Centrelink online services are accessed through a myGov account linked to Centrelink, allowing you to make claims, report income, check payments and update your details. You may need identity documents and supporting evidence, and should keep your myGov sign-in details and one-time codes private. Online reporting and claim deadlines can affect when information is processed, so check your tasks and messages regularly. Services Australia decides eligibility and payment outcomes based on your circumstances; use servicesaustralia.gov.au or contact Centrelink if you need help.
