Question marks over the fitness of fast bowler Shannon Gabriel and skipper Jason Holder were erased in pre-match workouts, allowing the West Indies to name the same team that thrashed South Africa by 100 runs two days earlier to qualify for the final.
On a pitch used for preliminary matches in the previous week, Australia have bolstered both elements of their bowling attack with pacer Nathan Coulter-Nile and wrist-spinner Adam Zampa replacing all-rounder James Faulkner and seamer Scott Boland from the side that got past the hosts in the World Cup-holders' final preliminary fixture six days earlier.
Teams:
West Indies - Jason Holder (captain), Johnson Charles, Andre Fletcher, Darren Bravo, Marlon Samuels, Denesh Ramdin (wicketkeeper), Kieron Pollard, Carlos Brathwaite, Sulieman Benn, Sunil Narine, Shannon Gabriel.
Australia - Steve Smith (captain), Aaron Finch, Usman Khawaja, George Bailey, Mitchell Marsh, Glenn Maxwell, Matthew Wade (wicketkeeper), Mitchell Starc, Nathan Coulter-Nile, Adam Zampa, Josh Hazlewood.
