I was thinking the same thing recently. But I decided to hold off for a little while, as interest rates didn't end up going up this month. Interest rate hikes always make our dollar stronger, as foreign investment in Australia (and then obviously demand for our dollars) is increased...though I'm not sure how long it would take to take affect? And then some experts say our rates will increase up to 5 times in the next year.
On the other side of the 'coin', I'm slightly confused at how the Aussie Dollar is high this time around compared to previous times. When it was high in the few years, it was overpriced compared only to the US Dollar. Now it really seems like we're high in comparison to everyone (Euro is now around 70 Euro cents, Pound is about 60 pence). Crashes came due to foreign crisis (GFC, then Greece), as everyone rushes back to the greenback in tough times. Are we genuinely overpriced? Or is demand for our dollar this time genuinely justified?
