I think South Africa will feel 15 runs short - especially after that fantastic start. A good partnership at the top of the order, it started so well, but then Kapp went for a second ball duck, Sune Luus provided a bit of resistance but they just don't turn the strike over enough for me.

I'm looking down the scorecard and Tazmin Brits is the only one with a strike rate over a hundred in their top five. You can't be expecting to striking competitive totals when you top order are scoring at less than a hundred.

A useful knock of 45 from 36 balls from Tazmin Brits laid the platform for South Africa, but it doesn't quite feel enough.

Australia pace bowler Darcie Brown:"It was nice to get her (Marizanne Kapp) early. I think the atmosphere made them feel like they were on top but we knew wickets would come.

"South Africa have some quality bowlers and it'll be tricky at the start but hopefully our batters get on top."

Thanks Aymen.

I think this will be a cakewalk for Australia - they have too much quality in that batting line up.

South Africa have a decent bowling attack, but it's going to take something special against Meg Lanning, Ellyse Perry, Tahlia McGrath and co.

However, Australia are without Alyssa Healy which could be a problem.

Will they be able to secure their place in the semi-finals? It's over to Timothy Abraham to take you through the rest.

It's a single to conclude South Africa's innings. They had a good partnership at the top of their batting order but after losing one wicket they started to crumble.

Surely it should be an easy chase for Australia.

Sinalo Jafta is off the mark with a single.

She wasn't going to be hit for the same shot two balls in a row. She pulled her length back ever so slightly, maybe took a bit of pace out of the delivery and it completely outfoxed Sune Luus who really had to go for it at this stage.

Ashleigh Gardner comes on to bowl the final over.

Where's that come from? She was prodding and poking around - she's had enough, she's frustrating herself out there. South Africa could really have done with that four or five overs ago.

There's a very big six from Nadine de Klerk! It was full from Megan Schutt and de Klerk hits a huge slog sweep over long-on. The boundary there is around 80 metres!

Georgia Wareham got two wickets in one over earlier too...

There's been incredible fielding by Australia.

Georgia Wareham is getting good turn on this wicket and the ball spins past the wicket. Beth Mooney doesn't take it cleanly otherwise there could have been a potential stumping of Nadine de Klerk.

Feels like the pitch is getting better to bat on. I feel like South Africa need to be up around the 140 mark and even then they might be below par.

Nadine de Klerk is the new batter and gets off the mark first ball.

Tucker struggled in that innings, seven from her 13, didn't find the boundaries or rotate the strike. And in the end a good yorker from Schutt sees the back of her.

Here's Ellyse Perry's breakthrough wicket earlier...

South Africa's dismissals have been very soft, especially Chloe Tryon. Australia's spinners are extremely strong in the middle period. The big question for them is who is in their best XI.
