I haven't seen anything flash up on the news yet. From what I've read on the two links that have been posted above there is something that is just not looking right. Can't say what it is just have this feeling that there is a lot more to this story to come out yet.

Old couple who love diving..very sad and condolences to family.
Bought a new shark shield 4 months ago after the first... 10 years old packed it in...had to borrow the money as i was broke...just wont dive with out one as i think we are a big hot spot for these massive predators.

What gets me
Speaking to Outwide of site yesterday about crocs. They use to be scared of boats up top end ( now they come to them). Whites never youse to see many now they come up to boats. Mmmm feeding them for tourism maybe. As far as people with Shepard shirts on why didn't they swim out there .This time of year until spring whites whites and whites . Last drum lines put out wrong time of year . Polical stunt. Def wrong time of year for water use . Don't let it stop you all together pick right time of year. Me personally I think it's time to thin them down. Don't dump them re search. People in boat today that is outright disrespectful .

Could have something to do
Could have something to do that most boats are hanging/dropping burley (blood and guts) over the side and they grow to learn the sound of boats = easy feed or the smell trail attracts them. For this reason i fish away from boats or popular boatie Spots just in case. I was 4km out on the yak on sunday at two rocks ( call me crazy and stupid if you like but its what makes me happy and relaxed ) when the mrs called to tell me. Ive been out there many times, but for the first time the threat felt real and i felt the need to tell her i loved her and i would be home at 3:30 on the dot. I feel that stunts like that from those sheaperd twits put lives like mine at risk, so if they have no respect of human lives why the fuck should i respect their lives. On another note its funny they dont use inflatables like they used to. Maybe they are scared of sharks.

Lol There's a thought, though you would probably need two divers to operate a five metre plus costume. You would also probably want it to be a male suit as could you imagine a 5+metre male great white sneaking up behind you trying to throw a fin over.

That is a bloody good question uncle
Unfortunatlky we may never know the answer to that question....why
Because the finiancial inept government is allowing the shark monetering bouys to drop in serviceability and is not going to upkeep them or replace them. Now this is not new news, but until I started to read all the stuff available on the great white shark and in particular a paper put out by our own Fisheries dept I never appreciated just how much info could be gleened from these shark watch buoys.
This should be number one reading material for those who take and interest in just what do we know about great whites and what we don't know about them.
http://www.fish.wa.gov.au/Documents/research_reports/frr273.pdf.
For a bankrupt blithering government to stop funding money for this kind of research, and then have the cheek to turn around when two people have lost their lives and make all sorts of noises about what they may done, just defies belief.
Do we know if the sharks responsible for the taking of these lives (would be a bloody good question to ask of the minister of fisheries) as I have said before the (shabby piece of toilet paper that has the temerity to call it's self a news paper "the West Australian")
When not making the news it reported that in the case of the Mandurah attack the shark was seen before the attack and reported, reported to whom. I don't know if the Mindarie shark was seen before the attack or known to be in the area. Before hand.
Why have I attacked the "West" so strongly, have a look at todays front page and page 5 these photos I find to have the aim of creating mass hysteria (hey but that will increase the sales right) who cares about accuracy.
I for one did not appreciate the amount of information that could be gained from the shark watch buoys and thus failed to appreciate what the lose of the shark watch buoys would be to studies ongoing into the great white migration patterns and behaviour.
I'm really angry and have not finished with this matter.

Having personally seen a
Having personally seen a large white , submarine cruise past my boat at the 5 fathom a few months back, I admit they are a magnificent creature but nevertheless I think that they need to be managed. (Culled)
Shark Smart web site states that a female Great White can give birth to between 2 to 17 pups per litter , if the last figure is correct thats huge and yes I know that not all survive but still.
Now a shark shield is not the 100% affective against a large White or Tiger shark - if they want to eat you they will and thats pretty much it. And thats of the research link of shark shield website link.
Its sad that you cannot enjoy a dive, swim, surf or biscuit tubing without always surveying the ocean now as the shark factor is always in the back of your mind. Oh and currently there 220 tagged whites.
My condolences to the victims families.

