INCREDIBLE footage has emerged of brave WA fishermen returning a tiger shark to the sea.

As some West Australians call for a cull to reduce the number of man-eating sharks off our coast, these anglers put their lives in danger to save the beast.

At one stage one of the fishermen sits on the 3m shark as it thrashes on the beach at Maud's Landing in Coral Bay and pries its mouth as his friend attempts to unhook it from a fishing line.

The video was shot on Wednesday, according to locals.

A red towel is placed on the shark's head as the group use pliers to release it as onlookers filming the rescue.

After almost three minutes the shark is eventually freed and the group pull it into the sea by its tail.

The creature struggles in the shallows for another minute before it eventually returns to the deep, to the delight of the applauding crowd.

The 4 minutes and 53 seconds clip - called "400kg Tiger Shark caught in Western Australia" - was posted on YouTube on Thursday.

A description of the video says: "A 4m 400kg Tiger Shark was accidentally caught off the coast of Western Australia in popular fishing area in the late afternoon.

"The local experienced fishermen came together ensuring the safe and humane release of this beautiful animal.

"The community cheered as the Tiger was successfully released back into the water."

A Coral Bay businesswoman, who didn't want to be named, said the shark had been caught accidentally and probably weighed under 200kg.
