Lesson 1. Do not refuel the aircraft so it's chokkas and then fly a short leg to Fraser Island. It will be hairy trying to take off when it's time to leave! (unless you find a fisherman who will be happy to relieve you of 50 or more litres of avgas to run his generator). The Orchid Beach strip is short, soft and sandy, and the wind will most likely be tail wind/down hill or into wind/up hill. If you want the strip details, send me a PM.
