Briton Josh Jones ‘downs 10 beers’ then jumps off cliff at Australia's Jim Jim Falls

This is the moment a Briton who had downed “about 10 beers” suffered multiple injuries leaping from a waterfall at a remote Australian beauty spot.

Josh Jones, 25, broke his left leg in two places and suffered a dislocated knee and facial injuries when he plunged 100ft in Kakadu National Park in Northern Territory.

A doctor, who had been visiting Jim Jim Falls with three medical students, went to the rescue as he floundered in the water. They constructed a stretcher from wood and denim shorts and carried him to safety.

Mr Jones, from Yorkshire, told ABC: “I saw the ledge and thought, ‘Hey, that’s possible to jump off.’ It was just pure impact [when I hit the water]. It took the wind out of me, I came up and the left leg didn’t feel too good.

“I swam over to the edge, got a bit of air and the left foot was out far to the left. I thought, ‘Yeah, that’s got to be broken.’ ”

Mr Jones, who said he was “gutted” by the incident on Saturday, was taken to the Jabiru Clinic before being airlifted to the Royal Darwin Hospital a further 160 miles away.

The Briton, who ABC reported had downed “about 10 beers”, added: “[I want to thank] all the guys who came to help me, four doctors and everything — strapped me up, pulled my leg straight and we all got back to the camp. They made up a homemade sling, a stretcher, and dragged me all the way back for hours.”

Onlooker Daniel Fitzgerald said: “It’s about 900 metres or so, but you’ve got to go over these huge big boulders and there’s no path there whatsoever.

“He’s lucky to survive. I thought he would hit the bottom of the cliff and not the water.”

A Kakadu National Park spokesman said visitors were encouraged to “follow safety directions, notices and warnings signs, and not to take unnecessary risks that may put you and others in danger”.

The national park, a Unesco world heritage site, is a popular tourist destination due to its 20,000-year-old indigenous rock art and spectacular landscape.

Crocodiles are typically considered to be its main danger.
