The median house price in Sydney is now over $1.4 million. The median full-time income in Australia is roughly $65,000. That's a ratio of 22 to 1. Twenty-two years of gross income - before tax, before rent, before food - just to pay for a house.
I'm in my late twenties. I work in decentralised finance. I earn well above the median. And even on my salary, the arithmetic of buying a home in the city I grew up in simply does not work.
I didn't leave Australia just because of the tax system - though that was a large part of it. The housing crisis was equally decisive. It forced me to confront an uncomfortable reality: the system I was raised to trust - work hard, pay your taxes, buy a home - was not designed for my generation. It was designed to protect the wealth of the generations before us.
This article is my attempt to explain - with data, not just frustration - how every major policy lever in Australia has been configured to increase housing demand while constraining supply. It is not a neutral explainer. It is the perspective of someone who looked at the incentives, understood who benefits, and decided the game was rigged.
How Did Australian Housing Become the Most Expensive in the World?
Australia's housing market is among the most unaffordable on the planet, with a national price-to-income ratio above 13x and Sydney exceeding 22x. According to the Demographia International Housing Affordability report, Sydney consistently ranks alongside Hong Kong as the least affordable major city globally - the result of three decades of policy choices that amplify demand while systematically constraining supply.
It wasn't always this way. In 1990, the median house price in Sydney was roughly 6x the median household income - expensive by global standards but broadly accessible to dual-income families. Over the following thirty years, that ratio nearly quadrupled.
The OECD's housing affordability index places Australia near the bottom of developed nations. The Reserve Bank of Australia's own research papers have acknowledged that housing has outpaced income growth for decades, driven by a combination of tax incentives, credit expansion, population growth, and supply-side constraints.
What's remarkable is not that any single policy caused this. It's that every major policy lever - tax treatment, immigration settings, planning regulations, demand subsidies, banking incentives - pushes in the same direction. Upward.
That's not an accident. That's a system working as designed.
How Does Negative Gearing Inflate Property Prices?
Negative gearing allows Australian property investors to deduct rental losses against their salary income, effectively subsidising property speculation with taxpayer money. ATO statistics show that over 1.3 million Australians claim negative gearing deductions annually, and the policy costs the federal budget billions in foregone revenue each year - revenue that is transferred, in effect, from renters and first-home buyers to existing property owners.
Here's how it works in practice. An investor on a $150,000 salary buys an investment property. The rental income doesn't cover the mortgage interest and expenses, generating a $20,000 loss. Under negative gearing, that $20,000 loss is deducted from their salary, reducing their taxable income to $130,000. At the 37% marginal rate plus Medicare Levy, that's a tax saving of roughly $7,800.
This means the government is effectively paying the investor $7,800 per year to hold a loss-making property. The investor doesn't mind the loss because they're banking on capital growth - and with prices rising 7–10% annually for decades, the strategy has been enormously profitable.
But consider the first-home buyer competing at the same auction. They don't get a tax deduction for their mortgage. They can't offset housing costs against their income. They're bidding against someone who is structurally subsidised to pay more.
ATO data reveals the scale: in any given year, the majority of property investors report a net rental loss. According to Treasury analysis, the combined cost of negative gearing and the CGT discount was estimated at over $12 billion annually in foregone revenue. That is a staggering subsidy flowing predominantly to higher-income households - ATO data consistently shows that the benefits of negative gearing are concentrated among taxpayers in the top income brackets.
Both major parties know this. In 2019, the Australian Labor Party went to the federal election with a policy to limit negative gearing to newly built properties only - a modest, evidence-based reform. They lost. The Coalition ran a fear campaign warning that house prices would fall, and voters - the majority of whom own property - chose to protect their wealth. Negative gearing is now politically untouchable, despite near-universal acknowledgement among economists that it inflates prices and worsens inequality.
How Does the Capital Gains Tax Discount Encourage Property Speculation?
The 50% capital gains tax discount, introduced by the Howard Government in 1999, allows investors who hold assets for more than 12 months to pay tax on only half of their capital gain. For property investors, this halves the effective tax rate on housing gains - supercharging property as a speculative asset class and incentivising investors to treat housing as a wealth-generation vehicle rather than shelter.
Before the 1999 change, capital gains were indexed to inflation. You only paid tax on the real gain - the portion above the rate of inflation. This was economically rational: it ensured that investors weren't taxed on phantom gains created by rising prices. The Howard Government replaced inflation indexation with a flat 50% discount, ostensibly to simplify the system.
