AUSTRALIA'S women are desperate to start delivering in a format that has troubled them for the past few years.
This Ashes series still has an outright win up for grabs, but it's victory in the T20 format that holds extra importance beyond lifting the trophy on Tuesday night.
With the World T20 in the West Indies in a year's time before Australia hosts the next tournament in 2020, the Aussies are out to end a 27-month series-winning drought in the 20-over game.
Australia lost to the West Indies by eight wickets in the World T20 final last year, and they haven't won a series since August, 2015, when they defeated Ireland.
A win on Tuesday night at Manuka Oval will give Australia a 10-6 Ashes points win and the T20 series, and also a huge confidence booster for the long-term.
"It's a really great challenge," said Ellyse Perry, who was yesterday announced as a patron for the Sporting Chance Cancer Foundation.
"It's the last time the group is going to be together for quite a while.
"We go to Big Bash after this then come together later in the summer.
"From that point of view it's really important for our next step as a team, and our evolution heading towards the T20 World Cup in the Caribbean, to nail some things and (this game) is the best opportunity we've got."
Perry said consistency in the format was one of the team's main challenges.
But she knows if Australia are to host one of the biggest women's sports events in Australia with the World T20 in 2020, the players must start delivering now.
"We have an eye towards a home T20 in 2020 that we want to be the biggest competition that we've ever seen for women's cricket," she said.
"There's huge onus and emphasis on our team playing good cricket and being the best in the world at it.
"That's a hard thing to do in T20, to be consistent at it, but we have the ability in the group to do it, we just have to find the formula."
And though the players are thinking about what needs to be done long-term, they haven't forgotten there is a series to be won.
Australia failed to clinch the series win on Sunday when they fell 40 runs short of England's target of 153, a disappointing follow up to their six-wicket win at North Sydney on Friday.
Perry insists they are still playing for pride.
"I don't want to leave with the scoreline being 8-8,'' she said.
"I'd love it to be 10-6."
