But Campion took control with some good attacking play.
Sisters Breanna and Summer Ferris played well together for the students, while Marist Thistle midfielders Kirsty Moiser and Alecia Ulu had their hands full coping with fast opponents.
Lucy Allan and Sofia Zame scored hat-tricks for Campion, while Grace Levy and Dara Mulrooney scored two goals each.
Marist Thistle had some attacking opportunities in the second half, but the Campion defence — with Jasmine Sparks outstanding — kept them at bay.
Injury problems meant Marist Thistle finished the game with only 10 players on the field.
