During my two plus decades living in PNG we had pilots from all four corners of the world. Canadians, Yanks, Kiwis, Poms, Aussies and from a smattering of other European and Asian countries.
But none had only "250 hours EASA CPL/IR holder with an FI rating". Any irresponsible PNG operator that gave you a start with that little experience has no rightful place in the PNG aviation industry.
With those hours you won't get a hearing and are wasting your time and money going to PNG.
