If your driving up bring your gear with you, nothing to hire,
Also if your driving keep going past the Airlie turn off and go another 45mins to Bowen, Airlie's wind is very shifty and land affected, Most of the Kiter's in Airlie come to Bowen every weekend.
You might be able to hire some resort gear on the islands but if you want to do some serious windsurfing Bowen is the go, We have moderatley flat to great bump and jump and small wave conditions,
I don't know of any regular windsurfers in Airlie but there is any where from 2 to 8 of us here in Bowen, plus the gays on trays.
