Wednesday evening's session in Dungannon marked the first time that the selected girls from both the regional squads (Belfast and Enniskillen) joined together to train as the new U-18 squad.
The sessions have been taken by Ulster Rugby Regional Development Officer Joy Sparkes and Schools Development Officer Nathan Moore, who both felt the need for these squads as a result of the significant number of U-18 girls playing in clubs around the province.
The excellent work done in the schools has provided a vital link in helping establish several new clubs in Ulster over the last few years.
It is hoped that this Munster-Ulster fixture will become a regular one - Sunday's clash has a 2.30pm kick-off and the Ulster side have already received support from Ulster prop Simon Best, who will captain Ireland on their upcoming summer tour to Argentina.
Best said: "Best wishes to the Ulster U-18 Development girls on this historic occasion. Munster will be a tough assignment but I'm sure you will do Ulster proud. Good Luck!!"
