Historic! India in women's T20 WC final vs Australia

India had topped Group A with four victories in as many matches while England had finished second in Group B with three wins and a defeat.

India will take on four-time winners Australia, who defeated South Africa by five runs in what was also a rain-hit semi-final, curtailed to 13 overs after Australia's innings.

An unbeaten run in the group stage propelled India to their maiden women's T20 World Cup final against defending champions Australia after their semi-final match against England was washed out, in Sydney on Thursday, prompting both captains to say that reserve days are essential for the knock-outs.

Persistent rain since morning delayed the toss and eventually the semi-final was called off without a ball being bowled, taking Indians into the summit clash and leaving England players in tears.

India will take on four-time winners Australia, who defeated South Africa by five runs in what was also a rain-hit semi-final, curtailed to 13 overs after Australia's innings.

India and Australia will clash on Sunday, which also happens to be International Women's Day.

"Really frustrating. Not how we wanted the World Cup to finish for us. No reserve day, no chance of getting play, and ultimately that loss against South Africa cost us," a dejected England captain Heather Knight said after the game was abandoned.

Her India counterpart Harmanpreet Kaur also agreed that the semi-finals should have had a reserve day, a request which was made by host Cricket Australia but turned down by the ICC.

"Unfortunate we didn't get a game, but there are rules and we have to follow it. Having reserve days in the future will be a great idea," said Kaur.

Knight said her team paid the price for not starting the tournament well.

"It's all very English isn't it, talking about the weather and getting knocked out. It felt that we gained a bit of momentum in the last few games and we were pumped up for the semi-finals," she added.

"Lessons are to win the first game I guess (laughs). It's become a trend, not to start well in tournaments, and that has cost us."

India had topped Group A with four victories in as many matches while England finished second in Group B with three wins and a defeat.

"From day one, we knew we have to win all the games because in case the semis don't happen, that would be hard for us. In that sense, credit to the team for winning all the games," said Kaur.

"Everybody is looking in great touch. Shafali (Verma) and Smriti (Mandhana) -- they are giving us good starts, and that helps. Me and Smriti are trying to spend more time in the nets," she added, reflecting on her and Mandhana's so far indifferent form.

"We are looking more positive now. Unfortunately, we haven't come up with big innings, but our teammates are, and at the end of the day it's a team game."

England were runners-up in the previous edition.

In the earlier seven editions, India did not make it to the final but this time are serious title contenders after a string of superlative performances.  

They began with a win over defending champions Australia and went from strength to strength after that, beating Bangladesh, New Zealand and Sri Lanka to top Group A with eight points from four matches.
