Jaba,
I agree with you on the rock fishing issue. (Particularly here in NSW where quite a few rock fishermen have drowned in recent years.) I reckon that it should be an educational rather than an enforcement issue. Modern 'Personal Floatation Devices' (PFD's) are available for under $100-00 from your local BCF store etc. They are very comfortable to wear and may save your life, if one is washed into the ocean.
