Cockatoo Island is one of the islands located in Sydney Harbour. It's around a 30 minute ferry ride from Circular Quay and was heritage listed in 2010 because of it's colonial past.
Prior to colonial times, it was used by the Eora people, who are the Aboriginal people of and around Sydney's coast.
During colonial times, it was used as a gaol, because the Norfolk Island gaols were overcrowded. Some of the convicts were on Cockatoo Island because they'd caused too much trouble on Norfolk Island, and had to be put somewhere else.
The convict sleeping quarters would have been very cold in winter, and very hot in summer with large, packed spaces full of people. Sleeping would have also been difficult, with just a lump of wood as a "pillow".
Later, it was used as a Naval shipbuilding yard. These giant clamps were used to hold steel that had to be moulded in to frames for the ships.

The island has some beautiful large, old trees.
Because it was a naval shipyard during World War II, they were concerned about it being bombed so they made these tunnels through the rock, so in case of air-raids everyone had somewhere to hide and wait it out.
These days, it has magnificent views of the harbour and the city.
You can also do some camping on-site, though I think it'd be a bit cold for me in winter.
There's still a lot more to see around the island, we'll have to revisit and see what else we can find.
