55 Years of Data: Australian Property Has Never Had a Decade of Negative Growth

People call property investment risky. The data says otherwise. Across every decade since 1970, Australian property values have gone up — every single time.

People call property investment risky. We understand why — it’s a large sum of money, the market moves in ways that feel unpredictable, and there’s always a headline warning of a crash just around the corner.

But here’s what 55 years of data actually shows: Australian property has never recorded a decade of negative growth. Not once.

What the Numbers Say

Sydney house prices in 1970 averaged around $18,700. In today’s dollars, adjusted for inflation, that’s approximately $155,000.

By 1980 the average was $76,500 — about $330,000 in today’s money. By 1990, $194,000. By 2000, $287,000. The pattern holds across every decade, through recessions, interest rate spikes, global financial crises, and pandemics.

No decade of negative growth. Not the 1970s inflation crisis. Not the early 1990s recession. Not the GFC. Not COVID.

Short-Term Noise vs Long-Term Signal

This doesn’t mean property never falls. It does. Individual years, individual markets, individual assets can and do go backwards. The GFC saw values drop in some suburbs. Rate rises in 2022 and 2023 caused corrections in certain segments.

But the distinction matters enormously: short-term volatility is not the same as long-term risk.

If your investment horizon is 5 years, you’re exposed to that volatility. If your horizon is 10 or more years — which it should be for a serious property strategy — the historical record is remarkably consistent.

The investors who lost money in property almost always fall into one of three categories: they bought the wrong asset, they bought in the wrong location, or they needed to sell at the wrong time. None of those failures are inherent to property as an asset class. They’re failures of strategy and selection.

What This Means in Practice

When a Stonehhart client asks us “is now a good time to buy?”, our honest answer is: the data suggests there’s never been a bad decade to buy well-selected Australian property.

That’s not a sales pitch. It’s a fact that’s held for more than half a century.

The more important question isn’t when to buy. It’s what to buy, where, and why — and whether your strategy is built to hold through the inevitable short-term noise on the way to long-term growth.
