HMAS Kookaburra (A331) was a boom defence vessel of the Royal Australian Navy (RAN), which served during World War II.


Kookaburra was of three ships ordered by the Royal Australian Navy for use as boom-net defence vessels.[1] She was laid down by Cockatoo Docks and Engineering Co. in Sydney on 4 April 1938, launched on 29 October 1938, and commissioned into the RAN on 28 February 1939.[2]

Operational history

Originally used as boom defence ship and anti-submarine training vessel in Sydney, Kookaburra was transferred to Darwin in April 1940.[2] The ship served as a boom defense and examination vessel in Darwin, and remained there until the end of World War II, with the exception of a refit in Brisbane between September 1942 and February 1943.[2]

On 15 January 1946, Kookaburra was paid off into reserve, was briefly recommissioned for a voyage to Sydney in 1950, and underwent conversion to a "Special Duties Vessel".[2] Kookaburra was recommissioned again on 11 May 1956 as a survey and general duties ship.[2]

In July 1952, the ship visited Brisbane.[2] During this visit, a paperboy delivering to the ship fell overboard and was rescued by two personnel from Kookaburra.[2]

Decommisioning and fate

Kookaburra was decommissioned for the final time on 3 December 1958.[2] She was marked for disposal on 24 June 1965,[2] sold in August 1965, and scuttled in March 1970.
