If your struggling for ideas of your next adventure, then I would highy recommend exploring Cockatoo Island. Cockatoo Island is located on Sydney Harbour and is a short ferry ride from Circular Quay.Once a peaceful natural habitat with many trees and scrubs and home to the local Aboriginal People it became an island that would house convicts and other colonial requirements. It more recently was an island trandformed into a major ship building yard, with many of the original buildings still standing.
You can explore the two tunnels that have been cut through the sandstone directly through the island. Walk through the old buildings and explore the old dry docks whilst admiring the tall cranes that have since ceased operation. Venturing to the top of the island you can explore the old convict sector and an amazing hall, that has been restored.
For the more adventurous you can even camp or book accomodation on the island and experience all the glory after dark. There are even audio tours which give a great explantion all over the island.
Part of the old ship yard housed an art exhibit which within the old work shops of n old ship yard gave a great atmosphere.
Best of all the entrance to the island is free and just requires you to pay for the ferry ride, though the audio tours my cost something extra its well worth the effort.
Looks like they have more plans to restore more parts of the island, so who know if the admission will be free for ever.
