The campsite allowed adventurers to stay overnight on the island. The island is small like that of Kusu Island in Singapore and is very walkable though many of the old prison cell buildings are on the upper side of a hill slope. The eerie Dog Leg Tunnel which was used to transport resources and used as a bomb shelter during the World War made me shivered as the cold wind stirred its way in the tunnel. As such, we observed there were steel beams, Turbine Shop and remnants of some of the heavy machineries in the Industrial Precinct and the Ship Design Precinct. During the First World War, it was the dockyard of the Australian Navy, and several slipways were constructed. Shipbuilding on the island began in 1870. The island has a remarkable history as a shipbuilding and ship repair facility. Many lived in extremely cramp and unhygienic conditions and many perished and died of infectious diseases as a result. The convicts were forced to work in harsh conditions on the island sandstone quarries and as construction workers for the Fitzroy Dry Dock on the island. The island is notably surrounded by shark infested waters which made it difficult for the convicts to escape. Convicts were shipped here from Great Britain to be confined in solitary cells. This island is a rare UNESCO World heritage site renowned for her historic heritage site as a ex-convict penal establishment between 18. There must be something fascinating here to attract visitors and we quickly made a prompt decision to alight at this island and postpone our river cruise.

We were on a ferry cruise to Parramatta, appreciating the beautiful skyline and gorgeous coastline of Sydney harbor and that of the suburban when I noticed many passengers alighted at the jetty of Cockatoo Island.
