A woman has scared away a salt water crocodile, which was swimming towards her and her dog, by slapping her flip-flop at it.

Crocodile enthusiast Lundon Anlezark, who filmed the incident, said: "I don't think she realised how dangerous this kind of behaviour is".

It is thought that are at least 120 crocodiles in this stretch of the East Alligator River, in Kakadu National Park.

The last fatal attack there was in 1987.
