Australia are not exactly the favourites at next month's ICC World T20 Championships given their past record.

But skipper Ricky Ponting feels it is hard to predict a team's chances in a format, which is perhaps the most unpredictable of all.

Australia were ousted by eventual champions India in the semifinals of the first edition of the championship and have won only 11 of the 21 Twenty20 internationals till date they have played.

"We'll be very well prepared"

But Ponting believes his side would put up a better show in the second edition of the event starting June 5 in England.

"I think that game is hard to judge if you try to get a form line even out of the IPL (Indian Premier League) there were all sorts of upsets throughout that," Ponting said. "It is that sort of game."

Ponting said his men have learnt their lessons from the last edition of the championship in South Africa and are expected to come up with a better show this year.

"We will be very well prepared for that, we have learnt a lot about the game in the last couple of years," he said.

"We were disappointed with the way we exited the tournament the last time around. You can expect a bold showing from Australia."
