Safest place in Australia?

Im pretty new to surfing so I have very little experience with surf travel. Also here in England we don't really have anything to worry about so maybe the stuff in other countries gets exagerated. Obviously ive heard loads of good stuff about Aus, but have also heard about sharks, jellys, stonefish, etc. I was just wondering where the safest place would be (in the water) for me to surf. Or is it ok in most places? Any info would be great. Im probably just being a wimp but......
