Cockatoo Island Wareamah is a UNESCO World Heritage Site at the confluence of the Parramatta River and Lane Cove River in Sydney Harbour, New South Wales, Australia. Cockatoo Island is the largest of several harbour islands that were once heavily timbered sandstone knolls. Originally the Island rose to 18 m (59 ft) above sea level and was 12.9 hectares (32 acres) but it has been extended to 17.9 ha (44 acres) and is now cleared of most vegetation. Called Wa-rea-mah by the Indigenous Australians who traditionally inhabited the land prior to European settlement, the island may have been used as a fishing base, although physical evidence of Aboriginal heritage has not been found on the island.Between 1839 and 1869, Cockatoo Island operated as a convict penal establishment, primarily as a place of secondary punishment for convicts who had re-offended in the colonies.Cockatoo Island was also the site of one of Australia's biggest shipyards, operating between 1857 and 1991. The first of its two dry docks was built by convicts. Listed on the National Heritage List, the island is significant for its demonstration of the characteristics of a long-running dockyard and shipbuilding complex, including evidence of key functions, structures and operational layout. Cockatoo Island contains the nation's most extensive and varied record of shipbuilding, and has the potential to enhance understanding of maritime and heavy industrial processes in Australia from the mid-19th century.In July 2010, UNESCO proclaimed Cockatoo Island as a World Heritage Site, and has been managed by the Sydney Harbour Federation Trust since 2001.

Snapper Island (previously known as Schnapper Island) is a 1.65-hectare (4.1-acre) island in Sydney Harbour, Australia. It lies in the main channel of the western section of the harbour, upstream of the Sydney Harbour Bridge, adjacent to the Sydney suburb of Drummoyne. The island was originally a rocky outcrop, but in 1931-2 it was increased in size over seven times by land reclamation, and reshaped into the general plan form of a ship. Since then it has been used as a training depot by the Sea Cadets, and as a museum. Today it is in the hands of the Sydney Harbour Federation Trust, who are charged with planning a new future for it.Snapper Island is the smallest island in the harbour and more than the others has been reshaped significantly by human intervention.

Spectacle Island is an island in the Parramatta River and Sydney Harbour, in Sydney, Australia. It lies in the main channel of the western section of the harbour, upstream of the Harbour Bridge, adjacent to the Sydney suburb of Drummoyne. The island is historically significant as it is the oldest naval explosives manufacturing and storage complex in Australia (from 1865). Originally built to store government gunpowder, the complex was converted to store naval munitions in 1893, for which purpose it hosts storesheds, jetties and an internal railway system. The island has been significantly increased in size by the use of waste from the nearby Balmain Colliery. Today, the island is a depository of heritage items of the Royal Australian Navy, and also is the home of Training Ship Sydney, a unit of the Australian Navy Cadets. Spectacle Island was added to the Commonwealth National Heritage List in June 2004.
