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.[2][3] 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)[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 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.[2][5] Construction of the prototype HMAS Kangaroo did not go ahead, but the plans were retained.[6] 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 Geelong) ordered by the RAN, 20 ordered by the British Admiralty but manned and commissioned as RAN vessels, and 4 for the Royal Indian Navy.[2][7][8][9][1]
Geelong was laid down by HMA Naval Dockyard at Williamstown, Victoria on 16 October 1940.[1] She was launched on 22 April 1941 by the wife of Lord Winston Dugan, then Governor of Victoria, and was commissioned into the RAN on 16 January 1942.[1]
Operational history
After commissioning, Geelong visited her namesake city before undergoing working up trials.[1] On completion, the corvette was assigned as a minesweeper and anti-submarine patrol ship along the east coast of Australia, before being redeployed to New Caledonia on 8 March 1942 to perform similar duties.[1] In May 1942, Geelong returned Sydney, and was one of several Allied vessels located in Sydney Harbour during the Japanese midget submarine attack of 31 May 1942.[1][10] In June, the ship began convoy escort runs between Sydney and Brisbane, which continued until January 1944, when she sailed to Adelaide for a two-month refit.[1]
After the refit, Geelong briefly operated in Australian waters before being assigned to New Guinea.[1] Using Milne Bay as a base of operations, the corvette served as a convoy escort and anti-submarine patrol ship throughout the South West Pacific Area.[1]
