HMAS Kuttabul is a Royal Australian Navy (RAN) base located in Potts Point in Sydney, New South Wales, Australia.

[2][3] A part of Fleet Base East itself, Kuttabul occupies several buildings in the Sydney suburb of Potts Point and in the immediately adjacent Garden Island dockyard.

[2] The base is named for the steam ferry HMAS Kuttabul that was sunk while docked at Garden Island during a Japanese midget submarine attack on Sydney Harbour in 1942.

This was solved when the Australian government initially requisitioned the island (together with the naval base) under emergency wartime powers.

From its foundation until the establishment of the Two Ocean Policy and commissioning of HMAS Stirling in 1978, Kuttabul was the RAN's main naval base.
