The conditions should be good at that time of the year but who knows, the season just gone was crud.
As Aseela said, Lancelin YHA Lodge is the best bet for accommodation if hostels are your thing. Otherwise two caravan parks and a pub/hotel. There is usually a regular crew of kiters and poleys staying at the Lodge by then.
Although I learnt here, Eddie Island Point where most of the kiters launch from isn't the best for learners/newbies as you are directly upwind of the windsurfer park, also add in the shallow reef on the outside and cray boats moored downwind of the windsurfers. Midweek you might get away with it but on the weekends it can get crazy. If you come, as always find someone that kites and lives here or find a regular from Perth to help with the do's and don'ts and where the hazards are.
A kite school (Makanakai or something like that) runs from the point at the north end of town. North Point isn't the most popular with the kiters as its tucked out of the way but there is nothing to run into and the beach is pretty quiet. It's worth considering if you want room to flail around without a big audience
Cauncy, you're not far up the road, I might have to pop up next season for a peek
