Breaststroker Leisel Jones gave the 200 metre world record a fright and shattered her own Australian mark with a sizzling performance at the Queensland swimming titles at Chandler.

Jones stamped her authority on the race early and was one and a half seconds under world record pace after the first 100 metres.

She was less than second under the world mark with 50 metres to go but faded on the last lap to hit the wall in 2:23.72 -- under the old Australian record of 2:24.33 but 0.8 slower than the world record.

The 18-year-old Jones said she went out too hard, too early and a bigger crowd and better opposition may have given her an extra boost.

"It was a bid sad it was the last event of the night and nobody was here to see it and it is sort of hard when there is not a massive field you're swimming up against," Jones said.

"I should have calmed down after the first 50 but that's something we can work on in training."

Pint-sized Alice Mills put friendship on hold for a little over 25 seconds to win the hotly contested women's 50 metre freestyle final.

The 17-year-old Mills defeated three of her Australian team-mates in a time of 25.31 seconds relegating fellow Queenslanders Liby Lenton (25.51) and Jodie Henry (25.78) to the minor placings while veteran Sarah Ryan was fourth in a time of 26.08.

She said it was all business as soon as she stepped on the blocks and tonight's victory could provide a slight psychological advantage over her rivals at the upcoming Olympic trials.

"We're all mates until we walk out. I don't care how much I like them when we are racing," Mills said.
