David Warner says he hasn’t changed any routines and only ‘maintained the rage’ to back himself and play his best cricket.
Warner, who looked clueless against Stuart Broad, scored only 95 runs in 10 innings in the Ashes.
The aggressive opening batsman has fired back with an impressive run in the Sri Lanka T20Is, accumulating 217 runs in three innings without being dismissed as Australia romped to a series whitewash.
Despite having a tough time against the Dukes ball in England, he insisted that he was always confident of getting back in runs.
"I've always been confident," he told reporters after an unbeaten 57 in the third T20 in Melbourne on Friday evening.
"I was out of runs (in England). For me, it's about going out there and trying to apply myself 100 percent, like I do every time. I've been hitting the ball as well as ever.
"I haven't changed any routines. "I've just maintained that rage to go out there and back myself and play to the best of my ability."
Limited overs skipper Aaron Finch said Warner getting back in the runs gives a lot of confidence to rest of the side.
"The confidence he gives to the group when he's playing well is huge," Finch said on Saturday.
"When he performs well, the team wins. That's a huge asset to have in your side.
"Especially for some of the inexperienced guys in the squad, it's a great learning curve for them to be able to have him and Steve (Smith) around."
While Sri Lanka looked out of sorts against Australia in the recent T20I series, Australia are likely to be tested a bit more by Pakistan, who are currently placed at the top of the T20I rankings.
Finch said they were not taking Pakistan lightly, even though the visitors were swept away by a second-string Sri Lanka side on their home ground.
That series costed Sarfaraz Ahmed his captaincy as well as a spot in the side.
"It's a (bowling) attack which doesn't give you much respite," Finch said of Pakistan.
"But they are going to give you scoring opportunities and you've got to chase them. It's a T20 at the end of the day and I think the first six overs will be very important in setting up the game."
