When the Australian dollar was down on the US, ~50-60c, the prices didn't seem so out-of-whack. Now that it has risen to 90-100c, it seems crazy. The prices have stayed around the same, rather than dropped as you might expect. The exception is real estate, which grew at 30-40% some years in the noughties, an industry so distorted that if it doesn't grow by 10%/year now, analysts run around claiming the end of the world.
