Leah O'Brien, a 17-year-old from Perth, has shattered a 57-year-old under-18 100m record, previously held by Australian Olympic legend Raelene Boyle. O'Brien clocked an astonishing 11.14 seconds at the Australian Junior Athletics Championships in her home city, a time that places her ninth on the world under-18 list and equal fourth on the Australian all-time open 100m list, level with Olympic gold medallist Sally Pearson.
The prodigious sprinter achieved this feat on Tuesday, April 8, 2025, at the Australian Athletics Championships. Her record-breaking performance also saw her achieve a personal best, a result that apparently surprised even herself. The time of 11.14 seconds eclipsed Boyle's long-standing mark of 11.20 seconds, set during the Mexico City Olympics in 1968.
A Double Crown and a Glimpse of the Future
O'Brien's triumph was not limited to the 100m dash. She also secured the Under 18 Girls 200m title on Saturday, April 5, 2025, with a time of 23.37 seconds. This gives her a sprint double within her age group for the 2025 championships.

In the 100m final, O'Brien outpaced World Under 20 Championships representative Thewbelle Philp, who finished in 11.35 seconds, and Amaya Mearns, who clocked 11.45 seconds. The podium order for both the 100m and 200m events saw these three athletes finish in the same ranking.
O'Brien has openly admired top Australian sprinters like Torrie Lewis and Bree Masters, stating their social media presence is "inspirational." Her own impressive performances now position her as a contender for future national and international teams, potentially challenging for dominance in the coming decade. She has been described as a "new Perth queen of the track" and a significant figure in a potentially "golden era of Australian sprinting."
Broader Context of Australian Sprinting
The young sprinter's achievement comes at a time when Australian sprinting is showing considerable depth. Other notable talents mentioned in connection with O'Brien include Torrie Lewis, who has run faster times (11.10 seconds), Melissa Breen (11.11), and Melinda Gainsford-Taylor (11.12). The younger generation also includes Gout Gout, Lachlan Kennedy, and Jonathan Kasiano. The senior events at the championships were set to feature prominent athletes like Gout Gout, Lachlan Kennedy, and Torrie Lewis, highlighting the growing strength of Australian track and field.

In the Under 18 Boys 100m final, Kelechi Ekwomadu from South Australia claimed victory in 10.40 seconds, followed by Jonathan Kasiano (QLD) in 10.54 seconds, and Oliver Facer (NSW) in 10.58 seconds.
A Meeting of Generations
Remarkably, Raelene Boyle herself met with O'Brien shortly after the record was broken. Boyle, a triple Olympic silver medallist, reportedly advised the young sprinter to proceed cautiously in her career development to ensure longevity. O'Brien expressed that breaking Boyle's record was "an honour."
