The Steele Point Battery is a small fort, on the shores of Port Jackson in the eastern Sydney suburb of Vaucluse, Australia.

The land on Shark Point[3] was resumed from its private owners[4] and construction of the battery began in 1871[5][6] and was completed in 1874 with an additional barracks being added in 1880.

[7] It has been stated that the Shark Point battery was upgraded in 1893 to hold a BL 9.2 inch (234 mm) Mk VI breech-loading 'counter bombardment' British Armstrong 'disappearing' gun.

[8] The Shark Point battery formed part of the Sydney Harbour defences and was originally built at a time of fears of a Russian attack and other concerns such as in the withdrawal of British garrison troops, threats to British dependencies and increasing self-reliance in defence matters.

The stone lintel cover of the entry to the rear emplacement was smashed and the tunnel filled with debris, allowing water to seep in causing damage to the interior.

[10] The land on which the fort is located was granted to the state of New South Wales in 1980 and later became the responsibility of the NSW National Parks & Wildlife Service.
