Australia caught well in the outfield to reduce the Windies to 45-6, Ellyse Perry (2-2) removing the risky Deandra Dottin for just six.
"It's a completely different format, different team but the chance to be double world champions is very special".
Asked to chase 143 on a slow track at the Sir Vivian Richards Cricket Stadium, West Indies' batting woes returned to haunt them and they collapsed disappointingly for 71 in the 18th over - their joint second lowest score in the shortest format. "I think everybody can see the kind of favouritism that is being shown to certain members of the team", Annisha said.
That result was a massive disappointment for a huge home crowd but reinforced the consistent excellence of the top-ranked team in the women's T20 game who by that result went some way towards making amends for losing the final to the Caribbean side in Kolkata two-and-a-half years ago.
Australia men's skipper Aaron Finch, whose country will play as host to the two events in 2020, said: "It's exciting for Australia to be hosting both the ICC Women's T20 World Cup and the ICC Men's T20 World Cup in 2020". Six of Perry's wickets have come in finals, while Shrubsole took 6-46 in her last ICC final as England won last year's World Cup.
"It would be really special", she said.
Kaur's wicket soon after turned out to be the final nail in the coffin for India with the English players celebrating her dismissal by Gordon emphatically, knowing fully well that the scalp was worth its weight in gold. We've given ourselves the chance, I guess, but we need to make sure we get the job done tomorrow night. That's something that's pushed us forward I think.
Meg Lanning's Aussies also avenged their defeat to West Indies in the 2016 final, and can now prepare for their fifth consecutive WT20 final.
They will now await the winners of the other semi-final between England and India, to know their opponents in Saturday's final.
"It's probably the two best teams in the world historically over the last few years, and we've had some fantastic games of cricket recently", said Knight.
England will be happy that their batters had a good hit against India, but their bowlers have really punched above their weight.
"We won the toss and made a decision to bat but could not make it count". It's about holding our nerve and also showing that fight and grit that's been a really strong suit of ours.
"So for us to go out there and execute exactly what we wanted to do it's just really pleasing".More news: American John Chau killed by isolated Andaman tribe 'was a missionary'
