Fisherman have predicted more deadly shark attacks this summer.

“They’re in plague proportions and they're hungry,” Queensland’s most experienced master fisherman, John Reid, told A Current Affair .

“If we don’t do anything about it there will be more people taken by sharks.”

At the other end of Queensland – on the Great Barrier Reef – another commercial fisherman, Walter Putzka, says, "We have up to about 50 large sharks circling our 28-foot fishing vessel at any one time and they are fighting and mauling for food as well as bashing the boat.”

What’s even more alarming is that Mr Reid says he wrote to the State Government in January warning them of the dangers.

He said the response was "silence".

"I heard nothing and now three people have been attacked in the Whitsundays – one of them is dead," he said.

A series of horrific shark attacks has led to calls to cull sharks.

"When is enough enough?" Hinkler MP Keith Pitt said.

"Do we have to wait for a child to be taken in the shallows ?”

At the same time Mr Pitt was being interviewed by A Current Affair, young mum Alisha Samuel was videoing a small tiger shark in the shallow water on Bribie Island north of Brisbane.

“I was swimming with my two-year-old son when someone said, 'There’s a shark behind you'," Alisha said.

"I grabbed him and raced for the shore and when I looked back there it was swimming calmly in the shallows not nervous about us at all."

Alicia’s partner Joey called lifesavers, who followed the shark out to sea and closed the beach.

It was the second beach in the area to be closed in one day due to a shark scare.

Kayaker Kyle Roberts was knocked out of his kayak in Caloundra by a monster shark – believed to be a four-metre tiger shark – just hours before.

“That kayaker was lucky,” Mr Reid said.

“He says the shark bumped his vessel and then started circling. Luckily he had a phone and could call for help.”

Across the border in Ballina, New South Wales, a surfer also made a lucky escape last week.

Lee Johnson managed to bash a shark with his surf board and catch a wave to shore with only a minor injury.

“I thought it was all over,” an emotional Mr Johnson said in a bedside press conference.

After the third attack at Cid Harbour in the Whitsundays, the Queensland government called a meeting with local authorities to find a solution.

Ruling out drum lines, the meeting decided to ban swimming in Cid Harbour and spend $250,000 on a study to study the migration habits of sharks in the area.

“A time-wasting talk fest won’t scare the predators away,” Mr Reid said.

“We have to cull them now.”

Mr Reid blamed government restrictions on fishing for the growing numbers of sharks.

“There are fewer fisherman out there, shark numbers have prospered and now they are moving in closer to get more food,” he said.

“Greenies seem to think sharks are endangered, well, I don’t see many of them out there swimming around – maybe they’d change their minds if they did.”

John’s fishing logbooks have repeated entries commenting on the number of sharks in the water off the Sunshine Coast.

Seaworld’s Trevor Long says one solution is better education.

“There should be more signs along the coast,” Mr Long said.

"Warning people that sharks frequent these areas so people can make an informed decision on going to the beach.”

A spokesman for Queensland’s Fisheries Minister Mark Furner said there has been no apparent increase in shark numbers.

“There is no evidence that a shark cull would make our beaches safer,” the spokesman said.

“The best advice is to only swim or surf at patrolled beaches, do not swim at dawn or dusk or at night and leave the water if there is a shark sighting.”

But Mr Reid isn’t convinced it’s safe to swim.
