A myGov Centrelink guide can help you create or sign in to your myGov account, link Centrelink, and access messages, payment details, tasks and reporting. You will generally need your Centrelink Customer Reference Number (CRN) and may need to confirm your identity using details from Services Australia. Once linked, check your myGov inbox and Centrelink tasks regularly, as some payments require reporting by set dates. For the current steps and help with linking your account, visit servicesaustralia.gov.au or contact Services Australia directly.
