HMAS Bermagui was a 402-ton auxiliary minesweeper operated by the Royal Australian Navy (RAN) during World War II.

During the war, Bermagui was attached to the naval base HMAS Maitland in Newcastle, New South Wales and served as an auxiliary minesweeper, boom defence vessel, and minefield tender.

The ship was paid off from service on 23 November 1945 and returned to her civilian owners on 22 July 1946.

She was sold in 1951 to Lumbar Operators Pty Ltd and in 1954 to Allen Taylor & Co. as a timber transport vessel.
