Cotality's October Housing Chart Pack puts an estimated 39,747 homes sold nationally in September, a fall of more than 20% against the same period last year, with capital city vendors accepting their largest discounts in five years. According to Property Update, selling times have blown out to more than five weeks as spring's usual momentum fails to materialise. The stall is splitting auction markets sharply: Kirribilli's 72.5% clearance rate sits roughly 25 points above Ballina's 47%, a gap that now determines which sale method agents are recommending to vendors.
Auction Clearance Rates Diverge Across the Price Spectrum
At the premium end, the auction system is still converting. Randwick posted a 73.5% clearance rate with a median of $2.4 million and just 23 days on market, while Surry Hills cleared 73% in 23 days and Kirribilli 72.5% in 24 days. Toorak, in Victoria's blue-chip corridor, held a 72% clearance rate at 23 days on market despite annual growth of only 4.5%. These figures suggest that in established, high-demand inner-ring suburbs, the on-the-day auction format continues to compress negotiation and deliver certainty for sellers even as the broader market slows.
The picture inverts in regional and coastal NSW. Port Macquarie's auction clearance rate sits at 46% with a 48-day median selling cycle, and Ballina trails at 47% clearance across 45 days on market. Maroochydore, despite 8.5% annual growth, cleared only 54% of auction listings over 28 days. These are precisely the conditions Cotality's chart pack flags nationally — vendors in softer markets are being forced into price reductions after failed auction campaigns, then settling via negotiated private treaty terms below their original reserve expectations.
Private Treaty Becomes the Default as Days on Market Blow Out
Cotality's finding that national selling times now exceed five weeks lines up closely with the mid-tier suburb data. Dandenong sits at 40 days on market with a 56% clearance rate, Liverpool at 38 days with 60.5%, and Newtown and Penrith both at 35 days with clearance rates of 52% and 62% respectively. None of these are catastrophic numbers in isolation, but stacked against last year's tighter cycles they confirm the pattern Property Update describes: auctions are increasingly a first step rather than a final outcome, with private treaty negotiation closing the gap after passed-in results.
The shift is compounding other structural changes in buyer behaviour. According to REA Group, nearly four in five NSW first home buyer purchases are now apartments as house sales plunge and tax reforms loom, pushing demand toward Western Sydney and regional centres such as Dubbo. For vendors in slower-clearing house markets like Port Macquarie and Ballina, that demand migration away from freestanding houses adds further pressure to accept negotiated outcomes rather than hold out for auction-day competition. Vendors weighing whether to persist with an auction campaign or pivot early are better served reviewing Vendor Advocacy — Do You Need One? before relisting.
Agent Performance Signal: What the Clearance-Days Matrix Reveals
Western Australia's sample suburbs tell a different story again. Nedlands cleared 65.5% of auction listings in a median of just 15 days, South Perth matched a 63.5% clearance rate across 17 days, and Fremantle and Mandurah both sat in the mid-50s on clearance with 24 to 25-day cycles. None of these clearance rates match Sydney's premium-tier suburbs, yet the speed to transaction is markedly faster — a signal that agent pricing discipline and buyer urgency in WA's current cycle are outpacing the east coast.
Western Australia's sample suburbs cleared in 15 to 25 days on average, while Port Macquarie and Ballina in NSW each exceeded six weeks on market — a 30-day-plus gap wide enough to reshape which sale method agents recommend to vendors in each state.
That divergence is a direct agent-performance question, not just a market-condition one. An agent quoting a 46% clearance-rate suburb needs a materially different vendor conversation — on reserve setting, campaign length, and fallback strategy — than one operating in a 70%-plus suburb where auction day still does the heavy lifting. Measuring that difference consistently requires looking past the headline clearance figure to days on market and vendor discounting together.
Background: Measuring Agent Performance in a Stalling Market
Assessing whether an agent is genuinely outperforming their local benchmark, rather than simply operating in a hot suburb, means tracking clearance rate, days on market and vendor discount together against comparable listings — the approach detailed in How to Measure Real Estate Agent Performance. In a market where Cotality is recording the largest capital city discounts in five years, that benchmarking matters more than usual, because a 60% clearance rate in a falling market may represent stronger relative performance than the same figure did twelve months ago.
For vendors in suburbs sitting below 50% clearance, auction is no longer the automatic default. Some are shifting toward off-market sales to avoid publicly recording a passed-in result, while others renegotiate terms through extended private treaty campaigns. Set against the slower selling environment Cotality describes domestically, it's a pattern also visible in international property market comparison, where auction-dependent markets tend to see the sharpest method shifts whenever buyer demand softens.
The near-term signal for agents, vendors and buyers is consistent across the data: clearance rate alone no longer tells the full story. With the cash rate at 4.60% and Cotality recording a 20%-plus fall in September sales nationally, agents operating in sub-55% clearance suburbs should be pricing campaigns around realistic private treaty timelines rather than banking on auction-day competition, while vendors in suburbs like Randwick, Surry Hills and Kirribilli retain more leverage to hold firm on reserve. Buyers, meanwhile, have the clearest negotiating window in years in the slower-clearing regional and outer-metro markets this data identifies.
