Cockatoo Island

Cockatoo Island is the largest island in Sydney Harbour, located at the confluence of the Parramatta River in New South Wales. Managed by the Sydney Harbour Federation Trust, it is a UNESCO World Heritage-listed Australian Convict Site. Notable for its well-preserved convict prison buildings, former shipbuilding dockyards and industrial precincts, the island offers layered history, harbour views and adaptive reuse as a cultural venue with camping and exhibitions.

Visitors arrive by ferry to an estuarine island with distinct precincts: the convict-era plateau with sandstone barracks and mess hall, the industrial dockyards with Fitzroy and Sutherland Docks, cranes and workshops, and the waterfront campground and harbour beaches. Expect self-guided walks, audio tours, heritage buildings, large-scale art installations, cafes and panoramic views of Sydney Harbour and Parramatta River. The terrain mixes flat waterfront areas with steep, uneven historic precincts.

Known to Aboriginal people as Wareamah, the island became a convict prison from 1839 to 1869, then an industrial school and reformatory. From 1857 to 1991 it was a major shipbuilding and dockyard complex, building and repairing naval and commercial vessels, including Fitzroy Dock (completed 1857) and Sutherland Dock (1890), one of the largest graving docks in the world at the time. Inscribed in 2010 as part of the Australian Convict Sites UNESCO World Heritage listing.

Part of the Australian Convict Sites World Heritage property reflecting convict transportation and colonial expansion, and a significant example of Australia's maritime industrial heritage. The island retains Aboriginal significance as Wareamah and now functions as a cultural venue for exhibitions, festivals including the Biennale of Sydney, and public interpretation of convict and shipbuilding history managed by the Sydney Harbour Federation Trust.
