Being a rumour network, I thought that I would add this one.
I recall that when NJS was bought by FR aviation of the UK, a number of posts on Pprune indicated that the new owner was really only interested in NJS's subsidiary company that had the lucrative Coastwatch contract. If there is any truth in that line of thought then the current topic of Airconnex flown B717's replacing the NJS 146 services might be the ideal way for FR's Australian subsidiary to withdraw from commercial RPT aviation and concentrate on its core military and para-military business.
