Rising debt, mortgage stress and cost-of-living pressures are exposing cracks in the Australian economy
Australian households are carrying some of the highest debt burdens in the developed world, and the pressure is beginning to show.
For more than two decades, Australia’s economic model has been heavily supported by rising residential property values, expanding household credit and historically low interest rates. That system worked while wages were growing, rates were low and asset prices kept climbing. But the environment has changed.
Today, households are facing a combination of elevated interest rates, persistent living-cost pressures, high rents, insurance increases and slowing discretionary spending. While Australia has not yet experienced the type of widespread consumer delinquency currently being seen in parts of the United States, the underlying stress indicators are clearly moving in the wrong direction.
According to the Reserve Bank of Australia (RBA), household indebtedness remains a key structural vulnerability within the Australian financial system. The RBA noted in its March 2026 Financial Stability Review that high debt levels continue to leave many borrowers exposed to economic shocks and changes in employment conditions.
Australia’s banking regulator, APRA, has now gone so far as to introduce formal debt-to-income (DTI) lending limits for residential mortgages — a significant step that highlights growing concern around highly leveraged borrowing. From February 2026, lenders have been restricted so that no more than 20 per cent of new home lending can be written to borrowers with debt levels exceeding six times household income.
That is not a move regulators make when everything is healthy.
Mortgage Stress Is Rising Across Australia
One of the clearest warning signs is the increase in mortgage stress.
Roy Morgan data released in April 2026 estimated that approximately 1.45 million Australian mortgage holders were considered “at risk” of mortgage stress, representing 26.8 per cent of mortgage holders nationally.
Separate reporting by the ABC suggested that if rates were to rise further, more than 1.6 million Australians could fall into mortgage stress territory.
While official mortgage arrears in Australia remain relatively low by international standards, they have been steadily increasing from the record lows experienced during the pandemic era.
CoreLogic data previously showed mortgage arrears rising to approximately 1.6 per cent during 2024 — the highest level reported since 2021.
The RBA has repeatedly highlighted that arrears remain concentrated among:
• Highly leveraged borrowers
• Lower income households
• Recent purchasers who borrowed near peak valuations
• Borrowers with high loan-to-income ratios
This is particularly important because Australia’s housing market remains one of the most expensive in the world relative to household income.
In Sydney and Melbourne especially, mortgage repayments are now consuming historically elevated proportions of disposable income for many households.
The Australian Consumer Is Starting To Crack
There is also growing evidence that Australian consumers are beginning to pull back.
Retail spending growth has softened materially over the past 18 months, discretionary spending categories have weakened and insolvencies across parts of the small business sector, particularly hospitality and construction, remain elevated.
The RBA acknowledged in its Financial Stability Review that company insolvencies remain above normal levels in several pressured sectors of the economy.
At the same time, demand for consumer credit has continued to rise.
ABS finance and wealth data has previously shown that average household debt levels in Australia remain extremely high, while more recent lending data indicates that household borrowing demand has continued to increase despite elevated rates.
In many respects, households appear to be relying more heavily on debt simply to maintain existing living standards.
That is rarely a healthy long-term trend.
Housing Affordability Has Become A Structural Economic Problem
The broader issue underpinning many of these pressures is housing affordability.
For years, rising property prices have been treated as a sign of economic strength. But increasingly, they are functioning as a drag on productivity, household formation and consumer spending.
A growing proportion of younger Australians are now effectively locked out of home ownership altogether.
Others are delaying:
• Marriage
• Having children
• Household formation
• Business creation
• Long-term investment decisions
because housing costs consume such a large proportion of income.
Australia’s economy has become heavily dependent on continually rising property values, but that dependency creates fragility.
If rates remain elevated for longer, unemployment rises, or economic growth weakens materially, highly indebted households may quickly come under significantly greater pressure.
Regulators Are Clearly Concerned
The introduction of APRA’s DTI caps is perhaps one of the strongest signals that regulators themselves recognise the risks.
Australia avoided a major housing correction during the Global Financial Crisis largely because:
• Interest rates fell aggressively
• China’s commodity demand supported national income
• Population growth remained strong
• Fiscal stimulus was substantial
• Mortgage deferrals and policy support were later used during COVID
But policymakers may have less flexibility in a future downturn if inflation remains persistent.
The challenge now is that Australia simultaneously faces:
• High household debt
• Elevated property prices
• Weak productivity growth
• Slowing discretionary consumption
• Persistent affordability pressures
• Structural housing undersupply
That combination leaves the economy increasingly sensitive to shocks.
The Federal Budget Adds Further Pressure To The Housing Debate
Another major issue increasingly shaping sentiment is the growing backlash to Federal Government housing and taxation policy.
