Australia set their second relay Commonwealth Games record in two days with a dominant swim in the mixed 4×100 free relay tonight. Their time of 3:19.36 sliced nearly two seconds off the previous mark from the 2022 Games and beat the field by over four seconds tonight.

Flynn Southam got them off to a great start with a 47.29 leadoff, a second and a half faster than William Yang‘s 48.80 from the 2022 record. That is his second-fastest swim ever, behind only his 47.09 leadoff and Games record from the 4×100 free relay last night.

Kyle Chalmers was slightly slower than his 47.55 split from four years ago with a 47.62 on the second leg tonight. Shayna Jack (52.42) and Meg Harris (52.03) were around two tenths of a second each faster than Mollie O’Callaghan (52.62) and Emma McKeon (52.21).

Split Comparison

Jack and Chalmers both featured on the Australian record swim three years ago, and Chalmers has featured on all three of the above swims.

Tonight’s swim ranks as the second-fastest performance in Australian history, behind only that 3:18.83 they swam at the 2023 World Championships. It is also the #3 swim in world history, with Australia holding the #2, #3, and #4 swims ever, although World Aquatics have announced they are dropping the event from the World Championships schedule going forward.
