Ireland have already secured a spot in the knockout stages.
Aoife Wafer is not part of Ireland's squad for Sunday's final Rugby World Cup pool game against New Zealand, but co-captain Sam Monaghn has won her race to be fit.
Monaghan picked up a hip injury in last week's win over Spain, but she's been named to start in the pack, with co-captain Edel McMahon returning to the starting 15.
Offaly's Aoife Dalton will start her third game in a row, while Laois' Eimear Corri-Fallon and former Buccaneers player Anna McGann will both start on the bench.
Neve Jones, Ruth Campbell, Brittany Hogan, Aoibheann Reilly and Béibhinn Parsons also come in to start.
While Six Nations Player of the Championship Wafer is yet to feature at the World Cup, as he continues to recover from knee surgery.
Mullingar Rugby Coach Ray Murphy believes this is the biggest game in Ireland's history:
Kick off is at 2:45pm from Brighton on Sunday.
