Went down whitehills beach today, swell was huge, beach was busy with campers and wind came up too early, a good day was had though with some nice fresh herring  on the BBQ and a couple of coldies. Noticed 3 choppers and the mandurah sea rescue boat hanging around 1 area for quite some time, presumed a shark or two in the area but seemed odd that the police helicopter would be there just for a shark, anyone know more?
