Polosak has been chosen to officiate the JLT One-Day Cup clash between New South Wales and Cricket Australia XI at the Hurstville Oval in Sydney.

She will take to the field alongside Paul Wilson for the match.

Five-time International Cricket Council umpire of the year Simon Taufel informed Polosak that she would be an on-field umpire during the game.

Polosak has previously been a third umpire in a men's domestic contest and officiated four matches at the Women's World Cup in England earlier this year.

"I never played cricket, which is a little bit interesting for some people," she said.

"I always followed cricket, my parents got me into it and dad would drive me up from Goulburn to do the umpires course here.

"It took a few times to pass but it was something I was determined to do and I kept working through the grades in the Sydney competition."

The JLT One-Day Cup is the highest-level one-day tournament in Australian domestic cricket.

Australian international Mitchell Starc is among those expected to feature in the encounter between New South Wales and Cricket Australia XI, where Polosak will make history.

"There's preparation, there's playing conditions, learning the players, having a meeting with your teammate... discuss what signals you're going to be using, how you're going to communicate," Polosak added.

"Physically, it's very similar stuff to a player, fitness, core strength, back and legs because you're standing up on the field for seven hours.

"I've got mental triggers so I'm able to watch every ball as you go, so you can settle into that."
