For decades, buying a home in your twenties was simply what Australians did. But census data spanning thirty years tells a different story — each generation is less likely to own a home than the one before it. Baby Boomers achieved 66% home ownership by age 39. For Millennials, that figure has collapsed to 55% — and the decline shows no sign of stopping.
The core of the crisis is simple: house prices have grown far faster than the wages needed to pay for them. Since 2003, Australian house prices have more than tripled in index terms — rising to 333 — while wages have barely nudged past 183. The widening gap between the two lines is not just a chart. It is the distance between a generation that could afford to buy, and one that cannot.
Housing stress is not evenly distributed — it falls hardest on those who can least afford it. Across every capital city, low-income earners spend more than the 30% mortgage stress threshold just to keep a roof over their heads. In Sydney, a low-income earner spends 72% of their gross income on mortgage repayments — nearly two and a half times the stress threshold. Even in Perth, the most affordable major city, low earners are still above the line.
It is not just mortgage repayments that have become unmanageable — getting into the market in the first place has become a decade-long challenge. In 2015, saving a 20% deposit on a Sydney home took around 8 years. By 2024, that figure had jumped to 14 years. Brisbane has seen the sharpest surge, with prices rising 160% since 2015 — turning a once-affordable city into a near-impossible market for first-time buyers.
The generational decline in home ownership is not inevitable — but reversing it will require deliberate policy action. Under the current trajectory, Gen Z home ownership could fall below 48% by 2040. Moderate reforms — such as shared equity schemes and stamp duty relief — could slow the decline. Only significant structural reform, including housing supply expansion and tax reform, offers a path back toward recovery. The choice between these futures is a political one. The data makes the stakes clear.
