House prices fall in every capital city for the first time in 15 years. What happens next?

Australia's property market has reached a turning point, with the latest figures suggesting the downturn is becoming more widespread than many expected.

For the first time in 15 years, house prices have fallen across every Australian capital city in the same quarter, according to Domain's September 2026 House Price Report.

And now some of the cities that led Australia's recent property boom, including Perth, Brisbane and Adelaide, are experiencing some of the sharpest declines.

While these headlines will understandably concern homeowners and investors, I think it's important to put the figures into perspective.

Property markets move in cycles, and after several years of extraordinary growth in some capitals, a period of adjustment was always likely.

What's particularly interesting about this downturn is how quickly buyer confidence has deteriorated and the opportunities that could emerge for well-prepared investors.

Australia's property downturn is gathering momentum

Domain's latest report confirms that the September quarter marked the second consecutive quarterly decline in national house prices, with weakness spreading across all eight capital cities.

Across the combined capitals, house prices fell 4.7% during the quarter, while unit prices declined by 3.5%.

Perth recorded the largest quarterly house price decline, falling 7.4% to a median of $1,115,227, its steepest quarterly fall on record.

Brisbane wasn't far behind, with house prices dropping 5.4% to $1,152,122, ending 14 consecutive quarters of growth.

Adelaide experienced its first quarterly decline in three and a half years, with prices falling 3% to $1,095,429.

Meanwhile, Sydney house prices fell 4.7% to $1,661,167, leaving them 7.9% below their December 2025 peak, while Melbourne recorded a 3.3% decline to $1,014,335.

Even the smaller capitals weren't immune, with house prices falling 2.6% in Canberra and Darwin and 3% in Hobart.

These figures demonstrate how dramatically conditions have changed, particularly in cities where buyers had become accustomed to strong and seemingly relentless price growth.

Confidence has become one of the biggest obstacles

According to Domain Chief Residential Economist Dr Nicola Powell, declining confidence is compounding the impact of reduced borrowing capacity.

"Australia's housing market has entered a new phase in the downturn. What began as weakness concentrated in some cities has broadened considerably, with house prices now falling across every capital for the first time in 15 years," Dr Powell said.

She also highlighted how higher interest rates and persistent cost-of-living pressures are influencing purchasing decisions:

"When buyers expect prices could fall further, there is less urgency to act and greater incentive to wait."

I think this is particularly important because property markets are driven not only by economic fundamentals but also by human behaviour.

When confidence is strong, buyers are prepared to stretch their budgets because they expect prices to keep rising. But when sentiment turns negative, potential purchasers delay decisions, hoping to secure a better deal later.

This creates a cycle where fewer buyers mean less competition, longer selling periods and greater pressure on vendors to negotiate.

We've seen this pattern during previous property cycles, and as before, " this too shall pass."

The former boom markets are feeling the pressure

One of the most significant developments is the reversal occurring in Perth, Brisbane and Adelaide.

These markets benefited from strong population growth, relative affordability and tight housing supply, attracting considerable interest from investors and homebuyers.

However, successive years of strong price growth have eroded their affordability advantage, particularly when combined with higher borrowing costs.

Dr Powell described the change as a significant reversal for these previously strong markets, explaining that affordability constraints and weaker sentiment have finally caught up with them.

I suspect there's another factor at work.

Markets experiencing particularly strong growth often attract buyers who assume recent performance will continue indefinitely. When conditions change, expectations can adjust quickly, especially among purchasers attracted primarily by recent price growth.

This is why I've consistently cautioned investors against chasing property hotspots or assuming yesterday's strongest-performing markets will necessarily deliver tomorrow's best returns.

Buyers are regaining negotiating power

While falling property prices attract negative headlines, there is another side to the story.

For several years, buyers in many Australian markets faced intense competition, limited choice and pressure to make quick decisions.

Now the balance is shifting, with properties taking longer to sell, weaker auction clearance rates and vendors becoming more realistic about their expectations.

