Bleusaille - ahh. Most Bush flying gigs in Australia really don't pay well and is hard work. However, there's opportunities for float flying. Biggest obstable re Oz and NZ is the right to work etc. Relatively easy to convert a licence. Now, I think the Maldives use Float Twin Otters and Canada have a lot of aircraft on floats and skis. I don't know anything about operating in Canada.
I have a friend who's working in the Reunion Islands in the Indian Ocean. He's working for Air Austral and now that looks like a really chilled gig. He loves it and it looks like paradise
