Austrailan Delissa Kimmince has been ruled out of the three Twenty20 Internationals that conclude the Women's Ashes due to a back injury.
She has been struggling with a lower back injury and will not travel to England as a result.
Queensland all-rounder Grace Harris will replace Kimmince in the squad and join up with the squad on Friday.
She will head to Ireland, where Australia play three warm-up Twenty20s before the first of the three T20Is against England on 26th August.
"Delissa has been experiencing pain in her lower back, which is currently being investigated." physiotherapist Megan Roy said.
"As a result she has been ruled unfit to travel to the UK for the tour. She will remain in Brisbane and continue to receive appropriate medical treatment."
As well as Harris' imminent arrival, Beth Mooney will also join up with the squad as cover.
She is already in England having been playing for Yorkshire this summer and trained with the squad in the build-up to the Ashes Test.
Australia lead the multi-format Ashes series 4-2 with the Test match underway in Canterbury.
