Australia Abolishes Negative Gearing Tax Benefits as Property Auction Clearance Rates Fall Below 50%
N.R. Finch
Australia's Labor government announced the end of negative gearing and the capital-gains tax discount in May. Within a month, the national auction clearance rate fell below 50% — the lowest since the pandemic — as investors pulled back en masse, with economists forecasting house prices could decline through 2027.
What exactly changed in the tax code?
Two core moves: the capital-gains tax (CGT) discount will be abolished from July 2027, and negative gearing — a rule that lets property investors offset rental losses against their personal income tax — will no longer apply to existing residential holdings.
This means → the two biggest tax incentives for property investment disappear at the same time: no deduction on the way in, no discount on the way out.
The changes directly affect more than 2 million investment-property owners — roughly 10% of Australia's working-age population.
How cold has the auction market gone?
Cotality data show the national weekend auction clearance rate dropped below 50% within a month of the announcement — the lowest since the pandemic. In plain terms = more than half of all listed properties failed to attract a single bid at auction.
Brisbane Ray White agent Avi Khan reported that both open-home attendance and bidder numbers halved, with clearance rates falling to around 30%–35%.
A five-bedroom house near Sydney's Bondi Beach, listed at A$5.2 million (≈US$3.64 million), drew zero bids. Auctioneer Clarence White said "everyone in the market is sitting on the sidelines."
What are investors doing?
Sydney investor Kellie Adamson holds two properties worth a combined A$3 million. She says the reform has "completely changed" her buying strategy; she is now considering markets outside Sydney or even commercial property.
Queensland investor Shaun Craike estimates his 10-property, ~A$6 million portfolio has lost roughly A$500,000 in value since the announcement.
This reflects a collective freeze rather than a panic sell-off — the reforms do not apply retroactively, but they have shut down new buying intent.
Whose path into the market just closed?
About 6,500 "rentvestors" each year — first-home buyers who purchase an investment property, rent elsewhere, and claim negative-gearing deductions — rely on this route to enter the market. The reform blocks it.
AJ Clores, a 27-year-old Sydney rentvestor with a A$3.2 million portfolio, says he will not expand any time soon: "Probably not until 2028, and even then I won't rush."
This means → the market structure is tilting from "investor-led" to "owner-occupier-led" — but owner-occupier demand cannot fill the gap left by retreating investors in the short term.
How far could prices fall, and for how long?
SQM Research forecasts Sydney prices could drop up to 9% in 2026, Melbourne up to 7%. Economists broadly expect a 5%–10% national decline over the next year.
SQM Research managing director Louis Christopher says this downturn "will very likely extend into 2027."
In plain terms = auction cooling plus rising interest rates leave no near-term floor in sight. The actual pace of market clearing before the CGT discount formally expires in 2027 will be the key test of whether this is a cyclical correction or a structural shift.
What does this mean for ordinary households?
AMP data show roughly 70% of Australian household wealth is tied to residential property values.
This means → falling house prices are not just paper losses for investors — they directly shrink most families' balance sheets and, in turn, weigh on consumer confidence.
Byron Bay Sotheby's agent Nick Gill called it "the biggest market correction I have ever seen" — a judgment from a practitioner, not an analyst, reflecting ground-level sentiment.
