The same call for has been made with property for at least 20 years, but hasn't eventuates. So get over it.
As for the great Aussie dream it used to be a house not a big house 3 bed 1 bath 17 sqs that was the dream. Now the dream is threate room ensuites entertainer kitchens, plus pool I could keep going on.
It's not as simple as house prices where once more affordable.
It's just in places like meld 5 mil people live there compared to to 25 years ago 1.6 mil.
All I can say is half of you are living in the past and you can see why when you drone on about being to expensive. Well sorry move out to the sticks get a small house and you might find its not that expensive.
