Consultation has now concluded. Please keep your eye on the news section of the City of Subiaco website for any project updates.


As cities become bigger and busier, the speed of traffic is well known to have a significant impact on liveability, especially within our inner-city residential streets.

Reducing speed limits to 40km per hour (from 50km per hour) on local residential streets is part of a Perth Inner City Group joint proposal across the local governments of Subiaco, Cambridge, Perth, Vincent, South Perth and Victoria Park.

Local residential streets are where our community live, work, play and connect.

This initiative builds on a successful trial by the City of Vincent, which demonstrated that lower speeds reduced accident rates, encouraged walking and cycling, and improved community satisfaction with minimal impact on travel times.

The City of Subiaco has previously reduced speed limits in some areas with positive safety outcomes. The reduction to 30km per hour on Rokeby Road has resulted in an almost 50% reduction in reported accidents in that section.

Is there anything you want to tell us about your street as we roll out the 40km per hour speed limit reduction changes? We are collecting questions and feedback on this initiative to track community sentiment and site specific nuances.

Please let us know your questions and feedback and we will update the FAQs throughout the project. Closed Thursday 15 May 2025.

    Survey outcome and next step

    From Tuesday 15 April to Thursday 15 May 2025, the local community was invited to have their say on the proposed plan for speed reductions from 50km per hour to 40km per hour on local residential streets and some local distributor roads. Consultation was undertaken via an online survey, question and feedback forms and postcards, or at two Subi Farmers Market listening posts.

    Of the responses received via the online survey, 67 per cent were supportive of the reduced limits, and 15 per cent were neutral. Positive survey respondents highlighted benefits such as increased walkability, pedestrian safety (especially for children) and reclaiming the streets for community use.

    Further feedback received at the in-person listening posts at Subi Farmers Market and postcards revealed that there is overwhelmingly positive support for the speed reduction proposal, especially for its potential to improve safety and walkability in the area.

    Following a review of all community feedback, and a technical review of the proposed area-wide speed zones, the Perth Inner City Group will submit the proposal to Main Roads WA and the Road Safety Commission for consideration.
