Fishermen captured a wild feeding frenzy as dozens of hungry sharks feasted on the carcass of a dead whale.
The mesmerising moment was recorded off the coast of a tourist hotspot in Western Australia.
Travellers John Cloke and Indy Crimmins were spending some time at Norman's Bay when they noticed some sudden splashing out at sea.
While the pair were camping at Betty's Beach, northwest of Albany, they quickly set up a drone to find out what was going on in the crystal clear waters.
What they saw left the friends stunned as they filmed the mass of sharks ripping into the dead 15-metre humpback whale.
They uploaded the incredible clip to Instagram on Monday.
In the caption on the post, which now has more than 900 likes, @jindys_travels told his followers about the experience.
"Over a week ago we stayed at Betty's beach campground just outside of Albany, John went for his morning fish and noticed something in the water so he flew the drone over.
"It was a 15m humpback whale carcass! We were in shock with just how many sharks there were surrounding it we couldn’t count them all!"
The pair were later approached by ABC News to share what happened as they captured the footage.
Mr Cloke told the channel: "I was fishing off the beach and I could see this big thing bobbing in the water with birds around it, so I flew the drone out and saw it all."
He added that he believes there could have been more than "about 100 sharks around the carcass".
The beach has been closed off by Albany authorities as the decomposing carcass posed a significant risk to swimmers.
However, the remains have since washed up on the beach but the warning is still in place as the sharks may still be in close proximity to the shore.
Whale carcasses often attract a large number of sharks as they are an easy source of energy-rich food which most species will eat.
