Redmayne – who completed a UNSW Bachelor of Medical Studies with Doctor of Medicine – joins emerging NSW and Sydney Thunder seamer Hannah Darlington as one of the two travelling reserves eligible for selection should any of the 15 squad members be affected by COVID or injury.

The World Cup squad leaves for New Zealand on February 10 and will complete a mandatory 10-day managed isolation period.

Redmayne graduated from UNSW in 2018 with Distinction, was a Ben Lexcen Scholar throughout her degree, named UNSW Female Athlete of the Year in 2017 and 2018, and earned the prestigious UNSW Sporting Blue.  

The 28-year-old wicketkeeper-batter is currently captaining Australia A against England A in a series of T20 and 50-over matches in Adelaide and Canberra, scoring an unbeaten 50 from 43 balls in the second of the three T20 matches.

Redmayne led Australia A to wins in each of the two completed T20 matches played at Adelaide's Karen Rolton Oval, with the other being washed out and three One Day games at Canberra’s Philip Oval to come.

For Queensland last season, Redmayne averaged an astounding 132.75 in the Women’s National Cricket League leading her adopted state to their first women’s 50-over title, highlighted by 134 not out in the Final against Victoria, complemented by two catches and two stumpings.

She finished the campaign with 531 runs from eight matches including two centuries.

With 437 WBBL runs at a strike rate of 120, Redmayne was also this season’s leading run-scorer for Brisbane Heat. She had the most dismissals by any wicketkeeper in the competition with 13 catches and four stumpings.

Prior to arriving at the Heat, Redmayne had played for the Hobart Hurricanes and Perth Scorchers.

Hailing from the Northern Rivers town of Alstonville in NSW, Redmayne relocated to Queensland in 2019, after playing much of her domestic cricket with Tasmania since 2015.

When she’s not playing cricket, Dr. Redmayne practices on the Tweed Coast, and has been on the frontline during the COVID-19 pandemic.

"(2020) I was working full time when the pandemic started here and it certainly changed the way we did things, having to get temperature screened every day, wearing a lot more PPE, implementing more protocols than normal and having restricted access to some parts of the hospital," Redmayne told the ABC's Brittany Carter in November.

The chance to play for the Welsh Fire in last year’s inaugural UK Hundred meant less time on the wards in 2021.

Australia’s One-Day World Cup campaign begins against defending champions England on Saturday 5 March in Hamilton.
