no Oz experience
yo man
I suspect the radio calls/procedures would be the best to study before you start if you do not have Oz experience. One of the points strongly emphasized to trainees is to know their AIPs. Your line training will be thorough, but if you can cut out having to learn new comms procedures at the same time, it should reduce the workload.
Often the only way others, outside the cockpit, can judge you initially is by the standard/tone of your voice on the radio. A few within need to improve theirs.
Good luck
