If the billing location is relevant for the fees, one would assume that consumer protection legislation requires to display the billing location before the transaction is approved. Whether all foreign businesses will follow the rules is another story. But if no such rule even exists that seems to be a gap in Australian consumer laws. (And as a sibling comment indicates in the US. But the US is generally more business-friendly than consumer-friendly, so I am not surprised.)
