Australia Breaks Their Own 4×100 Mixed Free Relay World Record In A Time Of 3:18.83

2023 WORLD AQUATICS CHAMPIONSHIPS

On Saturday night, the Australian team of Jack Cartwright, Kyle Chalmers, Shayna Jack, and Mollie O’Callaghan broke their country’s old world record in the 4×100 free relay, combining for a time of 3:18.83. Cartright, Chalmers, and O’Callaghan were all only the previous world-record-breaking relay, which posted a time of 3:19.38.

Although Cartwright touched in third behind America’s Jack Alexy and Great Britain’s Matt Richards, Chalmers posted the fastest male split of the field to help move the Aussies up to second place. Then, Jack and O’Callaghan recorded the only two sub-52 splits on the women’s side to give their team the clear lead.

In the end, the Aussies won by 1.99 seconds.

Splits Comparison:

Australia, 2023 World Championships (current world record) Australia, 2022 World Championships (former world record)
Jack Cartwright – 48.14 Jack Cartwright – 48.12
Kyle Chalmers – 47.25 Kyle Chalmers – 46.98

Mollie O’Callaghan – 51.71 Mollie O’Callaghan – 52.03

This relay is Australia’s third relay world record at these World Championships, as they previously broke the women’s 4×100 and 4×200 free relay world records earlier on in the meet.

Shayna should swim the anchor leg in the women’s 4×100 medley relay for Australia in the finals.

She hasn’t split a 52 all week. She was a 51.66 in her only relay heat lol.

If someone last week had told me Jack wouldn’t split a 52 the whole meet I would have been disappointed lol.

52.28 lead off in the women’s 4×100 free relay heats is her slowest swim of the week.

If the 2026 Comm Games were going ahead in Australia, I think King Kyle might have gone on to that. Now I doubt he’ll continue after Paris.

Madi Wilson loses her third WR this week. Ironically she has won a gold medal for every WR she lost because she’s swum in the heats of every one.

If Chalmers continues after Paris they might be able to lower this record again. Especially if McEvoy successfully transitions his new training to the 100.
