Skipper Alyssa Healy has been ruled out of Australia's key group clash against India in the Women's T20 World Cup with Tahila McGrath leading the team on Sunday.
Australia have won the toss and elected to bat in their last group match in Sharjah and a win will confirm their place in the semi-final.
Healy adds to Australia's injury list in Sharjah after fast bowler Tayla Vlaeminck was earlier ruled out of the rest of the tournament after she dislocated her shoulder in the previous win.
Healy retired hurt while batting against Pakistan because of an injury to her right foot.
Grace Harris and Darcie Brown have come into the team in place of Healy and Vlaeminck.
