Extensive Aboriginal ethnographic and archaeological surveys involving Traditional Owner groups have been completed.

Places customarily used by, or traditional to, the Aboriginal people of Western Australia are protected under the Aboriginal Heritage Act, 1972. The preferred alignment for the road will require disturbance of heritage sites, therefore, the proposed project will be submitted to the Aboriginal Cultural Material Committee and Minister for Indigenous Affairs. This application will be supported by a report detailing the outcome of the archaeological and ethnographic (study of human culture) investigations, surveys and consultation undertaken during the course of the project.

Aboriginal Heritage is also protected by the Commonwealth through the provisions of the Aboriginal and Torres Strait Islanders Heritage Protection Act, 1984, which is administered by the Department of the Sustainability, Environment, Water, Population and Communities (DSEWPaC - formerly DEWHA).

Non-Indigenous heritage is also afforded legislative protection. At a local government level, the disturbance of any locally significant heritage features listed in a council’s Municipal Inventory of Heritage Places requires council approval. The City of Cockburn lists a number of the site’s exotic trees within its inventory, and the team must ensure that any negative impacts on these trees are minimised and/or mitigated as part of the proposal.

Investigations have been undertaken to identify any additional non-Indigenous heritage values within the project area and consultation with the Heritage Council of Western Australia (HCWA) and the Australian Heritage Council (AHC) has commenced.
