Rugby Championship AS IT HAPPENED: Furious Wallabies comeback comes up just short in Sydney

Argentina flyhalf Santiago Carreras punished an undisciplined Australia with 23 points off the tee as the Pumas held on grimly for a 28-26 win in Sydney on Saturday to breathe new life into their Rugby Championship campaign.

A try-fest beckoned in afternoon sunshine at Allianz Stadium but Argentina needed only one through captain Julian Montoya, with Carreras doing the damage with seven penalties and a conversion in front of a sell-out crowd.

A week after letting a 14-point lead slip in a 28-24 defeat to Australia in Townsville, Argentina saw most of a 21-point advantage erased in the final quarter as the Wallabies roared back through two Filipo Daugunu tries and another for Andrew Kellaway.

James O'Connor's conversion of Daugunu's second try put the Wallabies within two points in the 80th minute but their final stand ended after 11 phases with an errant pass.

The Pumas swooped on Max Jorgensen at the Wallabies' tryline to claim a penalty and close out a rousing win after having their hearts broken in Townsville.

"It was so emotional in the last 15 minutes," said Carreras, who slotted all eight of his kicks at goal.

"It was such an amazing game to watch (for the crowd). I'm really proud of the boys for this win."

Australia came to Sydney with momentum after Angus Bell scored a try six minutes after the final hooter in Townsville to beat the Pumas.

But the hosts were left to rue another slow start against the South Americans.

"Absolutely spent. Devastated," said loose forward Fraser McReight.

"A credit to Argentina. We did the same thing last week. Gave them a big head-start and they're a great team.

"The effort from the lads to dig in especially in that second half, to come back from where we were... just spent."

Home centre Joseph-Aukuso Suaalii scored the first try in the fifth minute, dragging two Pumas over the try-line.

But it was otherwise a dreadful start by the Australians.

Tane Edmed, wearing the Wallabies' No.10 shirt for the first time, had a clearing kick charged down by hooker Montoya, who followed up with a try in his 50th Test as Pumas captain.

A yellow card for winger Jorgensen for a deliberate knock-down left the Wallabies scrambling and the penalties piled up as the Pumas dominated the collisions.

Carreras' seventh penalty put the Pumas 28-7 up in the 64th minute before the game turned on its head when he drew a yellow card for another deliberate knock-down.

In a two-minute burst, fullback Kellaway and winger Daugunu each crossed for tries to pull the hosts within nine points with 12 minutes left.

As the clock ticked over into the 80th minute, the Wallabies rode their luck to within two points.

Kellaway threw an apparent forward pass to Daugunu as he bolted down the left wing to score his second try but the score was allowed to stand, leaving Pumas players incensed.

Soon the Pumas were celebrating victory, though, when Jorgensen was penalised for not releasing the ball, mowed down by replacement centre Justo Piccardo a minute after the final siren.

Wallabies captain Harry Wilson also laments a lack of discipline.

"We made it really hard for ourselves, discipline let us down badly there," Wilson says.

"We are normally a disciplined team. We have a lot of points in us but a lack of discipline made it hard for us. The support has been truly special and we're going to keep trying to earn it. It really does lift us."

Wallabies flanker Fraser McReight is knackered after another huge shift.

"Absolutely spent, absolutely devastated," McReight says.

"Gave them a big head start and they're a great team. The support here was unbelievable. I'm so proud to be Australian and to see the gold here was special."

A man draped in an Argentina flag now jumps the fence and beats a couple of defenders before being tackled.

A furious Wallabies comeback has come up just short as Argentina hold on for a deserved 28-26 win in Sydney.

Another thrilling Test but Australia pay for poor discipline.

That controversial late try at least gives them two crucial points as the Wallabies scored four tries to one.

"An absolute thriller in Sydney," Sean Maloney says.

Man of the match Santiago Carreras says it's "just mental."

We have a grandstand finish on our hands!

Filipo Daugunu's second try stands despite what looked to be a forward pass from Andrew Kellaway.

The Pumas lead has been cut to 28-26 with time almost up.

The Wallabies are cruelled by a tough forward pass call as Fraser McReight's skilful overhead tap to Max Jorgensen is probably 1cm forward.

Argentina are back to 15 men and lead 28-19 after 76 minutes.

Australia running out of time.

The Wallabies go bang, bang through Filipo Daugunu!

Incredible scenes as the Wallabies burst into life and the replacement winger dives to score in the left corner.

James O'Connor can't convert and Argentina lead 28-19 after 68 minutes. Wow!

And the Wallabies make them pay immediately as Andrew Kellaway ignites Allianz Stadium by slicing through for a try!

Slick hands from Joseph-Aukuso Suaalii put the fullback through a hole in front of 41,912.

Argentina lead 28-14 after 67 minutes.

Santiago Carreras has finally blotted his copybook.

He's sinbinned for a deliberate knockdown and the Wallabies now have a slight sniff with 15 on 14.

That's a harsh penalty against Wallabies captain Harry Wilson, as Pumas halfback Agustin Moyano runs into him as he attempts to retreat from a ruck.

"I'm not sure where Harry Wilson's supposed to go," Tim Horan says.

Santiago Carreras' perfect kicking day continues and Argentina now lead 28-7 after 64 minutes.
