HMAS Reserve was a tugboat operated by the Royal Australian Navy (RAN) between 1943 and 1953.

She was commissioned into the RAN on 17 August 1943 and served off eastern Australia and in the South West Pacific.

[1] During late 1943 and 1944, she participated in the Allied landings at Cape Gloucester, the Admiralty Islands, Saidor, Hollandia, Wakde, Leyte and Mindoro.

Kooroongabba sank, and the other three vessels beached themselves at Trial Bay while Polaris was at anchor for repairs.

Their timber superstructures were broken up by the waves, and their rusted steel structures remain in the sands of the beach.
