The reigning champions might not be the favourites to win the tournament this time, but eight ODI wins on the trot have provided a major boost to their confidence. Now with the return of David Warner and Steve Smith to the side, they are scrambling to get their combinations right. In the three warm-up matches against New Zealand XI in Brisbane, Australia used three different opening pairs and made several small changes to their line-up.
"I think it's just about giving everyone an opportunity at the top of the order to get some game time as much as anything," Finch said after the third unofficial game on Friday, 10 May. "I think it's a good opportunity to mix and match and with the three games in the UK we might keep everyone guessing a bit, but the honest answer is, no, we don't have a definitive answer on what that will look like at the moment. There are a lot of questions still to be answered but we are in a great place to do that."
The in-form skipper was also upbeat about Warner and Smith's return to the side. While Warner wasn't able to demonstrate his recent IPL form, Smith enjoyed his comeback with scores of 22, 89* and 91* in the three games.
"They are two of the best players in the world which is valuable to have at your disposal," the captain said. "The boys have been brilliant, all the work off the field with the team has been great. It's an interesting time, no doubt, when they are coming back in but still a great opportunity for everyone to learn off them as well. They have so much experience and what they bring to the group is really valuable."
I think it's a big advantage, just to know what it takes to win a World Cup and what it takes to manage your way through a campaign.
Finch also believes that their terrific performance in the last two months coupled with their World Cup-winning experience will be their biggest advantage going into the tournament.
"I think it's a big advantage, just to know what it takes to win a World Cup and what it takes to manage your way through a campaign which can be difficult. You have to be at your best at the business end but you can't afford to let anything slip at the start.
"Six guys who have been there and done that will give a lot of experience to the others of what to expect, what to feel walking out there because it is different," he further added.
Australia's World Cup title defence will begin on 1 June in Bristol against Afghanistan.
