Bowden made his Australian representative debut in 2011 when he was selected in the coxless four to race at the 2011 Junior World Rowing Championships at Eton Dorney. That crew placed thirteenth overall.[10]
In early 2014 World Rowing Cup I was held in Sydney and Bowden was vying for selection in the Australian senior squad. All the Australian sweep oarsmen contested events in small boats and Bowden's coxless pair finished fifth in their final. Also at that regatta he raced in the #2 Australian eight which finished fourth.[10] At the 2016 World University Championships in Poznan, Bowden raced as Australia's coxless pair with Angus Moore. They won a bronze medal.[11]
In 2017 he made the Australian senior squad and was competing for a seat in the men's eight during the European racing season. He
was in the two seat of the eight when they finished in 4th place at World Rowing Cup II. Then at WRC III he raced in a coxed pair with Ben Coombs and James Rook to a silver medal and also in a coxless pair to 13th place. Bowden was back in the Australian men's eight when they finished eight at the 2017 World Rowing Championships.[10]
In 2018 Bowden made another senior squad appearance in an Australian #2 men's coxless four when they rowed in the heat and repechage at World Rowing Cup III in Lucerne.[10] It was his final Australian representative showing, although he travelled with the squad to the World Championships that year as the sweep reserve.[12]
