Have finally realized that not only do they kill sharks...they kill everything else as well with shark nets...and have done so for years....

Best sort you own government out before complaining xbout WAs!
The system works, providing a moderate amount of protection for a low cost in by-catch.
Actually reports showed when they were first installed the nets, total of by catch has dropped of considerably. They put that down to the fact that the nets just killed of the entire eco system

Who is "they" in this instance. I think you are making it up.
Sharks < People.
Thats the funny part. It was in the report completed by Bond Uni for the WA state government last year. The one that said it drums and nets would not work for WA
I stand corrected:
www.fish.wa.gov.au/Documents/occasional_publications/fop108.pdf
"A key environmental issue with the use of mesh nets for shark control in both Queensland and NSW, is
that catch rates of by-catch species were exceptionally high in the years just after placement of the nets
in the water and then declined to relatively constant levels (Green et al., 2009). The most likely
explanation for this is that the mesh nets ???fished down??? the local populations of a number of by-catch
species. This is not surprising since the aim of shark nets is to fish down local fauna ??? specifically larger
individuals of key species. It follows that local by-catch species are also likely to be fished down. In the
case of dugong in Queensland and grey nurse sharks in NSW, the declines in the local populations are
important in the context of the population as a whole. Similarly, in Western Australia the implementation
of shark nets is likely to result in very high catch rates of by-catch during the initial few years."
The report focuses heavily on nets, which the author seems to use interchangeably with shark control as a whole. Nets dominate the conclusions. They do grab a lot of other animals, though only 2-3 dolphins per year in NSW.
Presumably why WA is going to use lines and hooks....
Yup nothing here, it's all dead.
The moment a shark or anything other than a human or jellyfish appears it's on the news, and the whole place heads down to the water for a day of wildlife.
I remember just 12 years ago you could see dolphins, light brown penguins, rays and the odd shark (usually a wobi) on an average surf session.
Now? Nada, zip...
Do you also want that?

From memory it also talked about WA being mostly long stretches of beaches , as the east has more bay systems. SO it was considered by catch for both drums and nets would be considerably higher as it would directly impact more north south fish traffic..Something along those lines
Money well spent by our state government. Ask the experts, but then do what is politically better seems to be the answer for Culling Barnett..
Sharks need to eat, and with decreasing fish stocks they are eating humans. The Australian government had a meeting and decided to protect the Eastern states where the more important people of society live, then, had the choice of Tassy or WA to be left open to feed the sharks. Obviously the choice was simple and all voted for WA as the most dispensable state as its the place most full of Euro's and red neck desert dwellers. C'mon people,, a few killed in a year and you all get SUCKED in to the media hype and start crying to the council to protect you??? What next,,,you cant build a sandcastle on the main beaches in Perth in case someone trips over it??????....Oh,,wait,,, they have already done that. Why is it that the families of the real watermen that have been taken by a shark are all saying "No, dont kill the sharks" ??? Is it just the once a month water goers that are having a whine and getting sucked into the media hype?? I have yet to see any of the REAL watermen/pro surfers etc that spend all day everyday in the ocean have a cry about the odd shark in the water. And those guys are laying on surf boards paddling slow, while most of us are moving fast on top of the water. I guess its a bit like soccer players crying if someone bumps their shin, while the rugby players laugh at them.
