Tuggeranong's Michaela Leonard will complete a rapid rise from rugby rookie to Test lock when she makes her Wallaroos debut on Saturday.
Leonard has been picked in the Wallaroos side for an international clash against Japan in Newcastle on the weekend.
The 24-year-old started playing rugby last year after being convinced to attend ACT Brumbies trials for the inaugural Super W season.
It has proved to be a genius move for the former basketballer, who has a chance to make her mark on international rugby against the 16th ranked Japanese side in a two-Test series.
The Wallaroos, ranked No. 7 in the world, are throwing new players into the mix before a trans-Tasman series against New Zealand and to test fresh faces before the World Cup in 2021.
While the world's top five ranked teams - New Zealand, England, Canada, France and the United States - are currently engaging in a tournament in San Diego, captain Hamilton was pleased some rising Australian talent will get a chance to showcase their wares.
Former Brumbies and Royals forward Millie Boyle will be a vice-captain after making her rugby league State of Origin debut last month.
Leonard is the only current Brumby in the Wallaroos squad after injuries prevented Shellie Milward and Tayla Stanford from earning Test call ups.
Meanwhile, Newcastle-born Wallaroo Alisha Hewett hopes more international fixtures are played in the region.
"I think it's an excellent idea," the 33-year-old said after training with the Wallaroos at Merewether on Thursday.
" grew up in a small little country town and I didn't know what rugby union was.
"To have a Test match against Japan is a great opportunity to inspire the young girls on the sideline."
