Weekend financial review had a good piece on this last weekend, going over all the info above. American dollar is weak and Aussie falls in a heap as global economies fall and demand for our commodity exports falls.
While our dollar may strengthen a bit as things pick up, American dollar probably has a lot further to go up. Most analyts predicting therefore med-long term Aussie of about 55cents (or even less) against America.
So, if you've got the money, next few months may well be time to buy with prices 30% dearer in long run.
(assuming the analysts know what they're talking about, which is questionable as also noted above....
