England will head into this week's day-night Ashes Test underprepared against the pink ball following an unsatisfactory tour match at Blacktown last week.
The visitors trained under lights on Wednesday night in a last-ditch bid to adapt to the conditions expected at North Sydney Oval, and must now take on an Australian pace attack brimming with confidence after they enjoyed timely pink-ball success in Canberra last week.
While the Australians had a productive three-day warm-up match against an ACT XI last week, England took on a young Cricket Australia side at Blacktown in a contest that produced very little of the swing Australia's Megan Schutt and Lauren Cheatle should produce under lights at North Sydney Oval.
"We played at Blacktown, which probably resembles nothing like you are going to play on," England coach Mark Robinson said.
"It [the wicket] took chunks out of the ball so playing under the lights was irrelevant, really, because you had big chunks out of the ball so it was never going to swing.
"We are practising under lights tonight [Wednesday] and we'll probably have a better context to what it will do there.
"In any game of four-day cricket there will be stages when it will become difficult to bat, the wicket can change as the game goes on. The skill of the batters will be to adapt.
"There has been a lot of talk about in that twilight period the ball doing a bit more and it remains to be seen whether it will over these next four days. The wicket is quite dry, actually.
"We back the skills of our batters and then our bowlers to adapt to the circumstances as needed."
Just how England line up on Thursday remains to be seen. Their squad boasts plenty of spin-bowling firepower, but wickets at North Sydney Oval are likely to be harvested from quicker bowling, under lights and with the unpredictable pink ball.
Robinson won't announce his team until the toss on Thursday.
"We have four world-class spinners in our squad," Robinson said.
"I feel there is a potential to play three spinners but it will be how we complement the seam and if we play an extra batter.
"So, we are confident we have a squad to pick 11 from to win us this Test match."
Captain Heather Knight was bracing for an aggressive approach from Australia.
"They are going to come at us hard, no doubt about it," Knight said.
"That's the way Australian teams generally play. For us, it is about nullifying that and quietening them down and playing our way and standing up to them face to face and trying to throw a few punches back.
"It is about reading the situation and being smart. It's something we've improved a lot on over the last couple of years, being a lot smarter as cricketers and knowing when to attack and when to be a bit smarter to sit in so you can attack later."
