Environmental Protection Authority (EPA) Referral
The Environmental Protection Authority (EPA) has finalised its report on the proposed Tonkin Highway upgrade, recommending the proposal can be implemented subject to conditions which prevent impacts to the key environmental values of the Greater Brixton Street Wetlands (GBSW).
The EPA report highlights the challenges of continued development on the Swan Coastal Plain, in particular whether the EPA’s environmental factor objectives could continue to be met when cumulative effects on key environmental values were already significant.
The EPA’s report to the Minister for Environment was open for a three-week public appeal period and; closed 26 August 2024. EPA Report 1769 can be found on the EPA website.
Following assessment of the appeals, approval for the Hale Road and Welshpool Road Highway interchanges and associated upgrades to Tonkin Highway was confirmed by the Minister for the Environment was confirmed on 19 August 2025.
Environmental assessments
- March 2021: Referred the Tonkin Highway Grade Separated Interchanges – Hale Road and Welshpool Road component of the project to the Environmental Protection Authority (EPA) for assessment under Part IV of the Environmental Protection Act (1986).
- September 2019: the same component of the project was referred to the Commonwealth for assessment under the Environment Protection and Biodiversity Act 1999 (EPBC Act).

Environmental surveys
A number of different environmental surveys have been undertaken for the project between 2015 and 2024.
We have met with the Nature Reserves Preservation Group, Friends of Woodlupine Living Stream and Friends of Woodlupine Brook and plan to meet with the Kalamunda Environmental Advisory Committee. Discussions have included avoiding disturbance of native vegetation and threatened flora and fauna, as well as noise mitigation, minimising lighting pollution and revegetation. These groups provide valuable local environmental knowledge.
Our Baseline Water Quality monitoring (surface and groundwater) is continuing to assess pre and post development flows to help us retain or improve quality.
