Start by checking which payment may suit your circumstances on the Services Australia website, then sign in to myGov and link a Centrelink account if you have not already done so. Select the relevant payment, complete the online claim and upload supporting documents such as identity, bank, income, residence and relationship details where required. Some payments allow you to register an intent to claim, which may affect the date your claim can start. Services Australia assesses each claim individually, and you can check your claim status through myGov or contact them for help.
