To activate an Australian SIM can be a bit tricky too. The easiest way is at the airport's where you find the major brands Telstra, Optus and Vodafone and a few MVNOs by showing your passport.

It's more difficult with online registration for the brands sold in supermarkets. Here they use a verification system through your credit card. But some foreign CCs which can't be tracked down to a specific person/address are declined.

So I'd suggest to do it at the airports where they have the same offers for the major brands as in stores and stay away from brands like Aldi's. I don't think that you need to show your visa, but expect to show your passport and online your credit card data.