Water was very murkey
Water was very murkey yesterday out to 40m, in close it was like pea soup, plus whales starting to migrate north, plus an attack a week ago. In cyclone warning terms, it was red alert.
No disrespect at all, I was down at Mindarie when the boat came in, terrible scene.....but at what point do divers take responsibility and decide the conditions are just to risky?
I just could not imagine being in the water yesterday n those conditions without being terrified.

We hear the same myths all
We hear the same myths all the time. It was overcast, it was just before dark, the sea was like pea soup, certain months only and fish, whale migration. Science and statistics tell us this is all bullshit. Many of the victims have been taken in clear water and the middle of the day at any month of the year. If there is one in the water near you and its hungry or wants to investigate your screwed. The point here is there does seem to be a lot in the water for an endangered species. Yesterday, one at Busso, one at Dawsville and the one at Mindarie. If only we saw so many appearances of other endangered species.

Then What !
They have been doing it in South Africa for years and there is no evdence to suggest more attacks by going in a cage ,teasing them with bait . In my opinion , by opening up the area to this sort of tourism , could only benefit scientists /researchers with id , numbers of sharks that frequent certain areas etc . Its done in South Aus too , so whats the problem ? I for one would jump in a cage to watch them , be friggin awesome !

Wrong place wrong time
Bad vis was a contributing factor but I think that shark was hungry and came across them and if it had been clear probably the same result. Interesting that it brushed past the bloke to get the woman.. I am a keen diver and wont dive in bad vis anymore for the shark and enjoyment factor. Terrible thing for all involved in these attacks. Time to let the commercials fish for sharks in the metro area.. There is a duty of care here. Cant have these big predators stalking the coast line. Just need to thin their numbers a bit to balance things out

Crow eaters and sharks
I have just read this article and it makes for some very good reading. Various people have made observations about the number of sightings of great white sharks and how prevalent they seem to be.
The CSIRO have done a study to see just how far know tagged great whites travel. They travel quite long ways doing what may you ask, taking in the scenery no, looking for a place to spend the next holiday time at no.
Chasing food.
Guess what, WA at the moment is enjoying one of the best salmon seasons it has had for a long time, salmon are food for great whites. Any way have a read of this article and when you have a look at the distances and just where these sharks travel from and to I'm sure it will get your attention.
The article leaves me with a question, they have feeding great whites from cages in S.A. now seeing as the same sharks travel from SA to the west coast do these sharks learn that boats and people in the water equal feeding time.

Extremely interesting
Extremely interesting article. I have pulled a few points from it:
-Australian scientists know white sharks follow food
-They know they can spend days, weeks, sometimes months in one area
-Predicting exactly when or how long they will stay – or what danger they pose to humans – is still unknown.
-Bruce estimates a shark travels between three to five kilometres per hour and is capable of covering around 70 to 125km per day, 500 to 875km per week and 2200 to 3150km per month.
Reading the report makes me think that taking one or two sharks out of the system will not make a big difference as they migrate so far, so quickly. I do support baiting for them to catch sharks that may be hanging around posing a threat.
The clear con to a bumper salmon and snapper season is clear.
Time to re-open the fishery and add a boost to the local economy.

I see you like to play around
I see you like to play around with statistics. Why would you use Perth population? How many of the migrants/refugees in the last 30 years are out there surfing and diving or can even swim?
For arguements sake and considering a key timeline being the conservation status of the Great White which is the arguement that a lot of us have for the increase in attacks perhaps you can use your source data to do a more comparitive analysis.
2000-2016 compared to 1983-1999.

I had a play around with some bio statistically irrelevant figure too using census population data and population projection data but at least I am comparing your apples to some kind of apples…
1991-1996 average population was 1,235,000 with 2 fatal attacks (abalone and a pearl diver).
2011-2016 average population is 1,930,500 with 9 fatal attacks so far (all recreation activities )
1991-1996 = 1 attack per 617,500
2011-2016 = 1 attack per 214,500

It was WA population vs WA
It was WA population vs WA attacks...seemed like a logical choice, No?
Are you stating that only WA born and bred people should be included in the stats?
My point was only that statistically, It was much worse earlier in the century. I have no idea why.
All I know is that when I was a kid, very few people surfed/dived at the places where people have been attacked. Now, its like Hay st.

