HMAS Cairns (J183), named for the city of Cairns, Queensland, 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).
Cairns was laid down by Walkers Limited at Maryborough, Queensland on 31 March 1941. She was launched on 7 October 1941 by Mrs. R. D. Walker, wife of the Works Manager of Walkers Limited, and commissioned into the RAN on 11 May 1942.
From entering service until 16 October 1942, Cairns was based in Fremantle and operated as a convoy escort, anti-submarine patroller, and minesweeper. On 16 October, the corvette was reassigned to the British Eastern Fleet and ordered to Kilindini, Kenya, arriving on 14 November.
Cairns remained with the Eastern Fleet until January 1945. Most of this time was spent on patrol or escort duties in the Indian Ocean. The corvette was reassigned to the Mediterranean from June until September 1943.  During this time, Cairns was involved in the Allied invasion of Sicily. On 11 February 1944, a convoy Cairns was assigned to was attacked by Japanese submarine RO-110. The corvette was involved in the successful destruction of the submarine, but one convoy ship was torpedoed. Following a refit in Adelaide from May to July 1944, Cairns was redeployed to Colombo, which was her base of operations until January 1945, when the corvette was sent back to Australia.
Following the end of World War II, all Admiralty-owned Bathurst class corvettes were disposed of. Cairns was paid off in Brisbane on 17 January 1946. She was immediately recommissioned into the Royal Netherlands Navy (RNN) and renamed HNLMS Ambon.
The corvette was broken up for scrap in April 1968.
