Record four-time champions Australia beat South Africa by five runs via D-L method to reach their sixth successive Women's T20 World Cup final at Sydney on Thursday. They will meet India in the final in Melbourne on Sunday.
Australia skipper Meg Lanning led from the front with an unbeaten 49 off as many balls, taking the team to 134/5 in 20 overs.
Nadine de Klerk was the pick of the South Africa bowlers taking three wickets for 19 runs in three overs.
In response, South Africa ended at 92/5 chasing a revised target of 98 runs in 13 overs after rain returned during the innings break.
Brief scores: Australia 134/5 in 20 overs (Lanning 49 not out; de Klerk 3/19). South Africa 92/5 in 13 overs (Wolvaardt 41 not out; Schutt 2/17).
Earlier in the day, an unbeaten run in the group stage propelled India into their maiden Women's T20 World Cup final after their last-four clash against England was washed out, prompting both captains to say that reserve days are essential for knockout clashes.
Persistent rain since morning delayed the toss and eventually, the semifinal 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 semifinal match, curtailed to 13 overs after Australia's innings. The two teams 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 semifinals 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 semifinals," 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 had 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 had ended runners-up in the previous edition.
In the earlier seven editions, India had never reached the final but this time, they have emerged as 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.
