A phenomenal display of batting from Beth Mooney and Alyssa Healy catapulted Australia to their fifth World Cup title, beating India at the Melbourne Cricket Ground on International Women's Day.

Opener Healy blasted 75 from just 39 balls including three successive sixes while Mooney's 78 off 54 balls helped the home side post 184-4 from their 20 overs.

India never really got going and when teen sensation Shafali Verma fell for two, the tone was set for an innings that never took off as the underdogs failed to reach three figures, losing by 85 runs after being bowled out for 99.

The stage was set by global superstar Katy Perry, who got the party started surrounded by dancers dressed as cricket bats in her first performance since announcing she was pregnant.

Having won the toss and opting to bat, Australia's openers set the tone from the outset with Healy smashing four off the first ball of the innings.

They showed no sign of slowing up and the ball continued to fly to all corners of the MCG before the Aussie opener and keeper fell to Radha Yadav having recorded the highest score by a batter in a T20 World Cup final.

If India thought this was their moment, they were sadly mistaken. 

Mooney continued the momentum, rocketing to an unbeaten 78 despite the best efforts of the Indian bowlers.

It needed to be quite some team talk from captain Harmanpreet Kaur if her team were to stand any chance of lifting the trophy.

With the expectations of a nation on her young shoulders, out walked 16-year-old super star Verma, top scorer in the tournament so far.

Thus far, Verma had showed so sign of nerves at the highest level, but a stellar piece of bowling from Megan Schutt, caught by the woman of the moment, Healy, meant the young star was quickly making the long walk back to the pavilion.

From there, the Indian batters failed to make any sort of recovery, with only Deepti Sharma showing any sign of resistance with her 33.

Wickets kept tumbling, along with the Indian hopes of their first title, and the game concluded as Poonam Yadav was caught by Ash Gardner off the bowling of Megan Schutt.

For Australia, who almost didn't reach the final in a rain-affected semi-final, the victory tasted even sweeter as captain Meg Lanning lifted the trophy.

It was an International Women's Day to remember for Australia, Healy and women's cricket worldwide.
