Garden Island Naval Precinct
The Garden Island Naval Precinct, incorporates Fleet Base East, including the Garden Island Dockyard and adjacent facility Sydney Maritime Headquarters (MHQ) at Potts Point. The precinct is the main naval base in Australia and has the largest repair and refitting dockyard in Australia. Originally established as a British naval Depot, the island developed slowly from the early colonial days, with the greatest spurt occurring during World War II. This period saw massive building programs including the construction of the Captain Cook Graving Dock and land reclamation by 1945 that joined the island to the mainland at Potts Point. The dock was then the largest of its kind in the southern hemisphere. The Garden Island facility was for a long period known as HMAS Penguin, after the survey vessel, later depot ship, built in 1876. The Garden Island establishment was commissioned at HMAS Penguin until 1 January 1943. At this time, the base was renamed HMAS Kuttabul in memory of the loss of that depot ship in the Japanese attack of Sydney Harbour.
