After many years as a professional economist and strategic consultant, I know better than to try to predict the market. Still, both my wife (she is also an economist) and I blinked at the current decline in value of the Australian dollar as, and I quote, a "risky" currency.
Australia's economic fundamentals are some of the best in the world. Yes, local interest rates will fall, but so will they elsewhere.
Still, one should not complain. While the decline in the aussie will add to local inflationary pressures, it will also provide gains to exporters while discouraging imports. That's not a bad thing just at present.
