All three were laid down on 3 May 1943, but were cancelled and broken up on the slipways in March 1945. Instead, three Flower-class corvettes were transferred from the Royal Navy to India. The two main purposes the ships were intended for were minesweeping and anti-submarine escort. However, the corvettes found themselves performing a wide range of duties, including troop and supply transport, bombardment, assault landings support, survey and hydrography mapping, and providing aid to disabled ships. The Bathursts were seen as 'maids of all work' by the RAN, even though the design was inappropriate for some roles; being too small, too slow, or inadequately armed or equipped. It was not until March 1943 that sufficient ships were available to take the individual variations and capabilities of the Bathursts into account: prior to this, they were the first (and often only) available vessel. Because of the dual, conflicting roles of local defence vessel and ocean-going escort, Bathursts based in Australia were under two different controllers for the first part of the Pacific War; operationally under the US Navy's Naval Commander South West Pacific Area Forces (COMSOUWESTPAC), and administratively under the Naval Officer In Charge (NOIC) of the ship's homeport. Following multiple incidents where a ship would be assigned to two different tasks simultaneously; conflicts between local needs, escort schedules, and maintenance requirements; and protests from the NOIC in Fremantle and Darwin, the Australian-based corvettes were placed completely under NOIC control in May 1942. Instead of directly assigning ships to convoys, COMSOUWESTPAC would indicate that ships would be needed from a particular port for escort duties, leaving the NOIC of that port free to allocate available ships. "Bathurst"-class ships were assigned up to three different pennant numbers during the course of their career. With the exception of , all of the "Bathurst"-class corvettes were given numbers with the 'J' flag superior, designating them as minesweepers. Ships of the class that served with the British Pacific Fleet, like many other ships serving with the fleet, had their pennant numbers changed to ones with a 'B' flag superior. At the end of World War II, a reorganisation of the pennant system saw the Bathursts given new numbers with 'M' as the flag superior, which was the new designator for minesweepers.
