Here’s a hard truth: Australia’s skyrocketing house prices aren’t just a local problem—they’re part of a global trend, and population growth is at the heart of it. But here’s where it gets controversial: while some experts, like Greg Jericho from The Australia Institute, argue that the Howard Government’s 1999 decision to slash the capital gains tax (CGT) rate fueled the housing crisis, the International Monetary Fund (IMF) paints a different picture. According to the IMF, Australia’s housing affordability nightmare isn’t just about tax policies—it’s deeply tied to its inability to build homes fast enough to keep up with its booming population, largely driven by immigration. And this is the part most people miss: countries like the UK, Canada, New Zealand, and Sweden are facing similar housing challenges, suggesting that global population pressures are a bigger culprit than local tax tweaks.
The IMF’s 2025 report highlights that Australia’s population growth has been among the fastest in the OECD, outpacing housing supply. When combined with shrinking household sizes, this has created a perfect storm of surging housing demand. While Australia’s dwelling investment as a share of GDP has slightly exceeded the OECD average since 2000, its population growth—second only to Israel—has left the country in a chronic housing shortage. Independent economist Gerard Minack echoes this, arguing that population growth is likely the single most important factor driving up both house prices and rents.
But let’s pause for a moment: Is it fair to blame immigration for the housing crisis, or are we missing other critical factors? The IMF acknowledges that subsidies, household formation, and aggregate demand also play roles, but the data is clear: Australia’s housing supply simply hasn’t kept pace with its population boom. Worse, the National Housing Supply and Affordability Council and KPMG predict that this gap will persist, with demand outstripping supply for years to come. This raises a provocative question: If population growth is the primary driver, should Australia reconsider its immigration policies to ease housing pressures, or is there a more balanced solution?
Here’s the bottom line: While tax policies like the CGT discount deserve scrutiny, the evidence suggests that Australia’s housing crisis is fundamentally a supply-and-demand issue, exacerbated by rapid population growth. The real debate isn’t just about taxes—it’s about how to build enough homes for a growing population. What do you think? Is immigration the real problem, or are we overlooking other solutions?
