Centrelink online services are accessed through a myGov account linked to Centrelink, allowing you to make claims, report income, check payments and read messages. You will generally need identity and supporting documents, and should keep your contact and bank details up to date. Payment eligibility and amounts are decided by Services Australia based on your circumstances, so check requirements and deadlines on servicesaustralia.gov.au. Use only the official myGov website or app, and be cautious of messages asking for passwords, codes or payment details.
