MarketPress - Stripe Australian Dollars

I just got an invite to the Stripe Australian Beta and would like to start testing on the MarketPress plugin. My invite from Stripe only allows for USD, Euro, Canadian and Pounds, so wondering what I need to do to activate "AUD". This is the error message I get when trying to test the current setup.

There was an error processing your card: "Invalid currency: usd. You can change your account to process transactions in usd by adding a bank account for this currency at Your account currently supports these currencies: aud.". Please go back and try again.
