@louannwarren It ceased operations and was just left abandoned - I assume all the cranes and machinery are too heavy to move - The dockyard closed in 1992 and lay dormant for a decade until the Sydney Harbour Federation Trust assumes control of the island and embarks on major restoration works. After extensive remediation works, Cockatoo Island was opened to the public in 2007. The Harbour Trust continues to actively rehabilitate the island.