Now I'm saying that when you
Now I'm saying that when you are conducting a biostatistical analysis you need to base your figures on exposure and not raw numbers i.e. does the exposure to sharks increase at the same rate as the population in the last 30 years? Going purely on raw numbers however, there's not too many fatal attacks between the 1960's and 2000's when people had the means to catch great white and it was an activity undertaken. It picks up dramatically once they become protected.
I could only wish I was around when I didn't have to paddle into a packed lineup at Lefties, Gearies or Boneyards.

"does the exposure to sharks
"does the exposure to sharks increase at the same rate as the population in the last 30 years?"
Considering that most of the people I have dived, fished and surfed with over the last 20 years were all migrants to WA (from other states and overseas), I would say yes, it likely does.

How many attacks in the years between say 1960 and 2000? That's a fair chuck of the time period that people used to actively target sharks.

When there was no snapper ban
Never ever seen white pointer in cockburn or warnbro sound ever. And I would fish very regular. 4 to 5 years after ban was on they started appearing?? Goes to show ban has worked snapper numbers increased dramatically . Great place to bring big and baby white pointers in .easy supply ,of easy prey for them. Not saying lift ban just observation .Proof in this would be how many whites tagged in sound or sitings prior to bans. And do other way. After bans. I know which one wins hands down . Especially sightings. Def coming in for food. Opposite to what greenies are saying rapeing stocks .

yep agree john, same down the coast 15 yrs or so ago no seals rare whale sightings add that to stricter fish quota etc. Stands to reason that protection and more food equals an increase in population. Greenies must have their heads in the sand if they don't realize this, but it's hard for them to understand when they don't leave the safety of their computer chair

The productivity of any
The productivity of any fishery relies on a supply of food. We have protected there main supplies of food which have boomed in numbers so why wouldnt they boom in numbers as well. I live in exmouth but it seems something has happened with proffesional salmon fishery with the massive quantities that are now making it to the metro area and beyond. Ive actually witnessed down south one year a white feeding on a salmon school, it looked as though it had no trouble catching them. With the amount of salmon around there could be hundreds of them in close at the moment along the coast. As long as we dont see them in exmouth ill be happy.

Just my 2c worth, Nature is
Just my 2c worth,
Nature is great, back before white man came to Australia eco system was in balance, ratio fish sharks etc.
Along come the fisherman and starts taking sharks and fish and generally stuffing up the balance of the eco system.
Sharks are at the top, Apex. Great whites get protection as do other sharks greater than 700mm inter dorsal fin measurement.
So now the sharks ( apex ) have had protection for a long time to allow their numbers to increase, which they have.
But the same has not been done with the fish stocks ( limited controls but not total protection of the large breeders ), hence the eco system is out of balance.
We control fish numbers via a quota system for the pro fishermen and bag limits for the rec's, yet there is no control in place for the larger sharks.
If you are going to have limits on the fish stocks then you must have limits on the larger sharks or the ratio will be out.
If we are to protect the apex sharks then to keep the balance in the eco system we must stop fishing.
So who is ready to hang up their fishing gear?
If the greens had their way then nothing would be taken from the oceans.... they are getting there slowly.
We need to fish for the future, we need to have quotas and bag limits to preserve stocks, but IMO you cannot let the numbers of the sharks keep going up the way it has without having an impact on the fish stocks and having a increase in interaction with humans.

good well thought out
good well thought out argument.
I agree there are too many LOCAL (non nomadic) sharks and that we need to make use of this resource. IE commercial sharking. (don't know much about how this would work as Hezzy's stance against netting makes good sense) and that the non migratory shark population is out of balance.
my main thought though is that I believe we have no idea as to weather there are more GWs in the worlds oceans or there are just more GW in the south west aust area.
Someone further up said "more food more reproduction" which of course makes sense at first glance ...but do we believe the world's oceans have more food in them than 20 years ago.
Knowing that individual GW can travel thousands of kms all over the worlds oceans who's to know wether the GW is thriving world wide or being starved out of the majority of the obviously depleted world's oceans and congregating in the areas of well managed fisheries.
Looks like the fisheries have managed our local waters well and life is teaming locally. (not so with the worlds tuna stocks etc.)
Why are these 3m plus sharks coming in to eat pinkies and salmon when I thought it was a pretty well known fact that the bigger sharks switched to big mammals seals whales etc ? Seems strange
I would love to know if other countries are seeing a huge increase of sighting and attacks or are we standing in the middle of rottnest's oval saying "shit these quokkas are out of control"

