I do think Gold will head into an overvalued state against Australian property.
Gold is already overvalued. Gold is a relic, almost worthless to society apart from electronics (mostly non-recycled environmentally damaging small devices like cellphones) and in the production of shiny trinkets. There are plenty of substitute metals that can replace gold in those cases. Gold is unproductive and not income producing (no yield). Gold is highly speculative - the only reason to invest in gold is if you believe a greater fool will buy it off you later for a higher price. Gold production is very damaging to the environment too. I can't understand the attraction of digging up huge quantities of gold at great cost to the environment, and then locking it up in a vault. What's the point of that... who benefits? At least houses benefit society.
