You usually do not submit a separate Rent Assistance claim: Services Australia assesses you when you claim an eligible payment or update your accommodation and rent details. You can provide this information through your myGov account linked to Centrelink, or contact Services Australia if you cannot do it online. You may need details such as your address, rent amount, landlord or agent information, and a lease or rent certificate. Eligibility and any payment are decided by Services Australia based on your circumstances, so check the current rules at servicesaustralia.gov.au.
