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.
[8] 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 ordered by the RAN, 20 (including Bathurst) ordered by the British Admiralty but manned and commissioned as RAN vessels, and 4 for the Royal Indian Navy.
[3] She was launched on 1 August 1940 by the wife of the dockyard's Engineer Manager, and commissioned on 6 December 1940 under Lieut-Commander A. V. Bunyan, DSC, RD; RANR(S).
[3] Between March and May, she was assigned as a patrol and escort vessel to Singapore, before proceeding to Colombo and joining the British Eastern Fleet.
[3] She underwent refit in Colombo from September to November 1943, and was a key component in the rescue and salvage operation following the explosion of two munitions ships at Bombay on 14 April 1944.
