Key takeaways
Perth recorded its fourth consecutive monthly decline in August, falling 0.8% to sit 3.2% below the April peak — a $33,370 reduction in the median dwelling value, though prices remain 80% higher than five years ago, or roughly $445,000 above 2021 levels.
Winter home sales collapsed 23% year-on-year, the steepest transaction contraction of any capital city, driving advertised listings 51% above year-ago levels and dismantling the extreme scarcity that had underpinned Perth's five-year run.
The boom was built on empty shelves rather than deep demand, which is why the reversal came so quickly — and with core inflation surprising to the upside and population growth normalising after the post-pandemic surge, the supports that carried Perth through the national downturn have largely dissolved.
Perth has now been falling for four consecutive months. August delivered a further 0.8% decline, leaving the market 3.2% below its April peak and taking $33,370 off the median dwelling value since the turn began.
For a market that spent five years as the most spectacular performer in the country, that is a strange sentence to write. And the context makes it stranger still: Perth values remain 80% higher than five years ago — roughly $445,000 added to the median. The four-month decline has clawed back less than 8% of what the boom delivered.
What has genuinely shifted is the demand picture. Winter home sales fell 23% compared to the same period last year — the sharpest transaction contraction of any capital city in the country. And with buyers stepping back at that scale, advertised listings have climbed 51% above year-ago levels, a supply reversal matched only by Brisbane.
Perth spent the boom years as the market where nothing was available and everything sold. The scarcity was so extreme that even modest buyer interest produced compounding price growth. That mechanism has now run in reverse — not because sellers flooded in, but because the buyers who sustained it simply stopped showing up.
Perth Market Performance
Perth's monthly decline sits in the milder half of the national spread, matching Adelaide at 0.8% and running well behind Sydney's 1.8%. The severity is in the volume data, where Perth leads the country in transaction collapse.

|---|---|---|
| Monthly Change (August) | -0.8% | 4th consecutive monthly decline |
| Decline Since April Peak | -3.2% | $33,370 removed from the median dwelling value |

A Boom That Ran on Empty Shelves
Understanding Perth's current position requires being honest about what actually drove the previous five years, because the two are directly connected.
Perth's 80% gain was not primarily a demand story. It was a supply story. Listings sat so far below any reasonable historical benchmark that the small pool of active buyers had almost nothing to choose from, and prices climbed accordingly. The market was priced on scarcity — and scarcity is the most fragile foundation a housing market can have.
When buyers withdrew, that foundation gave way immediately. Sales down 23% year-on-year meant properties stopped clearing at the rate that had kept the listings pool artificially thin. Stock accumulated. Within months, the market moved from acute shortage to 51% more listings than a year ago — and the pricing power that had sat entirely with vendors transferred to the other side of the table.
Note: Perth's 23% collapse in winter sales volumes is the steepest of any capital city — the supply buildup here is entirely a demand failure, not a seller exodus.
Nationally, the same broadening is unmistakable. 93% of capital city suburbs recorded value declines over the past three months, compared with 45% in autumn. The gap between premium and affordable segments has narrowed as affordability pressure spreads more evenly, and even regional Western Australia — a standout performer through most of this cycle — has joined the winter decline.

The Widening Gap Between What Tenants Pay and What Owners Earn
Perth's rental market carries a particular sting for tenants who watched the boom price them out of ownership and are now watching rents chase them anyway.
The national vacancy rate lifted to 1.9% in August — the highest since January 2025, up from the record low of 1.5% recorded in February. Some easing, then. But the pre-COVID decade average was 3.3%, and the national rate has barely moved above 2% since early 2022. At current levels the market still applies upward pressure on rents rather than releasing it.
Rents rose 0.4% in seasonally adjusted terms in August, in line with July and the two-year monthly average. Annual growth of 5.7% has added roughly $38 per week to the national median, while the five-year picture shows a 39% increase — around $200 more per week than tenants paid in 2021.
| Rental & Investment Metric | Current Status & Trends |
|---|---|
| National Vacancy Rate | 1.9% — highest since January 2025, still well below 3.3% pre-COVID average |
| Annual Rental Growth | 5.7% — adding ~$38 per week to the national median |
| 5-Year Rent Increase | 39% — approximately $200 per week above 2021 levels |
| National Gross Rental Yield | 3.79% — highest since September 2019 |
| New Listings (National) | -6% vs. year ago; 8% below the 5-year average |
| Quarterly Sales Volumes (National) | -15% year-on-year; 11% below the 5-year average |

Gross rental yields nationally have reached 3.79%, the strongest reading since September 2019. Perth has historically carried yields above the national figure, and the combination of rising rents and falling values has pushed them higher still. Yet even at these levels, the arithmetic does not work for most leveraged investors — the gap to neutral cash flow remains wide, and with core inflation surprising to the upside, borrowing costs may not have finished rising.
Perth's Spring Reckoning
The demand pressures that have been accumulating since late last year are hardening as Perth moves into spring. Affordability and serviceability constraints remain acute despite lower prices delivering modest improvement at the edges. High mortgage rates and constrained borrowing capacity continue to hold buyers back.
The inflation surprise carries real weight here. Core inflation came in higher than expected, lifting the probability of further Reserve Bank tightening. Another rate rise against Perth's household debt levels would reduce borrowing capacity further, add to the burden on existing mortgage holders, and undermine consumer confidence that has recovered only slightly from January lows.
Real wages have now fallen for four consecutive quarters, making deposits harder to accumulate at precisely the moment falling prices would otherwise improve access. Population growth has normalised after the post-pandemic surge — and for Perth, which benefited enormously from interstate migration during the boom, that removal of demand support is particularly consequential.
Tip: Perth's median has fallen $33,370 since April while listings climbed 51% — buyers who spent the boom years watching properties sell before inspections now face a market with genuine choice and vendors prepared to negotiate.
Structural limits on the decline remain in place. New housing supply is still insufficient against underlying demand, with construction costs and capacity constraints restricting completions. Low unemployment should keep forced sales and mass defaults off the table — and Perth's 80% five-year gain means the equity buffers protecting local owners are among the deepest in the country. First home buyer incentives, including the 5% deposit scheme, should support the affordable end.
Spring functions as the genuine test. Listings typically rise seasonally through spring and early summer, and Perth enters that window with stock already 51% above year-ago levels and sales volumes down 23%. If the seasonal increase arrives without buyers returning to absorb it, the four-month decline will likely extend well into the second half of the year.
