Well I am completly blase' about kiting in the ocean. I don't give it a second thought.

When people ask me " aren't you afraid of being eaten by a shark"
I say "I have more chance of being killed by a vending machine"




Last time I bought a coke the vending machine didn't bite my legs off. I was formerly in the no killing camp... But I work in safety risk management, and if there is an identifiable risk, i.e an increasing number of attacks over the years and as Darren mentioned a measured increase in sightings of a species known to be human killers in a given area, I am pro culling.

IIRC Sharks are one of the only things left that are just barely controlling the population explosion of Humboldt Squid along the west coast of the US.

These squid are intelligent, hunt in packs, and have the potential to take down prey of any size.

Pussies! How often do you spend in actually the water each 'kiteboarding' session.
I have never heard so much shark hating BS than here in WA!

Totally sad news about that young man.

But seriously suggesting we go and cull great white sharks is just retarded

Dude after u watch this film that Rob Stewart made


U will totaly think different about skarks, and we also need them to live but the ways things are going with shark finning and long lining it is estimated that sharks will be gone im my life time~!!

Anyway the thing is that most people dont know is that sharks kill 5 people a year, elephants kill more, bending machines, car crashes, smoking, cancer, all kill more people a year then sharks!! so one life by a shark doesnt mean we have to kill an species of shark that is already endangered.

Working in Risk Management you should also understand the idea that you work at the simplest remedies before attempting the more complex ones. Undertaking shark culls is expensive and time consuming and likely to make little difference. By your rationale the best solution would be for none of us to go in the water at all. That would be the simplest option and most likely to make difference. But would anyone here be willing to implement or participate in this risk mitigation strategy?

Getting worked up about shark attacks has to be about as futile as getting angry about a natural disaster occurring. It's amazing that our egos have got so immense that we have this crazy idea we can control everything.

Yeah... My head tells me to agree... My heart is still thumping from getting knocked off my board yesterday by a 2m shark at my local. My hair was dry after half hours kiting and hadn't body dragged once or been off my board. Scared the sh!t out of me... And I don't like being reminded that I can't control everything when I spend all my days trying to stop people getting hurt with all the means I have at my disposal! But I see your point lostinlondon.

Edited to say: I had an employee and good friend killed on his way home from work almost a year ago under my watch. Since then I've implemented a campaign of anti-fatigue, driver safety training "arrive alive", relaxation training to help people get good rest to ready them for their 12 hour shifts... There is an independent councelling program so people can sort their **** out if its something outside of work affecting their ability to work... And I am available 24/7 for their calls should they think in any way there is a risk or hazard that could be life threatening so I can go out and find a way to mitigate it. I fix thIngs! But this might just have to be one I cannot fix.

Do we really need them? Yes, we do.

We as a species need biodiversity to survive. Biologically diverse ecosystems are resilient and flexible. Monocultures - such as wheat fields, salmon farms, and chicken batteries are inherently unstable, vulnerable to epidemics, and require massive inputs of energy (fossil fuels) and other chemicals (antibiotics, pesticides etc) to keep them running. Sustainable harvesting is what we need, or there will be long-term consequences far harsher than our average annual shark-attack toll.

Apex predators are crucial to the health of an ecosystem, and the ocean, like the soil and the atmosphere, needs to be healthy if humans are to survive.

The range of species and food chains/webs existing today took many millions of years to evolve. We need them to survive because we can't replicate biodiversity.

As many of others have said, there are many of other causes of death we could attend to, and though they may not be as spectacular on an individual case basis, the statistics of people dying from lifestyle-related degenerative diseases are truly spectacular.

I'm not saying I'd be happy to be killed by a shark, but that I'd rather take that miniscule risk than risk our species' survival by deluding ourselves into thinking we only need species that have obvious and immediate benefits and that we can do without the rest. Cybernetics 101: part of a complex interactive system can never control the functioning of the whole system. We must learn to participate, not aspire to control.

Everyone has their opinions and are entitled to them

An unfortunate accident like this in an environment we all love to enjoy is a good time to take stock of how we feel about the ocean that we share with its natural inhabitants.

