HMAS Wallaroo (J222), named after the town of Wallaroo, South Australia, 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).[1] Wallaroo was one of only three Bathursts lost during World War II; following a collision with US Liberty ship Henry Gilbert Costin on the night of 11 June 1943.[1][2]
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.[3][4] The vessel was initially envisaged as having a displacement of approximately 500 tons, a speed of at least 10 knots (19 km/h; 12 mph), and a range of 2,000 nautical miles (3,700 km; 2,300 mi)[5] 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 15.5 knots (28.7 km/h; 17.8 mph) top speed, and a range of 2,850 nautical miles (5,280 km; 3,280 mi), 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.[3][6] Construction of the prototype HMAS Kangaroo did not go ahead, but the plans were retained.[7] 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 Wallaroo) ordered by the RAN, 20 ordered by the British Admiralty but manned and commissioned as RAN vessels, and 4 for the Royal Indian Navy.[3][8][9][10][1]
Wallaroo was laid down by Poole & Steel in Sydney on 24 April 1941.[1] She was launched on 18 February 1942 by Mrs Poole, wife of the shipyard's Chairman of Directors, and commissioned on 15 July 1942.[1]
