Australia captain Alyssa Healy is a significant doubt for the remainder of the Ashes series after she was ruled out of the first T20I with a "stress response" in her foot on the same side as the injury she sustained at last year's T20 World CupIt meant that Australia were led by Tahlia McGrath in what became a convincing victory to retain the Ashes at the SCG while the top-order vacancy was filled by debutant Georgia Voll and Beth Mooney will keep wicket.

Alyssa Healy has been ruled out of tonight's opening Ashes T20I at the SCG and is in doubt for the remainder of the multi-format series after suffering foot soreness following Friday's third one-day international.

Alyssa Healy has a recurrence of the foot injury she picked up in the T20 World Cup and misses the opening T20 game with England.
