Firstly, AusDoc, don't insult a man by calling him an "economist". Thems fighting words. Especially to an American.
Yes, we hate our "so called economists" as much as everyone else. It's why the economy normally works better when we don't listen to them.
It's worse that anyone actually listens to them. Then again, we're so used to Europeans telling us what to do, that I think it is the way our "economists" can get back at them. In the "well, THEY listen to ME" passive-aggressiveness.
As for the Australian Economy, there's two different aspects. The Housing Bubble and the Economy as a whole. I'd definitely be "long term Bullish" on the Aussie Economy, as a whole. Small population, monstrous amount of land, huge natural resource supplies and livable weather in enough of the country to support its own food production. (It's a net food exporter, in fact)
Add on that Sydney (and to a lesser extent Melbourne) are important financial centers in SE Asia, the RBA seems the only central bank that isn't "hopped up on goofballs" (this isn't an endorsement of their quality, but you're King of the Blind with 1 Eye) and I really am quite Bullish on the next 20+ years of the Australian Economy. This also assumes your government doesn't start taking crazy pills.
All that said, even as the "major" cities become financial centers, which will keep their real estate prices higher, there's always an eventual correction to reality. Which is why I said "You always have to pay the piper". What can't continue forever simply won't.
For Aussie housing, probably the two graphs I'd keep an eye on are these:
Exports as a % of GDP &
Ores & Metals as a % of exports. It's the reason I'd be both "long-term" Bullish, and medium-term expecting a housing correction. Global asset prices always have a Boom & Bust cycle. The next one would be the likely catalyst for an Aussie housing correction.
The upswing is that Chinese & SE Asian demand for Aussie goods probably never goes away, to any large extent. The value of those goods, however, can drop a lot. This is the problem Canada has. Crude Oil getting back to $50 should be what blows up their Market.
As for China, tea leaves & voodoo would probably be more useful than analyzing their "statistics". But the warpath they've been on is going to run into the problems of lowering US demand in the second half of the year. Being the American, I do get an up-close & personal view of the "facts on the ground". ;D US "core inflation" is low. Practical? Pretty dang high. Food prices are up massively on the year, Gas is again quite high, and the only reason we've "recovered" is Natural Gas & Oil in the Midwest. Plus funny money on Wall Street. This will carry over into the end of the year & Christmas retailing.
This is also part of the reason I've come to view "Core CPI" as a complete fiction. It reflects so very little about the actual reality of situations. Even when making an argument for "fundamental" aspects.
In closing, as I said, I'd be long-term Bullish on the Australian Economy. Great place to invest... just not in real estate at the moment. >
At the same time, it does take a while for Real Estate bubbles to explode. Before the GFC, the US retail market peaked in Summer 2005, while the residential peaked in Spring 2007. It took a lot while for the economy to respond to those peaks. So, there's still time. I just wouldn't want to be caught holding the cards during a correction. ;D
