Qantas is also charging for duplicated bookings through their PayID payments system when booking a flight. I was recently charged $259.02 when trying to pay for a booking through their PayID system and have had very long waits on the phone when trying to resolve and I'm still awaiting a refund. If your PayID transaction fails in the process, your account is debited, however, the booking will not be completed and your refund will not be re-issued. Qantas knows about this issue but is failing to address it.
