Adelaide houses are impossibly unaffordable. Less affordable than London, New York, San Francisco, or Los Angeles.
Adelaide homes sell for a median multiple of 11.2 times household income.
When the median house price is divided by median household income, it produces the median multiple figure.
In 1987, the median multiple for Australian houses sat at 2.8 times income. In 2026, that multiple hit a whopping 11.2!
The median multiple is an imperfect measure of affordability because it does not adequately account for factors like the changed cost of borrowing, but it does remain a widely used measure of global housing affordability.
According to the Demographia International Housing Affordability report, affordability can be categorised as follows:
3.0 & under : Affordable
3.1 to 4.0: Moderately Unaffordable
4.1 to 5.0: Seriously Unaffordable
5.1 to 8.9: Severely Unaffordable
9.0 & Over: Impossibly Unaffordable
Many cities in the USA, Canada, Singapore, and UK have median homes selling for 3 - 5 times household income.
How does Australia compare?
Sydney: 2nd least affordable in the world at 14.0x
Adelaide: 4th least affordable at 11.2x
Brisbane: 8th least affordable at 9.9x
Melbourne: 9th least affordable at 9.5x
Perth: 13th least affordable at 8.0x
By global standards, Australian housing is extraordinarily expensive.
Government has played a big role in creating this problem.
Lack of land release, massive taxes, fees and charges, repeated demand side stimuli, overregulation, unsustainable migration, and loose home lending conditions have all contributed.
The high price of housing has made many slaves to debt.
Two full-time incomes are often insufficient to purchase a home, even with a 20% deposit.
High house prices hurt renters just as much as homebuyers.
Shared equity schemes (with the government), 95% loans (guaranteed by taxpayers), and first home owner grants (paid for by taxpayers) all lead to higher priced and less affordable homes.
Higher taxes are not the solution.
Australian housing needs more land release, lower taxes, lower migration, less red and green tape, and far less taxpayer funded demand side stimuli.
