Australian Renters May Have Hit an Affordability Ceiling — Rents Stall Even as Vacancies Stay Tight

Australian rents have stopped rising in several major capitals even though rental vacancies remain extremely tight — a combination that suggests many tenants may have reached the limit of what they can afford.

Domain’s September 2026 Rent Report shows combined-capital house rents were unchanged at $700 per week over the quarter, while unit rents rose a comparatively modest 1.5% to $690. Sydney and Canberra recorded falls in house rents, while Melbourne, Brisbane, Adelaide and Perth recorded no quarterly growth across either houses or units.

Rents have stalled, but the rental shortage has not disappeared

The most striking feature of the September quarter is the disconnect between rental prices and rental availability.

Vacancy rates remain close to historic lows across much of the country. Brisbane’s vacancy rate was 0.7%, Adelaide’s 0.4% and Perth’s 0.4%, yet rents were flat across both houses and units in all three cities.

That is unusual. In a market with so little available stock, landlords would normally be expected to have strong pricing power.

Domain says the latest result adds weight to the view that affordability pressures are limiting tenants’ capacity to absorb further increases.

Combined-capital house rents remain at $700 a week

The combined-capital median asking rent for a house stayed at $700 per week in the September quarter, unchanged from June.

That is still expensive by historical standards. A renter paying $700 a week is spending roughly $36,400 a year before utilities, insurance, moving costs and other housing-related expenses.

And although quarterly growth has paused, annual growth remains high. Combined-capital house rents were still up 7.7% over the year, while unit rents were up 6.2%.

The latest figures therefore do not mean Australia has suddenly become affordable for renters. They show that the pace of rent increases may be slowing because households have less capacity to pay more.

Sydney and Canberra actually went backwards

Sydney house rents fell 0.6%, or $5 a week, to $835. It was the city’s first quarterly fall since December 2024.

Canberra house rents fell 1.4%, or $10, to $700 a week — the first decline in more than two years.

Both cities also recorded improved rental availability compared with a year earlier. Sydney’s vacancy rate rose to 1.2%, while Canberra reached 1.5%.

Those vacancy rates are still tight by longer-term standards, but they are materially looser than markets such as Adelaide, Perth, Hobart and Darwin.

Melbourne is flat at $600 a week

Melbourne house and unit rents both held at $600 per week.

For houses, that makes Melbourne the cheapest capital among the mainland capitals in Domain’s September data. But “cheapest” is relative: $600 a week still means more than $31,000 a year in rent.

Melbourne’s vacancy rate remained at 1.4%, unchanged from the same month in 2024 and 2025.

Brisbane, Adelaide and Perth tell the clearest affordability story

The strongest evidence of a possible affordability ceiling may be in the cities where rental supply remains exceptionally constrained but rents still failed to increase.

Brisbane house rents stayed at $700 a week and units at $660, even with a vacancy rate of just 0.7%.

Adelaide houses stayed at $650 and units at $550 while vacancies fell to 0.4% and listings were 22.8% lower than a year earlier.

Perth houses remained at $750 and units at $700 with a vacancy rate of just 0.4%.

In a conventional supply-and-demand model, this level of scarcity should support further price growth. The fact that it did not suggests tenants are increasingly responding by changing behaviour rather than simply paying more.

What renters do when rents become unaffordable

Domain economists say renters are already adapting.

That can mean moving further from city centres, taking on housemates, remaining in smaller dwellings, delaying household formation or staying longer with family.

Domain chief residential economist Dr Nicola Powell said tenants are increasingly shifting toward more affordable outer suburbs, where rent growth is still occurring.

For example, house and unit rents in Blacktown in western Sydney rose during the quarter, while North Lakes north of Brisbane also recorded increases.

Does this mean rent relief is coming?

Not necessarily.

Rental markets remain undersupplied, and the slowdown in rent growth is happening from already elevated levels.

There is also a risk that higher interest rates and weaker investor returns could reduce future rental supply if more landlords sell or fewer investors buy new properties.

Domain says slowing investor activity could constrain additional supply at the same time as borrowing costs rise, meaning the market could remain tight even if tenants cannot tolerate much higher rents.

The next test will be summer

Seasonality matters.

Rental demand in larger east-coast cities often strengthens from October into summer. If rents begin rising again during the December quarter, the September pause may prove temporary.

But if rents stay flat through the normally stronger leasing period, it would provide stronger evidence that household affordability — rather than rental supply alone — has become the dominant constraint.

The bottom line

Australia does not have a loose rental market. Vacancies are still extremely low in many cities.

What appears to be changing is the amount tenants can absorb.

With combined-capital house rents already at $700 a week and annual increases still substantial, more renters may be responding by sharing homes, moving further out or compromising on dwelling quality rather than simply agreeing to another increase.

That is why the September quarter may mark an important shift: not the end of Australia’s rental shortage, but the point at which affordability begins limiting how much higher rents can go.
