NJS were an established Hi cap operator of some 15 years in the Oz industry , slightly different situation to Skyair I would have thought, who are a new start ( ok, with a few familiar faces maybe ) with a first of type in the country.
Also lets not forget NJS had a " little " help from Jetstar who had operated the A/C for years and NJS were not able to do without the support of a certain Jet* checkie for well over 12 months.
