Having played the lower ranked sides during the opening rounds, both nations started the tournament strong but have dipped in more recent matches with both registering their first losses in their most recent matches.
The Mithali Raj-led side were on a winning streak beating England, West Indies, Pakistan and Sri Lanka before South Africa gave them a 115-run thumping defeat. The Aussies lost to England by just three runs, while India were defeated by a huge margin.
The right-hander scored two of those fifties against Australia early past year, an effort she knows she'll likely need to replicate if she wants to upset the tournament favourites and seal India's place in the semi-finals.
England, Australia and India share eight points each in the table to remain first, second and third respectively, divided by superior run-rate.
The last match witnessed an abject batting surrender by India as they got out for a meagre 158 while chasing 274. After all, the last time India and Australia came face to face, Raj helped the team pick up a five-wicket win.
Raj wants her team to play "fearless" cricket. Similarly Australia's four-match unbeaten run was stopped by England in the previous game and they would also look to get back to winning ways.
"We probably didn't play as consistently as we would have liked [against England]", Lanning said. "Even before the World Cup started, we said that we were going to do our best and not have to depend on other teams", she added.
Australia: Meg Lanning (captain), Sarah Aley, Kristen Beams, Nicole Bolton, Alex Blackwell, Ashleigh Gardner, Rachael Haynes, Alyssa Healy, Jess Jonassen, Beth Mooney, Ellyse Perry, Megan Schutt, Belinda Vakarewa, Elyse Villani and Amanda-Jade Wellington.
