Team Australia’s men’s and women’s squads have been selected for the 2025 Trial des Nations (TdN) at Tolmezzo in Italy on September 20-21, with teenage debutante Alisha Harry and returning veteran Colin Zarczynski the fresh inclusions.
Harry, from South Australia, will make her TdN debut for Team Australia alongside reigning national champion Jenna Lupo in the women’s category, while Zarczynski (NSW) will be competing in the famous event for the first time since 2015.

Zarczynski will be joined by TdN stalwarts Chris Bayles (Tas) and Connor Hogan (SA) in the men’s International Trophy division, which Team Australia won in 2017 and has finished on the podium on six other occasions.
Zarczynski, 45, is a five-time Australian champion, and finished third in the 2024 event behind first-time winner Hogan and Kyle Middleton.

Harry, 17, is an emerging star, finishing seventh in the all-gender 2024 Australian Youth title and only recently coming home strong to claim the runner-up spot in the season-opening round of the South Australian Trial3 series.
She’s also competing in the 2025 version of the famed Scottish Six Days Trial – alongside Hogan – from May 5-10 as she continues to test herself in a variety of conditions.
Alisha is the daughter of former TdN representative Adrian Harry, who finished third in the 2007 International Trophy in his final appearance for Team Australia.


Team Australia will again be managed by Phil Whittle, in what will be his 13th year at the helm.
The TdN venue is located about 90km north-east of Venice. For more information on the event, click here.
