Wallaroos lose star but regain experience for historic 'quadruple header'

Maya Stewart returns for the Wallaroos on the wing to face Scotland in Sydney on Saturday.

ABC Sport will live blog the Wallaroos vs Scotland Test from 12pm, AEDT.

The Wallaroos have been forced to leave out star fullback Caitlyn Halse for Saturday's Test against Scotland at Sydney's Stadium Australia.

Halse is unavailable for the WXV Global Series Test due to concussion symptoms.

The 20-year-old's withdrawal is a blow but the Wallaroos have regained experienced winger Maya Stewart, who returns to the starting XV.

Stewart, a 27-Test veteran with the Wallaroos, was named after recovering from an Achilles tendon injury.

Her inclusion sees Desiree Miller move from the wing to fullback in place of Halse.

In the forward pack, captain Siokapesi Palu Sekona and Pia Tapsell swap positions in the back row, starting at blindside flanker and number eight respectively.

Eva Karpani and Cecilia Smith have returned to the match-day squad on the reserves bench, which also features fresh faces Allana Sikimeti and Piper Simons.

"We have maintained considerable selection consistency throughout the WXV, strategically strengthening our cohesion and combinations," Rugby Australia's director of women's high performance, Tim Walsh, said in a statement.

"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."

In their most recent Test, the Wallaroos triumphed 30–10 in Edinburgh late last month .

The two sides meet in Sydney and Canberra (October 23) to conclude their WXV Global Series campaigns.
