not sure but my take is that australia is the youngest most undeveloped most desireable country/island in the world and will stay that way for many many years.
i still have a report dated 2009 while the world was in deep shit that by 2015 the boom that the world saw before the gfc and what not will look like a little bubble.
they predicted housing prices to if not treble but atleast double by 2015 with the world to boom in a massive way.
imo i wouldnt be waiting for the aussie dollar to fall but hey im not an economist just a plumber so what i say probably means shit lol.
imho australia will become very strong in the years to come and very very expensive.
