Check that you meet the Age Pension age and Australian residence rules, then gather your identification, Tax File Number, bank details and relationship information. You may also need documents about your income, superannuation, investments, property, vehicles, other assets and rent or home ownership. Apply through your myGov account linked to Centrelink, and allow time to provide any extra information Services Australia requests. Your eligibility and payment rate will be decided by Services Australia based on your circumstances, so check the official requirements before lodging a claim.
