AUSTRALIA set a world record of three minutes 30.66 seconds in the men's 4x100 metre medley relay at the World short course swimming championships in Gothenburg yesterday.

The quartet of Adrian Radley, Phil Rodgers, Geoff Huegill and Michael Klim beat the old record of 3:30.91 established by another Australian line up, which included Radley, Huegill and Klim, last December in Melbourne.
