Ace the Technical pilot interview is a good one. It will give you a general idea where your weaknesses are. Know your rules, download the AIP free from the CASA web site and just read it when you have finished read it again then repeat the process. Know all the relevant CAOs, again all free from the CASA website .Simple really.
Know your aircraft and give Pinstripe solutions a call when you get an interview.
Cheers,
Craven
