World record breaker Leisel Jones hits the water for the first time at the world championships trials in her hometown of Brisbane on Monday.

The breaststroke queen has the chance to increase the large gap she already has on her rivals in the semi-finals of the 100m at Chandler's Aquatic Centre.

However she is not the only world record holder in action with Jess Schipper battling it out with Libby Lenton in Monday night's 100m butterfly final.

Schipper, the 200m record holder, is the reigning world champion in the event and is aiming on closing in on Dutchwoman Inge de Brujin's world mark of 56.61s.

Lenton has been doing extra work in butterfly and will push Schipper all the way.

Meanwhile Australia's leading breaststroker Brenton Rickard will be aiming to break the magical one minute barrier in the 100m final.

Grant Hackett, who pipped Craig Stevens to win the 400m freestyle, returns to action in the 200m, aiming to qualify for a spot in the 4x200m relay team.

Hackett has ditched the individual event at next year's world championships in Melbourne despite winning silver over four laps at last year's world titles in Montreal.

Linda MacKenzie was the other winner on Sunday night, finishing half a second outside Tracey Wickham's 28-year-old national record in the 400m freestyle.
