Don't know much about the Airline but it seems like a good deal which may interest some. Travel dates are 15 Sept 2014 - 31 Mar 2015. Takes just two hours where most others seem to be at least five with one stop.
Edit: Ad came up for Skyscanner for $553 return. It took me to travel.com.au and found ticket for $556.90
These days you can get an all expenses cruise to Noumea and the pacific islands for that price. But I guess not bad if you want to spend a bit of time there and return when you want.
