It was a 1-2 finish for Australia, with Pearse’s teammate Alex Saffy taking away gold, edging the Bamawm Extension swimmer out of gold by just three tenths of a second.
Canadian swimmer Jack Gill rounded out the podium, finishing in a time of 1 minute 00.3 seconds.
The final took place early morning Saturday, July 25 Australian time.
Pearse had got the better of Saffy by 0.62 seconds at the Birmingham 2022 Commonwealth Games, before Saffy turned the tables at the Paris 2024 Paralympics, narrowly claiming bronze ahead of his compatriot.
Taking to Instagram shortly after touching the wall, Pearse paid tribute to his training partner, writing: “Proud of you lil bro.”
As of Sunday morning AEST, Australia is well out in front on the medal tally, Pearse and Saffy contributing to our 23 medals, leading second-ranked England with 15.
The gold medal disparity is even higher, with Australia claiming 12 of the 23 golds contested so far, England’s three the next best.
