Australia captain Meg Lanning praised her team for coming through "tough times" to emphatically win the Women's T20 World Cup on home soil.

Alyssa Healy smashed 75 from 39 balls and opening partner Beth Mooney top-scored with an unbeaten 78 as Australia posted 184-4 in Melbourne, a total that proved well beyond India's reach as they were all out for 99 in reply.

However, while they triumphed by the huge margin of 85 runs in the final, it had not always been plain sailing for Lanning and her squad during the tournament.

They lost to India in their opening match in the group stage and, already without Tayla Vlaeminck due to a fractured foot, were dealt a further blow when Ellyse Perry suffered a hamstring injury against New Zealand.

The duo were still present for the victory over India on Sunday, taking part in the celebrations after Australia were crowned champions for a fifth time in front of a crowd of 86,174 - a new record for a women's cricket match and a female sporting event in Australia.

"I'm just really proud of this group of players and staff," Lanning said at the presentation ceremony.

"We've had everything thrown at us, ups and downs. It was tough, definitely, especially after we lost that first game. There was a lot of expectation on us, inside and out.

"There were definitely some tough times in there, but we stuck with each other, had each other's backs.

"Coming in they [the injured players] were a big part of our plans, we had to go to plan B and C.

"It's been massive, 86,000 people at the MCG, I've never seen it before and didn't think I'd be part of it in the middle."

India were left to rue missed opportunities in the field - Healy was dropped by Shafali Verma in the first over, while they also put down a chance off Mooney during a pivotal 115-run opening stand.

Skipper Harmanpreet Kaur hopes her players will learn from the experience after reaching the final of the T20 event for the first time.

"We need to focus, especially in fielding," she said. "But I trust this team. It's part of the game, sometimes you win and sometimes you lose. You have to keep learning. 

"If we talk about the last T20 World Cup, we got to the semi-finals, and this time to the final. I think we're on the right path.

"Every year we are improving. We just need to think of how we play with focus in the main games. Sometimes we don't manage that."
