G'day whirlybird,
Schofields are one of the better schools out at Bankstown. As mentioned above, you'd want to do Victor 1 with harbour orbits which will take you right past the opera house and harbour bridge. You've also got the blue mountains to the west of Sydney which are really nice.
Also, there are heli scenic flights which operate out of Sydney Airport and also float aircraft which operate out of Rose Bay.
You might want to post in the
Dunnunda & Godzone forums if you need more info.
