Larissa Muldoon will partner outhalf Nora Stapleton at halfback, with Sene Naoupu and Jenny Murphy forming the centre partnership.
Head Coach Tom Tierney is confident the home advantage will help his side in the tournament opener.

“However this is a home World Cup and we’re confident that the crowd will get behind us tomorrow evening which will be an added benefit for us and we’re all looking forward to getting the tournament underway.”
