The 2008 Telstra Australian Swimming Championships were held at the Sydney Olympic Park Aquatic Centre in Sydney, New South Wales, Australia from 22–29 March 2008. The championships were used as the Australian trials for the 2008 Olympic Games squad.
Like all previous Australian swimming trials, the championships program mirrored the 2008 Olympic swimming program with the addition of the non-Olympic events – 50 m backstroke, breaststroke and butterfly; 800 m freestyle (men) and 1500 m freestyle (women).
