Negative Equity Gaffe Hands Coalition Ammunition on Labor Housing Policy

What the Negative Equity Gaffe Was Actually About

A casual attempt to defend Labor's housing record has become a full-blown political fight over what negative equity actually means. Assistant Immigration Minister Matt Thistlethwaite said on Monday that because roughly 99 per cent of mortgage borrowers are meeting repayments or are ahead on their loans, those borrowers 'can't be in negative equity.'

The problem is that negative equity has nothing to do with repayment behaviour. A property is in negative equity when its current value is less than the outstanding mortgage balance. A borrower can be perfectly up to date on repayments and still owe more than the house is worth — a situation that bites when the owner needs to sell or refinance. Nationals leader Matt Canavan seized on the remarks on Tuesday as evidence that Labor lacks 'a basic understanding of how property works,' and used the moment to attack the government's capital gains tax overhaul.

The Coalition has also estimated that 34,000 borrowers who took out loans through Labor's 5 per cent deposit scheme are now in negative equity — a figure Canavan conceded is an estimate because there is no real-time data on individual house values. The government hit back: Acting Prime Minister Richard Marles said criticism 'overstates' the impact of the tax changes and predicted sustainable house price growth over the medium term, while Employment Minister Amanda Rishworth said less than 1 per cent of borrowers are 'facing any sense of negative equity.'

Negative Equity, the CGT Fight and the Numbers Neither Side Can Prove

Why Being Ahead on Repayments Does Not Rule Out Negative Equity

Thistlethwaite's argument conflated two separate risks. Meeting mortgage repayments is a cash-flow question — whether the borrower can service the loan. Negative equity is a balance-sheet question — whether the home's value still covers the debt. Making extra repayments lowers the balance, but it cannot guarantee that balance sits below the market value of the property. That is especially true for recent buyers who put down only a 5 per cent deposit: a 5 per cent cushion is wiped out by a roughly 5 per cent price fall, regardless of a flawless repayment record. The distinction is not academic. Negative equity becomes painful at the point of selling or refinancing, when the loan amount and the sale price have to settle against each other.

Canavan's Attack Is About More Than a Slip of the Tongue

The Nationals leader tied the gaffe directly to Labor's tax overhaul, which replaces the existing capital gains discount with an inflation-indexed model — a change Anthony Albanese had promised before the election not to make. The opposition's logic connects the two: if a minister cannot grasp the basics of how property works, the argument runs, then a tax design built on that misunderstanding should not be trusted, and falling confidence in the property market is the result. It is a political chain, but each link is independently real: the gaffe happened, the tax change is real, and prices are falling.

Two Numbers, Zero Real-Time Data

The factual core of the dispute is thinner than the rhetoric. The Coalition's 34,000 figure is explicitly an estimate — Canavan conceded there is no real-time data and no way to value every house. The government's counter-claim of under 1 per cent of borrowers facing negative equity is also stated without supporting detail in the article. The government's longer-term case, echoed by Marles and Rishworth, is that Treasury expects house prices to keep rising at a sustainable pace; the Coalition argues confidence is 'crashing very quickly.' Both can be true on different horizons, and neither is testable in the near term. That is precisely why the argument is being fought in politics rather than in data.

What Borrowers and Investors Should Watch in the Housing Fight

This is a policy fight with real money attached for two specific groups.

• Low-deposit borrowers: Recent buyers who used the 5 per cent deposit scheme are the most exposed if prices keep falling. Negative equity does not force a sale or trigger default, but it can block refinancing onto a cheaper rate and leave sellers owing money after a sale — the mechanism behind the Coalition's 34,000-borrower estimate, which remains an unconfirmed claim.
• Property investors: The tax treatment of a future sale depends on the final shape of the capital gains overhaul — an inflation-indexed model replacing the current discount. The decisive details are the legislative timeline and whether any amendments pass parliament before the change takes effect.
• Anyone tracking prices: The government promises 'sustainable growth' over the medium term and the Coalition says confidence is crashing. The verifiable inputs to watch are interest rate decisions and published house price data — the factors both sides, including Marles, cite as driving the current decline.