The thing that get me is when
The thing that get me is when the GW were placed on the endangered list and given protection, science said there were "X" number of GW sharks left in the world, but ask them now how many there are and they cant answer, funny that hey

yeah think the numbers
yeah think the numbers estimated when they were first put on the endangered list was estimated from fishing catch so to get a good estimate now we either have to bite the bullet and spend money on research .... or fish an "endangered" species (which is not a good look for aust..... haha just put "research" on the fishing boats....sorted)
my thoughts all along is to get some meaningful data on numbers and scientific thoughts on why the increase in this area then make an informed decision either way.

Just did some match based on
Just did some match based on some quick research I have done from credible sources.
One female, can produce between 2-17 pups. Average is 9.5 pups per cycle.
Gestation period of 12-18 months, and breed approx. every three years.
One shark, breeding every three years since 1999, producing ~9.5 pups has now produced 53.2 pups.
It was estimated that when they were protected there were ~10000 sharks, assuming that ~50% are females and half again are breeding age (2500), that works out to ~133,000 new sharks since.
Now my maths may be on the piss but that is a lot of sharks that have been born since 1999, born at ~1.5m. Based on a growth rate of ~10cm per year, the sharks born when they became protected are ~3m+. The big sharks around are old sharks.
Based on the maths, a female GW shark is ~4.8m long at breeding maturity, males are ~2.5m long
In my opinion, time to open commercial shark fishing and target male sharks over 3m.

good number crunching , did you add in to the babys of the first breeders reaching maturity and their babys etc etc to get your total ?
second thing , why would opening the commercial shark fishery in the metro reduce attacks there when it hasn't anywhere else on the coast ?that they can fish now ??

"The litter size of the great
"The litter size of the great white ranges from two to 10 pups, although litters of up to 17 pups have been documented [sources: MarineBio, McGhee]. At birth, great white shark pups measure 5 feet (1.5 meters) and weigh about 77 pounds (35 kilograms)."
I worked out the average of (lowest + highest) / 2

Many sharks out of the 10000
Many sharks out of the 10000 were breeding females? There are many many variables. Based on a little of 2 pups, it works out to 28,000 more sharks. Impossible to know exact as the Sharks try to eat the interviewers

Yeah absoloutely understand.
Yeah absoloutely understand. By no means do I think that every born shark makes it to maturity though potentially the population could have swollen significantly.
It has actually changed my mind on a cull, rather open the fishery and whilst commercially fishing, do some agressive research.

Behaviour
I reckon it is more a case of change in behaviour rather than a change in numbers and cage diving does not help.

With many of the tagged
With many of the tagged sharks moving from the Neptunes in SA to Perth/WA and back you'd have to ask the question

You don't want the pro
You don't want the pro fishos they wouldn't have a net that could stop a large GW. You would just be saying goodbye to all the good demersal work done over the last few years. Big hooks equals big fish.

The argument on commercial
The argument on commercial shark fishing has no foundation what so ever unless Im mistaken. The pros will only take certain species as they have stated and will not be interested in Bull sharks, Whites, Tigers ( the main killers) .The high mercury levels render them useless. So all that would be acheived by allowing commercial Shark fishing is decreasing the small shark species available to recreational anglers like Gummy shark, small Whalers etc, which are no threat to anyone at all. The only way a commercial operation would ever be viable would be a Bounty set by the government per White Killed and full usuage of the animal in some way, eg Shark fins , Leather and the meat being processed for food or pet food or some other use.

What would happen to the by-catch
Like dhuies, snapper, baldies etc would they be returned in good condition. I don't think so.
