Georgia Elwiss is determined to mark her international return by helping England make a "special" comeback of their own when they face Australia in this week's Test with the Women's Ashes on the line.

Elwiss, the 28-year-old allrounder who has played the past two WBBL seasons with Melbourne Stars, was named in England's 13-strong squad for the four-day match starting at Taunton on Thursday after being sidelined for more than four months with a back injury.

"Injuries are never nice and I think it's just made me really hungry to be able to contribute to hopefully us pulling off something special for the rest of this series and regaining the Ashes," Elwiss said.

England trail Australia six points to nil after losing all three of their ODIs and must win the Test, worth four points, to remain in the contest for the Ashes with three T20s worth two points each to follow.

Elwiss admitted it had been difficult having to watch her team rather than taking part after she felt pain while playing England's one-day series in India in February and scans revealed a small stress fracture in her back, which then ruled her out of the tour of Sri Lanka, plus a home series against West Indies.

"Unfortunately I had to get shut down for a fair few months, so I'm on the comeback trail now and fit and raring to go," Elwiss said. "Hopefully I can contribute to the girls this week and bring some energy and bring something new to the dynamics of the team.

"It's been not very nice watching the girls out there playing while I'm stuck in the gym but I think that' s made me really hungry to do everything really well and properly and diligently and so I know that now I'm back I'll be back better than ever."

Elwiss has played two Tests, in the 2015 and 2017 Ashes, batting at No.4 in the latter where she made a second-innings 41 not out off 190 balls to help England hold out for a draw after Australia's Ellyse Perry had notched an unbeaten double century.

Elwiss struck an unbeaten 44 batting at No.4 and 36 opening for England in a three-day tour match against Australia A, which finished on Sunday, and said while she enjoyed batting in the upper middle order, she was feeling good with bat and ball and was happy to do "whatever job is asked of me".

"I've got to break into the XI first and then see where we go from there," Elwiss said. "The ODI series was disappointing. We need to remember that we're not a bad team and we're not actually that far away from the Australians.

"They've played some good cricket, probably by their admission not the complete package in terms of their ODI game either. We've played some good cricket at times and I think we need to keep remembering that they're humans as well and they're going to make mistakes and we're ready to pounce."

Elwiss comes into the England squad alongside youngster Kirstie Gordon and Katherine Brunt, the 34-year-old fast bowler who is a veteran of 11 Test matches. Brunt, who is no stranger to back injuries with disc problems that require ongoing management, returns having missed the third ODI against Australia after hurting her ankle while leaping in the air to celebrate taking a wicket in the second match of the series.

"We call her the grandma of the group - she hates it," Elwiss said. "She's got all the experience but she's still got the heart and the drive and the fight of a 19-year-old coming in and that's testament to her.

"She's played a lot of Test matches and a lot of Ashes Test matches. She's been through a lot in her career and has got plenty of battle scars and things like that so she's a great person to have around the group. She's great for giving advice.

"She does waffle on a lot so you have to pick your moments to get advice from her because you could be sat there for half an hour listening to her answer, but she's great," Elwiss added with a laugh. "She's a great person to have around and she's great with the youngsters because she's always willing to offer that advice."
