Australian capital city house prices drop for first time

For the first time in 15 years, every Australian capital city saw prices drop in the same quarter, according to Domain’s September 2026 House Price Report. Combined capitals experienced a 4.7% quarterly fall in house prices, while units declined 3.5%, marking the second straight quarterly decline and confirming the market has reached a turning point.

Former Boom Markets Lead the Downturn

Perth recorded the steepest house price decline, falling 7.4% to a median of $1,115,227, its most significant quarterly drop on record. Brisbane followed closely with a 5.4% decrease to $1,152,122, ending 14 consecutive quarters of growth. Adelaide experienced its first quarterly decline in three and a half years, with prices dropping 3% to $1,095,429.

Sydney house prices fell 4.7% to $1,661,167, leaving them 7.9% below their December 2025 peak. Melbourne recorded a 3.3% decline to $1,014,335. Even smaller capitals were affected, with Canberra and Darwin seeing 2.6% falls and Hobart down 3%.

Buyer Confidence Erodes Under Higher Borrowing Costs

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 noted that 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.”

These former boom 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.

Negotiating Power Shifts Toward Buyers

Properties are taking longer to sell across major markets, giving financially secure purchasers more opportunities to negotiate favourable deals. Auction clearance rates have weakened, and vendors are adjusting their expectations in response to reduced buyer demand.

Dr Powell noted that the balance of power has shifted toward buyers, particularly those with secure finances who can move quickly when suitable properties arise. This change follows several years of intense competition, limited choice, and pressure on buyers to make rapid decisions.

Long-Term Fundamentals Offer Stability

Despite the current downturn, long-term fundamentals remain positive. Population growth and housing supply constraints will continue to support demand, creating opportunities for strategic investors who focus on quality properties in desirable locations.

Units have shown relative resilience compared to houses, with the 3.5% quarterly decline across combined capitals less severe than the 4.7% drop in house prices. Darwin was the only capital where unit prices increased, rising 2.2%, while Perth saw the steepest fall at 6.5%. Canberra fell 4.2%.

Market cycles are a natural part of the property environment, and after several years of sustained growth, a period of adjustment was always likely. The speed at which buyer sentiment has shifted highlights how quickly conditions can change when economic pressures mount. While the current environment presents challenges, it also creates opportunities for those who understand the underlying drivers of value.

Investors are being reminded to focus on fundamentals rather than chasing recent performance. A well-located property with strong owner-occupier appeal, scarcity and long-term growth potential can make a meaningful difference to an investor’s long-term results, even amid broader market softness.

Looking ahead, the combination of demographic trends and constrained housing supply suggests that demand will remain supported over time. However, the immediate outlook reflects a market in transition, where patience and preparation may prove more valuable than urgency.
