Australians believe 31 is the age at which living at home with your parents becomes socially unacceptable — but a widening rental crisis is making that judgement increasingly difficult to square with financial reality, a new national survey has found.
The survey, conducted by financial comparison platform Finder among 1,010 Australians, asked respondents to nominate the age they considered "too old" to still be residing in the family home. The average answer landed at 31 years old — a figure that sits in stark contrast to data showing record numbers of young Australians are staying put precisely because they can't afford not to.
Who draws the line where — and the generational divide
The survey revealed notable differences in attitude depending on the respondent's own generation. Gen Z and Baby Boomers held the strictest views, both nominating 30 years old as the cut-off point. Millennials and Gen X were marginally more lenient, putting the threshold at 32.
Parents of children under 18 were also less forgiving than those without kids, nominating 30 compared to 32 among non-parents.
Finder's personal finance expert Sarah Megginson said the social expectations captured in the survey are increasingly disconnected from the financial pressures facing renters and aspiring homeowners.
"We know renters are doing it tough — Finder's data shows 47 per cent of Aussie tenants struggled to pay their rent in June," Megginson said. "In many suburbs, renters are spending half of their weekly income or more just on rent, and after other bills are paid there's not much left over for groceries and simply living."
The standard benchmark for rental stress is defined as spending 30 per cent of household income on rent — a threshold Megginson described as something many Australians would now "welcome as relief" given how far costs have climbed beyond it.
A rental market that keeps getting harder
The survey findings land against a backdrop of relentlessly rising rents. National figures show rents increased 3.08 per cent quarter-on-quarter in June and 6.35 per cent over the year, pushing the median weekly rent for a dwelling to $670 nationally.
The steepest annual increases were recorded in:
- Perth — up 10.29 per cent to a $750 weekly median
- Hobart — up 9.09 per cent to $600
- Darwin — up 7.69 per cent to $700
- Brisbane — up 6.92 per cent to $695
- Sydney — up 6.67 per cent to $800, the most expensive capital
- The ACT — up 4.84 per cent to $650
Megginson said the knock-on effects extend beyond the rental market itself, reshaping when and how Australians reach traditional life milestones. "The traditional milestones of adulthood are being pushed further back, with many people delaying moving out, buying a home and starting a family," she said.
Young Australians are staying home longer — and the trend is accelerating
Research from demography and social research firm McCrindle underscores just how much has shifted in a generation. In 2006, around 60 per cent of 19-year-olds were living at home with their parents. By 2021, that figure had risen to 70 per cent.
The firm attributed the trend to a combination of high student debt and an intensely competitive housing market, with some young people returning to the family home after initially moving out — specifically to accelerate savings toward a deposit.
The shift has also prompted a broader rethink of multi-generational living arrangements. The McCrindle research found that almost three in five Australians (57 per cent) said they were open to or would welcome living in a home with three or more generations under the same roof. Currently, 12 per cent of Australians live in such an arrangement, while 32 per cent have done so at some point in the past.
Australians who speak a language other than English at home were significantly more likely to live in multi-generational households, reflecting cultural traditions where such arrangements are the norm rather than the exception.
Those who have experienced multi-generational living firsthand have noted that it can ease financial pressure and help families share caring responsibilities — particularly as relatives age. However, some have pointed out that the typical Australian home is not well designed to accommodate several generations comfortably.
Social stigma versus financial survival
The tension at the heart of the Finder survey is one many Australian families are navigating in real time: a set of social expectations formed in a different economic era, now colliding with a housing market that has fundamentally changed the rules.
With rents consuming an ever-larger share of take-home pay and property prices keeping homeownership out of reach for many, the question of when it's "too old" to live at home may be less about personal milestones and more about economic circumstance.
If the housing market continues on its current trajectory, the average age Australians consider acceptable for living at home may need to shift too — whether social attitudes are ready for that or not.
