We've already had the toss, which New Zealand won and opted to have a bat first.

Kane Williamson momentarily forgets his team but, after a nudge from Simon Doull, remembers that he's gone for Adam Milne, Tim Southee and Trent Boult as his seamers, with Luke Ronchi opening with Martin Guptill.

Birthday boy Steve Smith says Australia would have batted first anyway. James Pattinson is the pace bowler to miss out from Australia's big four-man attack. Mitchell Starc will play his first ODI since February.

Australia won by seven wickets in 2015 to claim the World Cup, with an unbeaten 56 from current captain Steve Smith - and 74 from then-captain Michael Clarke - guiding them to victory.

However, these sides have met each other plenty of times in the interim.

In the last six months they've played a series in Australia - which Australia won - and a series in New Zealand, which New Zealand won.

There's no home advantage this time, though. These two met at Edgbaston in the Champions Trophy in 2013 in a rain-affected game.

Hello! Welcome to today's coverage of Australia v New Zealand in Group A of the Champions Trophy.

It's a replay of the World Cup final, when Australia walked away the winners. But different conditions, a few new faces and a strong seam attack from both sides means we should be in for a cracker.
