HMAS Bataan operating off Korea
In late June 1950, Bataan was en route to Japan for a fifth tour when the Korean War started. From early July 1950 until 29 May 1951, the destroyer operated off Korea; patrolling and blockading, escorting aircraft carriers, and bombarding shore targets. A second Korean tour occurred between 4 February and 31 August 1952, with Bataan fulfilling most of the same duties as before. Bataan was presented with the battle honour "Korea 1950–52" for her service.
In November 1953, Bataan visited Singapore. This was the only time since the Korean War, and the only time for the rest of her career, that the destroyer would leave Australian waters.
Decommissioning and fate
Bataan paid off at Sydney on 18 October 1954, and was laid up in reserve awaiting conversion to an anti-submarine escort. The conversion was cancelled in 1957, with Bataan placed on the disposal list, then sold for scrap to T. Carr and Company of Sydney in 1958.
