Wynyard Walk

Wynyard Walk is a 180-metre-long pedestrian tunnel linking the western Sydney CBD with the new waterfront precinct of Barangaroo.

During development of the concept plan, GML provided heritage advice to the design team, identifying constraints and opportunities arising from the significance of Wynyard Station, nearby heritage items, and areas of historical and Aboriginal archaeology. We developed management and mitigation strategies to conserve significant fabric, integrate heritage values into the design, and minimise impacts, enabling the project to proceed without delays. GML later excavated the site and managed heritage impacts during construction, contributing to a successful outcome.

GML was subsequently commissioned to deliver a full suite of heritage services, including a Historical Archaeology Assessment, Heritage Impact Statement, Archaeological Research Design, and an Aboriginal Heritage Assessment with community consultation. We successfully obtained an Aboriginal Heritage Impact Permit (AHIP), allowing ground works to begin and reducing the risk of construction delays associated with the discovery of Aboriginal objects.

During construction, GML monitored excavations to identify and record historical and Aboriginal archaeological evidence. Test excavations of natural soil layers revealed Aboriginal artefacts alongside intact historical archaeology. In accordance with permit conditions, these were recorded and salvaged, preserving the archaeological information while allowing works to continue.

GML worked closely with Thiess and Transport for NSW throughout the project, ensuring a positive outcome for heritage, the client and the community.
