Mach E Avelli,
Oh, and how about some bedside manner here? "a load of complete rubbish" indeed......
Bedside manner has nothing to do with it.
I love a good CASA bashing as much as anybody, but what you wrote was just completely wrong, and obviously designed to be misleading and adversarial. The information is available from the main "Aviation Medicals" page on the CASA website. It is hardly a "close secret".
I still am not sure what you meant when you said that there is a luxury in always going to the same DAME. While I think that sticking with the same Dr, whether it is your GP or DAME, is a good idea; I'm not sure how going to a different DAME makes it difficult to know the age requirements. I would genuinely like to know as it may be something that will help me in my practice. I see a lot of itinerant pilots.
