Hey Matt, nothing you can really do to prepare for psych except to be sure that you know what is involved in your training and can demonstrate that you are prepared (separation from family, willing to fight for your country, etc)
For OSB, much of the same, be ready to be able to do some reasonably complex calculations in your head while under pressure, know all you can about the role, the training, RAAF in general, world events, etc, etc.
