Friends have described the frantic final moments of a young surfer who was attacked by two enormous sharks off the coast of Gracetown, Australia right before their eyes.

The witnesses say that 29-year-old Brad Smith was surfing off Left Handers Beach, around 150 miles south of Perth, when a massive great white shark "as wide as a shark" ambushed him, biting his surfboard in half in 2012.

His friends watched in horror as Smith fell into the waters, thrashing around in a mixture of water and blood.

He desperately tried to fight back, pushing the creature away and striking it in the nose with his fists.

But soon his friends noticed a second shark approaching. After approximately 45 seconds of fighting, they say Smith was dragged beneath the surface as the water turned a deep red,reports the Mirror.

Then, Smith's lifeless body floated to the surface, "bitten in half".

His friends courageously braved the shark-infested waters to retrieve what was left of Smith, warning other surfers, "Don't go in there, someone's been bitten."

Cameron Rowe, 17, said: "There was nothing we could do to help him. At first I saw one shark and thought it was one of the usual ones you see swimming-around, reef sharks, which don't cause you any trouble.

"But these things were massive. When the first one came up a bit I could see its fin and it was almost a yard high.

"When it came out of the water with Brad still fighting it, I could see its body was about the width of a car and its open jaws were as wide as a man's arm.
