Cameron White led Australia to 145 for four against England in the first Twenty20 international at Old Trafford in Manchester on Sunday.
White, dropped on 12 by debutant Joe Denly, made 55 and shared a fourth-wicket stand of 78 with Michael Clarke, Australia's captain in the absence of the resting Ricky Ponting.
The duo came together after England captain Paul Collingwood took two wickets in three balls to leave Australia struggling at 54 for three in the ninth over.
Victoria's White, who didn't feature in the Ashes series that England clinched 2-1 at the Oval last week, completed a maiden fifty at this level off 33 balls when he launched paceman Ryan Sidebottom for his third six.
He was eventually out when a lofted cover-drive off Ashes hero Stuart Broad was well caught by a leaping Collingwood in the penultimate over.
Clarke finished on 17 not out and Adam Voges was unbeaten on 11.
Collingwood - captain in the absence of Test skipper Andrew Strauss who has opted out of Twenty20 internationals - led from the front with his medium pace in the first meeting between England and Australia since the Ashes.
He took two wickets for 20 runs from his maximum four overs after winning the toss and making Australia bat in overcast conditions.
