This is professionals v amateurs, and the gulf is starting to tell.
England with their best phase of handling in this game so far, working it left to right before Packer darts through for her second try.
Scarratt's conversion strikes the inside of the post before flying over.

England not giving their opponents a moment's peace, Infante charging down a kick and getting her fingertips to the ball.
England 12-0 Australia
A key second try for England, giving themselves breathing room.
Given the awkward conditions and awkward opponents, they will be happy to just be doing enough.

Marlie Packer is absolutely thrilled with that try. The moment the ball was taken to the back, they were travelling at a rate of knots over the line.
That one counts!
England do what they do best, mauling their opponents into submission. Packer the one to place it down, ensuring all body parts are out the way of the ground.
No conversion, the kick just wide.
Marlie Packer has her arm under the ball. The England No 7 has held up her own try!
Unfortunate for England.
England 7-0 Australia
England work it out to their right and think they have a second try grounded, but Cogger-Orr is unsure.
We go to the TMO...
England 7-0 Australia
The Wallaroos captain is sent for 10 minutes in the bin for persistent fouling.
England will look to capitalise.
England 7-0 Australia
A second line-out not straight from Aussie hooker Talakai cedes possession yet again.
A game full of errors so far, the weather clearly affecting things.
England 7-0 Australia
Frustration for England as Abbie Ward fumbles the ball just five yards from the try line.
It feels a second England score is inevitable.
England 7-0 Australia
Such is England's strength in the maul, Scarratt kicks for a line-out from a penalty five yards out under the posts.
It turns into a maul as hoped, but Australia hold out just about. For now.

A try 'yes or no' call in a World Cup quarter-final should be checked out by the TMO.
That was tight.
England 7-0 Australia
England look as though they may have got a second try, but Sarah Bern is held just short of the line.
Referee Maggie Cogger-Orr blew for the score, but then admits she blew too soon. Scrum on the five for England.
England 7-0 Australia
Another smart chip puts Australia under pressure.
England are seeing out Aldcroft's sin-bin comfortably.
England 7-0 Australia
Despite the rain, there is not a lot of wind in Auckland today making this kick a decent option even from 40 yards or so.
However, Lori Cramer's effort falls short. Australia still to get on the board.
England 7-0 Australia
So, an unexpected hurdle for England to overcome.
They are then penalised for an offside, and Australia will kick for the posts.

That's a silly decision.
Why is the TMO calling that up? There will be another 150 rucks to review if you look at that.
Zoe Aldcroft found a six-inch void and managed to get her head through it. This could be three a side today.
Cogger-Orr disagrees with our expert, and shows the yellow card to the England No 4.
The Red Roses down to 14 for the next 10 minutes.

I am not sure what we're looking at here - that's just a very good clearout.
England 7-0 Australia
Referee Maggie Cogger-Orr is summoned to the TMO to check some possible foul play. Looks like there has been a contact of heads.
Zoe Aldcroft has gone in dangerously, it seems.
