Update: May 2023

The National Parks and Wildlife Service is constructing a new 3 km walking track between Middle Head and Georges Head in Sydney Harbour National Park.

January was a busy month. NPWS arranged 2 helicopter-lift operations, delivering construction material and removing dumped rubbish that was discovered during the walking track construction. An additional helicopter-lift operation was also successfully completed by NPWS in April 2023. 

All sections of elevated boardwalk are now complete between the 1801 Fort and Georges Head. Construction is now focusing on the stone steps which will link the elevated boardwalk and walking track. These works are expected to be completed early in the second half of 2023.

Construction of the most technical section of the walking track between the 1801 Fort and Outer Middle Head will start shortly. These works include the installation of a new bridge spanning the Outer Defensive Ditch and the construction of a walking track within the smaller Inner Defensive Ditch. Once completed, this new walking track will provide visitors with access to the historic defensive system and to witness the craftsmanship required to shape these formations through the existing bedrock.

The project team is working closely with heritage experts to ensure the walking track does not impact the historic heritage of the site.

Safety closures in place

Access to the disappearing gun emplacement at Inner Middle Head has been temporarily closed by NPWS due to public safety and vandalism concerns. 

NPWS have designed and will be installing a removable platform to cover the top of the structure. This platform will ensure visitors can safety see down into the gun emplacement and will be similar to the one installed at the Georges Head. The works will be reversible and not impact the historic concrete structure. 

The temporary fencing will be removed once this work is completed later in the year.

Storytelling and interpretation

Middle Head and Georges Head’s defence heritage is of state significance. Interpretation material has been developed to help tell this story and allow visitors to understand how the fortifications functioned. This material includes signage, large-scale photographs and other objects. 

Fabrication of these items has commenced. Installation will be completed later this year. New NPWS information and way-finding signage will also be installed as part of this project.

Tours 

NPWS has partnered with the Harbour Trust to trial a new self-guided tour, In Defence of Sydney: An Interactive Walk of Middle Head/Gubbuh Gubbuh, which focuses on local military history. 

To access the interactive walk, use your phone to scan the QR code on the welcome sign near the NPWS boom gate on Middle Head Road. Keep an eye out for the colourful circle at the 5 stops as you make your way around the headland. Visitors should bring their own headphones to use on the walk, as it features audio content which will provide an insight into the area’s military history.

A survey is available at the end of the tour, and visitors are encouraged to provide their feedback. It’s a great activity to do with your friends and family!
