Curious,
As I mentioned in your previous post, ring CASA PNG and obtain all the facts. Do not rely on here say and gossip
I'll make it easy for you: ring Capt. Malakai (CASA PNG FOI) on number +675 7141 5521.
It's so easy. Yes CASA PNG do recognise other ICAO ATPL and CPL theory exams BUT they will not issue you with a PNG CPL or ATPL licence or temporary validation until you have a employment.
CASA PNG do not have any means of administering a flight test! They rely on your employer to do so on their behalf. For other than PNG Nationals you have to be over the of 23 yrs (to encourage locals to obtain licences) and have a minimum of 1000 TT to fly on commercial ops in country as PIC, or something to that effect.
