Tausala Samu made Mortimer Shield history after becoming the first girl to take out the Rick Keast Medal.
Taking on the boys, Samu played a big role as Griffith Public School stormed to victory in the final at Parramore Park on Tuesday.
They proved far too strong for St Marys Young, taking a 18-0 win, with Samu earning the nod as the team's best.
In just her first year of rugby league after moving from Samoa, team manager Angela Catanzariti thought her strong defensive efforts really caught the eye.
"She just backed up her hard tackles," Catanzariti said.
Fisita Tuaiaki and Haka Barrett also put in strong performances.
Catanzariti was impressed by how the team came together on the big day.
"They had a great day and really wiped the park with their opponents," she said.
With the rise of leaguetag, NRL development officer Adam Perry said it is rare to see girls taking on the boys in the competition.
"Each year there is a handful scattered across the different teams but because of the popularity and strength of the leaguetag competitions most girls play in that but she was very good," Perry said.
"She was nice and physical and fast."
Meanwhile South Wagga Public School took out the leaguetag with a 16-0 win over Sturt.
They had showed plenty of scoring prowess to make it through to the final, and didn't stop there was another impressive display.
Speedster Holly Williams named as the Rick Keast Medal winner.
