16-Year Old Record Setter Sienna Toohey Leads 30 Aussies for World Junior Swimming Champs

Swimming Australia has announced a roster of 30 athletes and 7 coaches for the 2025 World Junior Swimming Championships. The event will take place from August 19-24 in Otopeni, Romania.

This is the exact same roster size as the one Australia sent to the 2023 Championships, which ultimately put five swimmers on the 2024 Olympic team: Iona Anderson, Jaclyn Barclay, Jamie Perkins, Flynn Southam, Olivia Wunsch.

This year’s team is headlined by Sienna Toohey, who led six swimmers under the breaststroke qualifying times at the selection meet, the Australian Age and Open Championships, earlier this month.

The 16-year-old won four gold and set two national records including a  head-turning 1:07.04 in the girls 100m breaststroke that broke Dolphins’ great Leisel Jones 23-year-old national age record (1:07.31). She then backed this up with a national record in the 50m breaststroke (30.73).

The youngest swimmers on the team are Christopher Montana, 15, from Trinity Grammar and Heidi Shumack, 15, from SOPAC, while the eldest is WA’s Tex Cross, Qld’s Oliver Linde and NSW’s Jessica Cole – all 18 years of age.

Cole is the lone returning member of the 2023: she finished 5th in the 200 fly in Netanya in 2023. That Australian team finished 2nd in the overall medal standings behind the United States with 9 gold, 7 silver, and 8 bronze medals. That was the country’s most ever total medals at this meet (24), though they did win 1 more gold in 2013 to lead the medals table.

“With the tightening up of qualifying times,  I’d like to see a greater percentage of athletes qualifying for finals, and also a greater percentage of conversions, and by this I mean an improvement in their times from national age championships through to Junior World Championship finals,” said the squad’s head coach Simon Cusack.

Led by Cusack, team coaches selected for the tour are: Ashley Delaney (St Andrews), Deb Jones (Fenix), James Greathead (SOPAC), John Jordan (Bendigo East), Tom Fraser-Holmes (Griffith Uni) and Wayne Gould (Albury). Brooke Kemp, WA, will also join the team as a scholarship coach.
