The Sydney property bubble has burst, but not in the way policymakers hoped. Prices remain stubbornly high while wages stagnate, and the dream of home ownership is slipping further from reach for a generation. Down Under, the housing crisis is a fiscal black hole, draining household budgets and distorting the economy. Yet across the globe, Britain’s own housing market reforms, though imperfect, offer a roadmap for Australia’s affordability woes. As a financial editor who has watched the City of London navigate similar turbulence, I see clear parallels—and cautionary tales.

At the heart of Australia’s malaise is a supply-demand imbalance amplified by easy money. The Reserve Bank of Australia’s low-rate era, now ending, fuelled a property frenzy. Investors piled in, leveraging cheap credit, while first-home buyers were left in the dust. The result: a housing stock that is both expensive and scarce. This is a classic case of market distortion. Gilt yields rise, inflation persists, and the cost of capital climbs—yet house prices defy gravity. Something must give.

The UK faced a similar predicament after the 2008 financial crisis. But rather than rely solely on central bank policy, Westminster intervened with supply-side reforms. The Help to Buy scheme, while criticised for inflating prices, got builders into a frenzy of construction. Coupled with changes to planning laws that accelerated development, the UK added nearly 2 million homes in the decade after 2010. This did not solve the crisis, but it cooled the market compared to Sydney’s runaway growth.

Australia could learn from this. First, embrace density. The UK’s suburban sprawl has been curtailed by infill projects and brownfield conversions. Australia’s cities resist such change, clinging to the quarter-acre block myth. But land is finite; supply must come from vertical living. The NIMBYism that blocks apartment towers in Melbourne or Brisbane is a luxury the economy cannot afford. Fiscal discipline demands that we price in the cost of exclusionary zoning.

Second, tax reform is overdue. Britain’s stamp duty, while hated, is less punitive than Australia’s state-based imposts. More critically, the UK has slowly moved to tax property holdings, not just transactions. The annual tax on enveloped dwellings, aimed at foreign investors, has reduced the stock of luxury empty houses. Australia’s lack of a land tax on principal homes and generous capital gains discounts for property investors are glaring loopholes. They fuel speculation and inflate prices. Closing these would cool the market and raise revenue without stifling the economy.

Third, central bank policy must align with housing goals. The Bank of England’s tightening cycle has raised mortgage costs, but it has also forced a reassessment of risk. The RBA’s reluctance to hike earlier has allowed the property bubble to persist. Now, with inflation stubbornly above target, the RBA is playing catch-up. The capital flight from Australian bonds and the falling AUD are symptoms of credibility lost. A clear-eyed focus on price stability would help housing by removing the tailwind of negative real rates.

However, the UK’s path is not without pitfalls. Brexit unleashed labour shortages that stalled construction. The Help to Buy scheme, while boosting demand, has been accused of enriching builders rather than helping buyers. And the rise in homelessness persists, a reminder that affordability is not just about prices, but about access. Australia must guard against these outcomes. Any reform should target the root cause: chronic undersupply. That means bulldozing red tape for development and empowering local authorities to build social housing when the market fails.

Let us be clear: housing is not a pure market good. It is shelter, a necessity. But our system relies on market forces to allocate it. When those forces fail, as they have in Australia, government intervention is not only justified but necessary. The question is what kind. The UK’s experience suggests that subsidies alone are a dead end. The real lesson is to fix the supply chain: land, labour, and materials. Australia has the space and the resources; it needs the will.

Investors watch closely. If Australia fails to tackle this crisis, the economic consequences will ripple beyond housing. Consumer spending, already weak, will suffer as households divert more to rent. The construction sector, starved of projects, will shed jobs. And the fiscal position, already strained by welfare payments and tax breaks, will worsen. The bottom line is clear: Australia must reform its housing market, or risk a deeper crisis that no central bank can fix.
