Halfback Teddy Wilson is following in his father David's footsteps after being named Junior Wallabies captain for 2023.
Wilson will lead the side in a two-match series against the New Zealand under-20 side next week before the squad heads to South Africa for the world championships.
Wilson's flanker father David captained Australia nine times, earning 79 caps between 1992 and 2000.
While David played for Queensland, 20-year-old Wilson made his debut for the NSW Waratahs last year, making six appearances off the bench.
He also went on the Australia A tour of Japan in 2022.
The youngster said he was surprised by the opportunity to lead the Junior Wallabies, who will face the Kiwis in Wellington next Monday before meeting in a second match there on Saturday June 3.
"It's a huge honour to captain the Junior Wallabies and it's something I will remember for a very long time," Wilson said.
"Getting asked to lead the team came as a bit of a surprise but I'm extremely grateful to Greysie (Nathan Grey) and the coaching staff for giving me this opportunity.
"As captain I want to lead by my actions both in training and in games, while also setting a positive example off the field.
"As a team we're fully focused on going to South Africa and winning the world championship."
The 12-team under-20 world championships run for three weeks starting June 24.
