An injured teenager has been rescued after falling off a cliff at a national park in the Northern Territory.
The 17-year-old was stranded about 10 metres from the top of Florence Falls in Litchfield National Park, NT police said on Thursday.
He was rescued by emergency service volunteers who hauled him to the top of the waterfall using ropes.
The teen suffered non-life-threatening injuries and was flown to Royal Darwin Hospital in a rescue helicopter.
The crocodile-free Florence Falls is a popular swimming spot for tourists and locals in Litchfield National Park, about 100 kilometres southwest of Darwin.
Youths are often seen climbing to the top of cliffs and jumping into the waterhole about 20 metres below.
