All online credit card payments are subject to a percentage surcharge as charged by the bank. You will need to calculate this surcharge and add it to your payment.

Alternatively, to avoid the surcharge, please use NetBanking for payments within Australia or TransferWise for international payments with low transfer fees. 

 If you still prefer to pay via credit card, please add the following percentage to your payment:

1.4% + 30¢ for domestic Visa and Mastercard transactions
1.75% + 30¢ for domestic American Express transactions
2.9% + 30¢ for all international transactions