"The balance of power has shifted towards buyers."

She added that buyers with secure finances and the capacity to transact now have opportunities that have been difficult to find in recent years.

And I agree. However, investors must distinguish between a property becoming cheaper and one becoming genuinely good value.

A discount on a secondary property in a poor location doesn't suddenly make it investment grade.

On the other hand, purchasing a well-located property with strong owner-occupier appeal, scarcity and long-term growth potential at a more favourable price can make a meaningful difference to an investor's long-term results.

Units are holding up better, but the picture is changing

Another interesting finding is the relative resilience of Australia's unit markets.

Across the combined capitals, unit prices fell 3.5% during the September quarter, compared with the 4.7% decline in house prices.

UNITS | STRATIFIED MEDIAN PRICE
Capital City	Sep-26	Jun-26	Sep-25	Quarterly change	Annual change	Price peak achieved	Price from peak (%)	Price from peak ($)
Sydney	$820,890	$846,267	$838,220	-3.0%	-2.1%	Mar-26	-4.5%	-$38,425

Hobart	$584,127	$600,442	$564,549	-2.7%	3.5%	Jun-26	-2.7%	-$16,315
Darwin	$454,732	$444,857	$404,231	2.2%	12.5%	Mar-16	-4.9%	-$23,530
Combined capitals	$702,858	$727,987	$703,253	-3.5%	-0.1%	Mar-26	-4.7%	-$34,696

This reflects the affordability pressures facing buyers, with apartments and townhouses often providing a more accessible entry point into desirable locations.

However, units aren't immune to weaker conditions.

Perth recorded a 6.5% quarterly decline in unit prices, while Canberra fell 4.2%, Adelaide 3.8% and Melbourne 3.7%.

Darwin was the only capital where unit prices increased, recording growth of 2.2%.

These figures reinforce the importance of looking beyond broad property categories.

A well-located apartment in a tightly held boutique building can perform very differently from a high-density apartment in an area with substantial future supply.

The same applies to houses, where land value, neighbourhood characteristics and local supply constraints can produce vastly different investment outcomes.

What happens next?

Domain expects housing market conditions to remain subdued in the near term, with borrowing costs, affordability pressures and policy uncertainty continuing to influence buyer behaviour.

Dr Powell believes recovery will depend on improvements in both confidence and purchasing power.

"The path to recovery will ultimately depend on both confidence and purchasing power," she said.

I agree, although Australia's longer-term housing fundamentals remain important.

Our population will continue to grow, household formation will create ongoing demand, and the structural challenges associated with housing supply haven't disappeared.

Construction costs, labour shortages, planning restrictions and development feasibility continue to constrain the delivery of new housing.

These factors won't prevent prices from falling during periods of weaker demand, but they'll influence how markets perform once confidence improves.

Of course, I don't expect every capital city, suburb or property type to recover at the same pace.

Some markets will need more time to absorb their previous growth, while others could recover sooner because of stronger local economic conditions, relative affordability or tighter supply.

The bottom line

There's no doubt Australia's property markets are going through a difficult adjustment, and the latest Domain figures suggest the downturn may have further to run.

However, after watching Australia's property markets move through numerous cycles over the past three decades, I've learned that periods of uncertainty usually create opportunities for those who understand the bigger picture.

Successful investors recognise that markets rarely move in straight lines, and they don't build their strategies around trying to identify the exact bottom.

Instead, they focus on buying the right assets, maintaining appropriate financial buffers and holding quality properties long enough to benefit from future growth cycles.

For financially secure investors with a long-term perspective, today's weaker conditions may provide an opportunity to purchase properties that would have been considerably harder to secure during the boom.

And while nobody knows precisely when the next upswing will begin, history suggests buyer confidence can change much faster than the underlying fundamentals.

That's why I remain optimistic about the long-term prospects for well-selected Australian residential property, even as the market works through its current challenges.

The investors who look back on this period most favourably may well be those who used the downturn to make sensible, strategic decisions while others were waiting for certainty.
