Thanks a lot, moonboy1!
I'll stay from 10 Sept til 06 Oct, do you think there will be a realistic chance to have some good sailing conditions (e.g. also around Geraldton)? As far as I know the more North I go the better the chance for wind, am I correct?
I can imagine that you are not really keen on Non-Ausstralian windsurfers visiting your home spots, do you? On the other hand I am a kind of windsurfing dinosaur

that enjoys traveling to scenic spots around the world and I have experienced a lot of hospitality in most of the times. Your quick response is another proof for that.
The first 14 days of my stay will be for sightseeing and for my girlfriend.

So I am going to spare you and the other guys during that time.

Do you have any other recommendations for camp sites along the track Perth - Gnaraloo? Where could I have a good starting session?
Thanks again,
Michael
