Cody Simpson qualified for his first senior international team after sealing third in the 100m butterfly at the Australian Swimming Championships in Adelaide on Wednesday (18 May).
While the former national age grade champion missed out on selection for the World Championships team, his finish was good enough to be named on the Dolphins' 2022 Commonwealth Games roster.
Mack Horton, Kyle Chalmers and Shayna Jack all finished second to secure their berths on the team this summer.
Two-time Olympic medallist Matt Temple (51.50) and Rio 2016 freestyle Olympic gold medallist Chalmers (51.67) clinched first and second respectively in the men's 100 fly.
But with Chalmers having ruled himself out of the Worlds in order to focus on the Commonwealth Games, and all three podium finishers in the race having achieved the FINA 'A' qualification time, Simpson could now be called up to make his first senior international team in Budapest.
There was an exciting finish in the women's 100 freestyle, where Mollie O'Callaghan took top spot in 52.49.
Her time was just 0.11 quicker than fellow qualifier Shayna Jack, who completed a successful return from her two-year suspension, while Meg Harris finished third with 53.09.
Elsewhere, Mack Horton showed that he is back to near his best after finishing second with 3:44:06 in the men's 400m freestyle.
After missing out on qualification for the Tokyo 2020 Olympics, the Rio 2016 Olympic champion qualifies alongside winner Elijah Winnington, who touched home in 3:43:10.
Jenna Straunch came from behind to claim victory in the women's 100 breaststroke in 1:06:69.
Midway point leader Chelsea Hodges, who helped the Australian women's 4x100 medley relay team win gold in Tokyo, had to settle for third, with Abbey Harkin the second automatic qualifier in second.
There was another rejuvenated performance by Mitch Larkin who finished second to teenager Joshua Edwards-Smith by 0.08 in the men's 200 backstroke.
There was a huge PB for Thomas Nowakowski, who swum under 22 seconds for the first time to win the men's 100m freestyle in 21.86.
Grayson Bell sealed second in 22.08.
In the absence of Ariarne Titmus, reigning world junior champion Lani Pallister took first place in the women's 800 freestyle in 8:17:77, with Kiah Melverton in second with 8:22:25.
