No. Your fees will not be deferred if you have submitted an electronic Commonwealth Assistance Form (eCAF) without a tax file number (TFN). If you are an eligible Commonwealth supported or Domestic fee paying student, your eCAF will be approved, but you will need to submit a valid TFN by the study period census date to have your fees deferred. 

If don't have a TFN, please see How do I get a TFN?
