Sophie Spence - nominated for the World Rugby Women’s Player of the Year in 2015 - has been left on the bench with Mazzie Reilly and Paula Fitzpatrick named second-rows.

"They've had excellent preparation and things have really come together since arriving into UCD on Saturday afternoon. Everyone has been extremely focused on their role and the challenge ahead.
"The Australians are a good team and we will have to be very good for the opening game.
"The players are all very clear on the challenges that the Wallaroos pose.
"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."
Earlier today Australia head coach Paul Verrell named his starting 15.
Mahalia Murphy and Trilleen Pomare will make their Wallaroos debuts, lining up on the left wing and at out-half respectively.
The highly-rated Murphy is one of three Australia Sevens stars named to star, with Shannon Parry [above] captaining the side from openside flanker and Sharni Williams featuring inside breakout star Kayla Sauvao in the centre.
Liz Patu, Cheyenne Campbell and Hilisha Samoa will form a powerful all-Queensland front row, with Chloe Butler and Millie Boyle pairing up in the second row.
The 13-times capped Rebecca Clough and Ashleigh Hewson, who is the most-capped Wallarroo in the current squad with 15 Tests behind her, have to be content with places on the bench.
Mollie Gray makes her return to international rugby at blindside flanker alongside Parry and Grace Hamilton, who will start at number 8.
Katrina Barker and WA product Pomare form a new-look half-back combination, with Murphy, Nareta Masters and Samantha Treherne adding plenty of pace to the back-three.
