Start by arranging mail redirection with Australia Post, then make a list of organisations that need your new address. Update your details with your bank, employer, insurer, energy and internet providers, medical practice, electoral enrolment and any subscriptions. If you receive Centrelink payments or services, update your details through myGov or Services Australia, as your circumstances may affect what information they need. You may also need to update your driver licence or vehicle registration with your state or territory authority.
