That's all from us here today but you can catch TMS commentary of New Zealand v West Indies, which could be a crucial game in Group 2, starting at 18:30 from Southampton.

Make sure you read Matthew Henry's match report from Old Trafford if you missed any of this game and also Alvin McCaig's report from Scotland's win over Ireland earlier.

We'll be back tomorrow for a big game between Pakistan and India, which starts at 14:30 BST. See you then!

South Africa captain Laura Wolvaardt: "It was a tough day today. We had a pretty decent first half. Restricting them to that score was not bad but they bowled pretty well and out-bowled us."

On Australia's total: "I thought it was okay, a little bit above par but could've been worse. We backed ourselves to go at nine an over, but lost our way, struggled to get going."

On Ismail and Kapp: "It's awesome to have them back. It's been a long time since we had them bowling in the powerplay together. Our other bowlers stepping up today was nice."

On her batting: "It was hard to get going. A bit of a frustrating innings. I thought they bowled to me pretty well, shut down my best areas.

"It's still a long tournament to go. We'll put this game behind us as quicky as we can and focus on the rest of the tournament."

Australia captain Sophie Molineux: "We were in trouble at the start but the way the girls bounced back and climbed over it in our bowling innings, we are really pleased with it.

"We have a top and middle order that can play all round the park, and bat the best when they take it on. It's great to see them play with freedom."

On Phoebe Litchfield: "She is amazing, her game smarts right now are through the roof and I am so pleased to see her make a few."

On captaincy: "I get a lot of help! With captaincy, you have to go with your gut. It was spin-friendly, sometimes it pays off when you go like that and today was a very good day."

South Africa are in an in incredibly tough group.

We kind of knew that they wouldn't win today, but they aren't out of it. They've still got the other teams to beat.

Player of the match Georgia Wareham: "With our batting line-up, you know you can play with confidence and freedom. Phoebe was awesome and it was a good all-round performance by the team.

"We are versatile as a bowling line-up as well, we know we are good at keeping it tight and keeping it on the stumps.

"Soph's been awesome [as captain], instilling a lot of freedom in the group, making us believe we can take it on in the tournament."

Georgia Wareham deserved that [player of the match], she bowled fantastically well.

What I love about this Australian team is that they adapt so well. They are very honest in their communication to each other.

They are the team to beat. They've got so many all-rounders and they had a lot of things they could've done better today but still won by 65 runs.

Australia stuttered a bit with the bat - by their standards, at least - but an entertaining 50 from Phoebe Litchfield and cameos from Ellyse Perry, Georgia Wareham and Annabel Sutherland took them beyond 170.

With the ball, it was that formidable spin line-up. Kim Garth struck early but that was the only wicket to fall to pace as Alana King and Sophie Molineux took two each and player of the match Wareham finished with 3-13.

What a game to start. We always knew it would be a bit of a curtain raiser. Unfortunately for South Africa, it's another World Cup where they haven't got off to a good start.

South Africa were poor but Australia are just showing their dominance once again. 173 was always going to be a tough ask for them.

As dominant as you like.

South Africa are bowled out for 107 as Australia start their T20 World Cup campaign with a statement win.

You can understand what she was thinking. She was holding the strike, trying to face as many deliveries as possible. She tried to go up and over mid-wicket but clothed it.

It's all eyes on Chloe Tryon now. Is she going to try and stay out for as long as possible or will she try and get some quick runs?

Metronomic as ever from Gardner, just three runs and a wicket from it.

Can Chloe Tryon at least whack a few to boost South Africa's net run-rate?

Ismail has already taken her gloves off, she thinks she's out.

Another!

Well, Shabnim Ismail is given out lbw to Ash Gardner and reviews rather optimistically.

Alana King finishes with figures of 2-26.

That ball was hit quite sweetly by Jafta but too high and not quite long enough.

I respect the fact that she's come out swinging though.

Alana King deserves that.
