The Age Pension is assessed under national rules, so living in Sydney does not create a separate payment rate. Services Australia considers factors such as your age, Australian residence history, income, assets and relationship status when assessing a claim. You can claim online through myGov, linked to Centrelink, and should check the current eligibility rules and payment rates on servicesaustralia.gov.au. Your actual entitlement is determined by Services Australia based on your individual circumstances.
