Shark experts say a culling program would not stop fatal attacks in Australia.
The call to cull sharks comes after Ben Linden, 24, became the fifth person to be killed by a shark in Western Australian in just 10 months.
Mr Linden was attacked on Saturday while paddling his surfboard near Wedge Island, 160km north of Perth.
"We have allocated some $14 million extra to get a better understanding of the great white sharks and the reasons why the fatalities are occurring," said State Fisheries Minister Norman Moore. "I wonder if research might tell us that there are now much greater number of great whites than ever before, and maybe we should look at whether they should remain a protected species."
However, Janita Enevoldsen from the Wilderness Society of Western Australia says taking the sharks off the protected species list will not help.
"We need to really understand them and not resort to the neanderthal reaction of a hunt and kill," she told ABC News.
Fisheries officers are trying to locate the shark that attacked Mr Linden. It will be killed if it is found.
