Perth Rental Market 2026: Vacancy Rates, Rents, and What Landlords Should Expect

If you ask most Perth landlords how the rental market is performing, they'll tell you properties are leasing within days of being listed. That's not anecdote — it's a consistent outcome of a vacancy rate that has been hovering near 0.6% across the metropolitan area. To put that in context, a market is generally considered to favour tenants when vacancy exceeds 3%. Perth has been operating at roughly a fifth of that level, and there is no near-term pipeline that's going to resolve it.

For investors already holding Perth property, the current conditions are the most favourable in at least a decade. For those evaluating whether to enter, understanding the underlying mechanics matters more than headline yield figures.

What's Driving the Vacancy Crunch

Three structural forces are operating simultaneously to compress Perth's rental supply.

Population growth outpacing construction. Western Australia has been absorbing significant interstate migration — primarily from NSW and Victoria — as eastern state residents seek more affordable living costs and housing prices. International migration has also recovered strongly post-pandemic. Every new household arriving in Perth needs somewhere to live. The construction sector has been unable to match that formation rate, constrained by trade labour shortages and elevated materials costs that pushed project timelines well beyond original completion dates.

The short-term rental effect. The growth of platforms like Airbnb and Stayz pulled a meaningful volume of long-term rental stock into the short-stay market, particularly in inner-city and coastal locations. The WA government's 2024 STRA regulations — which cap unhosted short-term rentals in the metropolitan area at 90 nights per year — were partly a direct response to the impact this was having on long-term rental availability. Some stock has begun returning to the residential market, including through a state government $10,000 incentive for STRA operators who convert to 12-month leases.

The 2024 tenancy reforms. The Residential Tenancies Amendment Act 2024 restricted rent increases to once every 12 months (previously permitted every six months). In a rapidly rising market, this compressed landlords' ability to keep pace with prevailing market rents mid-tenancy. Some landlords responded by pricing new leases more aggressively upfront, while others chose to leave properties vacant briefly rather than lock in a rate they considered below market for 12 months. Neither dynamic increased overall rental supply.

Current Vacancy Rate and What It Means

Perth's vacancy rate has been near 0.6%, though more recent data shows a gradual softening toward the 2.0% to 2.6% range across 2025 and 2026 as some of the intensity has eased. Even at 2.5% vacancy, Perth remains well below the 3% mark that represents a balanced market, and well below Sydney (which has seen vacancy soften more substantially) or Melbourne.

A 2% to 2.5% vacancy rate in practice means properties are typically leasing within 16 days of listing. For investors, this translates to very low void risk — the gap between a tenancy ending and the next tenant commencing is short, protecting cash flow.

The areas where vacancy remains most compressed are the outer growth corridors feeding commuter demand — Baldivis, Alkimos, Ellenbrook, and their surrounding suburbs — where new household formation is concentrated but new housing completions lag behind permits. Inner Perth has marginally more availability due to apartment turnover patterns.

Perth Median Rents

Perth's median house rent sits at approximately $690 per week. Unit rents track around $650 per week. Both represent substantial increases from levels seen in 2021 and 2022, and the trajectory has been consistently upward as vacancy has remained below equilibrium.

The 12-month rent increase restriction introduced in the 2024 reforms means landlords can only adjust rent once per year, with a minimum of 60 days' written notice. For new tenancies, there's no restriction on the initial asking price — landlords can price at market. The restriction applies to increases during an ongoing tenancy.

For investors modelling forward cash flows, the practical implication is that if a tenant renews and you want to capture any rental growth, you have one opportunity per year to do so. Setting the initial rent accurately at market rate is more important than it was when six-monthly reviews were permitted.

What Happens if Vacancy Softens Further

There are scenarios in which Perth vacancy could ease more substantially. A significant increase in completed residential supply — particularly apartment projects in the inner-to-middle ring — would add stock. A cooling in net interstate migration, perhaps driven by a recovering eastern states affordability situation, would reduce demand growth.

The most likely scenario over the medium term is a gradual normalisation rather than a sharp reversal. Construction completions are increasing but slowly. Migration patterns remain in WA's favour while the state's resource economy continues to generate above-average wages. The WA Government's infrastructure pipeline — $10.3 billion in committed spend — is a further population attractor.

Even a normalised Perth vacancy rate of 3% to 3.5% would still support strong rental demand and low void risk for landlords. It would not, on its own, collapse rental prices — supply additions that bring vacancy up typically stabilise rather than sharply reduce rents.

Regional Rental Markets Beyond Perth

Outside the metropolitan area, regional WA rental markets are in many cases even tighter than Perth. Geraldton currently reports vacancy around 1.1%, with intense tenant competition for a limited stock of well-maintained houses. The city's role as a regional service hub for agricultural, port, and mining support industries generates diversified rental demand that's less exposed to single-industry volatility than the Pilbara towns.

Busselton and the South West wine region present an unusual market dynamic: the residential rental market is severely constrained (the City of Busselton has as few as 31 long-term rental listings at any given time), while the short-term Airbnb market is extensive. For landlords willing to manage a long-term residential tenancy in this region, the premium over median metropolitan rents is substantial — precisely because supply is so thin.

How to Use Vacancy Data When Evaluating Perth Suburbs

When assessing a specific suburb, vacancy rate tells you about demand strength but not tenant quality or management intensity. A suburb with 0.5% vacancy and a high proportion of social housing or short-cycle tenancies may still require more active management than a suburb at 1.5% vacancy with stable long-term tenants.

The most useful approach is to cross-reference suburb-level vacancy data from REIWA with median days-on-market for rentals and tenant demographic data. Suburbs where properties lease quickly, tenants stay for extended periods, and rent arrears rates are low represent the most defensible rental income positions.

The Western Australia Investment Property Guide covers suburb-level rental market analysis alongside the full acquisition cost model, tenancy law obligations, and portfolio structuring considerations.

Practical Implications for Perth Landlords

The current market conditions carry practical implications for how you manage a Perth rental property. With vacancy this low, the temptation is to set rents above market on the assumption someone will pay it. The more useful discipline is setting rents at or just below market to attract the strongest tenant pool and reduce vacancy at turnover. The annual rent increase restriction means you want the right tenant in place for the long term, not a tenant who leaves after 6 months because they found something equivalent for less.

Property management quality matters more in a tighter legal environment. The 2024 reforms created additional procedural obligations around pets, modifications, rent increases, and disputes. A good Perth property manager is worth the 8–10% management fee if they handle these compliance requirements correctly and maintain tenant relationships that reduce turnover. A cheap manager who misses notice periods or handles pet requests incorrectly will create more expensive problems.
