I have kited up they on and off for 4-5 years.

Kite sizes, 15m, 10m and 8m freestyle kites. If I was to just have 1 kite it would probably be a 10-12m depending on weight (I'm 70kg).

Check willyweather for the 5yr average but remember the wind up there is not nearly as dense. ie for me 20knots in Perth would be 10m for sure but up there its 12-15m weather.

It is windy almost all year round and the spoil bank allows u to kite in either direction without any wind interference. Another place that is good fun is pretty pool in northerlies.

Wind is more consistent in summer (lighter) and winter months. Have kited the 8m quite a lot during the morning winter blows and usually always got out in the arvo for summer sessions.

Tide can also be a bitch

Thanks for the advice, I look forward to getting started! And yeh it is a great place to live apart from the fifo clowns who know better!
