Move over Ian Thorpe and Grant Hackett.

It's the women of the Australian swimming team who are grabbing the attention in the lead-up to July's world championships in Spain.

The second night of the three-day grand prix meet in Cairns belonged to Alice Mills, who turned 17 on Friday.

She took out the 50 metres butterfly and backed up after six races to claim the 100m freestyle, beating Commonwealth record holder Jodie Henry in 55.92sec.

Four races later she won the 200m individual medley ahead of golden girl Leisel Jones.

She also claimed the scalps of Giaan Rooney, Lisbeth Lenton and Henry to take out the 150m freestyle on Friday night.

Mills said she was worried coming into Saturday night's event with five races on her schedule, including two relays.

"But I didn't let it get to me and I was a bit surprised how well I went in all of them," she said.

"I'm happy with the times I went, it's pretty fast for this time of season, so it's all good.

"It's all going very well so I'm looking forward to the worlds."
