If you are intending on working in Australia, it will be a good idea to set up your own bank account. This is relatively easy to do provided you have the correct identification (passports, birth certificate, other credit cards etc.)
Once you have opened your own account, you my access most Automatic Teller Machines (ATMís) around Australia, 24 hours a day, 7 days a week. Even if you have not opened an Australian bank account, most ATMís around Australia
accept Visa, MasterCard, Diners and other internationally recognised names.
