I also had a few things picked up by my class 2 medical that I wasn't aware of that would have pushed me off the perch quicker than I hope for. Whilst the class 2 is a partial pain and yet another cost I could live with it if it was just the class 2 every couple of years. Unfortunately once you get pinged for anything the costs start to ramp up rapidly for what (my DAME and) I believe re excessive and duplicated tests. I have a perpetual cost to try and continue keeping my class 2 every year. This includes std class 2 medical, special trip to CASA rated optometrist for (what seems like) the same eye test that the DAME has given me (extra $250/annum) , special trip to the tredmill for a stress test and cardio report from a cardio who wants to know why I'm wasting their time when sick people need to be treated (~$600/annum), annual vampire test at the pathologist. And to get all of this done requires trying to coordinate appointments with specialists that can have waiting lists of 1-2 months.
So, as you say, it's a good thing that your DAME picked up on your hypertension (me too, I've forecast your future with and annual tredmill and cardio report) and 'a' visit to a specialist as directed by your GP is a good thing if they recommend it. But the change from every two years for an over 40 class 2 medical to annual and the ~$1k all up cost is just taking the piss.
Oh, just to rub salt into the wound, the last two years CASA have 'lost' the reports from my DAME and specialist causing months of delay. Last medical I did in December last year came through in May this year, still with an annual expiry date in December this year.
I'm used to the class 2 medical and every couple of years seems to be ok with me, if nothing else it makes me visit a doctor for a checkup and oil change, but if a DAME needs special training from CASA (and it's expensive training), why isn't the DAME good enough to say if I am dead or not? Why all the specialists reports?
CASA need to held to account to justify why specific requirements are in place and it should be part of their charter to unregulate themselves out of a role.
