Divingduck ... you hit the nail on the head ... not just for generic endorsements, but for everything aviation.
It is often quoted that such and such works in Timbucktoo ... why can't it work here?
For instance, Ireland is about 70,000 sq kms ... the same size as Tasmania.
Having genneric endorsements for high level Tasmania seems quite plausible.
But when you compare a whole country with a whole country (without allowing for geography, size, demographics, facilities, weather etc) ... that's when it gets tricky.... a la NAS.
