While GNS may be considered 'placid' by some, many spearos have had run-ins with this underestimated shark - whether they have shot fish in the area or not. A particularly hairy time for GNS is around the full moon, and mating times. Often, Spearos don't report the attacks of GNS as the information may lead to more closures for GNS habitats. Below is a recent story from news.com.au
A MAN bitten by a shark while spear fishing on the NSW mid-north coast has undergone surgery.
He was taken to Port Macquarie Hospital and underwent surgery on Monday to puncture wounds on his leg and is expected to make a full recovery.
Fish Rock Dive Centre instructor Jake Wilton, who dives with grey nurse sharks daily in the Green Island critical habitat area, said they were placid.He said the man who was attacked had a dead fish attached to his weight belt, which attracted the shark.
"It wasn't an attack, the shark was just hungry,'' Mr Wilton said. "I dive with the sharks every day and I've never had a problem.Spear fisherman need to make sure they attach dead fish to floatlines, not to their weight belts. Otherwise it's like dangling a sausage in front of a hungry kookaburra.''
