Ah, ignorance strikes again.
'Our sharks are out of control'?
Pah-lease.

Oh and comparing croc ecology to sharks? Doesn't work that way.

That's your reply? Ha!
Yep, ignorance = bliss

Suba the more you get worked up about the animal you love, the less credible your opinions become. There are only a few things I have understood about you.
You love the ocean and all the creatures in it especially the GWS.
You have spent many hours researching the ocean and creatures in it.
You can't stand any person who has an opinion different to yours and feel you need to abuse their view's and intelligence.

was this in WA Zuke? been fishing all my life and have caught maybe three, thought they were very rare in these waters, hence the name. My mates that spear fish say that a lot of fish seem pretty easy, namely coral trout and dhuies. They say these two seem to turn sideways to look at you! fatal behaviour when being hunted.. I would say your theory on the PJ's seems valid, I wonder if they are tasty as this seems to add to a species vulnerability either tasty or scary and you're in trouble it seems!

Bakesy, I am in believe what Zuke has written is correct. The floors of the ocean in the 50's and 60's were plentiful of Port Jackson's and made easy pickings for the tough fisho. This was the same as the Grey Nurse. My old man has told me he eat a few when he was a kid, but didn't fancy the taste. The one in my picture is a big catch. It would be the biggest we have caught. The area we fish we would catch 1 or 2 a session, some times 3. I don't hate sharks, I just think it is time to cull the not so friendly ones.

they tag GWS and monitor them, they are still pretty unsure of their behaviours but are getting there. problem is this is in the states but they are hopeful that the research will benefit other countries,

They do the exact same thing here

have you seen the show? they've got some pretty high tech gear, not sure we can lift them out of the water for 15 minutes, take blood, semen samples and install the state of the art software these boys do. Plus they have done this to around 30 sharks in the last couple of seasons. I know the yanks like to brag a bit but in this case they're right, done nowhere else in the world like this. the head honcho is a Dr Domeyer (think that's the right spelling) and he is the man!! Millions spent.

Yer bakesy, fish Mandurah and out behind Rotto. The PJ's we get are more down towards Bunno. I was a deckhand from 89 to 95 on wet liners and cray boats, had my first kid in 96 so had to get a steady job for the sake of the Mrs. I still go out on a cray boat on day's off for fun and catch up but no longer can wet line on them. On our little boat we have been getting whiskeries a lot but haven't seen a hammer for years. 15 years ago it would have been the most common our boat would have seen out from Mandurah. Last year we had three Bronzies mess with us all day while diving, but never got nasty. Over the past 10 years mates off boats are telling of more and more accounts of GWS in areas not seen before. Not so comforting if you gotta dive for a pot stuck under a reef. Even been told of a pot that was being chomped while being pulled. My Grandad was a fisho and would tell us of the Big Whites down South around Denmark and Albany, I never thought it would be around our shore's. The ocean play's a huge part in our life through work and play, so to me the ocean is just as much my home as it is to the shark. From what I have learnt, these sharks aren't stupid. They can work in teams and do have memory. As they feel less threatened in the inshore waters, they will come closer and closer in.

The one at Tims that is there year after year was back again on Saturday, think it may have got to Avalon Sunday morning. In saying that I had one under me at Gearies last year, just a small one. I walked on water and carried my board out. When I got to the car park my son asked if I had seen the fin just behind me, he took a look at my face and new the answer. Or was it the smell.

Just one question I have is - why have the GW's in particular been drawn to WA in such larger numbers ?, I mean what has changed their normal foodie targets (seals , penguins , whales) to human? is there or has there been different migration of their normal targets? I have seen docos indicating that water temps are rising / changing + we know there are more humans in the water nowadays.
Please know that I'm not for/against culling - personally I'd be sh!tting jockette and wouldn't be even thinking of aiming a harpoon (bout the only surefire method given size of GW's) I'd be a flying Dog aiming only for the shore or boat fellas.

Cheers Prawny - the whales migrate up past Exmouth every year so probably explains going up that far...... looks like we've got more Whiteys than usual on the lurk this year & more rain too , water has been dirty etc.
Thing with Whiteys is that set of fangs - and that the jaw pops right out of that snout , giant guillotine basically , monstrous bite pressure to boot.

Excellent link Prawn

With all the attacks in populated areas of late, its probably time the government started funding more research projects similar to the "shark men" in Perth waters.

I noticed that most of the sharks tagged were in remote SA. Would it not be better to tag sharks in a populated place to see if they are territorial or "local"?

Do we kill off all the roos as well? -

WA woman walking dogs mauled by a kangaroo

A woman has suffered cuts to her neck, ear and back after a terrifying attack by a kangaroo while she was walking her dogs through bushland in WA's southwest.

Janet Karson of Deanmill near Manjimup, needed more than 20 stitches to her ears after she took on the kangaroo which was attacking her dog.

"I went off the main track and suddenly this big kangaroo jumped out from nowhere and one of my dogs chased after it," she told The West Australian newspaper.

Ms Karson ran after her blue heeler and found it being bear-hugged by the kangaroo.

"I used a stick to lever its claws off my dog and then it reared up in front of me - it was huge," she said.

"All I can remember is its claws going to work on me and the smell of my own blood when my head fell onto its chest."

Ms Karson said after the attack the kangaroo hopped away.

She said it was a miracle that she survived the violence but did not blame the kangaroo.

a number of very valid points being made here, I wonder how we feel about the department that is ultimately responsible for this issue. I have been subjected to the various bans, limit changes and protection zones for the demersal and other species that I target and fully support the ways things have been done over the last 30 years. I personally feel that a massive budget increase is needed in this area and that a percentage of that should go to GWS monitoring and research. The shark patrol is awesome but how good would it be to have a tab on this site that tells us where the GWS are (at least the tagged ones) the tech seen on Shark Men is not perfect but like all tech is going forward in leaps and bounds. Fisheries research needs more personnel and more funds, think about the budget for road safety and council rangers and in a water loving state such as ours it is a disgrace that we don't have something like Shark Men going on. It's pretty obvious that GWS attacks are on the rise so when will we see more being done?

basically these GW's are an animal(fish whatever) following their instincts,that's all it's nothing personal against humans imo , I'm a human (pup whatever) and my instinct is to know more about something , in this case GW's .... I like to get in the water too but these things are around Perth / WA in numbers & SIZE.
