Everyone blames Boomers for the housing crunch – but here’s the real reason they won’t downsize

For years the finger has been pointed squarely at older Australians: sitting pretty in big family homes while young couples get locked out of the market. It is the flip side of the “avocado toast” jab young buyers cop over their spending habits, except this time the accusation is that an entire generation is hoarding space it no longer needs. But ask the people who actually study the housing market, and the picture looks rather different.

Supply, not stubbornness, is widely regarded as the real engine of Australia’s affordability crunch. That is precisely why downsizing keeps coming up whenever the conversation turns to fixing the system, because unlocking homes already standing beats waiting years for new estates to be built on the city fringe.

CBA Chief Economist Luke Yeaman put it plainly when he said getting the settings right matters more than where the blame lands. “Getting downsizing right targets one of the fundamental issues of housing affordability by unlocking established housing stock without having to wait years for new outer-suburban developments,” Yeaman said.

That word “right” carries weight. It suggests the barrier is not sentiment or selfishness but the mechanics of downsizing itself – whether moving to a smaller place genuinely makes financial sense once all the costs and incentives are weighed up. For many older Australians eyeing a move, the maths simply has not stacked up the way policymakers would like.

It is a far more useful question than the one usually asked. Rather than “why won’t Boomers move”, the sharper version is “what would make moving worthwhile” – a distinction that shifts responsibility from individual choice to policy design.

Older Australians weighing up a move are not clinging to empty rooms out of spite. Most are simply doing what anyone would: working out whether a smaller home actually leaves them better off, or just lighter in the pocket and further from everything familiar.

Supply fixes that make downsizing genuinely worthwhile would free up established housing stock without anyone having to feel like the villain of someone else’s affordability story. As Yeaman’s comments suggest, the answer was never about blame. It was always about getting the incentives right.
