Mason, an Otago girl who boards at Southland Girls' High School, is playing for the University side in the Dunedin women's rugby competition as well as her school this season.
A couple of years ago, Georgia, whose family farms south of Owaka at Chaslands in the very, very south of Otago, was picked in a South Island primary school side, beating hundreds of boys to make the team.
Last year, when just a year 9 pupil, she went to a South Island under-19 tournament, where she was named player of the tournament.
She played as a loose forward and joined Rugby Southland's academy, working on her skills along with promising male players.
She is now getting some expert coaching from Rugby Southland coaches but wants to take her game further.
After scoring 28 tries in eight games for the school's first XV last year, Georgia, along with her parents, decided to head for tougher competition. Now, despite her age, she is mixing it with the big girls in the Dunedin senior competition.
She usually plays half a game for the University side, which is tracking along nicely, having had just one loss this season.
With plenty of experience in the side, she is not finding the adjustment too hard, although she is helped by the likes of former Black Fern Anika Tiplady being in the team.
University coach Terry Kerr said Georgia had a natural feel for the game and seemed to pop up in just the right place.
She still had to physically grow to match it with some bigger and stronger players, especially in the forwards, he said.
Georgia turns 15 in August and has been deemed too young to trial for the New Zealand 2016 Olympics sevens squad.
Nor is she old enough to turn out for Otago in the national provincial championship.
Unfortunately, finances mean the South Island under-19 women's competition will not take place this year.
