Centrelink online services are accessed through a myGov account linked to Centrelink, where you can make claims, report income, check payments and upload documents. Keep your myGov sign-in details and security codes private, and only use the official my.gov.au or servicesaustralia.gov.au websites. Check reporting dates and payment details carefully, as Services Australia assesses claims and updates based on your individual circumstances. If you have trouble linking an account or understanding a requirement, contact Services Australia directly for help.
