"So if it's not a bubble why is Australia most expensive plase to live on the world."
Who cares - plenty of people can still afford it if they are reasonable with their expectations.
"It's not population as we have a ver small one, it's not population growth as it's very low historicly, and it's not new population buying new houses which we can see from mortgage results it's all investors."
Who cares what our population is the only real thing of importance is the ratio of houses where people want to live to the population. And before you say it it is not investors hoarding houses as the vast majority of houses owned by investors are available for rent so the owner can make money. The majority of the vacant houses are where people currently don't want to live (i.e. country) or are holiday homes.
"I assume u know the answer to know it's not a bubble? "
History will tell us this answer, but many have been calling this so called bubble for 10 years - which is years of lost opportunity. To date there has been no information presented here (that cannot be disputed for one reason or the other) that there is a need for the whole market to collapse to make housing more affordable. Buy with a long term plan and whether it is a bubble or not is irrelevant.
