The QBCC publishes an up to date record of all cancelled and suspended licences on its website which you can access here. The information is updated as at the time of preparation of this training, every 14 days.
The QBCC is obliged in most circumstances to provide notice (s 49 QBCC Act) prior to any cancellation or suspension. The most fundamental lesson for Module 4 is to NEVER ignore a notice from the QBCC or the passage of time will mean it is too late for anyone to meaningfully assist you.
