Been going to dirky for 14 years , certainly one of my fave spots to visit, we caretook the island one year at Christmas , it's internationally renowned for its amazing fishing, as for kiting, the loop is a great flat water spot which works best in a swester, the razorback dunes are testament to how the wind funnels down to this spot, easterlies and westerlies aren't worth it, surf point can get insane in big swell and a swester, I wouldn't advise getting into trouble at this spot, homestead is ok from the east ,it's a very unique spot to visit and well worth a visit, Kieran and Tory do a great job, you can also fly over with Denham scenic flights, however any decent rain this time of year can make the airstrip unusable, doing the barge and taking your own 4x4 (decent) really opens up your possibilities,
if a keen surfer, urchin point produces insane waves,

The tuna was speared in 3 mtrs of water in front of homestead, George the 4 mtr tiger shark was just north of where your kite was parked, a mate( non kiter) counted 50 shark fins at tetradon , heaps of pinkys in close,
The whole shark bay region imho is a spectacular spot to visit
