Links to Flying club in Vanuatu. Three ex/current Instructors are up there. One on a twotter the other two instructing and ATO's. Used to have links to Sunair, a piston twin small airline. Not too sure if that still exists though. Island Air gets pilots from Bayflight, they fly a 172, 206 over to the great Motiti Island.
Was over there last week and saw a heap of students. Good thing is that you have an abundance of instructors. Suppose that is the same as anywhere. They have one 'A' cat (owner), 4 or 5 'B' cats and a handful of 'C' cats.
They have 6ish Cessna 152, 1x 172, Piper Seneca and a cherokee. Not too sure if the cherokee is still working.
They have accomodation on the airfield for students if you dont have some.
If you are interested go and have a chat to some of the students/ instructors. See what they have to say.
Good luck
