Here is the thing about Australia’s housing crisis that should make everyone furious: we know exactly what is causing it. We have known for years. The evidence is not contested. The solutions are well understood, extensively studied, and in many cases already working in other countries. And yet here we are, with median house prices in Sydney above $1.4 million, a generation of Australians locked out of home ownership, and a political class that treats the problem as though it were some baffling mystery beyond human comprehension.

It isn’t a mystery. It’s a choice. And understanding whose interests are served by that choice is the beginning of an honest conversation about housing in Australia.

The Four Causes Nobody Wants to Fix

1. Negative gearing and the capital gains discount. Australia allows property investors to deduct losses on investment properties against their income tax — and then halves the capital gains tax when they sell. This combination makes housing an extraordinary tax shelter for investors, artificially inflating demand and pricing owner-occupiers — particularly first home buyers — out of the market. The economic evidence that this distorts the housing market is overwhelming. Both major parties know it. Neither will touch it in any meaningful way, because approximately 2.2 million Australians own investment properties and tend to vote.

2. Zoning and planning restrictions. In most Australian capital cities, strict zoning laws prevent the kind of medium-density housing — townhouses, low-rise apartments, terraces — that would dramatically increase supply close to employment and services. Local councils, many of them dominated by homeowners whose primary financial interest is in keeping their neighbourhood’s property values high, consistently resist upzoning. State governments talk about reform and then fail to implement it against organised local opposition. Meanwhile, the only new housing gets built on the urban fringe, far from jobs and infrastructure, where land is cheap because nobody actually wants to live that far out.

3. Foreign investment rules that are poorly enforced. Foreign nationals are technically restricted from buying established residential properties in Australia. The enforcement of these restrictions has historically been inadequate, and the Foreign Investment Review Board’s resources are modest relative to the scale of the market. Whether foreign investment is a primary driver of house prices is genuinely contested in the evidence — but the perception that it is matters, and better enforcement would at minimum remove a variable from the debate.

4. Chronic undersupply of social and affordable housing. For decades, both federal and state governments have progressively withdrawn from direct investment in social housing, relying instead on the private market to provide affordable rental housing. The private market, unsurprisingly, builds where profit is highest — not where need is greatest. The result is a social housing waitlist in New South Wales alone of more than 50,000 households. The people on that list are not going to be helped by negative gearing reform or planning changes. They need direct government investment in homes, and that investment has been systematically defunded.

The Political Maths That Blocks Reform

So why doesn’t anyone fix it? Because the people who benefit most from high house prices vote in large numbers, donate to political parties, and have deeply entrenched interests in the status quo.

About two-thirds of Australian households own their home. For most of them, the family home is their single largest asset and their primary retirement strategy. Policies that would reduce house prices — even policies that would simply slow the rate of growth — are experienced by those households as an attack on their financial security. Politicians who propose serious supply-side or tax reform in housing do so at genuine electoral risk.

This is the political trap. The people who would benefit most from a functioning housing market — young Australians, renters, those trying to enter the market — are precisely the demographic least likely to vote, least likely to donate, and least likely to be organised into an effective political constituency. The people who would be most affected by reform — existing property owners — are the most engaged and powerful electoral constituency in the country.

Every politician knows this. Every politician who has been honest in private has admitted it. The Albanese government made tentative gestures toward housing supply reform. The Greens blocked them in the Senate while simultaneously claiming to care about housing affordability — an act of political cynicism so breathtaking it deserves its own article. The Liberals oppose anything that might reduce property values. The result is that nothing changes.

What Would Actually Work

The evidence points clearly to a package of reforms that, applied together, would genuinely improve housing affordability over time. None of them are radical. All of them are politically difficult:

• Gradually reform negative gearing — not abolish it overnight, but limit it to new construction so that tax incentives encourage building rather than speculating on existing stock.
• Reduce the capital gains discount — the 50% CGT discount for assets held over 12 months is extraordinarily generous and overwhelmingly benefits the wealthy. Reducing it to 25% would raise significant revenue and reduce the relative attractiveness of property as a tax shelter.
• Serious upzoning — particularly within 10km of major city centres and transport hubs. Every city that has successfully improved affordability has done so by increasing density close to where people want to live.
• Federal government direct investment in social housing — not through complicated funding arrangements with state governments, but through direct commissioning of new social housing stock on a scale commensurate with the problem.
• Renters’ rights reform — until housing is more affordable, the millions of Australians who rent need substantially stronger protections than they currently have, including limits on rent increases and security of tenure.

None of these is a silver bullet. All of them together would make a material difference over a decade. The reason they haven’t been implemented is not that they don’t work — it’s that the political cost of implementing them is borne immediately, by organised and angry property-owning voters, while the benefits accrue slowly, to people who aren’t yet politically powerful enough to demand them.

That is the honest answer to why Australia’s housing crisis continues. It’s not complicated. We just don’t want to fix it.
