Yes, we transfer your refund to your overseas bank account for additional $45 fee. St George bank charges $10 bank fee and your overseas bank account may charge the fees for transfer from overseas. Currency exchange rate is St George bank's rate at the tranfer. Due to these fees, we do not recommend that you receive the refund into your overseas bank account and it is recommended that you leave your Australian bank account and close later.
Alternatively it is recommended that you should use TransferWise for better currency exchange rate.
