4,000 lots at Karnup: Western Australia joins the growth-corridor conversation
The WA Government's Karnup release adds 4,000 residential lots south of Perth and signals that the corridor playbook is no longer just an east-coast story.
The Cook Labor Government announced on 28 November that 4,000 new residential lots will be created in Karnup, south of Perth, as part of the state's response to chronic housing undersupply. Perth has been the strongest-performing capital city for dwelling price growth across 2024 and 2025, and Karnup is the largest single release in the metropolitan pipeline.
For east-coast investors who have under-weighted Western Australia, the Karnup release is a signal worth re-pricing. The same demand-supply dynamics that drove Brisbane outperformance in 2022-2024 are now visible in Perth's outer south corridor.
The diversification case
Cross-capital diversification inside a residential portfolio reduces concentration risk to any single state's planning, tax, or infrastructure decisions. Karnup gives east-coast investors a credible entry point into the Perth corridor story at a cost base that is still materially below Sydney or South-East Queensland equivalents.
