Sweetheart was the name given to a 5.1 metre saltwater crocodile responsible for a series of attacks on boats in Australia between 1974 and 1979. Sweetheart attacked outboard motors, dinghies, and fishing boats. In July 1979, Sweetheart was finally caught alive by a team from the Territory Parks and Wildlife Commission, but drowned while being transported when he became tangled with a log. The crocodile's mounted body is now on permanent display at the Museum and Art Gallery of the Northern Territory.
The story of Sweetheart has been taken with considerable poetic licence by Greg McLean, director of the film Wolf Creek, and made into a film titled Rogue.
