Occurrence remarks This friendly fella is known to be in the location off Cable Beach, Broome where fishing charter boats, cruise boats and private vessels anchor. The owner of the catamaran we were on lowered a ball of frozen fish carcasses into the water and sure enough this gorgeous hammerhead came to visit. We weren't far off shore, maybe 500 metres.
