Anthony Albanese and Jim Chalmers wanted their housing reforms to give younger Australians a better chance of owning a home. Instead, they are entering a far more dangerous political phase: property prices are falling across most of the country, investors are retreating and affordability remains painfully weak because mortgage rates are still high.

That combination has created an uncomfortable argument for the Albanese government to answer.

Labor says it is correcting a housing system that has increasingly favoured existing property investors over aspiring homeowners. Critics say the government has weakened confidence in the country’s biggest household asset at exactly the wrong moment.

The latest housing data give both sides something to point to.

National dwelling values fell another 0.9 per cent in August, according to data cited by Commonwealth Bank economists, marking a fifth consecutive monthly decline and leaving values 3.6 per cent below their March peak on that measure.

About 93 per cent of Australian suburbs recorded falling values during the month.

Sydney remains at the centre of the correction. Prices fell 1.4 per cent in August and were 7.1 per cent below their February peak, while Melbourne fell another 1.1 per cent and was 6.5 per cent below its previous high.

CommBank now expects national dwelling prices to fall about 9 per cent from peak to trough during the current cycle. Its forecasts point to declines of roughly 13 per cent in Sydney and 12 per cent in Melbourne, with Brisbane, Perth and Adelaide also expected to suffer corrections of about 8 per cent.

The bank has described the adjustment as both faster and more widespread than it previously expected.

Other property indices measure the market slightly differently, but they tell the same broad story. PropTrack recorded national home prices falling 0.2 per cent in August, also the fifth consecutive monthly decline, leaving prices 2.7 per cent below their March peak.

Those numbers are politically awkward for a government that introduced its most significant housing tax changes in decades just months ago.

In the May Budget, Labor announced that negative gearing for residential property would be restricted to new builds from the 2027–28 income year.

Existing investments acquired before 7.30pm on Budget night, May 12, are protected under grandfathering arrangements. But investors purchasing established residential property after that time face different treatment once the reforms commence: rental losses will no longer be deductible against unrelated income such as wages, although losses can still be offset against residential property income and carried forward.

The government also moved to replace the longstanding 50 per cent capital gains tax discount with inflation-adjusted indexation for gains accruing from July 1, 2027, alongside a minimum 30 per cent tax rate on realised real capital gains. New housing receives more favourable treatment under the reforms as Labor tries to steer investment towards additional supply.

The government’s argument is straightforward.

More than 80 per cent of new investor lending has been flowing into existing homes rather than creating new dwellings. Labor says tax concessions that encourage investors to compete with first-home buyers for the same established houses have contributed to prices growing much faster than incomes.

Chalmers told Parliament that Australian house prices had increased by more than 400 per cent since 1999, more than twice the pace of average earnings.

Treasury estimates Labor’s reforms will allow around 75,000 additional Australians to become homeowners during the next decade.

The government therefore argues that some moderation in prices is not necessarily a policy failure if it improves access to ownership.

But there is a substantial difference between moderating price growth and presiding over a sharp national downturn.

At Budget time, Treasury modelling suggested house prices would still grow over the following couple of years, but by about 2 per cent less than they otherwise would have.

On that basis, the government was not forecasting a property crash. It was expecting prices to keep rising, only more slowly.

That assumption is now being tested.

Asked this week whether Treasury had underestimated the effect of Labor’s reforms, Chalmers said it was important to compare the same time periods.

He noted that Treasury’s estimate covered the next couple of years rather than the first few months after the Budget and pointed out that even CommBank expects house prices to begin recovering during 2027.

“There is softness in the housing market,” Chalmers acknowledged in an ABC interview, while stressing that the downturn began before the Budget.

That is an important qualification because the federal tax changes are not the only major force bearing down on Australian property.

The Reserve Bank has increased the cash rate three times during 2026 and was holding it at 4.35 per cent after its August meeting.

Higher interest rates have reduced borrowing capacity, increased repayments for existing borrowers and made investment property less attractive even before the full tax changes take effect.

They have also produced a paradox for aspiring homeowners.

A cheaper house is not automatically a more affordable house.

The latest realestate.com.au Housing Affordability Report found that a typical Australian household earning about $125,000 could afford only 12 per cent of homes sold during the 2026 financial year.

That was the lowest result recorded by the affordability index and below the previous low of 14 per cent during the 2008 financial year.

Five years earlier, when mortgage rates were dramatically lower, the same median-income household could afford 43 per cent of homes sold.

