“Since December 2008, real household disposable income has gone basically nowhere”, noted Brooker.
“Meanwhile, real housing prices have gone to the moon”.
“This is not a recipe for a healthy society”, he warned.
Brooker also created a similar chart from 2000, which is even more abysmal given the strong house price growth experienced in the early 2000s:

Collapsing interest rates over the 20 years to May 2022 (the RBA’s first rate hike) masked the decline in housing affordability.

In turn, analysis from AMP’s Shane Oliver, published in The AFR, shows a record gap between home values and what buyers can actually afford to avoid mortgage stress:

PropTrack analysis likewise shows that only 13% of Australian homes are affordable to the median buyer, the worst result in 30 years of data:

No matter which way you cut it, Australia’s housing affordability is the worst in history due to a combination of excessively high purchase prices and elevated mortgage rates.
