One of the most popular attractions is the historic dockyard, which dates to Cockatoo Island’s turbulent convict era. Operational from 1857 to 1992, it contributed significantly to Australia's maritime affairs – before, during and after both world wars. On this tour, you’ll visit key landmarks with the guide – including the convict-built Fitzroy Dock, the cathedral-like Turbine Shop and Sutherland Dock – and learn how the dockyard evolved across the span of 135 years. But you won’t just hear about the ships and submarines built, converted or repaired here. No, we’ll also introduce you to the island’s iconic ‘iron giants’ and tell fun and thrilling tales! You’ll learn about a beloved budgie named Trevor, a ‘funny’ fossil discovery, a daring armed robbery and the unionists who fought not just for better worker rights… but the very fate of the dockyard. This accessible tour takes place exclusively on the lower island, making it suitable for visitors with varying levels of mobility.
