The Wallaroos have backed returning flyer Maya Stewart to make the difference in the quest to wrap up the series against Scotland on Saturday in Sydney.
Stewart is the lone change to the starting side that beat the Scots in Edinburgh, returning from an Achilles issue.
Her return moves Desiree Miller to fullback, with Caitlyn Halse ruled out under concussion protocols.
It's Miller's first Test start at fullback, after featuring there several times for the NSW Waratahs in their Super Rugby W three-peat campaign.
In the forwards, skipper Siokapesi Palu Sekona swaps jerseys with Pia Tapsell, shifting her to blindside flanker.
"We have maintained considerable selection consistency throughout the WXV, strategically strengthening our cohesion and combinations," Director of Women's High Performance Tim Walsh said.
"During the WXV, we have layered specific areas of our game to build stronger performances each test.
"We have selected a balanced 23 armed with leadership, power, strength and speed."
Walsh and the coaching staff have made several changes to the bench, mixing youth and experience.
Prop Eva Karpani is a huge inclusion as she looks to become the second Wallaroo to reach 50 Tests.
Karpani would crack the milestone in Canberra if named next week following Michaela Leonard’s milestone appearance in Scotland.
Allana Sikimeti has also recovered from a back injury and has been named to make an impact in the finishing unit.
Sevens star Piper Simons returns for her third appearance in gold, joining Cecilia Smith as the two back replacements.
The Wallaroos are out to stay undefeated against Scotland, with the match marking Scotland's first tour Down Under.
