I used to be a surf life saver on a very popular Northern Beaches beach called Dee Why. On a few occasions I spotted sharks out in the surf. We just had to inform the swimmers and keep an eye on which way they would swim, and try to guide them out to sea again with the IRB's. I also swam over a few hammer head sharks not knowing they were there, we only found out after we returned to shore, and the person who spotted them told us, mind you he was sitting safely on a large rescue board and decided not to make us panic. Honestly, I think he knew we'd all try and get his board from under him. I lived through that luckily and so did he.
