I made the very naive mistake on my initial Class 2 issue of disclosing a mental illness which I suffered from in a finite period of time as a teenager, and the fact that I'd had LASIK - despite getting a near perfect core in the vision test. The total cost to confirm that these were not in fact current aero-medical issues ended up being over $1000 out of pocket. The aviation opthalmologist and psychiatrist that I had to see to certify that I was not visually impaired or insane both thought it was a ridiculous waste of time.
This initial issue was under the long-gone Dr Navathe's regime. Repeatedly calling them for updates only to have to jump through more hoops almost drove me to tears. I will make the point since then that my renewals have been straightforward and I saw a DAME2 for my last who issued it on the spot - it seems not all DAMEs have this 'accreditation'.
All of this to say I am convinced that the research cited in this thread earlier is correct and that there are many, many Class 1 or 2 holders that a) withhold information from their DAME and b) would never see their DAME as their GP.
Briefly scanning through the 420 FOI stuff that Clinton uploaded also makes me wonder how many of the people who work in CASA can actually go home and consider that they've done a solid day at work improving aviation safety...what a waste of our taxpayer dollars.
