remember that if you fly business class international with quantas at SYD airport, you can check in at a dedicated private area at the end of the terminal.
It is a little like first class terminal at frankfurt : private check in, private security, and the lounge entrance is directly connected right after the security !! that is cool for just business class service
The food at air calin biz class is average, surprisingly for a french airline.
the seat of the flight air calin SYD-NOU is non lie flat, recliner comfortable for a short 3 hour flight
quantas and their partner, air calin does accept reward points booking with AVIOS. and since the distance is short, avios rewards is worth it. It cost 20000 avios plus $235 tax and fees for business class ticket one way per person. Compared to min $1000 usd pp one way.
