Former England bowler on BBC Radio 5 Sports ExtraThis outfield at Bristol is always quite fast and even with a bit of rain earlier today it doesn't get any slower. Phoebe Litchfield looks right at home.
Aus 39-1published at 7 overs
Phoebe Litchfield goes aerial again but a heave into the leg-side flies over mid-wicket before trundling over the boundary.
Australia are starting to build a bit of momentum here. Kate Cross has taken a wicket but has also gone for 28 from her first four overs.

How costly could this be? Sophie Ecclestone dropping Ellyse Perry when she was on just six.

Former Australia batter on BBC Test Match SpecialLauren Bell has got the short ball, we saw some good deliveries at Lord's, but we see here she doesn't have the pace to really trouble Ellyse Perry.
Aus 32-1published at 6 overs
Great placement from Ellyse Perry as she pulls a short delivery from off to on almost baseball style and the ball flies through a gap for four.
Australia are being ruthlessly efficient here, picking off the bad balls and dispatching them to the boundary.
Aus 27-1published at 5 overs
Another fine shot from Phoebe Litchfield, who latches onto a full ball from Kate Cross and plays and aerial drive that lands safely in the on-side and races away for four.
The Aussie left-hander has looked in fine touch so far.
Aus 22-1published at 4 overs
Plenty of swing and seam into the right-handed Ellyse Perry from the tall figure of Lauren Bell, who has gone for just six runs in her two overs so far. England will take that in the powerplay.
Kate Cross, who has been more expensive but a touch more threatening, will continue at the other end.

BBC Test Match Special commentatorWow, that would've been a huge wicket! Big drop, big moment.
Perry dropped on sixpublished at 2.5 overs
Australia close to being two down!
Ellyse Perry goes for an expansive drive outside off stump, a thick edge flies to Sophie Ecclestone at first slip but she cannot hold on!

That's a lovely shot from Phoebe Litchfield.
Lauren Bell comes around the wicket to the left-hander but bowls full and wide, with Litchfield clattering the ball through the covers for four.

Lauren Bell will open the bowling at the other end.
Aus 10-1published at 1 overs
There is a buzz around the ground now as Ellyse Perry comes to the crease and knocks two off her first ball before seeing out the final ball of the over.
Cross has a beaming smile on her face as she collects her cap from the umpire. She has got her team off to the perfect start.

That is a huge wicket. Alyssa Healy hasn't been in the best form this series but she can be so destructive.

Fair call from the umpire to not give that out because there was two noises there.
