Emboldened by Australia's remarkable turnaround in the ODI series against India, vice-captain Alex Carey said they are "really confident" of entering the ICC World Cup with a squad good enough to play like defending champions.

"As players in the Australian cricket side, we have been working hard for the last 12-18 months. Some success has started to come our way. We are really confident moving with the squad we take to the World Cup," Carey said on the eve of the series-deciding game here yesterday.
