An excellent display from the bowlers helped dismiss the Windies for 204 and a chanceless 107 not out from opener Nicole Bolton eased Australia home with 11.5 overs to spare.

Beth Mooney (70) and Bolton put on 171 for the opening wicket after three wickets from Ellyse Perry contributed to the 2013 finalists being dismissed with 13 balls remaining.

The match started in chaotic fashion at the toss when Windies skipper Stefanie Taylor called correctly and elected to bat.

However, midway through her pre-match interview with commentator Ian Bishop, she changed her mind, only for Australia captain Meg Lanning to object and insist on having the ICC rulebook being checked.

After much debate, match referee David Dukes adjudicated that Taylor's first call had to stand.

Emboldened by the no-nonsense approach from their captain, Australia were excellent in the field with Perry the pick of the bowlers, finishing with figures of 3-37.

Kristen Beams and Jess Jonassen also chipped in with two scalps apiece and two wickets fell to run outs.

The West Indies started steadily as they reached 4-157 only for their middle order to collapse.

Taylor (45), Hayley Matthews (41), Chedean Nation (39) and Deandra Dottin (29) were the only players to reach double figures.

In Australia's innings, Mooney departed for 70 after misjudging a full-length delivery from Taylor and Lanning (12) became her opposite number's second wicket when Matthews raced from long-off to take a superb catch. AAP
