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). 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.
Just after midnight on 11 June 1943, while out to sea west of Fremantle, the corvette collided with United States Liberty Ship Henry Gilbert Costin. The night was overcast, and the ships were travelling without lights as a precaution against attacks. Three of Wallaroo's crew were killed in the collision, and the corvette sank four hours later with no further casualties while trying to reach Fremantle. The Liberty Ship received minor damage, and made it to port.
The corvette's wartime service was recognised with the battle honour "Pacific 1942".
