A desperate search is underway for a 20-year-old man who went for a New Year's Eve dip in a river and vanished. Police said the young man was swimming in waist-deep water with a group of friends in Gympie, Queensland, overnight to celebrate the New Year. The group were using vehicle headlights to illuminate the Mary River at the corner of Traveston Crossing Road and Dobson Road near their camping ground at Kybong just after midnight.
