Plenty of older Australians want to leave the family home. They just can’t face the bill and the bother. That is the central finding of the 2026 Downsizing Australia study, which surveyed more than 2100 buyers on a major property portal, including people over 50 who plan to downsize.
The headline numbers are telling. The hassle of moving was the top worry at 29%. Stamp duty followed close behind at 26%. Interest in moving is there. The friction is what stops it.
What the survey says, and what it doesn’t
This is a self-selected sample of portal users, so treat it as a read on motivated would-be movers rather than a census of every over-55 homeowner. Still, the pattern fits the wider data on how people respond to transaction costs.
When buyers do picture the next home, the priorities are practical:
- Low maintenance: 79%
- Security: 62%
- Nearby amenities: 61%
And two-thirds (66%) of those with adult children say those children sway the decision. Downsizing is rarely a solo call.
Key numbers
- 29% of surveyed would-be downsizers rank the hassle of moving as their top worry
- 26% name stamp duty
- Roughly 7% fewer housing transactions for each one-percentage-point rise in the stamp duty rate, per PropTrack and e61 Institute research cited in the study
- Today, 29% of Australians are aged 55 or over, and that share is forecast to climb to 35% by 2050.
Why a transaction tax locks up homes
Stamp duty is charged on the price of the home you buy, and it is paid in cash at settlement. For a downsizer, that is a real cost with no matching benefit. They are often moving to something smaller, sometimes in a more expensive location, and the tax lands anyway.
The PropTrack and e61 Institute estimate is the part worth pausing on. Turnover falls by about 7% for each additional percentage point on the duty rate. Fewer sales means fewer homes changing hands, and that leaves many large houses underused while younger, larger households compete for what is on the market.
We covered the other side of this in our look at why spare bedrooms stay empty across the over-55 cohort. The stock exists. The incentive to release it is weak.
Releasing existing homes versus building new ones
Here is the supply angle. New construction is slow and expensive, and the pipeline is running behind. Our piece on the housing accord shortfall shows how far targets have slipped.
If even a modest share of older owners moved because the tax barrier fell, the effect would be near-immediate: a family-sized home listed, a smaller home bought, and a chain of other moves behind it. A building approval takes years to become a keyed-up dwelling. A reduced duty bill could change a decision this quarter.
The catch is that this is a probability, not a promise. Cutting duty does not fix the hassle, which ranked first in the survey. And governments that rely on stamp duty revenue would need to replace it, which is why reform tends to stall.
The non-tax factors that still matter
An industry economist quoted in the coverage stressed that downsizing is a process that evolves over time, not a single decision. People move in stages, and life events drive timing more than tax settings do.
One operator in the retirement-community sector pointed to land lease arrangements, which carry no stamp duty. That is a useful data point: where the tax disappears, an option opens. But it is a niche product, and it suits some buyers and not others, with different ownership and exit terms to understand before signing.
What this means if you’re weighing a move
If you are over 55 and thinking about downsizing, price the full cost of the move, not just the purchase price. Add stamp duty, selling costs and the cash tied up in transition, then compare it with what you would save in running costs and maintenance over the next decade. If the numbers are close, ask whether a non-duty route such as a land lease suits your situation.