Condolences to the family and friends.

kill the sharks, kill the great barrier reef, kill australian economy, kill being able to afford new kites each year.

sharks are scavengars that feed on the sick and week. they keep disease down and increase the strength of the genetic pool in fish stocks. do you really want massive disease outbreak killing the australian fishing industry as well?

and do you honestly think a shark is quick enough to catch a kiter or be willing to breach to bite you?

how about before you jump into an unquestionable opinion you do just a little bit of research.

if sharks really wanted to "feed on humans" we would be long gone, no-one would dare enter the water.

good luck keeping a species that migrates such long distances away from certain spots.

and what kind of idiot decided you had to be a tree hugger to be able to think before you act??? how bout we introduce cane toads to kill cane beetles, good idea Mr idiot, those beetles kill one person every year, toads will solve everything.

a govt funded tagging and tracking system would surely be money well spent? keep an eye on their migration patterns? i see the irwins tag crocs at a cost of $7K per tag, the govt wastes $30K on PS3's for asylum seekers i'm sure they could spare a couple bucks to tag a few man eaters?
but no killing or culling. and east coasters calling west coasters red-necks is the pot calling the kettle black. -alot of us are from the east.

This was done a few years back off SA and indeed may still be active there used to be a link to it on I think another weather based site can't remeber which but one thing I can remeber is how consistent the travel patterns were, no doubt they are territorial. I guess that's one of the better arguements for culling "problem" animals.

A few years back there were a bunch of incidents locally within a couple of months in the same area, anecdotally a similar sized fish had visited the same area in the years before and has been sited since. Hardly science but....

We live and run a Kite and Sup school in Pt Lincoln and i can assure you it's hard work trying to get people in the water around here.One of my best mates was taken here by a great white, my neighbour and my girlfriends schoolmate but hey we all still hit the water everyday.Your first reaction is kill the shark but after the angers has gone you start to think more. Do NOT agree with the chumming of GW to cage dive... do not agree with huge shark cage diving signage being put up around town and do not agree to killing the Great creature of our sea.And as we all know the statistics are low . Tagging and tracking def the answer but at what cost ?? And i agree to this our.. Dodgey Gov should save money elsewhere and consider the suffering of families that do lose a member of their family to a great white. It's a very strange death especially if the body is never recovered for the grieving process.
All respect goes out to anyone hitting the water and living the life you love to live and for anyone ever that's involved in a shark attack death !!!
Full respect to this guys family.

So the stats say that you have a 1 in 3,748067 chance of being killed by a shark.
Is that is stat counting ALL people... of which many don't even live near an ocean?

Stats can be made to say anything.

We are top of the food chain. Sure, we should be humane and preserve biodiversity but if something becomes a problem them we have need to deal with it.

Very balanced and informative post, intelligent as always. But, if that was your son, would you be so 'removed' - I think not. There is also a biological and evolutionary drive to protect ones own. Agreed on all points you made, but what if?

We have the brains and tech to be custodians of the land and sea.

IF we decided to wipe out a species of animal then we could do it. I'd like to see sharks wipe out all humans.

Just by naturals prowess who should rule the earth? Lions, gorillas, elephants? They can all kill a human easily but they are not in charge are they? Like it or not, we are.

^^^^^Hunting "the" shark is not as easy either. Hard to ask a shark did you do it or was it one of your mates. So what do we do with these "ocean terrorists", a kill or capture policy or just kill?

Nature has provided many "monsters", polar/grizzly bears, lions, tigers, and hippoes. They are all killing humans more than ever as they encroach on our environment and eat/destroy our food sources (oops I think I got that the wrong way around). I'd hate to tell my 4 year old about all these apex predators and how they are almost extinct,"but you can still see them in a Zoo".

The greatest "monsters" are us.

I don't get the kill the rogue shark theory. If a shark tastes something it doesn't like
(they say great whites can't survive on our bony bodies) then surely if there smart they won't be back for more. Has a great white ever attacked more than one person
or do they learn after giving it a try

Condolences to the families of this boy lost and everyone else lost to the ocean.

