Sydney's Cockatoo Island.

In Sydney, there was once a prison island specifically for exiling prisoners - Cockatoo Island. The small island has many historical relics, including cells, solitary confinement rooms, cellars, tunnels, and a huge granary. It also preserves a large number of industrial relics, dilapidated factories, and abandoned docks. Nowadays, these abandoned factories have a unique flavor, and it's not a bad idea to come here to take a set of post-modern heavy metal photos. It has now transformed into a fashionable art island and is a good place for many Sydneysiders to relax, camp, and unwind on weekends.
