Untouchable backstroke queen Kaylee McKeown completed the backstroke treble at the Australian Swimming Trials, while Kyle Chalmers blitzed the 100m freestyle and Lani Pallister swam a sizzling 800m freestyle.
Kaylee was under her own 200m backstroke world record pace at the halfway mark in Adelaide before easing up to touch in 2mins 04.47secs with Hannah Fredericks also booking a seat to Singapore, touching in 2:09.54.
“I am happy with that (about racing the fastest time of the year in the world)," Kaylee said. "It's a good step in the right direction.
“I want to go to a third Olympics. I want to be on American soil and show them what the Aussies have."
Kyle, who has won a medal in the 100m free at three consecutive Olympics, including gold on debut in Rio 2016, surged home in 47.29 with Flynn Southam (47.69) also qualifying.
"Fastest time in Australia that I've ever done, so super happy with that," Kyle said. "I'm just trusting what I have been doing in training, listening to what my coaches are telling me. trusting that we've done the work."
Kyle, the 2023 world champion, has also qualified for the 50m free.
“This is my 10th year on the Australian Swimming Team now, this is my 14th Trials. It goes so quickly. It doesn't feel like it was that long ago when I was arriving here for London 2012 Trials."
With Ariarne Titmus taking the season off, Lani smashed her teammate's Australian record in the 800m, ripping 8:10.84, the third fastest time ever.
“I've wanted that record for so long," Lani said. “I have a lot to thank her for with what she's done in inspiring me as an athlete.”
