Critical Vulnerability'', p. 104 The need for locally built 'all-rounder' vessels at the start of World War II saw the "Australian Minesweepers" (designated as such to hide their anti-submarine capability, but popularly referred to as "corvettes") approved in September 1939, with 60 constructed during the course of the war: 36 (including ''Warrnambool'') ordered by the RAN, 20 ordered by the British Admiralty but manned and commissioned as RAN vessels, and 4 for the Royal Indian Navy.Donohue, ''From Empire Defence to the Long Haul'', p. 29Stevens et al., ''The Royal Australian Navy'', p. 108

Morts Dock & Engineering Co laid ''Warrnambool'' down in Sydney on 13 November 1940. She was launched on 8 May 1941 by Mrs Simpson, wife of a shipyard Director, and commissioned on 23 September 1941.

Operational history

''Warrnambool'' began her career with patrols of Bass Strait, before heading to northern waters. She was in Darwin during the bombing of Darwin on 19 February 1942, although she was not damaged. A day later she was involved in the rescue of 73 crew from the Filipino merchant vessel , following attacks by Japanese dive bombers. During the rescue, the Japanese attacked ''Warrnambool'' but she received only minor damage. Over the next 12 months ''Warrnambool'' was involved in five evacuations or rescues (including that of HMAS ''Voyager''’s crew following the destroyer running aground in September 1942), present for eighteen Japanese air raids, and transported over 4,000 troops to New Guinea.

In late 1942, the corvette moved to the east coast of Australia, where she remained until September 1944, performing convoy escort and anti-submarine patrols. Following this ''Warrnambool'' was assigned to Fremantle, Western Australia, where she performed similar duties until February 1945, when she returned to Darwin. She was present at the Japanese surrender at Koepang, Timor, on 11 September 1945.

Following the conclusion of World War II, ''Warrnambool'' performed mine clearance work in the Solomon and New Guinea Islands before moving to the Great Barrier Reef. While performing clearance work on 13 September 1947, the corvette hit a mine around 16:00 near Cockburn Reef, off the northern Queensland coast. Four sailors were killed and another 29 were injured. ''Warrnambool'' sank shortly afterward, in of water. The wreck was sold to Southern Cross Diving and Salvage on 3 July 1972. A Board of Inquiry found that there was no culpable negligence in the loss of the corvette, and praised the conduct of her crew and commanding officer. ''Warrnambool'' is the only RAN ship to be sunk by a mine. A survey conducted in 2016 by found that the wreck of ''Warrnambool'' remained largely intact.

The corvette's wartime service was recognised with three battle honours: "Darwin 1942", "Pacific 1942–45", and "New Guinea 1942".
