Idle curiosity here, but local knowledge will solve the problem.
If you are sitting on the beach at Wineglass Bay (in the middle of the 'cup') and looking out to sea, are you looking east or west?
I ask becos I have seen many pictures of this lovely bay and in some the curve is to the right, while in others it is to the left. They all seem to have been taken from the southern end.
Cheers, Tony
