Whatever visa you have a student or Permanent Residency or Temporary Graduate or Work Visa, your personal information such as name, date of birth, Address, Tax File Number, driving license as well as credit card details and MyGov details are very important to you. Information on those is used to identify you, for example, your name, address and postcode might be enough to reset your opal card password or bank card pin or someone can get access to your internet banking using information on your driving license.
