PHOTOS: Aaron Finch's T20 record 156 off 63 balls

Record-breaking batsman Aaron Finch thinks a first win in any format in six months will give Australia a huge dose of much-needed confidence after the disappointment of the Ashes defeat.

The 26-year-old smashed 156 runs off 63 balls to help Australia beat England in a Twenty20 match at the Rose Bowl on Thursday.

The burly Australian struck 11 fours and 14 sixes off 63 balls to better the previous best of 123 scored by New Zealander Brendon McCullum.

The Australia with his knock gave a huge dose of confidence to his team.

"Luckily today was my day, any one of them could have gone straight up in the air," he said.

"It was just one of those days when everything hit the middle of the bat and things went my way," the 26-year-old said.

"It was a beautiful wicket. The outfield was lightning and all you had to do was hit the gap early and you got maximum value.

"It was a beautiful place to bat, I think the bowlers won't be too happy about it though."

In 70 minutes of batting fireworks, Finch hit 11 fours and a T20 record 14 sixes, one off the bowling of Stuart Broad bringing up his first international century from 47 balls.

The opener said he was unaware he had a chance to better South African Richard Levi's 45-ball record for the fastest T20 century.

"I think you saw, I started blocking the hell out of it around 100," he laughed. "I did get a little bit nervous but I had no idea what the record was."

Finch hoped his blistering innings would help him stake a "pretty good" claim to stay in the side for the second T20 against England in Durham and the one-day series to follow.

Although Australia's winless streak in test cricket is now guaranteed to extend to 11 months, Finch thought breaking the drought in all forms of the game augured well for the limited overs series against England.

"It's huge boost, there's a lot of new players in so there's a lot of fresh guys ready to go," he said.

"So I think there hasn't been a lot of baggage carried over from the Ashes ... I think everyone's really confident going into the series."