I know the risks of entering the ocean, and in my view, i'd much rather die doing something i love, than say killed in a car accident on the way to a mundane job, or poisoning myself with cigs.

If you don't like sharks, then don't go in the water, and as a friend says "if sharks stay out of the pub, i'll stay out of the water"

Most ppl that surf, kite, dive, fish, swim or whatever know the risks.

Just saying, sharks should be protected, its not them entering our world, its us going into theirs.

I didn't say we should do it but history has shown that we could. Sometimes we even manage it by accident.

Let's say we had the tech to deter all sharks from popular beaches... should we do it? Or do they have the same rights to enjoy the beaches as humans? I would keep them away.

Do these Shark Shields work? I'm led to believe the evidence is a bit sketchy, but if they were proven to work, would it really cost too much to have stronger, submarine versions of these placed 100-200m or so off some of the more popular beaches to try and deter the sharkies from venturing into the surf/ swim zones?

Sounds like fairly simple technology to me (the non-expert in marine acoustics)

First, condolences to family and friends involved, RIP Kyle

Every time we dip our toes in the big blue ocean, we enter an amazing marine world and with that, mostly a small degree of risk. Others mentioned more risk in our human world and I couldn't agree more, there is considerably higher risk, ie cars, one punch knock outs, road rage, vending machines, your poison/s etc etc

We all love the ocean sports we do, and I for one are prepared to integrate with the marine realm for this interaction.

The Bunker Bay area has somewhat higher risk than other areas due to a nearby seal colony (see attached) and a prime source of food supply for the Carcharodon carcharias - Great White Shark. We all revisit our favourite food supply be at home, restaurant or pizza bar. We all know we look similar to a playful seal when we don the black rubber and start thrashing around after the excitement of an awesome wave.

Not being alarmist, but anecdotal evidence suggests this colony is expanding and also establishing further south around Cowaramup Bay.

I dive regularly on the south coast of WA, and have yet to see such a beautiful beast but we take additional precautions and use the shark shield devices.

I for one don't want to see any culling and am happy to wear the risk, which is probably significantly less than your human life.

I kinda agree with coreyb,

Since joining our spearfishing club 4 years ago there were only 3 or 4 of the older guys who had ever seen a GWS and I was told it was such a rarity that it was an amazing gift to actually see one.

Nowadays, just 4 years later, they are being spotted fairly regularly by club members and it is now not such a rarity. Knocking off a few of the ones who stray close to the coast wouldn't hurt.

Since their protection, their numbers have swelled quite dramatically. The problem with protecting a top of the food chain predator is that we are wiping out their normal food source for human consumption. This messes up the eco balance.

Just wiping out a species isn't the answer, careful management of the entire marine ecosystem is the key. Seeing as the government couldn
t organize a root in a brothel with a skin full of piss and a $50 note in their hand, what hope have we got of success in this area?

Til then, we lose a human or two every year. Survival tip! Don't ride a shark biscuit.

Condolences to the family and friends of the boy taken.

DM




I am divided on the issue, whenever you get a salty that comes to close to people they get "relocated", not sure how you go about doing that with a GW, when a lion kills a human they get terminated, if a dog malls a kid it gets the needle........I personally would feel better knowing that a problem GW was "out of the way"

The problem faced is that they roam anywhere in the range of 50 000KM from Augusta to Cape of Good Hope.....and what does not help is the bloody idiots dragging surfboards and rubber seals behind the cage dive boats to get them to breach so the tourists on the boat can take photos........

Perhaps they need to install high tech fish finder type devices along the coast that alert the life guard services that a large object is in the area, I have read a number of article about a tagging program but they are not long term as devices fall out and is not a practical exercise but more a research tool for a case study.

I believe August to Sep is the time when they are around the Perth SW and metro areas heading up north!

Perhaps we need to have a GW barbeque every now and then to keep the pests away.....

Deepest condolences to all his friends and family.
