  • Heard in the footage claiming they’ve never seen a shark so big in popular bay

Astonishing footage has emerged of a shark hunting down a seal near a popular swimming spot off Victoria’s Mornington Peninsula.

A group of mates enjoying a day on a boat filmed the encounter of the bronze whaler violently thrashing around just metres away from them in Port Phillip Bay off Portsea on the weekend.

‘Oh my God! Dad, stop, stop!’ a man is heard exclaiming in the footage. ‘It’s chasing a seal! Oh my God! Holey moley, this is crazy!’

The men were shocked as to just how big the shark (pictured)  was when it got closer to the boat

The men get a closer glimpse of just how big the predator is as the shark swims closer to the boat as it aggressively chases its prey.

‘What is this! Oh my God, that’s massive!’ the man excitedly says. ‘It’s right there!’

Another mate suggested the shark may be chasing fish rather than a seal.

‘Well whatever it is, it’s chasing it,’ the man replies. 

Another video shows the men’s horror of just how close the shark came to the boat.

‘Oh s**t, I’ve never seen one that f**king big,’ another man says.

‘That’s enough for me! As long as he stays down there.’ 

Despite their size and aggressive predatory behavior, bronzed whalers, also known as copper sharks aren’t usually a threat to humans.

Just one fatal attack has been recorded in Australia – at Bunker Bay off Western Australia’s coast in 2011.
