Let us all also bear in mind that the US is NOT our sole trading partner by any means & a free trade agreement does interesting things to offset $AU upward movements. There are many tariffs at more than 40%.
And don't neglect that a global economic upturn would also lift Australia's economy and help offset domestic pressure on the housing sector.
Also don't forget the massive ROI opportunity for US investors of being able to pour money into Australia,with a higher interest rates & lower dollar (not to mention Europeans or Japanese for that matter)...
There is an enormous opportunity for Australia right now, but it seems a lot of people are focused on the micro and not looking at the macro.