The consequences were transformative. Consider an investor who buys a property for $500,000 and sells it five years later for $800,000. The $300,000 gain is halved to $150,000 for tax purposes. On a top marginal rate of 45%, the tax bill is $67,500 - an effective rate of 22.5% on the actual gain. Under the old indexation method, with cumulative inflation of roughly 15% over five years, the indexed cost base would be $575,000, the taxable gain $225,000, and the tax bill $101,250 - significantly higher.
Combined with negative gearing, this creates a powerful dual incentive. An investor can claim losses against their salary income during the holding period (reducing their tax bill each year), then pay tax on only half the gain when they sell. The system effectively pays investors to speculate on housing.
RBA research has repeatedly noted that the interaction between negative gearing and the CGT discount has contributed to increased investor activity in the housing market. The proportion of housing loans going to investors rose sharply after 1999 and has remained elevated since. This is not a mystery - the policy settings made property the single most tax-advantaged asset class in Australia.
How Does the First Home Owner Grant Actually Increase Prices?
The First Home Owner Grant (FHOG), introduced alongside the GST in 2000, provides first-time buyers with a cash grant - typically $10,000 to $25,000 depending on the state and property type. However, economic research consistently demonstrates that demand-side subsidies with no supply component are capitalised into prices, meaning the benefit is captured by sellers and developers rather than by the buyers the policy is intended to help.
The logic is straightforward. If every first-home buyer in a market suddenly has an extra $15,000 to spend, and the number of available homes hasn't changed, then prices rise by approximately $15,000. The subsidy doesn't improve affordability - it inflates the baseline.
Academic research from the University of Melbourne and the Australian Housing and Urban Research Institute (AHURI) has found evidence of exactly this effect. Studies examining the introduction and expansion of the FHOG showed that price increases in the eligible property segments correlated closely with the grant amounts. The boost versions of the grant introduced during the Global Financial Crisis - up to $21,000 in some states - were associated with proportional price increases in the sub-$750,000 market segment.
Developers are the primary beneficiaries. Many new-build estates in outer-suburban areas are priced precisely to absorb the FHOG amount, with marketing materials explicitly referencing the grant as a deposit contribution. The policy has become a transfer from taxpayers to property developers, laundered through the bank accounts of first-home buyers.
The recurring pattern is unmistakable: demand subsidies without supply reform simply push prices higher. Every dollar spent on the FHOG would have been more effective if directed toward increasing the housing stock - but increasing supply would lower prices, and lowering prices is not something any level of Australian government is willing to do.
How Does High Immigration Affect Housing Supply?
Australia runs one of the highest per-capita immigration programmes in the OECD, with net overseas migration adding between 200,000 and 400,000 people annually in recent years. This is not an argument against immigration - the economic, cultural, and demographic benefits are well established. The problem is that successive governments have pursued high immigration for headline GDP growth without building anywhere near enough housing to accommodate the resulting population increase.
ABS data tells the story clearly. In the five years to 2024, Australia's population grew by approximately 1.5 million people - driven primarily by net overseas migration, which surged post-pandemic to record levels exceeding 500,000 in a single year. Over the same period, housing completions averaged roughly 170,000–180,000 dwellings per year. The National Housing Finance and Investment Corporation (NHFIC) estimated that Australia needed approximately 200,000 new dwellings per year to keep pace with demand - a target it has consistently failed to meet.
The federal government's own National Housing Accord, announced in 2022, set a target of 1.2 million new homes over five years starting from 2024. By early 2026, progress against that target was already well behind schedule, with construction industry capacity constraints and rising costs making the target increasingly unrealistic.
The political economy is revealing. Immigration adds to GDP - more people means more economic activity, even if GDP per capita is flat or declining. This gives the government a growth headline without requiring the politically difficult work of building infrastructure and housing. The cost - higher rents, longer commutes, lower affordability - is externalised onto the population, particularly onto renters and young people who don't yet own property.
I want to be clear about this: I am not anti-immigration. I am an immigrant myself, living in Malaysia. The problem is not that people want to come to Australia. The problem is that the government invites them without building homes for them to live in - and existing homeowners benefit from the resulting scarcity.
How Does Foreign Investment Drive Up Property Prices?
Foreign investment in Australian residential property - particularly from China prior to the tightening of FIRB (Foreign Investment Review Board) rules in 2015–2017 - added significant demand-side pressure to capital city markets. However, the deeper issue is not foreign buyers alone but the domestic banking system that profited from the lending boom, internalising gains while externalising the cost of unaffordable housing onto the public.
During the peak years of foreign investment (2012–2016), FIRB approval data showed billions of dollars flowing into Australian residential property, concentrated in Sydney and Melbourne. The rules required foreign buyers to purchase new builds only, but enforcement was widely criticised as inadequate. Treasury reviews found systemic non-compliance, with existing properties being purchased in breach of the rules and minimal penalties applied.
