There is generally no fee from Services Australia for submitting a Centrelink report. Reporting through your myGov account or the Express Plus Centrelink app usually avoids phone charges, although your internet or mobile provider may apply its own data costs. If you report by phone, the call cost can depend on the number used and your phone plan. Check your reporting options and any current contact details on servicesaustralia.gov.au, especially if you are unsure which method applies to your payment.
