Right, now you've done it (not you in particular YB) another never ending bloody shark thread. Don't blame me you've brought this on yourselves.
the queensland nets dont normally account for the bigger sharks. The big ones are targeted by the use of baited drum lines.
Tigersharks are scavengers and opportunistic feeders. The eat anything but don't expel lots of energy hunting stuff down.
Great whites are hunters, used to preying on and attacking agile fast swimming mammals of similar size to humans, that look remarkably like seals whilst perched on a boogie board.
Overfishing doesn't affect great whites IMHO as they prefer high fat mammals like seals and whales. There are more of these now than ever due to protection so I would say that the increase in white issues would be more due to increasing whale and seal stocks than overfishing. Remember that whales were hunted pretty hard (humpbacks near extinction) for well over 100 years.
As for the theories of sharks becoming familiar with man due to cage diving, they document and research the sharks that they see. Possibly they would know if one of the sharks that they had seen cage diving off SA was involved in a fatality in perth if it was caught? Sharks there might not go to WA. You would think the researchers would be onto it if they did.
Same old boring argument. "The ski is falling" Way to go chicken Little's
Stay out of the water for f---sake..Leave it for the people who can see/access the real dangers in life, oh and our kids
I don't really think the sharks are as smart some state they are. They actually have very small brains. There movements are far to random and most of there underwater patterns are navigated by magnetic fields and underwater highways not by memory.
Where the cage diving is located the sharks have been visiting the same sites for hundreds of years.
All the cage divers do is Bearly them up to the surface.
If you go to these spots and just anchor up you would be lucky to see one come to the boat or even surface.
I really doubt this industry entices sharks to feed on humans more along the lines it may feed them up on fresh tuna which in turn will make them more active for breeding cycles. These sharks do eat fish and as someone stated there main diet are seals well that's not exactly true it's more than likely optuinistic for sharks to grab a seal rather than a snapper or tuna.
Like I said how many attacks were there in the 1700s when water sports where non existent? There are less sharks, less food and more humans using the water now ....this is the only reason we see more attacks ...... And what has the Batavia got to do with this thread I have to wonder?
I agree with Razzonater and can relate to what he says. In Adelaide River, Topend, the jumping crocodile cruises are very popular. They started about mid 80's from memory. I used to love fishing in small dinghies in systems like this, but eventually stopped due to this hazard.
Quick question: Why is Perth lite up like a christmas tree on the link below ?. Is it because this is where the sharks are, or is it because only WA people are reporting sharks ?http://www.sharkalarm.com.au/
I guess even the sharks know we have the best beaches, lifestyle and west aussies would surely taste better 
And yet people keep swimming / Surfing etc, at the same places every day that are known shark areas, and then complain when they or someone they know gets bitten or killed. And they say humans are smart? If they were smart they would not swim there again.
Would you put your hand in a blender knowing that it could take your fingers off?
One species right to life versus another's right to recreation . Seems a little unbalanced certainly from the sharks percpective .
Such a majestic fish! who would believe that they are not such a cute and gracious animal as depicted in this video.
Maybe they should all be called Shamu! or Sea Labradors! its all about the marketing!
If the lovely girl diving with them, however unlikely was killed accidentally by the fish would she be considered suicidal by society or just unlucky?
I did the shark cage dive out of port lincoln this year and there was only 1 out of the 8 sharks we saw with a tag. With 40 tourists paying for the boat (and dec getting a decent slice) to see them you would also think they could be doing a lot more to study them. The second we dropped anchor one turned up even before burley was put in the water but then the sharks up here turn up behind the trawlers every night too.
What we should do is wipe out every White pointer....then we wouldn't be having this thread. Or we could just stay out of the water like these guys below.
Excellent turtle hunter clearly an indication that 7 out of 8 sharks that do come to the cage diving are not researched or tracked and also have learnt habits such as boat motor off, feeding time....
It's unbelievable that these learned habits are encouraged.
Do not think this is an attack on you as a person.
To dive with a great white is no doubt on many people's bucket list.
And unfortunately this is completely unregulated and encouraged.
There are two distinct breeding grounds for great whites in Australia with scientific proof of genetic difference in DNA, meaning that these sharks are taking learned habits with them.
One is in south oz in close proximity to port Lincoln and the other is in wa I will not post specifics as this will only encourage 'punters' to mess with there already increasingly learned habits....
Take it you had a bad day
