Apple Pay adoption in Australia has been slow because of tough negotiations. However, CommBank will be supporting the payment service starting in January 2019.
Currently you can order and activate a CommBank PayTag for your iPhone with a one-off fee of $2.99. CommBank PayTag is a small sticker, around a third of the size of a credit card. The PayTag is attached to the back of your iPhone, allowing you to make Tap & Pay purchases using your phone.
