Australia secured their place in the World Cup final after a powerful century by Alyssa Healy and her dominant opening stand with Rachael Haynes set West Indies a target that proved well out of their reach.
The 157-run drubbing reflected each side’s path to the semi-finals, Australia unbeaten after starting the tournament as overwhelming favourites for the title and West Indies scraping into the top four on India’s last-ball heartbreak at the hands of South Africa in their final group-stage match.
Australia’s opening pair put on 216 runs – the highest partnership of the tournament so far – passing the 196 by Haynes and Meg Lanning for the second wicket against England, to post an imposing total of 305 for 3 from 45 overs after rain over Wellington’s Basin Reserve had delayed the start by an hour and 45 minutes.
Deandra Dottin and Hayley Matthews began the chase as aggressively as their hefty target required, but they both fell for 34.
By the time captain Stafanie Taylor dug in for a steadying but rather circumspect innings, it was too late.
Australia will play the winner of Thursday’s second semi-final between defending champions England and South Africa in the title decider.
Australia Women 305 for 3 (Healy 129, Haynes 85) beat West Indies Women 148 (Taylor 48, Jonassen 2-14) by 157 runs
