I am in NZ, not AU. I have a pacemaker. By having it, over here it automatically suspends your medical, but it has been so long its expired anyway. They need to be updated every few years. When you renew your medical it will ask you questions re: heart issues and they may refer you to a specialist to have test carried out mine were $1,100NZ not including the CAA fee and the CAA medical. It was just the cardiology visit.
