Tightslot,
That depends on how many rotations per week you have. If it's only once a week then it works out very crew inefficient, one of the reason why both BY and AIH stopped the AUS routes.
The last time BY and AIH tried this route the customers voted with their feet (and wallets). BA & QF offer the route for £500-£600 with only 1 stop and a route time of approx 22-24 hours. With 2 stops you are looking at getting on for 30 hours! Whilst premium cabins with extra legroom are available, the majority of the pax are going to be economy. It's gonna take 2 days for the body to recover from being that cramped. And bear in mind, pax complain about the lack of room on a 4 hour TFS!
