The toss was held after a delay of nearly three-and-a-half hours due to rain and the match has been reduced to 42 overs per side. In the end, a score of 282 from 42 overs proved to be a bit too much for Australia as they kept losing wickets at regular intervals, thanks to the precision of India's bowlers.

Earlier in the day, India named an unchanged XI from their win over New Zealand, while Australia brought in Meg Lanning for Rachel Haynes.
With the run rate rising and the pressure of a huge score on the board Australia suffered the most unusual of collapses and the match looked all but over.
Kaur had offers from three teams, but settled on Sydney Thunder because she felt more opportunities would come her way since the franchise had only one other overseas player.
