Okay this is what will happen

.
It is only a matter of time before someone hurts/creates danger for someone on the beach who has upper echelon connections. Or kiters puts themselves in mortal danger on a regular occurence - who knows how the the universe will roll the dice, but it will happen with the crowds.
Now kiting has far more potential for injury/danger than surfing. Surfing has never been regulated. But kiting can be easily equated with say the flog bag jet ski. Speed, momentum, lines, etc...
hence jet ski's are now given specific areas to ride in (why - I'm still trying to work that out - unless you are being towed in on a surfboard - really why?). You don't need a license nore do you need special lessons - too hard to police.
So kiting will go the same way. You say there is open ocean, will it is only open if there are no restrictions. This is obviously how councils will work. Political pressure from people with influence. You know all the guys and girls who attended PLC, MLC, christchurch, aquinnas , scotch etc etc. Those that know people, that know people. Don't be ignorant just becuase you are a nobody (like me), these guys have networks that get **** done!).
So areas restricted, kiters pissed, sport may decrease - for a while - hey canenvisage a mad chase between a crazy downwinder and the water police - ha ha that would be cool.
As for the melbourne dude, sorry to hear about your summer, but this is wa, there always will be wind. Even on the one of teh worst seasons since I began due to la nina, still had more wind than other states put together. It blows and it blow and it blows.... so your theory is faulty.
But what can we do? Really? What can we do?
