England 56-4 Brazil
It feels like England have upped the intensity a couple of notches after conceding.
It could be a long 10 minutes for Brazil.
Amy Hardcastle, converted by Tara Stanley
Hat-trick for Amy Hardcastle!
A simple, powerful run by the pink-haired one, after a clever pass by Tara Jones to set her up. Hardcastle handed off her tackler easily and streaked off under the posts.
Tara Stanley is up to six conversions from 11.
'The try machine continues' - Hardcastle gets a hat-trick
England 50-4 Brazil
We get a shot of Georgia Roche in the stands.
She suffered an injury towards the end of last season, but we understand she has just been taken off as a precaution.

You give a gap to Tara Jones and she's going to take it.
Tara Jones, converted by Tara Stanley
England, stung, come right back at the Brazilian upstarts.
They pick apart their opponents and over goes Tara Jones by the posts. England's 10th try of the afternoon.
Tara Stanley brings up the half century with her fifth conversion.

BBC Sport at Headingley
A small section of the packed south stand at Headingley were up on their feet to celebrate that Natalia Momberg try. What a huge moment for the Brazil team, their first try in their first World Cup.
England 44-4 Brazil
England have made a couple of changes after the Brazil try, Grace Field and Georgia Roche coming off.
Saving their main players for the rest of the tournament.
England 44-4 Brazil
Talking of celebrations, pure elation from Grace Field as she crossed for one of England's seven first-half tries.
One of the pictures of the World Cup so far.

Sharon Shortle
BBC Sport commentator on BBC Two
They celebrate like they've won the cup! Well done Brazil.
Natalia Momberg
SCENES!
Brazil get a penalty after Caitlin Beevers goes in with a high tackle on sub Giovanna Barth, they make the most of it as Natalia Momberg goes over in the corner.
The celebrations from the Brazil players are wild and rightly so. A historic try, their first at the World Cup.
The conversion is wide, but it's all about those first points.
England 44-0 Brazil
Brazil are enjoying a bit more possession here, they're keeping the ball well and showing more patience.
They open up some space on the right wing, but Adriana Felix doesn't have the pace, power or belief to get it over the line.
England 44-0 Brazil
Leyther is right - Brazil have done nothing to disgrace themselves, they just can't compete with a team as experienced as England.
They will eye games against Canada and Papua New Guinea as much better opportunities for a maiden win.
#bbcrl
Leyther: Brazil aren't doing too badly considering they're a new team to international rugby league. Some of their defence has been great in the first half. A few more years with experience they will be up there. Keep it up England.
Amy Hardcastle
After the Leah Burke fumble, Brazil kick out from under the posts. However, it is a short, inaccurate kick and England are instantly back on the attack.
It works out to Amy Hardcastle on the left, and she charges over for her second try.
Tara Stanley drops it just wide, it was another tricky conversion.
England 40-0 Brazil
Brazil really look like a side which is playing only its third international ever. Rather naive in defence.
Here come England again, but the final pass out to Leah Burke on the left wing is looping and off target, it bounces off the wing's knee and out.
Burke got a boot to the face for her trouble too, and is patched up by the physios.
England 40-0 Brazil

St Helens and England half-back on BBC Two
England are just playing a bit more composed, they just need to get through those sets.
Fran did well to finish that because it was a bit of a funny bounce.
Fran Goldthorp, converted by Tara Stanley
England have realised Brazil really struggle with kicks through, and they take advantage here.
A slick grubber is fumbled by Amanda Welter and Fran Goldthorp nips in to score.
The conversion by Tara Stanley pushes England over the 40-point mark.
England's Goldthorp gets the first try of the second half
England 34-0 Brazil
Courtney Winfield-Hill is the main woman again, her dinked kick opening up the space behind Brazil.
Three England players converge on one yellow-clad defender, however the ball is knocked forward.
England 34-0 Brazil
Lois Forsell
Leeds Rhinos women's head coach on BBC Two
The overall message will be to do your job and relax a little bit.
With Brazil, they've come close. They just need to play in the right areas of the field.
England 34-0 Brazil
The second half commences with a kick by Patricia Oliveira.
How many more will England score?
