Jamaica make a change at the break. Havana Solaun replaces Tiffany Cameron.

Can Jamaica find a response? If not, they are heading home.

Australia are out of the changing rooms early and lining up in the tunnel. They have a quick team talk before the Jamaicans emerge.

Double trouble.

Sam Kerr's two headers in that first half.

Australia could still top Group C. They need to win by at least five goals to make up the goal difference on Italy and hope that Brazil nick a goal past them.

But if they don't score enough and Brazil win, they are back into third place!

David Church: Kerr proving how good she is again and again, surely got to be best player in the world this year.

Australia coach Ante Milicic at half-time: "Many of their situations come from us giving away the ball too cheaply.

"We're allowing the game to be too stretched than we would like. We have a good target and need to improve the quality of crossing."

Australia have never failed to go on and win a Women's World Cup game they have been two goals ahead in...

Jamaica coach Hue Menzies at half-time: "We've talked about it and went over it. We had our chances.

"Hopefully they''ll start listening because we have a good gameplan.

"We have to keep the ball and people have to move. Right now the players are keeping their heads down."

Australia are doing their job nicely. Brazil, who are still drawing 0-0 with Italy at half-time, have had chances but it's been pretty even.

Unless they can grab a winner, it's the Matildas who are facing Group A runners-up Norway in the last 16.

Sam Kerr 2-0 Jamaica. A comfortable game for Australia so far.

A hat-trick of headers then?

Khadija Shaw's cross is blocked by Karly Roestbakken and Jamaica win a corner.

It's aimed towards Shaw and she does brilliantly to reach it and fire a powerful header just inches past the left post!

Unsurprisingly, the effort sails over the bar but you have to applaud the audacity!

A rare chance for Jamaica to put a ball in the box as Khadija Shaw stands over a free-kick in the middle.

She looks like she's going to have a go from about 40 yards out though!

Jamaica 0-1 Australia

Khadija Shaw comes crashing into Ellie Carpenter on the right touchline and wipes her out.

She gets the ball though and the referee smartly keeps her cards in her pocket and just awards a free-kick.

Mireya Gray thinks she should win a free-kick in Australia's half but she bounces back up and chases down Lisa de Vanna.

The Australian, making her 150th appearance today, tries to cut onto her left but Gray reads it and slides in to make the tackle.

The story of the half so far. Jamaica are defending reasonably well but they need to get tighter to Sam Kerr on set-pieces and for open-play crosses.

Cheyna Matthews is the only player who has an average position over the halfway line.

Jamaica break with speed through Cheyna Matthews. She gets all the way into the box before losing her footing as she cuts inside onto her right foot.

The flag was up anyway though and the referee plays on as Australia can counter themselves.
