For a myGov Centrelink checklist, have your myGov login, Centrelink Customer Reference Number (CRN) if you have one, identity documents, bank details and relevant income or asset information ready. You may also need documents about your rent, partner, children, study or employment, depending on the payment or service you are applying for. Link Centrelink through myGov and follow the prompts, uploading clear copies of any requested evidence. Requirements and eligibility vary, so check the relevant payment page on servicesaustralia.gov.au or contact Services Australia if you are unsure.
