Wareham, who hails from Mortlake, will make her Ashes debut next month in England, having become a fixture of Australia's side since the lead in to last year's World Twenty20 success.

Aged just 20, Wareham is the youngest member of Australia's squad that landed in England last weekend before the opening one-dayer next Tuesday.

"I think she is going to be a key player over here," Mott said.

"She could be a real menace over here on these wickets and all our stats say that as well.

"It's exciting to be able to unleash her on England.

"Wareham has had a strong start to her international career, having taken 18 wickets at 19.72 across both short-form formats.

Playing men's bush cricket just five years ago, Wareham's game has developed to the point where she is feeling more comfortable in the Australian set up.

Figures show that of all bowlers who have taken 10 or more women's international wickets in England in the past decade, spinners have the three lowest averages in both one-day and Twenty20 cricket.

"(Georgia) turns the ball away and asks the question on both sides of the bat, which is what we really ask for," Mott said.

"In all three formats I think she asks real strong question of batters all the time.

"She just gets into her work, a pretty non-fussed cricketer and gets the job done."

Wareham has not played a Test match but is a chance of making her debut next month after fellow young tweaker Sophie Molineux was left out of the squad.

Australia retained the Ashes with a drawn series at home in 2017-18, after they jumped to an unassailable lead in the multi-formatted series, but they are desperate win outright this year.

Under the points system, two points are awarded for each of the three ODIs and T20s, and four points for the winner of the Test.

"Everyone in that team felt a bitter taste at the end of that series," Mott said of the previous Ashes battle.

"It really has been a motivating factor for the past 12 months ... In our minds one of the things has been unfinished business.

"We're happy to hold the Ashes but we want to come over and win."
