In 1938, the Australian Commonwealth Naval Board 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. The vessel was initially envisaged as having a displacement of approximately 500 tons, a speed of at least, and a range of The opportunity to build a prototype in the place of a cancelled saw the proposed design increased to a 680-ton vessel, with a top speed, and a range of, armed with a 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. The need for locally built 'all-rounder' vessels at the start of World War II saw the "Australian Minesweepers" approved in September 1939, with 60 constructed during the course of the war: 36 ordered by the RAN, 20 ordered by the British Admiralty but manned and commissioned as RAN vessels, and 4 for the Royal Indian Navy. Stawell was laid down by HMA Naval Dockyard at Williamstown, Victoria on 18 June 1942. She was launched on 3 April 1943 by Mrs. J. J. Dedman, wife of the Minister for War Organisation, and commissioned into the RAN on 7 August 1943.
Operational history
RAN
The majority of Starwell’s career was spent in three areas. Initially, she served as a convoy escort along the east coast of Australia. Following this, Stawell participated in a variety of escort, minesweeping, and combat roles throughout New Guinea waters. In the final third of her career, the ship spent time in Hong Kong waters, performing minsweeping and anti-piracy duties. Stawell returned to Brisbane in November 1945. The corvette received three battle honours for her wartime service: "Pacific 1943–45", "New Guinea 1943–44", and "Borneo 1945".
RNZN
Stawell was removed from RAN service on 26 March 1946. On 5 March 1952, Stawell and three other Bathurst-class corvettes were transferred to the Royal New Zealand Navy. She was commissioned into the RNZN during May 1952 and given the prefix HMNZS. Stawell operated primarily as a training vessel until 1959, when she was placed into reserve.
