I can't quite believe what I'm saying - the crowd that has turned up, the Katy Perry concert and the start Australia have got off to. This is a massive sporting event.

The economical Gayakwad, with 0-7 from two overs, is kept on for a third. The crowd are having a chance to get their breath back after that Katy Perry set, and Healy's opening blitz - the Aussie keeper does take the aerial route, but it sails safely over mid-off for two.

Australia are wary of Poonam's leg-spin, as well they might be. Five carefully-taken singles from her first over.

Mooney rocks onto the back foot and steers Poonam's first ball for a single. That's the fifty stand.

Here's how Beth Mooney got her innings going.

It's a good decision to get Poonam Yadav into the bowling attack now; to try and get a couple of wickets and slow down Australia a little bit.

Time for Poonam Yadav - one of the best, shortest, slowest, loopiest, leg-spinners in the business.

India haven't played since last Saturday - and it shows. Two dropped catches in the first five overs and some absolutely brutal thumping from Alyssa Healy has swung things firmly in Australia's favour.

Healy moves to 30 off 20 balls with a single, and India escape without further damage in the powerplay as Mooney rounds it off with a single. Just two from Gayakwad's over.

Alyssa Healy is going to want to keep using her feet and targeting the off side.

Healy has a grin on her face as Gayakwad spins one past her outside edge. The left-arm spinner starts the over well with three dot balls.

This wicket is playing so well - other pitches have been low and slow, but the bounce is there today and the ball is coming onto the bat nicely.

Tighter from Pandey, but Mooney delicately jabs a four past the fielder at short third man - while she punishes any width outside off stump with another four through the covers.

Plenty of Australian children dancing in the crowd, as well they might, while Pandey holds her head.

Healy has also passed 2,000 career T20 international runs today.

Shikha Pandey has changed ends, but the fielders are having to shuffle around a lot with the left-hand/right-hand combo in action.

The torrent of runs has been slowed ever so slightly in the last couple of overs.

And the first of those dropped catches...

Here's the opening number from the Alyssa Healy Show...

The reprieved Mooney adds a single. Decent over from Gayakwad, only five runs from it, but there could have been one in the "W" column.

How costly are these half chances - you tend to only get three or four in an entire game.
