I am in WA first 2 weeks in May coming from prime kiting season here in Scotland but at least it will be warmer - sounds like you had a lousy season - any chance of wind ? I will be bringing a foil and maybe a foil kite if its really dodgey - any tips on where is best - looking to do a wee pilgrimage to Margaret river but other than that looking to see the sights and do as much surfing and kiting as I can
In Perth we tend to struggle to find wind in April, May is even harder. Having said that I am on a twin tip and the foilers tend to get a lot more kite time. As Psychojoe said, north is probably more likely.
