The West Indies have won the toss and elected to bowl first in the decisive fifth one-day international against Australia in St Lucia.

Australia have chosen the same team which lost Friday’s fourth match by 42 runs, leaving Nathan Lyon, Dan Christian, James Pattinson and Peter Nevill sidelined.

The hosts have also kept an unchanged team after their impressive win on Friday.

If the Windies can avoid defeat in the match they will win an ODI series against Australia for the first time in 17 years.

Australia captain Shane Watson said he was happy to be batting first, with conditions clear and sunny at the Beausejour Stadium.

“Really good, we were going to bat first anyway,” the allrounder said.

“The wicket looks really nice.”

The game begins at 9.30am (0030 Monday AEDT).

Australia: Shane Watson (capt), David Warner, Peter Forrest, George Bailey, Michael Hussey, David Hussey, Matthew Wade, Brett Lee, Clint McKay, Xavier Doherty, Ben Hilfenhaus. (12th man: Dan Christian)

West Indies: Johnson Charles, Adrian Barath, Marlon Samuels, Darren Bravo, Dwayne Bravo, Kieron Pollard, Andre Russell, Darren Sammy (capt), Carlton Baugh, Sunil Narine, Kemar Roach.