The 2025–26 Federal Budget placed substantial emphasis on housing affordability, rental supply and cost-of-living relief. However, parts of the market, particularly investors, developers and sections of the property industry, have raised concerns that some policy directions risk worsening the very supply constraints they are attempting to solve.
A central concern relates to ongoing debate around negative gearing, capital gains tax concessions and broader investor taxation settings.
While no formal abolition measures have yet been implemented, sustained political discussion around restricting property tax incentives has already contributed to uncertainty within parts of the residential investment market.
Industry groups including the Property Council of Australia, Urban Development Institute of Australia (UDIA), the Housing Industry Association (HIA) and the Australian Property Institute (API) have repeatedly warned that policy settings which discourage private investment could materially reduce future housing supply.
That concern matters because private investors still provide a substantial proportion of Australia’s rental housing stock.
Critics argue that if investor participation falls materially:
• Rental supply may tighten further
• Vacancy rates could remain structurally low
• Rents may continue rising
• Development feasibility could weaken
• Smaller builders and developers may come under greater financial stress
Several economists and market commentators have also drawn parallels to the mid-1980s period under the Hawke–Keating Government, when negative gearing was temporarily removed between 1985 and 1987. In this era aggressive changes to property taxation created significant supply-side disruptions.
During that period, parts of Australia experienced significant rental increases, particularly in Sydney and Perth, before the policy was ultimately reversed.
At the same time, advocates for reform argue that current housing policy settings disproportionately favour asset owners while locking younger Australians out of the market.
This has created an increasingly polarised debate.
On one side are those arguing Australia needs stronger intervention to improve affordability.
On the other are those warning that undermining investor participation without materially increasing housing construction may simply worsen rental shortages and affordability pressures.
The political challenge is that Australia now faces two competing realities simultaneously:
• Housing is unaffordable for many aspiring buyers
• New housing supply still relies heavily on private capital and investor participation
That tension is becoming one of the defining economic issues of the decade.
If policy settings create further uncertainty for developers, investors or lenders at a time when construction costs remain elevated and feasibility margins are already compressed, the unintended consequence could be even lower housing supply.
And in a market already suffering from structural undersupply, that may ultimately place even greater upward pressure on rents and prices over time.
Australia Has Not Reached Crisis Point — But The Direction Matters
Mortgage arrears remain comparatively low overall, unemployment remains relatively contained and many borrowers still retain savings buffers built during the pandemic years.
The RBA itself continues to emphasise that most households remain resilient overall.
However, the trend direction matters, financial stress is rising.
More households are operating with minimal financial flexibility and more borrowers are vulnerable to employment shocks.
And an increasing share of household income is being absorbed by mortgage repayments, rent, insurance, utilities and basic living costs.
Australia’s economic resilience over the past 30 years has often been underpinned by rising credit expansion and property appreciation. But debt-fuelled growth models eventually reach limits.
The critical question now is whether Australia can transition toward stronger productivity, wage growth and sustainable economic expansion, or whether the economy remains increasingly reliant on household leverage and ever-higher property prices.
Because if household debt continues rising faster than incomes, financial stress is unlikely to remain contained indefinitely.
What makes the current environment particularly sensitive is that highly leveraged systems often appear stable, until an external shock exposes underlying fragility.
History shows that major financial dislocations are frequently triggered not by the risks everyone is watching, but by the unexpected events nobody fully priced in.
In financial markets these are often referred to as “black swan” events, low-probability but high-impact shocks that rapidly alter confidence, liquidity and asset pricing.
Potential examples could include:
• A sharp rise in unemployment
• A global recession or banking event
• A major geopolitical conflict
• A sustained inflation resurgence forcing rates materially higher
• A severe downturn in China impacting Australian exports
• A domestic housing confidence shock
• Significant stress within commercial property or private credit markets
In heavily indebted economies, these types of events can create cascading effects.
Consumer spending contracts, credit availability tightens, property prices weaken, business insolvencies rise and with households operating close to financial limits, they can find themselves without meaningful buffers.
Australia has historically proven remarkably resilient through global crises, but resilience should not be confused with invulnerability.
The concern is not necessarily that Australia faces an imminent collapse, the concern is that the economic system has become increasingly dependent on continually rising debt, elevated asset values and stable confidence.
And systems built on leverage can remain remarkably stable for long periods, right up until the moment they are not.
At Wills Property, we are closely monitoring these evolving economic, financial and policy conditions on behalf of our clients. In periods of heightened uncertainty, informed decision-making, disciplined risk assessment and careful market interpretation become increasingly important, particularly in markets heavily influenced by debt, confidence and changing government policy settings.
