Sprint sensation Gout Gout will double up in the 200m and 4x400m relay as part of a record 75-strong Australian team at the U20 world athletics championships in Oregon in August.
Gout, 18, has elected to prioritise the world juniors over the Commonwealth Games in Glasgow with the aim of emulating the legendary Usain Bolt, who won the 200m gold back in 2004 to kickstart his peerless career.
Gout is the U20 world record holder in the 200m - the discipline where he won silver at the previous edition of the world juniors in Peru in 2024.
The meet will take place at historic Hayward Field at the University of Oregon in Eugene, the spiritual home of US track and field.
"I'm really excited to get out there at World Athletics Under 20s," Gout said.
"I know it's a great stadium and place to run fast, and I feel confident I'll be ready to step up and make Australia proud.
"I'll be competing in the 200m but I'm also excited to join in the 4x400m on the last day."
The large squad also includes high jumper Izobelle Louison-Roe, who will be aiming to go one better than her silver from the 2024 titles in Lima.
She is entered in the high jump and the triple jump and will decide what event she competes in later in the year.
Race walker Isaac Beacroft will back up from the Glasgow Commonwealth Games at the U20 world titles.
"I've got pretty high expectations of myself in both races, and I don't want to leave that short amount of time in between each event as an excuse for my performances," he said.
Australia won a record 15 medals two years ago in Lima.
