Yes Sydney, Harbour Bridge, Opera House and Centrepoint Tower (or whatever its called now) are all visible. also i really hope its not Oslo-Sydney nonstop, i'd self destruct
I don't think even the great 777-200 LR can handle this route non-stop (routinely). lol Besides, setting up a mid-point stop (At places like New Delhi or Hong Kong depends on the route) can generate so much more traffic for Norgeflyg's flights.
Edit* If it is non-stop, I would as well.
