Five now Jarden VH-INU (still on register till it is replaced by a new VH-INU), VH-NLK,VH-PNI, VH-VLI and VH-ONU That makes five now and in the future. Don't believe everything you read on Wiki it has more rumours than this site. VH-INU has not done its last pax flight yet and the ANZ aircraft are already owned by the Airline so at this point there is actually six if you want to get technical.
"where did you get the idea it is now 5?" From facts from the people who know and not Wiki
