I think it's a good call from Sri Lanka to bat first. They're going to try and make the most of this wicket. They'll be wanting to score a high amount of runs and put their team in a good position from the off.

Vishmi Gunaratne jabs Megan Schutt's first delivery into the on side and we're off.

Sri Lanka stumbled to just 85-9 when losing to Pakistan on Thursday, so they're really going to have to up their game against the best team in the world.

File this under "daunting prospect".

I can't believe Australia haven't picked Alana King; she is probably their spinner who can turn it the most. They've gone for one extra seamer instead. Australia have so many options though so they'll choose the team who is best for the day I suppose.

"Advance Australia fair" gets a nice airing and the players get ready to take the field proper in the 36 degree heat.

The teams are out and after the miniature fireworks die down, we have the national anthems. Sri Lanka are first, and as TMS commentator Dan Norcross has just said, it really is an "absolute banger"!

Alyssa Healy reflects on taking the field first, saying, "I’m not too unhappy to get out there as a group for our first game, so its not such a bad thing.

"We are well prepared and there is a real calmness around the group. We’ll have to adapt pretty quickly today, the girls are in real good nick, the breeze is nice and I think we’ll manage it well."

Sri Lanka skipper Chamari Athapaththu called 'heads' and that's how the coin came down - they will bat first.

"I’m pretty confident about my batting unit," says Athapaththu. "I know the heat will be important so I hope we can execute today. We have to execute plans at the right time, but we want to play positively. I’ve told them to play fearless cricket."

Good morning! We get our first sighting of the World Cup holders Australia in the first of today's two games as they take on Sri Lanka.

Can they throw a spanner in the works and disrupt the Australian juggernaut? We'll find out soon, but first here's news of the toss.
