Ireland look to get the maul rolling from close range, but the green machine is brought down narrowly short of the promised land.

Another penalty. Aussie discipline is evaporating...

Again the visitors go for the line-out.

It's Adam Coleman that's been pulled up.

What happened beneath that mound of bodies? Conor Murray shoves a gold shirt away.

But as things settle down, it's just a penalty for the visitors and Sexton sticks it into touch.

Having shown their frustration at the decision to sin-bin Israel Folau in the first half, this Sydney crowd are now cranking up the volume once more and urging the Wallabies forward.

But it's Ireland flooding forward, a deep kick from Johnny Sexton bobbling and bouncing into the path of Keith Earls as the winger darts towards the line.

He can't gather... but chance for an early penalty?

Back under way at the Allianz Stadium.

Big 40 minutes for Ireland...

Love it... keep them coming.

Two sin-bins, plenty of penalties... this series decided is shaping up to be an edgy affair.

Ireland lost Jacob Stockdale for 10 minutes in the first half, while Australia were down to 14 men after Israel Folau was sent to the bin.

Johnny Sexton leads Bernard Foley 3-2 with the boot at the minute.

And that's the interval.

Grab a brew, brunch, whatever tickles your fancy... but don't stray too far.

A big second half coming right up.

Woah. Penalty party at the minute.

The Aussies are pulled up straight from kick-off, and remarkably Ireland could now head into the break with the lead.

Johnny Sexton, right in front of the posts from 30+ metres, makes no mistake.

Australia kick for the corner. They may be a man down, but are looking for a big score before the break in this decisive Test.

The gold and greens gather from the knock down, but Bundee Aki delivers a thunderous hit to keep the hosts at bay.

Ireland are penalised again, Conor Murray the offender. And this time Australia will go for the sticks.

Bernard Foley pops it over. Level pegging again.

Conor Murray just burrowing his way through a tunnel of bodies like a starving mole in hunt of dinner, but he'll go hungry... the TMO says he came up short.

There was an Aussie offside in there somewhere. So Johnny Sexton opts to stick another over the posts and give Ireland the lead.

Boos ring out around the Allianz Stadium.

The Sydney crowd is boiling over after that yellow card for Israel Folau.

Can Ireland make their one-man advantage count? Jacob Stockdale, just back on the field, looks to scurry down the left channel but is hauled down short.

CJ Stander pops out to Jack McGrath, he's stopped. Now Conor Murray goes for the pads at the bottom of the posts.

We'll have a TMO to see if he's found it.

Ireland back up to 15 as Jacob Stockdale's time-out comes to an end.

Peter O'Mahony looks in a bit of trouble, mind. He falls awkwardly after climbing for a high ball with Israel Folau. The medical team are on, the skipper's heading off on the cart.

And now it will be Folau heading for the bin. After a quick look at the TMO, he's adjudged to have tugged O'Mahony down in the air.

He's not happy about it...

Ireland can build more pressure here from the line-out.

The visitors keep the ball moving and Johnny Sexton, with an advantage in the bag, sees his attempt at a throughball charged down.

It's a chance to convert from right in front of the sticks, though.

Sexton makes no mistake.

Green shirt after green shirt thunders into a wall of gold, until Peter O'Mahony wriggles through the line and Ireland spin it left.

The visitors get within five metres, Johnny Sexton pops back inside to Devin Toner but the big forward fails to hold.

Ireland, with 14 men, could have the chance to hit back immediately here.

Australia give away another needless penalty as Sekope Kepu is pulled up for not rolling away, and the visitors turn to the powerful boot of Conor Murray from long range...

It's high, looping left, too far left!

Murray drags it wide of the sticks. Australia maintrain their lead.

Bernard Foley takes the chance to edge Australia into the lead, squeezing his kick from wide out just inside the near stick.

Hang on, TMO time... Jacob Stockdale looks to have led with his arm into the neck of Nick Phipps.

The Ireland winger is in trouble. Yellow card, 10 minutes to sit and think about that one...
