A standard 20Gb iPod sells for A$439 retail.
40Gb iPods are being discontinued, but if you can find one, you’re likely to pay around A$479. Which given it comes with a dock that the 20Gb, makes it a bargain.
I just found one for $449 at ht.com.au, which makes it an utterly completely irresistable bargain. So I bought it.
