The largest island in Sydney Harbour has worn many guises, and Cockatoo Island, known to its traditional owners as Wareamah, carries the layered scars of all of them. From the 1830s it held a convict prison whose inmates quarried the sandstone and dug grain silos by hand; later it became a reformatory and industrial school for girls; and for much of the twentieth century it was one of Australia's most important shipyards, building and repairing naval vessels through two world wars. That unusual sequence saw it added, with other convict sites, to the UNESCO World Heritage list in 2010. Today the island is open to the public as a heritage site reached by ferry, and visitors can roam among the surviving convict buildings, the cavernous workshops, cranes and slipways of the shipyard, and the tunnels cut through the rock. Self-guided trails and audio tours explain the overlapping histories, while interpretive signs trace the lives of convicts, the girls held in the reformatory and the thousands of workers who once crossed the water each day to build ships. The contrast between sandstone cells and rusting industrial machinery gives the place a distinctive, slightly haunting atmosphere. Cockatoo Island has also reinvented itself as a venue and a destination in its own right. It hosts large art events and festivals, has been a key site for the Biennale of Sydney, and offers camping and accommodation in former workers' quarters, so that visitors can stay overnight on an island in the middle of the harbour. Cafes, bars and event spaces operate among the heritage structures, and the open decks deliver wide views back to the city and bridge. The mix of history, industry, art and harbour setting makes it unlike anywhere else in Sydney. Reaching the island is half the appeal, with regular ferries running from Circular Quay and other harbour wharves, and a visit can be as simple as a self-guided wander or as involved as an overnight stay in a tent or apartment. Interpretive apps, guided tours and seasonal events help bring the layered history to life, and the island is increasingly managed with a focus on recognising its deep Aboriginal heritage as Wareamah alongside its convict and industrial past. Picnic spots, a cafe and a bar give visitors places to rest between the workshops and lookouts, and the lack of through traffic makes it a peaceful spot in the middle of a busy harbour. For photographers, the mix of rusting cranes, sandstone and water views is a particular draw at sunrise and sunset.
