Key takeaways
Australia's housing downturn is now effectively complete in its coverage; national values fell 1.1% in September for a sixth consecutive monthly decline, taking the cumulative drop since March to 5.2%, with every capital except Darwin falling over the quarter and 97% of capital city suburbs recording declines.
The mid-sized capitals have swung from monthly gains above 1% six months ago to monthly losses above 1% today, with Brisbane now posting the steepest fall of any capital at 1.5%, a reversal of more than two percentage points in monthly momentum inside half a year.
Advertised stock is 23.1% higher than a year ago despite new listings running 9.2% lower, because selling times have stretched from 23 days to 39 days, the inventory is building from properties that will not clear, not from vendors rushing to market.
Australia's housing downturn has stopped sparing anyone. Cotality's National House Price Index fell 1.1% in September 2026, the sixth consecutive monthly decline, bringing the cumulative drop since March to 5.2%.
Every capital city except Darwin recorded a fall over the September quarter, and 97% of capital city suburbs saw values decline across those three months.
The most telling detail is where the steepest fall came from. Brisbane, a market that spent two years as the national growth story, recorded the sharpest monthly decline of any capital at 1.5%, edging out Sydney's 1.4%.
Six months ago each of the mid-sized capitals was posting monthly gains above 1%. They are now losing more than 1% a month. That is a swing of over two percentage points in monthly momentum, and it happened inside half a year.
Sydney still leads the correction in cumulative terms, sitting 8.6% below its February peak, roughly $112,000 stripped from the median dwelling value.
Melbourne is 7.2% below its November cyclical high and 7.5% under the March 2022 record it has never reclaimed.
Regional Australia remains the one area holding comparative ground, with values up 5.6% year-on-year against a 1.8% decline across the combined capitals.
But that annual figure is backward-looking, regional prices have been trending down for four straight months now, and the gap is closing rather than widening.
National and Capital City Market Performance
The September quarter data shows a market where the question is no longer which cities are falling, but how fast each one is getting there.
Darwin stands alone as the sole capital still recording growth, and even there the pace has collapsed from 3.1% in the June quarter to half a percent in September.
| Capital City | Monthly Change (September) | Peak-to-Current | Key Metric & Status |
|---|---|---|---|
| Brisbane | -1.5% | -5.4% since May | Steepest monthly fall nationally; listings +55% YoY |
| Sydney | -1.4% | -8.6% since February | ~$112,000 off the median; quarter down 4.9% |
| Adelaide | -1.3% | -2.9% since May | 4th straight decline; 94% of suburbs lower |
| Perth | -1.2% | -6.0% since April | Still +10.1% annually; listings +60% YoY |
| Canberra | -1.1% | -6.2% since May 2022 | Quarter down 3.2%; listings ~15% above year ago |
| Melbourne | -0.7% | -7.5% since March 2022 | 10th straight decline but smallest since March |
| Hobart | -0.5% | -1.2% over the quarter | Sales up 2.3% YoY; listings 30% below 5-yr average |
| Darwin | +0.4% | +12% over the year | Only capital still rising; growth slowing sharply |

