Argentina claimed a rare win over Australia as the Pumas emerged 48-17 victors in an entertaining Rugby Championship clash on Saturday.

Australia had only lost one of their previous 14 Tests against Argentina, but the depleted Wallabies were clearly second best in San Juan as Michael Cheika's side got their first points on the table.

A fast start had the Pumas 14-0 up by the seventh minute thanks to tries from Juan Imhoff and Thomas Gallo, and just when Australia looked to have the momentum, another quickfire double courtesy of Jeronimo De La Fuente and Juan Martin Gonzalez had the hosts back in charge.

The second half was a much tighter affair until Gallo's second try of the day, the Pumas ultimately romping to an emphatic victory with more late tries from Emiliano Boffelli and Tomas Albornoz. 

A purposeful Argentina were helped to an early lead as a defensive mix-up saw the ball drop kindly in Australia's 22 for Imhoff, who darted over before a successful conversion.

They got their second try of the match in just the fifth minute as prop Gallo bundled over under the posts, with the extras added once again by Boffelli amid a ferocious start by the hosts.

Australia responded as James Slipper went over from close range following a well-worked lineout, and James O'Connor converted before also successfully kicking a penalty.

O'Connor looked to have put Australia in front with 21 thrilling minutes played, but an earlier infringement earned Argentina a reprieve that they duly took full advantage of.

De La Fuente beat two men and dotted down for a gutsy try after seemingly pulling his hamstring partway through his run, and another fine Boffelli kick opened up an 11-point lead.

The deficit was further increased five minutes later thanks to Gonzalez, who charged clear from outside the 22 following an O'Connor fumble, but Australia had a lucky escape soon after when Boffelli had a try harshly chalked off despite appearing to touch the line with the ball.

After a quiet start to the second period, the Pumas effectively put the game beyond Australia with 16 minutes to go.

Gallo again showed great strength to force his way over from close range, and Boffelli's conversion made it 36-10.

Len Ikitau quickly hit back with a try of his own and O'Connor kicked the extras, but Bofelli then touched down after chasing down a low kick and with the final action of the game, Albornoz ran in behind to cap a memorable win.

Gallo embodies Pumas' spirit

This was some performance from 23-year-old Gallo. The prop's power and sheer determination was routinely on display, and never more crucially than with his two tries.

The two efforts were very similar in style as he simply refused to be tackled, and the second of which essentially killed off any hope of an Australia comeback.

O'Connor frustrated

The mercurial fly-half was given the chance to impress in the absence of Quade Cooper, who suffered a serious Achilles injury in Mendoza last weekend, and he certainly had his moments.

One such instance was his disallowed try, a decision that looked pretty harsh at the time. But ultimately he just did not have the influence he might have expected, and was also the man caught in possession prior to Gonzalez dotting down.

Even a victory may not be enough for Ian Foster to keep his job when New Zealand lock horns with South Africa once again at Ellis Park on Saturday.

Foster was under massive pressure before the Rugby Championship started and a 26-10 defeat at the hands of the Springboks last weekend ensured the writing would appear to be on the wall for the All Blacks head coach.

That loss in Mbombela pushed New Zealand down to their worst ever world ranking of fifth, and they face another almighty battle against the world champions in Johannesburg.

Australia fought back to start the tournament with a 41-26 victory over Argentina, so the Pumas will be hungry for revenge at Estadio Bicentenario in round two.

SOUTH AFRICA V NEW ZEALAND

FORM

It is now five losses in six Tests for the wounded All Blacks and three defeats in a row. Only once in the past 70 years have they lost more than three games in a row - suffering five consecutive defeats from July to August in 1998.

South Africa have won six of their past seven home games in the Rugby Championship, including four on the bounce. It is the third time they have won four on the spin at home in the competition and they have never managed five straight wins in such fixtures.

The Springboks have won their past two meetings with New Zealand. The last time they won more in succession against the All Blacks was a three-game streak from July to September in 2009.

ONES TO WATCH

The vastly experienced Duane Vermeulen returns at number eight for South Africa after recovering from a knee injury. He replaces Jasper Wiese and will need to hit the ground running.

A standout selection for New Zealand was the inclusion of Richie Mo'unga at fly-half, with Beauden Barrett dropping to the bench a week after he was involved in a nasty collision with Kurt-Lee Arendse. Foster will look to Mo'unga to provide control and set the tempo, provided he gets the ball to enable him to pull the strings.

