A GREAT white shark sighting at Kellidie Bay has led to calls for caution for people using the popular fishing and watersport spot.
Port Lincoln recreational fisher Matt Williamson was fishing at Kellidie Bay in September when the shark nudged his boat.
Mr Williamson said the great white gave his boat a “couple of little taps” before it swam off, but it came back again.
“I threw my anchor at it, and it shot off,” he said.
“It wasn’t the best thing to happen.”
Mr Williamson was fishing in a nine foot tinny at the time, and said it was the first time he had seen a great white shark while fishing.
Coffin Bay Oyster Farm owner Lester Marshall said he had never heard of a shark being sighted in Kellidie Bay.
He said he had since made phone calls to retired commercial fisherman who used to operate in the area, and neither themselves or their commercial fishing fathers had ever seen a shark in Kellidie Bay.
“It’s never been seen before, and we may never see another one again,” he said.
“There is no doubt there are more sharks around then there was 20 years ago.”
Mr Marshall said until the shark sighting, he had never though about the risk of a shark in Kellidie Bay before.
“Sting rays, sure ... but not getting eaten,” he said.
“Does this mean every year, there might be a chance white pointer may swim into Kellidie Bay?”
Mr Marshall has now told his employees not to take unnecessary risks while working on oyster racks.
“A couple of my workers are not worried at all, but a couple of my younger lads are freaking,” he said.
“I said ‘don’t take any unnecessary risks, don’t work in shoulder depths when you have nothing around you’.
“Amongst the racks themselves, you feel fairly safe, but when you have a high tide coming in, guys working at shoulder deep height ... you feel a bit more exposed, there is a potential risk.
“You just have to minimise the risk.”
