Queenslander Jessicah Schipper triumphed in the battle of Australian swimming's wonder women at the national shortcourse titles in Melbourne, edging out two other world champions for a Commonwealth record.

Schipper beat Libby Lenton and Danni Miatke to win the women's 100 metres butterfly gold medal - her 56.56 seconds erasing Petria Thomas' old Commonwealth shortcourse mark and just .22sec outside the world record.

The 18-year-old from Redcliffe wore down Lenton, who went out hard and was on world record pace for the first 50m of the race.

But while Lenton has broken two world records at this meet - both in the 100m freestyle - Schipper posted her second near-miss after coming within a whisker in her women's 200m butterfly victory on the opening night.

"I haven't had very much luck with the world records on this trip - close but not close enough," Schipper said.

"It gives me something to work for. Going to the world shortcourse (in Shanghai next April), hopefully I'll get it there."

Not content with a punishing three-week schedule including the world championships and Duel in the Pool meet, Lenton backed up 10 minutes after the 100m butterfly to win the 50m freestyle.

"I knew as soon as I touched the wall (in the 100m butterfly) that I was in a whole new world of pain and that I was really going to have to put my head down for the 50m and try to win it," Lenton said.

Both Lenton and Schipper - like most of Australia's swimmers - are off for well-earned breaks after a gruelling and successful three weeks.

Another of Australia's world champions, Leisel Jones, also broke through the pain barrier for her second individual gold medal at this meet.
