As far as I know if you have 3000hrs command time on a jet over 30ton MTOW you only have to 2 JAR exams Air Law and Human Factors plus a sim ride on appropriate aircraft . If not all 14 exams need to be done. Expensive and time consuming. Initial issue of a JAR medical can only be done through a couple of places in Europe. Once gained medical can be renewed at select doctors here in oz. It is possible to get a JAR validation on Australian licence to fly for 12months.
