HMAS Gawler (J188/B241/A115), named for the town of Gawler, was one of 60 Bathurst-class corvettes constructed during World War II and one of 20 built for the Admiralty but manned by personnel of and commissioned into the Royal Australian Navy (RAN). The ship was laid down by BHP at its Whyalla shipyard in early 1941, launched later that year, and commissioned in 1942. Gawler was decommissioned from the RAN in April 1946. The Admiralty transferred the ship to the Turkish Navy, where she was recommissioned as TCG Ayvalik. The corvette remained in Turkish service until 1963.
