The down-wind N-S & S-N runs are great fun - this section under the Noosa Council covers about 5-7 kms.
Council regulations have identified Kites surfing as per powered water craft (Jet-ski boats etc), and banned access, if you have not previously please read and consider signing.
FYI.. AMSA (Australian Marine Safety Authority) classification - kitesurfing labelled as a surf craft such as a surfboard, stand up paddle board.