Why Stock Is Piling Up While Fewer People Sell
There is an apparent contradiction in the September figures that resolves into the clearest explanation of the entire downturn.
New listings across the capitals are 9.2% lower than a year ago.
Fewer vendors are coming to market, not more. And yet total advertised inventory is 23.1% higher. Both things are true simultaneously because the sales rate has fallen faster than the listings flow. Properties enter the market and simply stay there.
The time-on-market figure makes it concrete. Homes in capital cities now take an average of 39 days to sell, against 23 days a year ago. Nearly seventy percent longer. Multiply that across every listing and the inventory pile grows even as the inflow shrinks.
Transaction volumes confirm the demand collapse. National sales over the past three months were 19.1% below year-ago levels and 13.3% under the five-year average. Brisbane led the contraction at -27.2%, followed by Sydney at -26.5% and Perth at -24.2%.
Note: Lower turnover reaches well beyond housing, weaker transaction volumes flow directly into retail spending on furnishings and renovations, and into state government stamp duty revenue.
For buyers, this is theoretically the best environment in years: more choice, more time, more leverage. The constraint is not opportunity. It is that many prospective purchasers lack either the confidence or the borrowing capacity to act on it.
A Rental Market Finding Its Ceiling
For the first time in this cycle, the rental market is showing genuine signs of easing, though the relief arrives against a backdrop of affordability that has already been pushed past its limit.
The national vacancy rate climbed to 2.1% in September, up from February's record low of 1.5% and the highest reading since January 2025. It remains well under the pre-COVID decade average of 3.3%, but the direction has changed decisively.
What makes that shift notable is that it happened despite a sharp fall in investor activity, which would normally tighten rental supply rather than loosen it.
The likely explanation sits on the demand side. With weekly rents up roughly $200 over five years and rental affordability at the worst level ever recorded, tenants are restructuring how they live, consolidating into larger households, moving toward multi-generational arrangements, or taking smaller places further from the centre.
Monthly rent growth slowed to 0.3% in seasonally adjusted terms, the smallest monthly increase since May 2025. Annual growth now sits at 5.5%.
| Rental & Investment Metric | Current Status & Trends |
|---|---|
| National Vacancy Rate | 2.1% — highest since January 2025, up from 1.5% in February |
| Monthly Rent Growth | 0.3% — smallest monthly increase since May 2025 |
| Annual Rent Growth | 5.5% — slowing from the peak earlier this year |
| 5-Year Rent Increase | Approximately $200 per week above 2021 levels |
| National Gross Rental Yield | 3.85% — highest since August 2019 |
| Average Days on Market (Capitals) | 39 days — up from 23 days a year ago |

Gross rental yields nationally have recovered to 3.85%, the strongest since August 2019, and they are likely to keep climbing while rents rise and values fall.

But the yield number alone misleads.
New investors still struggle to reach neutral or positive cash flow once high interest costs are combined with rising insurance premiums, maintenance bills and property management fees.
The gross figure has improved considerably. The net position has not improved nearly as much.
The Rate Decision That Changes the Maths
The Reserve Bank has lifted the cash rate to its highest level in 15 years, and that single decision reshapes the outlook for everything discussed above.
The comparison to 15 years ago is instructive but incomplete.
Rates were last at this level in a very different household debt environment.
Australian borrowers today carry substantially more debt relative to income, which makes them far more sensitive to each increment of tightening. The same rate produces a materially larger effect than it did a decade and a half ago.
The practical consequences are immediate: reduced borrowing capacity, harder serviceability assessments, and heavier repayment burdens for existing mortgage holders.
And those costs are landing alongside rising living expenses and negative real income growth, narrowing both the pool of buyers who can qualify and the amount each of them can pay.
Tip: If you are buying in this market, the negotiating position is genuinely strong — 39-day selling times and 23% more stock mean vendors are far more willing to move on price than they were twelve months ago.
Affordability remains the binding constraint even as prices fall.
The improvement in purchasing power has been modest relative to the size of the preceding boom and the scale of mortgage rate increases.
Values are still high against household incomes, and the deposit hurdle remains substantial.
Deeply pessimistic consumer sentiment compounds this by delaying exactly the kind of high-commitment decision that buying a home represents.
The federal budget's tax changes add a further layer.
Less favourable negative gearing and capital gains tax settings have cut investor demand and weighed on confidence more broadly.
The policy intent is to redirect capital toward new construction, but the near-term effect has been a sharper fall in aggregate housing demand.
What Holds the Floor
Two forces are working against a deeper correction, and both are structural rather than cyclical.
The labour market remains reasonably stable. That stability underpins household income security and limits the risk of a meaningful rise in mortgage arrears or forced sales.
A sharper deterioration in employment would change the picture substantially, but there is no evidence of it yet.
New housing supply remains persistently inadequate. High construction and infrastructure costs, capacity constraints and difficult project economics continue to restrict completions.
Even where approvals and commencements improve, the long lead times mean any increase takes years to arrive as finished homes — which provides price support wherever advertised supply stays low.
The balance of risks has nonetheless shifted firmly to the downside.
Further value declines are the most likely outcome as high rates, constrained affordability and cautious sentiment continue to suppress demand.
How far this runs depends on three things: how long rates stay elevated, whether the labour market weakens materially, and how quickly consumer confidence begins to recover.
