Young batsman Mark Cosgrove is a certainty to make his one-day debut on Friday as the exhausted Australian cricket side completes its taxing schedule in a dead rubber in Bangladesh.

The 21-year-old's elevation will mark a speedy return to grace for the chunky batsman who was suspended from the South Australian side for being too fat.

The Australian team was yet to be named for the third and final match of the one-day series against Bangladesh at Fatullah Stadium after the tourists wrapped up the series with a 67-run win.

However Australian captain Ricky Ponting strongly suggested the trio of Cosgrove and fellow World Cup aspirants Brett Dorey and James Hopes would play in the final clash.

They are the only members of the 14-man limited-overs squad not to have played in Bangladesh after the world No.1 side opted for the same lineup in both Chittagong and Dhaka.

"It has been well spoken about that we have been up for a long time now and played a lot of cricket," said Ponting.

"I actually said to the guys coming into this series that we would try and give all the players if we could at least one game, and hopefully two.

"But that has not been the way it has worked out.

"We kept the same side for the first two games but now we do have the opportunity to look at Brett Dorey and Cosgrove and Hopes.

It is a key opportunity for all three players to press for a berth in next year's World Cup squad.

Cosgrove was named ING Cup player of the season for his exploits last summer after responding to his month-long suspension by scoring 736 runs at 66.9 in the Pura Cup and 591 at 73.9 in the ING Cup.

With Damien Martyn to return from an elbow injury, any runs will aid Cosgrove's case to tour the Windies as Australia chases an unprecedented third straight World Cup.

Dorey had an ordinary start to his one-day career in three matches during the home tri-series following some strong form for Western Australia at domestic level.

He has only claimed one wicket at 134 at an economy rate of 5.82 and must grab the opportunity to keep his name in the queue.

It is a similar situation for Hopes who only came into the squad because of an injury to fellow Queensland all-rounder Shane Watson.

The 27-year-old has not managed to make much of an impression in his first eight one-day internationals having not scored a half century or claimed more than one wicket in an innings.

Mike Hussey said the players were knackered but trying to lift for one last effort to finish off a testing tour of Bangladesh with a clean sweep in both forms of the game.

"It has been a great summer considering how hard the boys did it in England and so I think it would be great for us to just go out and give one last effort for Australia and finish on a high," he said.

The Bangladesh side was yet to be named.

Team:

Australia (likely): Adam Gilchrist, Simon Katich, Ricky Ponting (c), Michael Clarke, Mark Cosgrove, Michael Hussey, Brad Hogg, Nathan Bracken, Mitchell Johnson, Dan Cullen, Brett Dorey.
