Although, India have a poor record against Australia, having lost 34 out of the 42 games the two teams have played against each other so far, the Indian women's cricket team seems confident as they have been playing good cricket in the tournament.
Australia beat India by eight wickets a week ago but is conscious of a side out for retribution and with the talent to cause an upset in Thursday's semi-final.
A win today will ensure India's entry into the summit clash against the host England at the Lord's, for the second time in the history of the tournament. She will have to concentrate on leg side as Aussies have in the last decade and a half purchased her wickets on off side.
One of the greatest ever innings in a world cup knockout encounter, Harmanpreet smashed her way to an unbeaten 171 off 115 deliveries with 20 fours and 5 sixes to her name.
One area where India will have an advantage is familiarity with the conditions, having played four games at Derby in the group stage, while Australia is yet to play on the ground.
"Once the players display something that they are not used to, it gives them a lot of confidence that even they are capable of", she added, reflecting on the "heartwarming" performance against New Zealand.
"I've really enjoyed it and it's nice to play on some wickets that have a little bit of turn".
Raj won't captain India in the next World Cup. Thanks to Harmanpreet's efforts, Mithali Raj's side were then 279 for 4 with a ball in their innings yet to be bowled.
India are the only side to have beaten England in this year's competition, winning by 35 runs on the opening day of the tournament.
India's Deepti Sharma celebrates with skipper Mithali Raj after claiming the wicket of Seda Nain Fatima Abidi of Pakistan during the ICC Women's World Cup match against Pakistan at the County Ground in Derby, England on on July 2. They will be up against the tournament favourites Australia. "It tempts me but I realise tomorrow is the game that can get us there, and it gets me back into now that we have Australia to play".
"She's working closely with the physios, the people that need to know (what Lanning's situation is) know what's going on", Australia allrounder Jess Jonassen said.
