As above AUD is really strong. (But I am biased being an Aussie.)
Most of our recent success is attibuted to the boom in China, we sell them heaps of stuff from the ground. (Coal, Iron Ore, LNP etc.) (Also the reason for the High Interest rates here.)
But we have very strong Trade, Military ties with the US too, not to mention Oprah likes us.

So, IMO, an investment is Australia is the ultimate Each-Way bet on China becoming even bigger, the USA getting out of its current mess, or both.
