Property in 2025 + Record seller profits + Population past 31 million
Three capital cities dominated the property market in 2025.
Darwin (18.9%), Perth (15.9%) and Brisbane (14.5%) recorded extraordinary price growth during the year – well above the national median of 8.6%, according to Cotality.
Darwin’s surge is a relatively new one – the city’s median price barely moved in 2024 and has increased 38.3% over the past five years.
By contrast, Perth and Brisbane have been running hot for much of that period, with prices up 89.0% and 86.7% respectively.
Most commentators expect home values to continue rising in 2026, although the pace of growth is likely to depend heavily on interest rate movements and borrowing conditions.

Property sellers post record profits
How much has owning a home really paid off for Australians? New Cotality data provides a clear answer.
In the September 2025 quarter, Australians who sold their home for more than the original purchase price recorded a median gain of $335,000 – the highest profit on record. By contrast, those who sold at a loss recorded a median loss of $44,000.
One of the clearest patterns in the data is the link between time in the market and outcomes. Sellers who held their property for less than two years made a median profit of $132,000. That figure rose to $361,500 for those who held for up to 10 years, $496,750 for up to 20 years and $843,000 for sellers who held their property for more than 30 years.
Overall, 95.5% of vendors sold for a profit, while 4.5% made a loss.
While individual results always vary by location and timing, the data highlights that property tends to reward patience, long-term thinking and sensible financing structures.

Population set to climb past 31 million
The federal government expects Australia’s population to reach 31.5 million by 2035–36, up from 27.5 million today, according to the 2025 Population Statement.
That’s despite a projected slowdown in annual growth to 1.3% in 2025–26, as net overseas migration normalises.
Even at that rate, more than 330,000 people will be added each year – a figure well above current levels of home building.
This gap continues to place upward pressure on rents and prices, particularly in cities with strong population inflows like Perth, Brisbane and Melbourne.
Unless construction activity lifts significantly, the gap between housing supply and demand will keep widening – making affordability an even bigger challenge over the decade ahead.
