Mast of the light cruiser HMAS Sydney

The first HMAS Sydney was a Chatham class light cruiser of the Royal Australian Navy. Its crew made history in 1914, during World War I, when Sydney took part in the RAN's first ship against ship battle, the Battle of Cocos.

Sydney paid off at Sydney on 8 May 1928 and arrived at Cockatoo Island, Sydney, on 10 January 1929 where she was broken up. The foremast was moved to Bradley's Head, where it was installed as a monument to the engagement against the Emden, and later became a monument for all Australian sailors killed at war. The bow was set into the seawall at Milsons Point, under the Sydney Harbour Bridge. Both pieces of the ship are still in place as of 2006.