For lower-income households, home ownership is even further out of reach. A household around the 30th income percentile could afford just 2 per cent of properties sold.

That is the political trap for Labor.

If prices fall but interest rates remain high, young Australians may still be unable to borrow enough to buy. At the same time, existing homeowners watch the value of what is often their largest asset decline.

Labor could therefore end up angering owners without delivering an immediate affordability breakthrough for buyers.

The lending data also show a market losing momentum.

Australian Bureau of Statistics figures for the June quarter showed the number of new housing loan commitments falling 5.4 per cent, while their value declined 5.2 per cent.

Investor lending was especially weak. The number of new investor loan commitments dropped 8.6 per cent during the quarter and their value fell 10.2 per cent.

CommBank has since reported an even sharper pullback in applications following the Budget, with investor activity particularly affected.

For critics such as commentator Steve Price, this amounts to a profound political miscalculation.

Price argues that Albanese and Chalmers cannot simultaneously sell falling prices as good news for young buyers while expecting millions of homeowners to accept large reductions in household wealth without political consequences.

He characterises the downturn as a potential electoral nightmare for Labor and draws comparisons with the Hawke-Keating government’s decision to restrict negative gearing between 1985 and 1987.

There is, however, an important historical qualification to that comparison.

Negative gearing restrictions introduced in 1985 were reversed in 1987, and the period is frequently cited by opponents of reform as proof that changing the concession sends rents soaring.

But parliamentary analysis of the episode found that real rents did not rise nationally during that period.

They increased significantly in Sydney and Perth, where vacancy rates were relatively tight, while remaining broadly flat or falling in several other capital cities.

That history does not prove Labor’s current reforms will succeed. It does show that the simple claim that restricting negative gearing automatically caused a nationwide rent explosion in the 1980s is not supported by the national data.

The same caution is necessary when analysing the current downturn.

Labor’s reforms can influence investor behaviour before their formal start dates because buyers make investment decisions based on the tax rules they expect to face in future years.

Chalmers himself has now acknowledged that the reforms are one factor affecting housing prices.

But blaming the entire correction on Labor would ignore the effect of interest rates, reduced borrowing capacity, weaker confidence and broader economic uncertainty.

The economy itself is growing only modestly.

Australian Bureau of Statistics figures released this week showed GDP expanding 0.4 per cent in the June quarter and 2.1 per cent over the year. Household spending remained cautious, while private business investment declined 0.5 per cent during the quarter.

A housing correction can feed back into that environment.

When property values fall, households can feel less wealthy and become more reluctant to spend. Construction and real estate activity can weaken. Developers can find projects harder to finance. At the same time, prospective buyers may delay purchases because they expect prices to fall further.

That last factor is particularly troublesome for a government seeking to increase home ownership.

A first-home buyer who believes a $900,000 property might be worth $850,000 several months later has an incentive to wait, even if the original price is already lower than it was last year.

The government’s longer-term answer remains housing supply.

Labor says its tax reforms are deliberately designed to favour new construction, allowing investors in new builds to retain access to negative gearing and more favourable CGT choices.

The theory is that investor money should help create additional homes rather than simply bid up the price of existing ones.

Whether that happens at sufficient scale will be critical.

Australia is already struggling with expensive construction, labour shortages, planning delays and financing costs. If investor participation in new housing does not increase enough to compensate for reduced activity elsewhere, critics will argue the tax overhaul has weakened supply rather than strengthened it.

There is also a deeper political dilemma that no Treasury model can resolve.

Australia has spent decades treating rising house prices as both a social problem and a measure of household prosperity.

Young Australians locked out of ownership want prices to become more attainable. Existing owners generally do not want their homes to lose substantial value. Renters need more supply, while investors need sufficient returns to keep providing rental accommodation.

No government can satisfy all those interests simultaneously.

Labor has chosen to intervene more aggressively than its predecessors, arguing that the status quo had become fundamentally unfair to younger generations.

That choice means Albanese and Chalmers now own more of the political consequences as well.

If the market stabilises, borrowing costs eventually fall and first-home ownership begins rising, Labor will argue that the temporary pain was part of resetting a badly distorted system.

If prices continue falling sharply, rental supply deteriorates and young buyers remain locked out because mortgage rates stay high, the government will face a much harsher verdict.

The next year will therefore determine whether Labor’s housing reforms are remembered as a difficult correction to an unsustainable market — or as an intervention that delivered the political nightmare its critics now predict.
