Just something to consider.
In the early 90's 2 good friends and co-workers won a position in PNG flying a Bandit & Otter respectively. The flying was great and exacting, alas Malaria bit both of them and cost them the opportunity of major airlines. At least twice a year they are grounded due to a bout of the bug and on numerous occassions have lamented going there. The rest of us managed to progress upward.
There are some very very professional Pilots in PNG and it is a tragedy that medical issues prevent them from progressing.
Consider all angles before accepting a position in PNG and always go with the gut instinct, it is there to guide you!!
