AusTriathlon is delighted to announce the selection of the Australian Junior and U23 Teams who will represent the green and gold at the 2025 World Triathlon Championship Finals, set to take place in Wollongong this October.
The home World Championships Finals will provide a once-in-a-lifetime opportunity for Australia’s brightest emerging talent to compete on the world stage in front of a home crowd.
One of the World Championships debutants in the Junior Men’s Team is Jack Caldwell (NSW), who has had a stellar comeback season after injury setbacks in 2024. With a clean sweep of domestic titles and the 2025 Oceania crown, Caldwell has firmly re-established himself as a force in junior triathlon.
Joining him is Zahn Spies (QLD), the 2025 QLD Junior Athlete of the Year, who secured his debut selection with a silver medal performance in Devonport.
Jack Woodberry (TAS) who now resides on the Gold Coast, returns for his second World Championships after a breakout international season, including gold at the Europe Triathlon Junior Cup in Hungary.
On the women’s side, Aspen Anderson (QLD) will bring significant international experience to the team. A dual Oceania Champion and 2025 Australian Sprint Champion, Anderson is looking to bounce back from a difficult 2024 World Championships campaign and use the experience gained from competing in Europe and the US in recent months.
Wollongong athlete Claire Spicknall (NSW), will make her World Championships debut in front of a patriotic home town crowd after transferring from surf lifesaving through the AusTriathlon/VIS Talent Transfer Program, alongside Addison Houslip (QLD), another debutant and one of the youngest competitors on the start list at the age of 16.
In the U23 ranks, Brad Course (QLD), one of the most experienced athletes selected, returns for his fourth World Championships and has enjoyed a strong 2025 campaign with standout performances on the Asia Cup circuit.
He is joined by Brayden Mercer (QLD) following a rapid rise through the ranks. The son of surf lifesaving legends Reen Corbett and Dean Mercer, Brayden transitioned to triathlon three years ago and has already recorded a World Triathlon Cup silver in Napier and a WTCS debut in Hamburg.
On the women’s side, Richelle Hill (QLD) has completed a remarkable return to elite competition, backing up her 2024 World Championship representation with victory at this year’s Oceania Championships in Devonport.
She is joined by Tara Sosinski (QLD), who returns to the U23 world stage after claiming bronze at the 2024 Oceania Sprint Championships and making her World Cup debut in Wollongong.
AusTriathlon High Performance Director, Shaun Stephens said Wollongong would provide incredible experience for the young athletes.
“To have the World Championships on home soil is a rare and exciting opportunity for our emerging athletes. It’s not only a chance to showcase their talents without international travel, which brings its own unique challenges but to compete in front of friends, family, and a passionate Australian crowd.”
“This team features an impressive mix of rising stars and experienced performers. Many of these athletes have already demonstrated they belong on the world stage with podium finishes internationally and across the Oceania region and we can’t wait to see what they can achieve in October.”
The 2025 World Triathlon Championship Finals will run from October 15–19 in Wollongong, marking the first time the Championships have been held in Australia since the Gold Coast in 2018.
