According to The Age, the national auction premium gap has narrowed slightly from historical peaks. The story behind the shrinking premium is a familiar one — fewer bidders, more cautious vendors, and a market still working through the aftermath of successive rate hikes.
Why the Auction Premium Is Shrinking
"When you have less competition, the gap narrows," she said, adding that buyers currently have time and significantly less competition than in previous years.
This matters because the auction premium has traditionally been the clearest signal of how much competitive tension exists in a market. When bidders are scarce, vendors lose the leverage that made "testing the market" worthwhile.
For sellers weighing their options heading into the spring selling season, the practical read is this: an auction still beats accepting an early offer on average, but the margin for error has shrunk. A buyer's agent can help vendors and purchasers alike read these signals more accurately before committing to a sale method.
The Hidden Cost Sellers and Landlords Both Face
A narrower auction premium is one risk. A far more severe one sits with landlords who never anticipated what a tenant could do to a property before it ever reaches market. A separate case reported by realestate.com.au describes a Sunbury property owner, Jacob Cheu, who leased his fringe-Melbourne acreage to a tenant who allegedly used it as an illegal dump site, leaving an estimated 5500 tonnes of waste, including asbestos, and a clean-up bill feared to reach $2 million. Complete the sentence accurately based on source: a nearby Diggers Rest landowner, 71-year-old Suji An, faced an almost identical scheme, with her property allegedly covered in nearly 4000 cubic metres of industrial waste and clean-up quotes ranging from $600,000 to $2 million.
A property sitting unsold for weeks loses value, and a property occupied by the wrong tenant can lose far more — the gap between a narrowing 8.9 per cent auction premium and a $2 million environmental clean-up bill shows two very different scales of risk facing Australian property owners this spring.
Victoria's Environment Protection Authority confirmed it is ramping up inspections and enforcement against illegal waste dumping, warning that landlords "may be liable if a tenant leaves behind an environmental hazard and either abandons a site or cannot meet the costs themselves." This is the uncomfortable reality for owners of fringe and acreage properties: Australian law can place the clean-up obligation squarely on the landlord, regardless of fault, and few standard landlord insurance policies are built to absorb a seven-figure environmental liability triggered by a tenant's deliberate misconduct.
What This Means for Landlord Insurance Coverage
Standard landlord insurance policies are generally designed around rent default, malicious damage by a tenant, and loss of rent — not industrial-scale illegal dumping or asbestos contamination requiring six- or seven-figure remediation. The Sunbury and Diggers Rest cases both involve acreage and fringe properties, precisely the kind of asset where rural or semi-rural landlords may assume standard metro-style cover applies without checking exclusions around environmental hazards, pollution, or waste deposited by a third party. For an investor holding acreage near Melbourne's growth corridors, the gap between what a policy actually covers and what a tenant can inflict has rarely been starker.
The mechanism here is straightforward but brutal. A tenant who presents convincingly — as Cheu's did, bringing a child along and claiming the land was needed for horses — can pass every informal screening check a private landlord runs. Once the lease is signed, the landlord's legal exposure to what happens on the property is immediate, and insurers typically treat pollution or contamination events as exclusions or sub-limits rather than full-cover events. This is why property investors financing acreage or fringe holdings need to understand their Property Insurance Guide exclusions before settlement, not after a tenant has moved in.
Borrowers financing these purchases should also think about how they structure their loan facilities, since a sudden six-figure liability changes the calculus around available equity. Understanding the difference between an offset account and a redraw facility becomes relevant here — an offset account keeps funds accessible and separate from the loan itself, which matters if an owner suddenly needs liquidity for legal costs or an EPA-ordered clean-up, whereas redraw funds are tied directly to the loan structure and access can be restricted by the lender at the worst possible moment.

Practical Steps for Vendors, Landlords and Buyers
For vendors deciding between auction and private treaty this spring, the data says auction still wins on price for the right property, but the margin has narrowed from Melbourne's 8.9 per cent down from a 13.3 per cent peak, and Sydney's 8.1 per cent down from 11.5 per cent. A property unlikely to draw three or four genuine bidders in a four-week window is a weaker auction candidate today than it was during the 2021-22 peak, and vendors who have already bought their next home should weigh any reasonable pre-auction offer seriously rather than risk a failed auction day.
For landlords, particularly those holding acreage or fringe-suburb property, the Sunbury and Diggers Rest cases are a reminder to scrutinise tenant screening and insurance exclusions before signing a lease, not after. Victoria's Environment Protection Authority has warned that landlords should be alert to tenants who misrepresent their purpose for renting property.
Buyers inspecting properties this spring should also factor in how long a listing has been sitting unsold — Conisbee noted that properties on market for longer periods tend to lose value and days on market are increasing "quite dramatically." A longer selling window can sometimes reflect pricing mismatches, but it can equally reflect underlying property issues worth investigating before making an offer, particularly on fringe or acreage listings where land use history matters.
