Australia's housing market, like I'm guessing many others, is quite heterogeneous.

Sydney and to a lesser extent Melbourne are both completely unaffordable (A$1m+) to new home owners on an average income unless you're prepared to live in a unit or commute 2 hours a day to the CBD. Brisbane, Adelaide and Perth on the other hand are significantly cheaper and one could still afford a nice family home.

Also worth noting is that the huge boom in prices only really started in the early 2000s. People who bought prior to that period make up a disproportionate number of owner occupiers.