But focusing solely on foreign buyers misses the broader picture. The Australian banking system - dominated by the four major banks - made record profits throughout the housing boom. Residential mortgages account for the majority of Australian bank lending. When property prices rise, banks' loan books grow, their collateral appreciates, and their profits increase. There is no structural incentive for banks to cool the market - quite the opposite.
The Banking Royal Commission (2017–2019) exposed widespread irresponsible lending practices, including loans issued without adequate verification of income or expenses. While subsequent reforms tightened lending standards, the fundamental incentive structure remains: banks profit from more and larger mortgages, which means banks profit from higher property prices.
When the institutions that control credit - and the regulators tasked with overseeing them - all benefit from rising prices, the idea that the market will self-correct is naive. The system extracts wealth from borrowers and transfers it to lenders and existing asset holders. That is its function.
Why Isn't Australia Building Enough Homes?
Australia's chronic housing undersupply is the product of restrictive council zoning, slow planning approvals, rising construction costs, and state government dependence on stamp duty revenue. Together, these forces protect existing homeowners' property values at the direct expense of new supply - making NIMBYism not just a social attitude but an entrenched policy position at every level of government.
Start with zoning. The vast majority of residential land in Sydney and Melbourne is zoned exclusively for detached housing. Proposals to allow medium-density development - townhouses, low-rise apartments - are routinely blocked by local councils responding to existing residents who oppose any change that might affect their property values, views, or neighbourhood character. The economic term for this is "regulatory capture" - the planning system is controlled by the people it was meant to regulate.
Planning approval timescales compound the problem. A significant development in Sydney can take 3–5 years from application to approval, with multiple rounds of community consultation, environmental assessment, and legal challenge. Each delay adds cost and risk, discouraging development and reducing the total number of homes built.
Construction costs have risen dramatically. The ABS Producer Price Index for house construction rose over 30% between 2020 and 2024, driven by materials costs, labour shortages, and supply chain disruptions. Builder insolvencies reached record levels, further reducing construction capacity.
Then there's stamp duty - the tax that state governments charge on property transactions. In NSW, stamp duty on a $1.4 million property exceeds $60,000. This revenue is a major source of state government funding. A state government that allows prices to fall is a state government that cuts its own revenue. The incentive is to maintain - or increase - prices, not to improve affordability.
Every level of government benefits from the status quo. Local councils protect existing residents. State governments protect their stamp duty revenue. The federal government protects the wealth effect that keeps consumer spending buoyant. There is no institutional actor with both the power and the incentive to increase supply and lower prices.
What Would Actually Fix Australian Housing?
Genuine reform would require removing negative gearing for future purchases, replacing the CGT discount with inflation indexation, abolishing stamp duty in favour of a broad-based land tax, overhauling zoning to permit density, and linking immigration intake to housing completion targets. None of this is technically difficult. All of it is politically impossible - because the majority of Australian voters are homeowners who benefit from high prices.
Let me outline what an evidence-based reform programme would look like:
Abolish negative gearing for existing properties. Limit the deduction of rental losses to rental income only - as is standard in most OECD countries. Allow negative gearing only for newly constructed dwellings to redirect investment toward increasing supply rather than bidding up existing stock.
Replace the CGT discount with inflation indexation. Return to the pre-1999 system where gains are adjusted for inflation. This removes the speculative incentive while ensuring investors aren't taxed on phantom gains. It's fairer and more economically rational.
Replace stamp duty with a broad-based land tax. Stamp duty discourages transactions and locks people into unsuitable housing. A land tax - applied annually based on land value - would encourage efficient use of land, incentivise downsizing, and provide governments with a stable revenue source that doesn't depend on high prices. The ACT has been transitioning to this model since 2012, providing a working template.
Reform zoning to allow density. Override local council vetoes on medium-density development near transport corridors. New Zealand's Medium Density Residential Standards (MDRS), passed in 2021, provide a precedent - allowing three dwellings of up to three storeys on most residential sites in major cities without resource consent.
Tie immigration intake to housing completions. Set net migration targets based on demonstrated housing supply capacity. If completions fall below target, reduce intake until supply catches up. This preserves the economic benefits of immigration while preventing the demand-supply mismatch that drives prices.
The reason none of this will happen is not economic complexity - it's political arithmetic. Over 66% of Australian households own their home. Any policy that meaningfully reduces prices will be opposed by the majority. Politicians who propose it lose elections. Politicians who protect the status quo win them.
This is the fundamental problem: the system is working exactly as designed. It's just not designed for everyone.
