Aussie swimming star Kaylee McKeown has broken her second world record in as many days as her stunning hot streak continued.

Kaylee McKeown broke her own world record.

Kaylee McKeown has done it again, breaking her second swimming world record in as many days as her sensational form continues.

A day after breaking the 50m backstroke world record, McKeown did it again at the World Cup event in Budapest, breaking her own 100m backstroke world record.

In a blistering swim, McKeown touched in a time of 57.33 seconds to shave 0.12sec off the global mark she set in 2021 at the Australian trials for the Tokyo Olympics.

She now holds seven of the top 10 times ever recorded in the 100m backstroke.

The 22-year-old is surely now a certainty to win the Female World Swimmer of the Year, completing an Aussie hat-trick after Emma McKeon and Ariarne Titmus won the award in the last two years.

McKeown now holds the world records in the 50m, 100m and 200m backstroke — a remarkable feat that cements her status as the undisputed queen of backstroke.

She is just the second swimmer to hold all three backstroke world records after American Lenny Krayzelburg broke the 50-100-200 treble at the 1999 Pan Pacific Championships.

McKeown is the second woman to hold world records in every event of one stroke after South Africa’s Penny Heyns held the 50m, 100m and 200m breaststroke records in the 1990s and 2000s.

McKeown won gold in the 100m and 200m backstroke in Tokyo, and will be favoured to repeat that double at next year’s Paris Olympics.

She won both those events as well as the 50m backstroke at this year’s world championships in Japan, holding off American rival Regan Smith.

McKeown is currently the world long course and short course champion, Commonwealth Games champion and world record holder in her pet events.

She also holds the 200m backstroke short course world record.
