JAA Testing Officer
Not 100% sure on the full deal, but I know the Western Australian Aviation College in Jandakot has just started JAA training, including integrated course, so am hoping they would have a testing officer. Give em a call.
In regards to the medical, as far as I aware (please correct me if I am wrong) you have to do the initial medical conversion in the UK (a scaled down initial for ICAO class 1 holders). And again, correct me if I'm wrong, but I am under the impression that this does have to be a JAA medical in order to sit the CPL test. I've found the CAA quite helpful, so maybe contact them.
