The Urban Development Institute of Australia (UDIA) WA has released a new report highlighting critical infrastructure requirements across seven key growth corridors in Perth. According to the report, an initial investment of approximately $596 million over four years in strategic enabling infrastructure could unlock land and facilitate the delivery of over 115,000 new homes.
Key Growth Corridors Identified
The April 2026 Perth and Peel Region Growth Corridors Infrastructure Requirements Report identifies specific areas where infrastructure investment is needed. These include North and West Ellenbrook, Bullsbrook, East Wanneroo, Yanchep-Eglinton, Mundijong, North East Baldivis, Jandakot-Treeby, and Karnup. The land in these corridors is already zoned for urban or future urban development, but development is currently constrained by infrastructure deficits.
Infrastructure Needs
The types of infrastructure required in these areas include wastewater pump stations and trunk mains, power substations and feeder networks, and sewer infrastructure. Without these essential services, housing development cannot proceed, even on land that is otherwise ready for construction.
Addressing Housing Shortages
Given the ongoing severe housing shortages in Perth, the findings of this report are significant. UDIA WA President Grant Shepherd noted that there is a common misconception that land zoned for urban development is plentiful and easy to bring to market. However, a range of constraints, including infrastructure and environmental issues, hinder progress. The report aims to inform crucial infrastructure expenditure in the 2026-27 State Budget and beyond.
“We urgently need to overcome the infrastructure constraints in these seven key growth corridors through planning, coordination, and delivery of infrastructure at the right time to catalyse development for the creation of new homes,” Shepherd said.
Infill Development Also Important
While the report focuses on greenfield development, UDIA WA acknowledges that infill development is a critical component of the housing supply puzzle. The constraints on infill are different in nature, and the institute has identified opportunities to increase the viability of medium and high-density infill projects in other reports.
Further recommendations regarding infrastructure and other key measures to accelerate housing delivery are outlined in UDIA WA’s 2026-27 Pre-Budget Submission. The organisation says it will continue to work collaboratively with the State Government to fund, plan, and deliver the critical infrastructure needed to unlock land for housing.