ARGENTINA V AUSTRALIA

FORM

Australia have lost only one of their past 14 Tests against Argentina, winning 11 and drawing two. The Wallabies have won their last three versus the Pumas; 10 of the wins being decided by margins of at least 10 points.

Argentina are winless in 10 Rugby Championship/Tri Nations game, losing eight and drawing two. They have lost their last seven in the competition and squandered a 19-10 half-time lead last weekend.

It is now five Rugby Championship/Tri Nations victories in a row for Dave Rennie's Australia side, their longest winning run in the competition.

ONES TO WATCH

Former Australia head coach Michael Cheika has turned to Gonzalo Bertranou to start at scrum-half. The pivot must get Argentina ticking and put the Wallabies on the back foot.

Another cruel injury blow for Quade Cooper has opened the door for James O'Connor to start at fly-half for Australia. The number 10 will know he has a great opportunity to put on a show just over a year before the World Cup starts.

James O'Connor will start at fly-half, while Rory Arnold and Lalakai Foketi have also been included in the Australia side to face Argentina in the Rugby Championship on Saturday.

O'Connor gets the nod to don the number 10 shirt in the absence of Quade Cooper, who suffered an Achilles injury in the 41-26 win over the Pumas last weekend.

Arnold has recovered from a calf injury and the lock will make his first Wallabies start of the year at Estadio Bicentenario.

Centre Lalakai Foketi has been handed a maiden start by Dave Rennie, partnering Len Ikitau, and prop Taniela Tupo is back in the team in San Juan after Allan Alaalatoa returned home for personal reasons.

Pone Fa'amausili is set to make his debut off the bench, while Irae Simone is also among the replacements.

Australia head coach Rennie said: "After a tough, physical game last week it's great to be able to call on the experience of guys like James and Rory and also see the team's excitement for La and Irae who get to wear the Wallaby gold again on Saturday.

"It's going to be a proud occasion for Pone and his family and it's a testament to him for the hard work and obstacles he's had to overcome to earn his first Test cap."

Australia team: Tom Wright, Jordan Petaia, Len Ikitau, Lalakai Foketi, Marika Koroibete, James O'Connor, Nic White; James Slipper (captain), Folau Fainga’a, Taniela Tupou, Rory Arnold, Darcy Swain, Jed Holloway, Fraser McReight, Rob Valetini.

Replacements: Lachlan Lonergan, Matt Gibbon, Pone Fa'amausili, Nick Frost, Pete Samu, Tate McDermott, Irae Simone, Reece Hodge.

James O'Connor wrested victory from the clutches of the Brumbies as his late try gave the Reds a stunning 19-16 win in the Super Rugby AU final.

The dramatic intervention came in the 85th minute, with the Brumbies down to 13 players and desperately defending their line after Darcy Swain and Henry Stowers were sin-binned.

Kalani Thomas picked the ball up from the back of a maul near the try-line and fed a pass to O'Connor, who skidded over between two Brumbies players to thrill the large crowd inside Suncorp Stadium.

It gave the Reds revenge for their loss to the Brumbies in the 2020 final, and saw the Reds follow up finishing top of the regular season this time around by landing the trophy they longed for, a decade on from their last Super Rugby title.

O'Connor scored all the Reds' points, with his four penalties keeping the home team in touch before he added the late try and capped it with an immaculate conversion, the last act of the match.

A third-minute kick from O'Connor had nudged the Reds ahead, but Tom Banks capitalised on great play from Noah Lolesio to nudge the Brumbies in front 10 minutes later.

Lolesio added the extras and two penalties before half-time, with O'Connor also booting a further penalty for the Reds, as the Brumbies led 13-6 at the break.

O'Connor missed a penalty early in the second half but then proved more precise from his next two shots at goal, either side of Rob Valetini being sin-binned in the 61st minute for a high tackle on Jock Campbell.

Lolesio gave the Brumbies a 16-12 advantage for the closing stages after the Reds were penalised for an offside, but despite Valetini returning to the field, the men from Canberra were soon in trouble.

Swain was yellow-carded in the 78th minute for collapsing a maul, and Stowers followed him off moments later.

The Reds were denied a try by the referee and match official after claiming they had rolled across the line, but they still had the energy and momentum, and fly-half O'Connor seized the moment when the ball reached him to the left of the posts, darting in to snatch glory.