Why I Chose to Leave Instead of Wait
After analysing every lever of Australia's housing system - the tax incentives that subsidise investors, the demand subsidies that inflate prices, the supply constraints that prevent correction, and the political dynamics that make reform impossible - I concluded that waiting for the system to change was not a rational strategy. Instead, I did the maths on leaving, and the opportunity cost of staying in Australia was extraordinary.
I sat down and ran the numbers. Buying a median-priced home in Sydney meant a mortgage north of $1.1 million (assuming a 20% deposit I didn't have). At current interest rates, that's roughly $500,000 in interest payments over 30 years - paid from post-tax income. On a property already priced at 22x the median income. In a market propped up by policies designed to prevent any correction.
Or I could move to Malaysia. Pay zero income tax on foreign-sourced income. Rent a premium apartment in Kuala Lumpur for $800 per month. Invest the difference - the roughly $200,000 per year I was losing to tax and inflated living costs - into assets that would compound over time rather than servicing a mortgage on an overpriced asset.
The decision, when stripped of emotion, was not difficult. It was obvious.
I'm aware this isn't available to everyone. I work remotely in an industry that pays well and doesn't require physical presence. Not everyone has these conditions. But for those who do - and there are more of us than governments would like to admit - the question isn't can you leave. It's why haven't you already.
The housing crisis was a catalyst, but it revealed something deeper. Australia's economic model relies on extracting wealth from the young and mobile to protect the assets of the old and established. High taxes fund services that disproportionately benefit homeowners. Immigration drives growth that inflates property portfolios. Zoning protections preserve neighbourhood character at the expense of the next generation.
I don't resent the country I grew up in. But I refuse to participate in a system that asks me to work for decades to afford something that previous generations bought on a single income. The world is bigger than one country, and the opportunities elsewhere - for tax efficiency, for affordability, for quality of life - are extraordinary.
If you're reading this and the numbers resonate, I'd encourage you to understand what it takes to break Australian tax residency and run the comparison yourself. It took me months to research and plan. It took one spreadsheet to decide.
Frequently Asked Questions
Is Australian housing in a bubble?
Whether it qualifies as a traditional bubble is debated, but the fundamentals suggest structural overvaluation. With a median price-to-income ratio above 13x nationally and over 22x in Sydney, prices are sustained by policy incentives (negative gearing, CGT discount), constrained supply, and high immigration rather than by underlying income growth. A sudden policy change or credit contraction could trigger a correction, but the political incentive is to prevent this at all costs - the RBA, APRA, and federal government would almost certainly intervene with rate cuts and stimulus before allowing a significant decline.
Will negative gearing ever be abolished?
It is unlikely in the near term. Labor took a policy to limit negative gearing to new builds to the 2019 federal election and lost, largely because the Coalition framed it as an attack on property values. With over two-thirds of Australian households owning property, any party proposing to reduce prices risks alienating the majority of voters. The Greens and some independent MPs advocate for reform, but neither has sufficient parliamentary power to legislate change. Negative gearing has become politically untouchable.
How does Australia compare to other countries on housing affordability?
Poorly. According to OECD data and the Demographia International Housing Affordability report, Australia consistently ranks among the least affordable housing markets in the developed world. Sydney's median multiple exceeds 13, alongside Hong Kong as the most expensive major city globally. By contrast, cities like Houston, Chicago, and most of Japan maintain median multiples below 5. Even London and New York - traditionally expensive - have lower price-to-income ratios than Sydney and Melbourne.
Can young Australians still afford to buy a home?
For most, not without significant family assistance. ABS data shows the home ownership rate among Australians aged 25–34 has fallen from over 50% in the early 2000s to below 40%. The typical deposit for a Sydney home now exceeds $280,000, which would take over a decade to save on the median income even with aggressive budgeting. The growing reliance on the "Bank of Mum and Dad" means housing wealth is increasingly inherited rather than earned - entrenching intergenerational inequality.
What would happen if Australian house prices fell 30%?
A 30% correction would wipe roughly $3 trillion from household wealth, push many recent buyers into negative equity, and likely trigger a credit contraction as banks tightened lending standards. This is precisely why the RBA, APRA, and federal government would intervene aggressively - with rate cuts, fiscal stimulus, and lending support - before allowing such a fall to occur. The system is designed to prevent correction, which means the underlying imbalances continue to grow until they become unsustainable.
Does immigration cause high house prices in Australia?
Immigration is a contributing factor but not the root cause. Australia's net overseas migration programme adds 200,000–400,000 people annually, creating significant housing demand. The problem is not immigration itself - which delivers substantial economic and demographic benefits - but the failure to build enough housing to match population growth. When governments pursue high immigration for GDP growth without matching it with supply, prices rise. The solution is not less immigration but more housing.
