Entry requirements are flexible, depending on how desperate they are! In the past recruiting has been way behind the drag curve and won't start until crew numbers get critically short and flights cancelled, regardless of the ample notice rostering and the fleet captain's give them.
Upgrades have slowed dramatically from the past few years as expansion has slowed, looking at 3+ years now for a dash 8 classic command.
Right now flavour of the month with management is Moresby base. Only a govt owned business could get away with the logic of providing K10,000 a month in housing allowance rather than base crew in other domestic ports or overseas and commute them on company aircraft for a lot less than that a month. K10,000 soon won't be enough for a decent place either.
