The cricketer who quit the shortest version of the game in 2010-11, after the final match of the Ashes series, feels the team has the potential to win the trophy.
"I think we can win the Twenty20 World Cup," Clarke told reporters on Thursday.
"We've got the talent and we showed that in the last game against Pakistan in the UAE, and I think we've showed it in patches over the last couple of years."
Australia's defeat to Pakistan in the UAE, also ensured that Aussies were ranked ninth, while Ireland was also placed above the Aussies.
"It's different for the Australian team but I guess it shows we haven't performed as well as we need to in that form of the game," he added.
"We need to turn that around and what better time than at the World Cup."
Australia failed to win the Cup in 2010, as they played the final to lose to England in the Carribean. Now, with the fourth edition of the event starting on September 18, Clarke feels the team can definitely put up a good show as he has faith in the team led by George Bailey.
