Richardson has been superb in the first four T20 internationals of the summer and will look to continue his form against Pakistan in Canberra on Tuesday.

The 28-year-old took 2-16 from three overs in the series opener on Sunday night, which followed his 2-63 at an economy of 5.72 in the three matches against Sri Lanka.

Richardson is tracking towards a spot in Australia's squad for the T20 World Cup next year but emphasised his focus was on this summer.

"T20 is that kind of game that can be quite fickle so you just kind of roll with it but it's nice to be contributing," Richardson said.

"I know a lot can change in a year. I learnt that in the 50-over World Cup just gone getting called up about two days before the team left.

"So for me it's just about trying to perform every single time I get an opportunity.

"I feel like I'm almost playing for a job going forward because there are so many good bowlers around, so I'd never look too far ahead."

Australian coach Justin Langer admitted he didn't believe Richardson would ever play international cricket again after a poor stint last year.

Yet Richardson said he'd changed little in his game over the past 12 months.

"Not really. Just developing some slower balls and trying to work on execution (because) as a fast bowler that's what you live and die on," he said.

"I'm always trying to get better and learn from guys who do that well. But I don't think I'm doing anything too mindblowing from what I used to do."
