According to REA Group, Australians are entering the property market with barely any financial buffer just as home values slide and mortgage arrears climb above their historical average — a combination that is amplifying the stress already visible in auction clearance rates across every state. That stress is not uniform: Randwick's 73.5% clearance rate sits 27.5 percentage points above Port Macquarie's 46%, a gap that defines the fracture running through Australia's spring 2026 property market. Against the RBA's unchanged 4.35% cash rate, the national auction data for September 2026 tells a story of credit-constrained buyers, selective bidding, and widening divergence between premium metropolitan suburbs and regional or outer-ring markets.
Cotality's Pain & Gain Report Sets the Macro Context
According to Property Update's coverage of the Cotality Pain & Gain report, Australia's current housing downturn has ended a recent run of record resale results. The share of profitable sales fell from a 21-year high, and the median gain retreated from its March 2026 peak. Cotality's analysis covered more than 94,000 residential resales in the June quarter, finding 95.4% delivered a nominal profit — still an elevated figure in absolute terms, but the directional shift is significant for vendors and agents planning campaigns this spring.
That retreating profitability is arriving simultaneously with a surge in low-deposit lending, a pairing that concentrates risk. Buyers who entered with minimal equity during the 2024–2025 price run are now sitting on thinner buffers as values soften. For auction markets specifically, this translates to more conditional bidders, fewer unconditional offers on the day, and vendors facing a harder choice between accepting lower bids or passing in and renegotiating. The clearance rate data across 20 surveyed suburbs in September 2026 reflects exactly this dynamic.
Randwick recorded a 73.5% auction clearance rate and a $2,400,000 median at 23 days on market, while Port Macquarie cleared just 46% of auctions at an $850,000 median over 48 days — a 27.5-point clearance gap and a 25-day difference in selling velocity between the two NSW markets.
The NSW Clearance Split: Randwick at 73.5%, Port Macquarie at 46%
Within New South Wales, the auction market is running at two speeds that bear almost no relationship to each other. Randwick's 73.5% clearance rate reflects sustained demand from owner-occupiers and investors in Sydney's eastern suburbs, where the $2,400,000 median has recorded 5.6% annual growth. At 23 days on market, stock is moving decisively. Surry Hills posts a similarly strong 73% clearance at a $1,920,000 median with 5.5% annual growth, confirming that inner-Sydney demand remains solid despite the broader credit tightening. Kirribilli adds a 72.5% clearance at $2,650,000 and 4.8% annual growth, rounding out a premium Sydney corridor that is holding its ground.
The picture deteriorates sharply once you move beyond the metropolitan core. Port Macquarie's 46% clearance rate at 48 days on market represents genuine buyer withdrawal — nearly half of properties going to auction are failing to sell under the hammer. Ballina at 47% clearance and 45 days on market confirms this is a regional NSW pattern, not a single-suburb anomaly. Liverpool at 60.5% and Penrith at 62% sit in the middle range, reflecting outer-suburban Sydney markets where first-home buyer demand has softened under the weight of the 4.35% cash rate but not collapsed entirely. For agents operating in regional NSW, the data points to a necessary recalibration of vendor price expectations before auctions are scheduled.
Victoria: Toorak at 72% vs Dandenong at 56% — The Intrastate Gap
Victoria's auction market shows its own internal divide. Toorak records a 72% clearance rate at a $2,800,000 median with 4.5% annual growth and just 23 days on market — performance that reflects a buyer pool insulated from rate sensitivity by equity and income levels. Kew at 71% clearance and Prahran at 69% complete a premium Melbourne band where clearance rates remain well above the state average. These suburbs are attracting buyers who can move without conditional finance clauses, giving vendors confidence to proceed to auction rather than private treaty.
Dandenong's 56% clearance rate at a $680,000 median tells a structurally different story. At 40 days on market and 2.3% annual growth — the weakest in the dataset — Dandenong reflects a market where low-deposit buyers face the sharpest affordability pressure. Reservoir at 62% clearance and Newtown (VIC) at 52% confirm that Melbourne's outer and middle rings are clearing auctions at rates that should prompt agents to model realistic reserve prices rather than relying on competitive bidding dynamics. The Newtown figure of 52% is the second-lowest in the entire 20-suburb dataset, exceeded only by Port Macquarie and Ballina.
