METRONET Karnup Station funding: planning and interface notes for engineers
Reviewed by Tom Sullivan
First reported on Roads & Infrastructure (AU)
30 Second Briefing
Western Australia has allocated $10 million to complete detailed planning and approvals for the new METRONET Karnup Station on the Mandurah Line, with construction targeted to start in 2028. The project, previously deferred in favour of the now-operational Lakelands Station, will add an infill station between Warnbro and Mandurah to serve the rapidly growing southern coastal suburbs. Early work will focus on rail alignment interfaces, station access and parking layouts, and integration with surrounding road upgrades and bus interchanges.
Technical Brief
- Planning work will define station access geometry, including car park footprint, access roads and pedestrian links.
- Early design phase will need rail possession planning for future tie-ins and signalling integration.
- Coordination with surrounding land development is critical to safeguard corridors for active transport and feeder traffic.
Our Take
Western Australian Government transport pieces in our database increasingly cluster around the Kwinana–Rockingham corridor, with the Westport road links (2026) and now METRONET Karnup Station both signalling long-term freight and commuter reconfiguration south of Perth.
The relatively modest $10 million planning allocation compared with the $1.1 billion Westport and desalination JV schemes in our coverage suggests Karnup is being sequenced as an enabling node rather than a headline megaproject, likely to be bundled with broader METRONET staging decisions closer to 2028.
With Lakelands Station already in operation, adding Karnup on a similar coastal strip gives the State Government more flexibility to densify infill rather than extend greenfield sprawl, which in turn can defer or downsize some future road-capacity upgrades flagged in other WA infrastructure stories.
