The Aussies just passed their cap and trade, did they not? Price of carbon something like $23 Aussie a ton, whatever that works out to. Actual market value: 5 American cents. The problem with overvaluing something that is detrimental (cuts in carbon) is that they will get more of it.
The AUS dollar has been higher than the USD, almost neck and neck right now, the unemployment rate is around 6.2% on average, some of the best rated places to live globally is in Oz.
the carbon tax does stink, and buying things like a new motorcycle in Oz after living in America will put a person into sticker shock.
