Australia really is the lucky country; Our floating currency

All I can say at this point in time is thank goodness that our currency is a floating one as the plummeting Aussie dollar will buffer our business here that export (including those that export commodities). This may be a simplistic view (I am by no means an economic wizz), but from a businessman's point of view (i.e. practical with holes in my theories), but I don't think the economic commentators have really paid enough attention to this. What do you think?
