But I thot the current Australian boom is riding to some large extent the Asia Pacific boom, mainly China's need for resources which Australia is supplying.
That's not the way I read it. I have made the point regularly that the bubble in asset prices (RE is just an asset, it's utility is secondary in this climate) is a direct result of the world being awash with cheap money, originating from the yen and gold carry trades. The bullion banks had access to literally trillions of dollars @<1% via borrowing Yen from the BOJ or gold from central banks. Their biggest difficulty was finding enough creditworthy individuals/companies to borrow it off them @<5%. Greed being such a strong emotion, they let standards slip. Ergo: The Crunch!

On the lower left of the page you will see a chart of gold lease rates, currently about 0.35% for a year. If you can borrow money at that rate you don't need to be a genius to make the odd billion.
