Can't remember the route number but it was the main route used on SYD-HKG & MEL-HKG routes between waypoints Molly, Bonda & Ambon just to the east of Sulawesi. I believe that it was a QF (not ICAO) restriction on its own operations as a result of a risk assessment.

I find it bizarre that as the parent airline has assessed the route to be unsafe for night operations but the subsdiary airline is allowed to still use the route. That would indicate less emphasis on safety at the subsidiary - volcanic ash encounters are very dangerous. Other airlines that have I have heard using the route at night aren't known for putting safety ahead of burning 500kgs more fuel.
