Australia’s housing market turns: falling prices bring opportunity, pressure and difficult choices

House prices are falling across most capital cities, but cheaper property does not necessarily mean affordable housing. Higher borrowing costs are changing what Australians can pay—and how much existing owners have left to spend.

Australia’s housing market is delivering a difficult combination: property prices are retreating while the cost of financing a home remains high.

For prospective buyers, that can mean more negotiating room without a corresponding improvement in their ability to obtain a mortgage. For existing owners, it can mean higher repayments alongside a shrinking equity buffer.

The latest complete monthly figures, covering September 2026, show national dwelling values fell 1.1%, their sixth consecutive monthly decline. Values were 5.2% below their March peak. These broader figures include houses and units.

The national direction is clearer than it was earlier in the cycle. However, the experience still differs considerably between cities—and between someone who bought years ago and someone who purchased near the peak.

House prices in every capital city

Cotality’s separate house figures, excluding units, show the following changes to 30 September 2026.

Capital city	September change	Annual change	Median house value
Sydney	−1.6%	−8.2%	$1,466,060
Melbourne	−0.9%	−7.3%	$915,119
Brisbane	−1.5%	+5.3%	$1,146,078
Adelaide	−1.4%	+6.5%	$990,531
Perth	−1.2%	+10.0%	$1,017,734
Hobart	−0.4%	+7.0%	$790,406
Darwin	+0.3%	+9.6%	$747,252
Canberra	−1.1%	−1.5%	$1,006,269

Sydney has the largest annual house price decline, while remaining the most expensive capital.

Melbourne is also substantially lower over the year, although its September fall was smaller than Sydney’s.

Brisbane is losing ground despite retaining an annual gain.

Adelaide shows the same distinction: a positive annual result alongside a falling monthly market.

Perth’s double-digit annual growth contrasts with its September retreat.

Hobart recorded a relatively modest monthly decline.

Darwin was the only capital where house values increased during September.

Canberra recorded declines over both periods.

The distinction between monthly and annual changes matters. A city can remain ahead of last year while conditions facing today’s seller deteriorate.

An annual gain describes where prices have been. Recent monthly movements give a more immediate indication of direction.

Why falling prices do not automatically solve affordability

Housing affordability has several moving parts: the purchase price, the deposit, household income and the cost of borrowing.

A lower purchase price can reduce the deposit required. However, if mortgage rates rise, a lender may approve a smaller loan because repayments consume more of the buyer’s income.

That creates a frustrating situation. A property advertised below its previous asking price may still be beyond the reach of the household that wanted it.

Existing owners face a different calculation. Their mortgage does not shrink because their home’s estimated value falls.

For illustration, a buyer who purchased a $1 million home with a $900,000 mortgage began with $100,000 in equity, before transaction costs. If its value subsequently fell to $900,000 while the loan balance remained close to that amount, most of that equity buffer would disappear.

That does not automatically force a sale. A household that can meet repayments may continue living there for many years. The difficulty becomes more acute when an owner needs to sell, refinance, relocate or cope with a loss of income.

What is the RBA trying to achieve?

The Reserve Bank’s immediate concern is inflation.

At its September meeting, the RBA increased the cash rate by 0.25 percentage points to 4.60%. It said demand growth needed to remain subdued to ease pressure on the economy and prevent high inflation becoming entrenched. It also acknowledged uncertainty about the economic consequences of the housing downturn.

Housing is one of the channels through which that policy works.

Higher interest rates increase the cost of borrowing, constrain purchasing budgets and encourage households to reconsider discretionary spending. They can also make investment and development projects harder to justify.

The RBA’s stated objective is price stability and full employment. A particular house price is not its target.

Consequently, falling property prices do not automatically trigger an interest rate cut. The bank can judge that inflation requires continued restraint even while housing weakens.

The oil problem makes the task harder

The RBA’s September statement identified disruptions to global oil supply and the spread of higher fuel costs into other goods and services as sources of inflation pressure.

This exposes a limitation of interest rate policy.

Higher Australian mortgage repayments cannot reopen an overseas shipping route or produce additional oil. What they can do is reduce spending elsewhere, limiting businesses’ ability to pass on further increases and helping contain the spread of inflation.

For households, that can feel like being squeezed twice: first by fuel and other essential costs, then by the borrowing costs intended to restrain inflation.

The policy challenge is to prevent persistent inflation while avoiding an unnecessarily severe contraction in spending and employment.

The consequences extend beyond homeowners

A housing slowdown affects more than the people buying and selling.

NAB’s October Housing Monitor reported weaker sales activity and longer selling times. It also revised its forecast to an 8% decline in combined capital city dwelling prices during 2026. That is a forecast, rather than a confirmed outcome.

Fewer transactions can mean less work for conveyancers, removalists, agents and businesses selling furniture, appliances and renovation services.

State budgets are exposed because transfer duty depends on property transactions and their value. Weaker receipts can reduce governments’ financial room unless offset by other revenue, spending changes or borrowing.

Construction presents another complication. Lower established home prices may help purchasers, but they can also make a proposed new development less competitive. If financing and building costs remain elevated, some projects may become harder to fund.

That is how weaker demand today can complicate the task of providing enough homes tomorrow.

Renters also need to distinguish between purchase prices and rents. A fall in a landlord’s property value does not itself reduce the rent a tenant pays. Rental conditions depend on available accommodation, household demand and tenants’ capacity to pay.

What happens next?

The next phase will depend on inflation, employment, lending conditions and the willingness of buyers and sellers to transact.

Stable employment would help borrowers maintain repayments. A deterioration in employment would make an already difficult adjustment more demanding.

An eventual easing in interest rates could improve borrowing capacity, but it could also revive competition for properties. That means some affordability gains from lower financing costs could be absorbed by renewed price growth.

There is no single national experience. A long-term owner with a small mortgage, a recent purchaser with a large loan and a renter saving a deposit can live in the same street while experiencing this market very differently.

The Times View

Australia should be able to accommodate a period of falling house prices without treating every decline as a national failure.

Ever-rising prices create their own damage by placing ownership further beyond the reach of working households. Yet a correction becomes dangerous when high repayments, falling equity and insecure employment arrive together.

The RBA must contain inflation. Governments must address the supply, infrastructure and construction constraints that interest rates cannot resolve.

The measure of a successful housing market is ultimately whether people can obtain suitable homes and afford to keep them.

A nation’s housing success should be measured by the security it provides, rather than the debt required to participate.
