A 15-year-old girl who was catapulted into the air by a 15ft shark has likened the attack to a Jaws film.
Sarah Williams was in her kayak off the coast near Normanville, south of Adelaide, in South Australia state, when the great white struck.
All of a sudden, a big bang from the bottom and a shark had taken me. Not that I knew it was a shark," she told the Nine Network.
"Next thing I knew I was in the water with the shark and I was watching it attack my kayak.
"When I was in the air - because it threw me up in the air - it felt like I was watching the typical Jaws movie.
"I saw it when I was in the water with it. I saw what it was and I saw its fin."
Her father Chris and brother Mitchell Clarke-Williams looked on in horror as they saw the shark thrashing about and lunging at the kayak as the teenager screamed.
Mr Williams said: "All of a sudden this awful sound of something hitting the plastic of the kayak. I had my back to her.
"I've turn around and I see Sarah hit the water, because it has launched her out of the water, he's come up and hit from underneath."
Fighting back tears, he continued: "This scream. You can't describe. You cannot describe what this scream was like.
"So I just turned around, pulled the motor - thank God it started the first pull - and I just hit it as hard as I can straight back to her.
"The shark's come back and had another go at her, thrashing around, and she's screaming and trying to get back onto the kayak."
