Hey Nik,
Greuzi is right, you better start up north and work your way down, there is no nice kiting in Perth in 2 months time for beginners. You should start in Exmouth and come down through Coral Bay, Shark Bay, avoid Gnaraloo (experts only location). Then visit Carnarvon and make your way down to Geraldton via Port Gregory.
Up north you will not need a wetsuit and you will need small kites. There are no kite schools up north. There is a couple of IKO instructors in Carnarvon that work part time, and one in Geraldton, thats about it though. It's all pretty remote up that way so you best be able to handle yourself reasonably well.
Like CAUTION says, contact the locals and find out the local dangers and do's and don'ts. It can be treacherous country to the uninformed.
Good luck and be good,
