Me personally, it would be seriously hard to get in those waters if I knew there had already been 4 other shark attacks. After all, you are entering their environment, and killing is what they do. Like a couple already said, you don't want bitten or ate, stay out of the ocean! The nets have worked for different areas. Maybe the Australian gov should go that route. Even if you kill the shark that is thought to be the killer, there are plenty others hungry and lurking too.

I watched part of shark wranglers on Discovery channel the other night, and they said the great white population has tripled in the last 20yrs. That's the ones they "know" are there. They said who knows for sure how many are really out there. And by the way, those dudes are nuts!
