If you do the 206 or 182 rating in NZ, it is much more valuable for you in Oz, as no DZ is going to train you from scratch. I have seen someone do a 206 rating and about 5 hours total in it, go to Oz then pick up work straight away (not dropping though - charter work)
Even in NZ no one is going to let you loose in their 206 (especially if it's a turbo) unless you have had an instructor do a TR in it, and you have a drop rating. PM to discuss if you want.
