Up to 25mm of rain is forecast to soak Canberra on Saturday which threatens the women's decider, along with semi-finals of the men's Douglas Cup. If Phillip Oval is rendered unplayable on Saturday, the two teams will return on Saturday, March 27 to contest the decider.

No such reserve day is possible in the men's competition, with next weekend scheduled for the decider.

Reigning premier Western District hosts Tuggeranong at ANU South in the first semi-final, while Weston Creek/Molonglo takes on Eastlake. In the event of a washout, the highest-placed teams will progress to the grand final.

The rain has continued a horrible run of recent luck for Cricket ACT in finals, after both of last season's deciders weren't played due to the COVID-19 pandemic.

Ginninderra is desperate to take the field, after qualifying for its first women's grand final just four seasons after establishing its Lynne O'Meara Cup side.

"We're the first women's side to actually make the grand final so it's a massive achievement for our group we're just really excited," Ginninderra co-captain Mary Walters said.

"We've really started to build a lot over the season this would kind of be the best thing to happen for our club just to help develop our female program.

"The club started up female cricket about four years ago so it would be really good for our group if we were able to win it but we'll see how we go on the weekend."

The two teams have developed a rivalry over the competition, with plenty of banter being sent back and forth already this week.

"We've got a couple of juniors who have come up and really stepped up and done really well few girls from Wagga as well have come and joined the team and they've been amazing," Ginninderra co-captain Caitlin Galeano said.

"Charlotte Waring has been quite impressive and Perri Nash as well with her leg spinners when she gets them right they're pretty good."

Creek captain Kelly Rowling said her side was determined to play regardless of the weather.

"A lot of us train together with the development squad and the Aces, we are familiar with each other's strengths and weaknesses so we'll try and get one over each other on the day," Rowling said

"It's our game to lose definitely but we're ready and prepared for every situation and I'm confident that we've got the skills."
