Australia 127 for 2 (Mooney 61*, Gardner 35*) beat West Indies 125 for 7 (Matthews 30, Dottin 26*, Gardner 2-13, Wareham 2-17, Molineux 2-30) by eight wickets
Beth Mooney's unbeaten half-century led Australia into the T20 World Cup final after a miserly display by Australia's spinners outclassed West Indies in a dramatic first semi-final at The Oval.
Chasing just 126, Mooney's unbeaten 61 off 36 balls eased Australia to victory with a massive seven overs to spare. Ellyse Perry, the most in-form batter in the tournament, retired hurt with a quadricep issue.
Ashleigh Gardner put the squeeze on with 2 for 13 from four overs while legspinner Georgia Wareham and left-armer Sophie Molineux chimed in with two wickets apiece.
Mooney struck eight fours on her way to an eighth half-century at T20 World Cups, equalling Suzie Bates' record for the tournament. Gardner finished on 35 not out off 20.
