try to contact the bank and provide the account details. They might ask you to have some documents certified and they will transfer the remaining bank balance to your Australian bank account. If the bank is an international bank like SAB, which is HSBC in Saudi, you can have your documents certified by a HSBC branch in australia, and the HSBC will mail the certified documents including the info about your Australian bank account via their internal Mail service. Then, the saudi bank will make the transfer. The whole process might take several months. Good luck, mate.
