Please don’t remove the shark nets

I am intrigued by the shark nets saga.
Queensland is used as a reference for baited hooks. Queensland and Western Australia have the highest incidence of shark attacks in the world.
The big shark will be attracted to the smell of the bait from far but by the time they arrive the little fishies will have eaten the bait. A very viable alternative for the shark is to eat a human and he won’t be inconvenienced by having this big hook in his mouth. I was given to understand that the whole idea was to repel sharks. How many shark attacks have there ever been in areas with shark nets?
Please don’t remove the nets. One attack in this area will have a devastating effect on the whole community.
If the greenies were really concerned they would visit the many river mouths that are infested with poison from the factories up stream.
One of those many factories does more harm and probably kills more sea life than all the nets put together, and surely kill more humans. The rocks off Blythedale beach are barren, no mussels, no oysters, only rock.
Greenies, in many countries factories pump water from downstream of the factory. Our factories claim the water is clean downstream so why don’t they re-use their clean water?
