I know of one Kiwi in GVA and of another who didnt make it.
You'll have to brush up on french as I had to really battle my way around GVA in english when I was there on an instructors course.
Otherwise we're a large group of Danes and another group of Swedes and Germans. Very international team in ZRH.
Only 2 South Africans....but hoping for more!
Dont know much about GVA though.
Cheers
