Centrelink online is accessed through your myGov account, which you link to Centrelink using Services Australia’s instructions. Once linked, you can make some claims, report income, update personal details, view payment information, upload documents and read messages online or in the myGov app. You may need to provide identity and supporting documents, and Services Australia assesses claims and reporting based on your circumstances. Check servicesaustralia.gov.au for current instructions or contact Centrelink if you need help linking accounts or using a service.
