Australia only batted for four overs but it was more than enough to again expose their fragile top order in the third T20I clash with England .

Friday's final match in Canberra ended in a no result washout, but left home captain Aaron Finch conceding his side had been outplayed in all three contests.

The visitors made 2-112 after being asked to bat first, before tearing through their foes with the ball in the rain-reduced, 12 overs-a-side match.

Finch's team will have been grateful for the rain, which spared Australia a series whitewash, with the match finally abandoned after a third weather delay.

At one stage, the Australians were reeling at 3-17 after English quick Chris Woakes (3-4) ripped the heart out of their batting card, dismissing Finch, Mitch Marsh and Glenn Maxwell in short order.

Finch holed out with the first ball of the innings and Marsh joined him in the sheds soon after when Woakes found a leading edge.

Makeshift opener Maxwell scored eight off nine balls before he too was caught.

It was the second straight game in which Australia's top order has offered little resistance in the run up to the T20 World Cup, having been left reeling at 2-22 against England on Wednesday after early exits for Finch and David Warner.

Maxwell's form remains a huge concern. He has made just 30 runs in his last seven T20 innings, but captain Finch said he wasn't even slightly worried about if he'd regain his X-factor form.

"Not one bit, he's an absolute match-winner," he told reporters.

"With guys like that who play a high-risk game, you have to ride the ups and downs at times and with the ball he's contributed really well.

"As an all-round package, he still contributed heavily to this team.

"With the bat he would like a lot more runs no doubt ... the reality is you can't expect somebody to play a high-risk game ... and be consistent.

"His numbers over a long period of time are remarkable."

Multiple delays meant the game was reduced to 12 overs each, with England captain Jos Buttler in imperious form blasting an unbeaten 65 that included eight boundaries.

He had help from Dawid Malan who crunched four boundaries in his 23, the duo adding 56 together.

After the second rain delay England sought to make the most of their limited overs, taking 30 off the first eight balls when play resumed.

Australia, who will face England again in the World Cup Super 12, will only play once more before the tournament begins, facing off against India in Brisbane on Monday.

Finch admitted it had been a concerning series for his side, given they were looking to find form before the defence of their World Cup crown.

"We were pretty disappointing in this series, England definitely outplayed us," he said.

"With the bat we were always just probably one wicket down further that we needed to be over the whole series.

"In big run chases you probably need that one 'in' batter towards the back of the innings, and we were just falling a little bit short each time with the ball."