Western Australia and Queensland: The Clearance Rate Anomaly
Western Australia's auction market operates under a different set of conditions — historically lower auction volumes and a strong price growth cycle that is compressing days on market and supporting clearance rates. Nedlands posts a 65.5% clearance rate at a $2,200,000 median with 15% annual growth and just 15 days on market, the fastest sales cycle in the dataset. South Perth records 63.5% clearance at $1,450,000 with 13.8% annual growth and 17 days on market. Fremantle at 54.6% and Mandurah at 56% represent WA's more accessible price points, where clearance rates remain moderate but days on market stay well below east-coast equivalents. For macro and interest rate market analysis, WA's insulation from the broader downturn reflects a local supply constraint and interstate migration dynamic that eastern-state markets are not replicating.
Queensland's clearance rates are softer than WA's premium suburbs but outperform Victoria's outer ring. West End clears at 62% at a $1,350,000 median with 8.8% annual growth and just 22 days on market. Indooroopilly matches at 62.5% clearance and $1,380,000 median with 8.5% annual growth. Maroochydore on the Sunshine Coast records 54% clearance at $1,050,000, reflecting a market where strong growth (8.5% annually) is attracting buyers but auction clearance has not yet caught up to the price momentum. For Queensland, private treaty remains the dominant sales method outside Brisbane's inner ring, which means clearance rates understate actual market depth compared with Sydney or Melbourne.
Low-Deposit Lending and Negative Equity Risk: What the Clearance Data Confirms
The REA Group report on surging low-deposit lending connects directly to the clearance rate divergence across these 20 suburbs. Buyers entering at minimal deposit levels are concentrated in markets below the $1,000,000 price point — Port Macquarie ($850,000), Dandenong ($680,000), Mandurah ($550,000), Liverpool ($850,000), and Penrith ($880,000). These are precisely the suburbs where clearance rates are weakest or auction volumes are thinnest. As mortgage arrears climb above their historical average, the cohort most exposed to rate stress is also the cohort underpinning demand in markets that are already clearing at 46%–62%.
For vendors in these markets, the practical consequence is a higher probability of passing in at auction and entering post-auction negotiation. Agents should be pricing campaigns with that outcome modelled from the start, rather than relying on competitive bidding to achieve the reserve. The Cotality Pain & Gain data reinforces this point: the retreating median resale gain signals that the vendor who set their reserve based on 2025 peak comparable sales may find the current market unwilling to meet that expectation. Strategic use of Technology for Property Investors — Managing Your Portfolio Remotely — particularly comparable sales tracking and market monitoring tools — is increasingly relevant for investors managing multi-property portfolios across these diverging market conditions.
What the September 2026 Clearance Data Signals for Agents, Buyers, and Vendors
The 27.5-point clearance gap between Randwick and Port Macquarie is not a temporary distortion — it reflects structural demand differences amplified by the 4.35% cash rate. Premium metropolitan suburbs with deep buyer pools and high equity-rich purchasers are sustaining clearance rates above 70%. Regional and outer-ring markets, where low-deposit lending has concentrated entry-level buyers, are posting clearance rates that make private treaty campaigns a more reliable path to unconditional sale. Agents in the 46%–56% clearance band should be recommending shorter auction campaigns with conservative reserve settings, or pivoting to private treaty with vendor price guidance anchored to current comparable sales rather than peak-cycle benchmarks.
For buyers, the data identifies genuine opportunity in markets where clearance rates signal vendor flexibility. Port Macquarie at 48 days on market and 46% clearance, Ballina at 45 days and 47% clearance, and Newtown (VIC) at 52% clearance all point to conditions where post-auction negotiation is common and reserve prices may be adjusted. For investors tracking the relationship between clearance rates and resale profitability — the core tension in Cotality's June quarter report — the suburbs posting sub-60% clearance rates and rising days on market are the ones where the Pain & Gain balance is most likely to deteriorate further into the December quarter if the RBA holds at 4.35%.
