No, sorry

Unfortunatly not, CASA has ruled against this occuring. The case mentioned above not whistanding and the fact that the FAA(?) do allow some forms of daibeties for aircrew.
I know of a guy who developed type 1 as a mature adult, he lost his medical and subsequently his ATC rating. Mature onset type 1 is very nasty and you really should get some very good advice from your doc. My friend in the example above ended up loosing something a lot more valuable than his ATC rating!!
Pilots with Type 2 Diabeties are almost always restricted to two crew ops, where the second crew is endorsed on type. Basicaly as mentioned above.
I strongly sugest taliking to a DAME or give the CASA Medical branch a call and discuss it.
