Sydney (AFP) - An Australia team struggling for confidence and missing the wealth of experience that has long been the backbone of their success face a daunting task to win a first Champions Trophy title since 2009.

The World Cup holders are without their “Big Three” pacemen – Pat Cummins (ankle), Josh Hazlewood (hip) and Mitchell Starc, who has opted out for personal reasons.

It is a giant hole to fill with the trio sharing 525 ODI wickets across a combined 308 games.

Add in the absence of all-rounders Mitchell Marsh (back) and Marcus Stoinis (retired), and half of their regular team is missing.

Leg-spinner Adam Zampa is the only frontline bowler still standing for the tournament in Pakistan and Dubai.

The depleted side suffered a heavy 2-0 ODI series defeat last week in Sri Lanka, who failed to qualify for the Champions Trophy, and have now gone four 50-over games without a win.

Their death bowling is looming as a major concern.

The seamers Australia have selected – Spencer Johnson, Sean Abbott, Nathan Ellis, Ben Dwarshuis and all-rounder Aaron Hardie -– have just 52 ODIs in total, for a sum of 56 wickets.

Ahead of their opening Champions Trophy match against old rivals England on Saturday in Lahore, chief selector George Bailey is adamant they have enough ammunition to do the job.

“We have a range of options to shape the playing XI within the tournament depending on the opposition and conditions we face,” he said.

Drawn in Group B, they also face South Africa and Afghanistan.

Johnson will likely fill Starc’s new-ball strike role, tasked with making the early breakthroughs that have become a hallmark of the veteran quick.

“It’s obviously something I’ve pictured in my mind, to come in and play a similar role to him (Starc),” Johnson said.

“Hopefully I can replicate some of the stuff he’s done.”

- Opportunity -

Australia have twice lifted the Champions Trophy, in 2006 and 2009, and Steve Smith has been tasked with replicating the feat with regular skipper Cummins missing.

Travis Head, Glenn Maxwell and Josh Inglis join him in a potentially explosive batting order.

But Marnus Labuschagne is badly out of form and Australia are still struggling to fill the shoes of David Warner at the top of the order.

Jake Fraser-McGurk and Matt Short have so far been underwhelming, but one will be given another crack to open alongside Head.

Smith said the sobering Sri Lanka series was “another learning curve” while admitting Cummins, Hazlewood and Starc would “certainly be missed”.

“But it gives some guys an opportunity and I thought some of the guys who had an opportunity in the last two games (against Sri Lanka) bowled really nicely,” he said.

Despite his distinguished career Smith has never before played ODI cricket in Pakistan, and is unsure exactly what conditions they will encounter.

But he is confident the batters will rise to the occasion.

“The ball skids on probably a little bit more (in Pakistan),” he said. “So it’s potentially better for batting, but you’ve got to rock up and assess it and play to the conditions on the day.

“We’ve got a 15-man squad, quite a few batters in that squad we can choose from and we’ll pick whatever we feel is best for each scenario we face.”
