New call-up Ben Hilfenhaus believes he can make a lasting impression for Australia, beyond the ICC World Twenty20 tournament.
The Tasmanian paceman, 24, was selected to replace injured fast bowler Shaun Tait in the World Cup holders' squad on Monday.
He has already proven himself on the domestic season, taking 60 wickets in the first-class season en route to winning the Ricky Ponting Medal as Tasmania's player of the year and the Bradman Young Cricketer of the Year award.
Having joined the squad on their latest quest for glory in South Africa, Hilfenhaus is eager to cement a permanent place in the national team.
"You've got to give the selectors a reason to keep you," Hilfenhaus said.
"It is just about doing the best you can and putting performances on the board."
His ability to swing the ball away from right-handers will offer added variety to Australia's attack.
But he is still striving to improve, and has spent the off-season working with national fast bowling coach Troy Cooley.
He added: "I spent most of last year at the centre of excellence with him and went up for a couple of weeks just recently and spent some time working on some technical things.
"He's been getting me to make little changes in the action for variety - he's fantastic on that score."
Australia take on Zimbabwe on September 12, before their clash with the old enemy, England, two days later.
