(TWOTBAGS on PPRUNE)
I spent nearly 3 years barefooting it in the ‘dives a while back. If you are going to go you need one of two licence options
1) FAA with AMES on it … or..
2) ICAO with Float endorsement and Twin Otter.
There have been some issues in the past with Aussies not having the twotter on the licence before arriving in country.
Having said that a mate with almost zero float time got hired just before Christmas. He had nearly 3K hours and a lot of multi turbine before he got there.
