Records continued to fall on day three of the able-bodied competition at the 2025 Australian Age Championships.

16-year-old Henry Allan ripped a lifetime best of 53.73 to take his age category’s 100m backstroke event, establishing a new Australian and All Comers Age Record in the process.

Representing Bendigo East Swimming Club, the John Jordan-coached Allan opened in 25.96 and closed in 27.77 to register his first-ever outing under the 54-second barrier.

Entering this competition, Allan’s previous lifetime best and record stood at the 54.23 put up at last month’s New South Wales State Open Championships.

For additional perspective, Allan’s new 53.73 PB would rank him as the 2nd-swiftest U.S. 15-and-16-year-old boy in history.

The Aussie national record for 14-year-old boys’ 50m backstroke also bit the dust, courtesy of Bryce Krause.

Toowoomba’s Krause stopped the clock at 26.41 to beat his competitors by over a second, lowering his own previous benchmark of 26.67 turned in earlier this year.

Koa Stotz also joined the record-breaking party, notching a new standard en route to winning the 14-year-old boys’ 100m breaststroke.

In his second record-breaking performance of the week, Stotz punched a result of 1:04.21, splitting 30.62/33.59 in the process.

Trinity Grammar’s Christopher Montana also claimed his second national record of the competition, taking the 15-year-old boys’ 50m breaststroke.

Montana registered 28.47 to set himself apart from the field, overtaking his previous lifetime best and national age record of 28.54 en route to gold.

Finally, Ainsley Trotter of Bond University made it happen in the 17-year-old girls’ 50m backstroke.

Trotter posted a swift 27.88 to set a new All Comers Age Record, erasing the former time of 28.08 that Olympic gold medalist Mollie O’Callaghan established four years ago.
