Australian Households Spend Record 33.1% of Income on Rent Amid Housing Crisis
Australian households are now dedicating a record 33.1 per cent of their income to rent, highlighting a deepening affordability crisis in the nation's housing market. This alarming statistic comes as Perth rents have rebounded sharply, jumping to new records and intensifying pressure across the country.
National Vacancy Rates Hit Record Low
According to new data from Domain, the national vacancy rate for rental housing fell to a historic low of 0.7 per cent in the March quarter. While some tightening was anticipated during the traditionally busy start-of-year period, Domain noted that the scale of the decline underscores just how constrained housing supply remains. Nicola Powell, Domain's chief residential economist, explained that the results indicate renters can no longer absorb higher rents, even during a quarter that typically delivers strong rental growth.
"Three months ago, we warned that renters were running out of capacity to absorb higher rents," Dr Powell said. "Even during the usually stronger March quarter, this month's data shows that affordability ceiling has now been reached. Vacancy rates are lower than ever and supply remains incredibly tight, but rent growth is no longer accelerating everywhere. That tells us households simply can't stretch any further."
Perth Leads with Sharp Rent Increases
Perth emerged as the standout performer across the country, experiencing the nation's largest quarterly lift in median rents. Rents jumped 5.7 per cent or $40 over the March quarter to a record $740 per week, following two quarters of stability. This quarterly increase was the strongest since December 2022. The city's vacancy rate tightened to a record low of 0.3 per cent in March, down from 0.5 per cent in December, reinforcing extremely constrained supply and the sharp rebound in rents.
In Perth's housing market, the western suburbs dominated the top 10 most expensive suburbs for median weekly asking rents:
- Dalkeith and Swanbourne: $1500 per week
- City Beach: $1400 per week
- Mt Claremont: $1300 per week
- Nedlands, Floreat, and Cottesloe: $1150-$1250 per week
For units, North Fremantle, Cottesloe, Claremont, Perth, and Subiaco topped the list, with prices ranging from $750 per week in Subiaco to $885 in North Fremantle. Notably, North Fremantle's median rent was the state's most improved, despite a 0.6 per cent drop in prices over the quarter.
Affordability Becomes Key Constraint
Domain's latest report, released on Thursday, reveals that the national conversation has shifted from how tight the rental market is to how much more renters can realistically pay. "Rental conditions still favour landlords due to the lack of supply, but the pace of growth is not being sustained at high levels," Dr Powell said. "This isn't because conditions have eased, but because renters have hit their limits."
She added that affordability is now the primary constraint, limiting how far and how fast rents can rise, even in the tightest markets. "This reinforces the shift in the cycle, where tight supply is no longer sufficient to drive faster rental growth. Markets such as Perth, Adelaide, and Hobart remain extremely constrained, while previously softer markets like Melbourne and Canberra are tightening again. This confirms demand remains strong and supply insufficient — but the price is becoming more uneven and less responsive."
Broader Market Trends and Future Outlook
Across other capital cities, Brisbane continued to record steady gains, with momentum consistent in the unit market but moderating for houses. Sydney held its peak levels amid extremely tight supply, Adelaide recorded uneven growth and seasonal spikes, while Melbourne was still working through a recovery phase.
Domain stated that these conditions mark a defining shift in Australia's rental market. Renters are increasingly seeking cheaper locations and house-sharing, becoming more price sensitive, slower to commit, and more willing to walk away when rents outpace their incomes, even in tight markets.
"Supply remains severely constrained and competition remains fierce, but tight conditions alone are no longer enough to push rents higher across the board," Dr Powell concluded. "Instead, the market has entered a new phase — one where renters' budgets, not just the lack of available homes, are determining outcomes and increasingly shaping major life decisions, particularly for younger Australians deciding when to move out of home and where they can afford to live."
