Perth Housing Crisis Forces Critical Planning Decisions on Density and Affordability

Perth stands at a planning inflection point. With migration driving population growth above 2 per cent annually and median house prices in suburbs like Subiaco and Nedlands breaching $1.2 million, the Western Australian government faces urgent decisions that will define the city's character for years ahead.

The Metronet expansion—due for completion in 2028—creates the first real opportunity to reshape settlement patterns beyond the traditional sprawl corridor stretching toward Yanchep and Rockingham. Yet planners must now decide whether to genuinely incentivise medium-density development around new stations at Thornlie, Cockburn Central and Clarkson, or allow land values and developer preferences to maintain Perth's single-dwelling dominance.

The numbers are stark. Housing demand is projected to add 150,000 dwellings by 2050, yet current planning approvals suggest the market will deliver only 40 per cent of needed supply in affordable brackets. The Department of Communities and the Department of Planning are reportedly at odds over density targets for the Southern Metropolitan Region—a crucial battleground spanning Fremantle through to Kwinana.

Three decisions loom immediately. First, will the government mandate minimum apartment percentages in mixed-use zones around Northbridge, East Perth and the emerging precinct at Burswood? Second, can authorities fast-track zoning changes in established areas—Subiaco, Cottesloe, Claremont—to allow older housing stock replacement without triggering neighbourhood resistance? Third, what happens to the Stirling Naval Base's surrounding buffer zones as AUKUS commitments intensify demand for defence-sector housing near Osborne?

The state government's budget surplus, now $5.5 billion, provides fiscal capacity for targeted interventions: density bonuses for developers who include affordable units, land tax concessions for first-time buyers, or direct public housing investment in strategic corridors. Yet political will remains uncertain. Opposition to apartment zoning in established suburbs remains potent, and construction costs have climbed 23 per cent since 2023.

Infrastructure timing is equally critical. Will Transperth expand services fast enough to support denser nodes? Can water infrastructure around the Serpentine and Darling Ranges sustain urban growth? These questions aren't abstract—they determine whether Perth becomes a liveable, mixed-income city or a bifurcated metropolis where professionals cluster in expensive inner suburbs while workers face hour-long commutes.

The government must announce its Statewide Planning Strategy refresh by October. That timing will reveal whether Perth's planners have chosen to embrace urban consolidation or defer hard choices to the next administration. For renters and first-time buyers, that decision matters enormously.
