Australia has a 2-0 series lead.
There is a scorecard.
Australia defeated England in the opening match of the Women's Ashes, thanks to a brilliant all-round performance by Tahlia McGrath.
Australia chased down 170 with 18 balls to spare at the Adelaide Oval, thanks in part to an impressive batting performance by McGrath.
She and captain Meg Lanning shared a brutal 144-run stand to help Australia register their highest chase in T20s.
England had posted 169-4 from their 20 overs.
England's ragged bowling and fielding display cost them the game.
Australia has two points in the multi-format series, with the second of three T20s taking place on Saturday.
No problem for Australia.
In the space of three deliveries, the bat and ball of Tahlia McGrath was used to take down Danni Wyatt and NatSciver.
It shows how much depth Australia has after they dropped Ellyse Perry, an icon of Australian cricket.
While Perry has struggled for consistency in T20s in recent times, McGrath excelled in Australia's series against India and offers more power with the bat.
She hit 13 fours and one six and put the pressure on England's fielders.
With Lanning opening in place of the injured Beth Mooney, and chipping away at the run-rate, McGrath had licence to hit out.
She stepped forward and drove strongly as Glenn's three overs disappeared for 39.
NatSciver and Freya Davies were both expensive, with NatSciver pulling Davies handsomely into the stands for her sole six, and onlySophie Ecclestone came close to finding the control England's bowlers needed.
When Heather Knight brought herself on to bowl at the end of the chase, McGrath hit three fours in three balls, showing Australia's dominance in what could have been a tricky chase.
She had earlier impressed with the ball, including dismissing the set batters in the space of three balls to check England's progress.
As the series progresses, her pace and accuracy will bode well for Australia.
England failed to make most of their batting.
England's preparation for the series was "comical", with players' families feeding a bowling machine as they spent Christmas in near-isolation.
The fielding was more disrupted than the batting. Australia was helped on their way by a number of misfields.
They were sloppy with the ball, giving up seven wides and one leg-bye, as the disciplined lines and lengths of the first few overs disappeared.
They would have felt like they had a chance at the halfway point. They were rusty with the bat at the start, but they had an excellent platform to build on.
The two shared an 81-run stand to put the hosts under pressure.
After striking her first two deliveries down the ground for six, Wyatt was particularly impressive, attacking key bowler Jess Jonassen straight away by striking her first two deliveries down the ground for six.
The 59-run stand withSciver looked to have put England within touching distance of 180, but the return of the attack limited them to 169.
It was not competitive enough against Australia's white-ball team.
They said that England didn't bowl well enough.
Heather Knight said that the way Danni Wyatt and Tammy Beaumont came out and batted was outstanding.
We thought we got to about par with the bat. They made it difficult to set fields. We have to learn from that.
England World Cup winner Alex Hartley said on the Test Match Special that they looked a bowler short because they didn't bowl well enough.
They had enough runs on the board, but they didn't bowl well enough.
"I'm just loving playing cricket at the moment, I'm an all-rounder for Australia." It's nice when you're winning. I will roll with it as long as possible.
We thought it was about par. They had a good start and we pegged it back. We gave ourselves every chance.
