If you have been granted a total exemption from Total VET Activity reporting then you are exempt but only for 2015. From 1 January 2016 this exemption will apply only to training for which you have received no fee or any other form of remuneration or consideration. Further information and help is available from Australian Skills Quality Authority (ASQA), Victorian Registration and Qualification Authority (VRQA) WA Training Accreditation Council (WATAC).
Note: If you deliver courses over one day (or less) before 31 December 2017, you are able to issue a qualification or SoA to students who do not have a USI on the day. You do not need to apply for a USI exemption in this case. However, you still have to meet the reporting requirements.
