Australia Wins Mixed Relay Gold In World Record Time On Night Three At World Juniors

It has been another golden night for Australia in the pool at the World Junior Swimming Championships in Netanya (ISR) with three Queenslanders sharing the team’s first world junior record of the meet.


Flynn Southam (Bond Swimming), Ed Sommerville (Brisbane Grammar) and Milla Jansen (Bond Swimming) were joined by newly crowned world 100m champion Olivia Wunsch (Carlile, NSW) to set a new World Junior Record in the Mixed 4x100m freestyle relay.


The Australians clocked a time of 3:24.29, to finish ahead of the USA (3:25.59) and Canada (3:29.14) – taking the team’s medal tally to 12 - four gold, six silver and two bronze. 


Southam (48.58) and Sommerville (48.54) gave the Junior Dolphins a flying start with Wunsch delivering the second fastest female split of 53.62 to rocket the Aussies to an unassailable lead.


It was then over to Jansen (who won silver in the individual behind Wunsch) to anchor and the girl from Bond delivered the knock-out blow with the fastest women’s split of the night with her 53.55.


The junior relay gold followed the world record breaking swim by the senior Dolphins (Jack Cartwright, Kyle Chalmers, Shayna Jack and Mollie O’Callaghan) in the Mixed 4x100m freestyle at the recent Fukuoka World’s – giving Australia both world records in the event – and re-enforcing its freestyle sprinting depth.


Wunsch (53.71) and Jansen (54.08) had earlier delivered their huge individual swims with their ‘1-2’ finish in the women’s 100m freestyle just 25 minutes earlier, both swimming faster than they’d ever swum, while Sommerville clocked the fastest split for the world junior champions with his second consecutive 48-point relay swim.

“It (certainly) feels good, and I couldn’t have done it without the team – Flynn, Olivia and Milla,” Sommerville said after the final.

With Southam adding: “We’re so lucky to have the depth of women in Australia and I’m hoping Ed and I can replicate that (1-2) individual result on the last night here.”

In other events, Enoch Robb (All Saints) was a close up fifth in the 100m butterfly in 52.88.
