Cockatoo Island is located in Sydney Harbour, about 1km directly west of the Harbour Bridge. It was first settled as a penal settlement in 1839, and eight years later work began (using convict labour) to turn the Island into major shipping building and repair facility, especially for the Navy. The facilities were finally closed in 1992, and the Island remained unused until 2001, when the Sydney Harbour Federation Trust took over the control of the island and embarked on major restoration works. Work continues today, but the Island was re-opened to the public in 2007.
The old and decaying buildings and infrastructure are a wonderful source of photographs. I visited the island in October this year (2015) and here are my photos.
