BEIJING, Aug 17 (Reuters) - Australia set a world record of three minutes, 52.69 seconds to win the gold medal in the women's 4x100 metres medley relay at the Beijing Olympics on Sunday.

The United States finished second in 3:53.30, also under the old world record, to give Natalie Coughlin her sixth medal of the Games, including one gold, and 41-year-old Dara Torres her third silver of the Games.

China finished third to collect the bronze medal in 3:56.11.
