McGrath, 24, is a newcomer this year after an impressive 2019-20 campaign, which saw her win the Andrea McCauley Medal for the second consecutive year, at SACA's online Dansie McCauley Medal Night.
McGrath played all 16 games in the Strikers' impressive rebel WBBL|05 season, as she continues her development as an integral allrounder for the team.
Women’s National Selector Shawn Flegler said: “Tahlia McGrath had a brilliant season with the Adelaide Strikers and South Australia, winning the Andrea McCauley medal. She’s been a consistent performer over the last few seasons with bat and ball, including the five matches she played for Australia during the 2017 Ashes series.
“With Tayla and Ellyse Perry coming back from long-term injuries, Tahlia will add extra depth to our all-rounders, especially with her bowling. We saw that depth come into play during the recent World Cup and we know that will be important with another World Cup scheduled this summer."
Schutt remains on the list after playing her role in the women's T20 World Cup triumph against India at the MCG, and she continues to lead the Strikers' bowling attack with aplomb.
Strikers captain Head enjoyed a strong second season in the baggy green, most notably saving the second Ashes Test at Lord’s along with a Boxing Day century against New Zealand.
Wicketkeeper-batsman Carey has also become Australia's first choice gloveman in the short formats, particularly due to a breakout World Cup campaign which saw him named in the ICC Team of the Tournament.
