Sophie Paterson said she would have to be "quite twisted" to have been impressed by the stunt, during which Mr De Paauw was attacked by a crocodile after he jumped into the Johnstone River to prove to her that Australians were less likely to be attacked by crocodiles than backpackers.

"Risking your life, there is nothing funny about that ... in all honesty, it was a horrific experience. I was pretty shaken up," she told the Seven Network.

However, the injured 18-year-old, who was in Cairns hospital with a broken arm after the attack, told Today he had managed to line up a date with the "beautiful backpacker".

"She said she would go out with me to the movies, yeah," he said on Tuesday morning.

"She is really good looking and been kind to me the night before."

The teen was expected to remain in hospital over the next few days.
