Back in the day, when NSW maritime as they were known then, approached NSWKBA which was the state association of AKSA (now KA and KANSW). They contacted us due to the actions of the large bald guy, who had a little bit of hair back then and a similar amount of aggro attitude, and his look at me buddies. Bald guy lives in Point Piper so thinks he has local rights and can kite wherever he wants disregarding rules and the safety of others. He also kites at Bondi, which is also a location where kiting has been banned. (second most visited tourist location in Australia, always crowded even in winter) One of his mates was on the infamous Bondi rescue show getting dragged up the concrete wall at the back of the beach. Big baldie has been knocked senseless by a well known ironman personal trainer for harassing surfers and giving lip.
He had been in trouble with Maritime prior to kiting for windsurfing in the "no go" zones and regularly told Maritime officers to feck off. Besides that bit of background it was decided after several meetings that kites would be banned, due to incidents with kiters (those crew) needing to be rescued, and flying too close to the seaplane zone. KSWKBA had to support the ban because we knew that a downed kite with 27M of lines was a massive safety issue for the person attached to it and any passing motor boat or yacht. Sydney harbour is an incredibly busy waterway, large commercial craft, with limited ability to see or avoid a downed kiter, and zillions of other boat owners with widely varying sobriety and navigational skills.
Its also a crap place to kite and is incredibly gusty with no safe downwind margin for error.
There was a thread on here about this time 2/3 years ago from big baldies mate, he was lofted and knocked out, and thought he had been drugged, it was a pretty strange story, some people never learn.
