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.
