Tunnel 1 reopens for public access on Cockatoo Island / Wareamah

Dedicated to enhance the amenity of its extraordinary places on Sydney Harbour, the Harbour Trust continues to carry out significant works to ensure they remain safe, accessible and enjoyable. These works included a re-lining project for Tunnel 1, also known as the 'Straight Tunnel', which has been closed for structural review since June 2020.

Shipping containers have temporarily been inserted into the tunnel, providing a secure passageway for visitors between the waterfront campground on the northern apron and the docks precinct on the southern apron. They will also be used as shelter for visitors and staff during emergencies or inclement weather. The containers will remain in place until more permanent steps can be taken to repair the inner lining of the tunnel and return to its original state. 

The reopening of Tunnel 1 marks a significant milestone for Cockatoo Island / Wareamah, offering visitors a safe and convenient route to explore the island's diverse attractions. Plan your trip to Cockatoo Island to explore the tunnel in person.
