The investigation identified that medication the left seat pilot was taking was not recorded in his medical file.
While not stating this as a contributory factor, the report mentions twice (p.4 and p.24) that the pilot's DAME was unaware that he (the pilot) was taking a prescription medicine.
Are the ATSB really that naive? Given most of the pilot group now think of AvMed with distrust and contempt of biblical proportions, are the ATSB really unaware that the "tell your DAME nothing" attitude is prevalent?
