Guys,
The reason the medical costs are so high is that the doctor who becomes a DAME has to pay out of his own pocket for the course and examinations to become a qualified DAME.
The DAME course costs approximately $15K. So to actually get any of that money back, most doctors charge a motsa for the medical examinations. They probably are lucky to do more than about 2 a week (if that). Plus they have to stay current, which also costs money.
If you're in Brissie, Dr. Chaffey (Camp Hill Medical Centre) charges about $150 for a medical.
