TurtleHunter said..Simple - fly to Exmouth, hire a fully self contained Camper Van and camp at Osprey Bay, 2 minutes from Sandy Bay in Cape Range National Park.
Make up your own itinerary as you feel on the day. But calling you will be kiting by lunch time and drinking beer by 4pm

Flat water and waves = yes!
Going outside of school holidays and during the week, would you be the only one kiting, or likely the only one on the whole beach?
Looking at google street view it looks pretty barren and deserted. Which is great, but I would want at least some other kiters to get help etc.
Im thinking of doing a solo trip somewhere as soon as uni is over...
