Cockatoo Island is a Heritage-listed island in the middle of Sydney Harbour.

This simple sailing boat is one of the oldest preserved fishing vessels of its kind in the world.

The world's only full-size replica of the research hut used by Douglas Mawson for his 1911-14 Australasian Antarctic Expedition.

Countless expeditions have left Tasmania to explore Antarctica, but this island state has an even deeper connection with the sea.

Bronze statues honor the brave explorers who passed through this Antarctic gateway.
