Australia have named an unchanged XI for their World Cup clash against the West Indies at Trent Bridge.
West Indies captain Jason Holder won the toss and elected to bowl on Thursday morning.
Finch confirmed at the toss he will be leading the same team that comfortably defeated Afghanistan last Saturday in Bristol.
Paceman Nathan Coulter-Nile looked set to make way for veteran spinner Nathan Lyon if the Trent Bridge track was predicted to turn.
Windies duo Chris Gayle (back) and Andre Russell (knee) have been passed fit to play, and will take their parts in an XI with one change from the side that hammered Pakistan by seven wickets.
Hard-hitting batsman Evin Lewis comes in for left-hander Darren Bravo.
Following their bouncer barrage against Pakistan, the West Indies have suggested they'll employ a similar strategy against the Australians, who are looking for their 10th-straight ODI win.
But Finch says his side will be ready to handle whatever the Windies throw at them.
"(Bowling short) is obviously going to be a tactic of theirs and a plan," said Finch on match eve. "We will be as well prepared as we can be.
"We played them in a practice game down in Southampton and they bowled very similar. They had a lot of success with it last game and got off to a really good start, so I expect that they will come with a similar type plan.
"Over the last little while we have been aware that teams are going to use it a lot more and that is one of our plans, so we have been facing a lot of it in the nets as well.
"We're well and truly prepared, no doubt."
