to start to solve this problem, you (perth kiters, waksa, seabreeze) should use a standard problem solving technique, like the continuous improvement loop.
you can't solve anything by saying "too much", "euros", "tools", "scary numbers"
A) quick survey
1) get as much real data as possible on the problem.
- have someone at every beach every day counting kiters coming to the beach. and report on seabreeze: "today at 3pm there was 27kiters at this spot, there was 23knots. not much people on the beach, and there was15kiters at 6pm"
2) take the data and make useful graphs, stats. (on average on a windy saturday, there are 20kiters a scarbs)
3) analyse the data
4) publish the data.
5) act, change something
6) do it again
this real data would also be very useful for waksa to use with councils.
B) detailled survey
you could also do a survey of kiters on the beach (because not everyone is on seabreeze.) I don't think people would mind answering a few short questions after kiting (not before)
- where do you live, where are you from?
- which spots do you most often go to kite?
- why do you go to these beaches?
- what do you look for in a spot?
- which days of the week do you kite?
- how long have you been kiting?
- which kite school did you learn at?
- if you are from overseas, how long do you intend to stay in WA, how long do you stay in perth?
- how did you find this beach?
- which other beaches have you heard of?
C) published infos
I think it's quite stupid to avoid naming spots on seabreeze, because they are everywhere on the net. google "safety bay kite", and you get over a million answers.
all the spots are named and on maps in weather forecasts websites, seabreeze or other (and kiters are quite well known to use these very often)
even if overseas kiters didn't know where the spots are exactly it wouldn't keep them from coming when they see photos, videos of kiting and weather data. they would just come and find out where to kite when they would be in WA.
I think some kiters (mostly newbies) go to crowded spots because they are like sheep, they follow the crowd
when they started they saw lots of kiters there, so they tought if there are a lot of people, it must be a good place to kite, so they kept coming there. and they never bothered testing and finding other good spots.
how many people always kite on the beach near the schools they took lessons from? first because they feel safer because they are near the school and after because they get to know the people kiting here and belong to a group
the solution is to spread a maximum of infos on every spots in WA. so kiters spread on different spots.
if you tell one of your travelling friend that kiting up north (or down south) is way better and everything they need to know, it may means you will have 3 less kiters on perth beaches the day after. and they tell their friends, and next year you will have 10 less kiters on metro beaches
perth beaches will always be more crowded you can't avoid the fact that there are about 1.7 million peoples living there. when you think of the percentage of people kiting in perth its so few. 1% of the population would be 17 000 local kiters. when you think how many people there is in perth who could become kiters, 20 or 30 kiters at scarbs is really nothing
when you think about 3 million passengers coming from overseas and 7.5million people arriving from other states arriving at perth airport annually, 20 or 30 kiters at scarbs is really nothing
the only thing that keep a good spot from being crowded is ease of access, I don't think lizard island is ever going to be crowded
hope this help
