A hat-trick from in-form Andrew Kellaway saw Australia close out their Rugby Championship campaign with a 32-17 victory over Argentina on Saturday.

Kellaway moved onto seven tries for the 2021 tournament in a one-sided contest on the Gold Coast as the Wallabies followed up last week's 27-8 win in style.

Dave Rennie's men have now won four Tests in a row for the first time since November 2017, while Argentina are on a six-match losing run, their worst such streak in two years.

Quade Cooper's 10th-minute penalty set Australia on their way against an Argentina side missing six players due to an unauthorised trip to Byron Bay.

Tomas Lavanini's repeated infringements in the lineout earned him a yellow card and Folau Fainga'a darted over for the first try from the resulting play.

Fainga'a and Rob Valetini combined to free Kellaway for his first try of the contest, with Samu Kerevi bursting through after patient build-up to make it 20-3 after the break, Emiliano Boffelli having kicked a penalty.

The Wallabies by now were in cruise control, Kellaway finishing with aplomb after more good build-up, and his hat-trick try in the same corner was served on a plate by Len Ikitau's clever lay-off.

A weary Pumas side had something to celebrate when debutant Thomas Gallo powered through near the posts, as Australia brought on 38-year-old Greg Holmes – now the oldest player to feature for the Wallabies since World War II – for his first cap since 2016.

Gallo got a late second after a pile-on at the try line to make the scores a little more respectable.

Rennie's men showing great promise

Kellaway, who now has more than twice the number of tries of anyone else at these championships, was a good advert for Australia's renewed vibrancy under Rennie.

This is the first time they have won four Rugby Championship matches in a row and the third Test in 2021 in which they have scored at least 30 points.

Little pride for Pumas

Argentina, meanwhile, are on their worst losing run since a 10-game span from September 2018 to September 2019 and sit bottom of the standings on zero and with a points difference of minus 135 from their six matches.

They have also taken just one win from their past 13 Tests against Australia.

Ian Foster says New Zealand must raise their game when they attempt to complete a Rugby Championship clean sweep by beating South Africa on Saturday.

The All Blacks defeated the Springboks 19-17 last weekend to maintain their 100 per cent record and seal the title.

New Zealand can complete a first Southern Hemisphere 'Grand Slam' since 2017 if they make it six wins out of six in their last game of the tournament against the world champions at Cbus Stadium.

Anton Lienert-Brown returns from injury at centre, with Rieko Ioane switching to the left wing and Sevu Reece starting on the right.

Luke Jacobson comes in at number eight, while Brad Weber gets the nod at scrum-half as Richie Mo'unga has to settle for a place on the bench along with TJ Perenara and Damian McKenzie.

Head coach Foster is demanding improvement from the newly-crowned champions on the Gold Coast.

He said: "We've achieved the Championship title, which we're really proud to have achieved.

"The fact that we now have the chance to achieve a potential Grand Slam against our Southern Hemisphere opponents is pretty special. I'm excited by that, and it has already given this weekend's Test an edge."

He added: "We learnt some lessons last week.  We didn't look after the ball as well as we could have and some of our work at the ruck wasn’t as good as we wanted. We have to lift our performance in that area and the team is keen to get that right this weekend."

Springboks coach Jacques Nienaber made two injury-enforced changes, with Ox Nche starting at loosehead prop and Trevor Nyakane switching to tighthead after Frans Malherbe was ruled out due to a neck injury.

Jasper Wiese comes into the matchday squad as a replacement as third-placed South Africa attempt to end the tournament on a high note.

New Zealand: Jordie Barrett, Sevu Reece, Anton Lienert-Brown, David Havili, Rieko Ioane, Beauden Barrett, Brad Weber; Joe Moody, Codie Taylor, Nepo Laulala, Brodie Retallick, Scott Barrett, Akira Ioane, Ardie Savea (captain), Luke Jacobson.

Replacements: Asafo Aumua, George Bower, Ofa Tuungafasi, Patrick Tuipulotu, Ethan Blackadder, TJ Perenara, Richie Mo'unga, Damian McKenzie.

South Africa: Willie le Roux, Sbu Nkosi, Lukhanyo Am, Damian de Allende, Makazole Mapimpi, Handre Pollard, Faf de Klerk; Ox Nche, Bongi Mbonambi, Trevor Nyakane, Eben Etzebeth, Lood de Jager, Siya Kolisi (captain), Kwagga Smith, Duane Vermeulen.

Replacements: Malcolm Marx, Steven Kitshoff, Vincent Koch, Franco Mostert, Jasper Wiese, Herschel Jantjies, Elton Jantjies, Frans Steyn.

Six Argentina players have been ruled out of facing Australia in the Rugby Championship on Saturday after making an unauthorised trip to Byron Bay.

Pablo Matera, Joaquin Diaz Bonilla, Felipe Ezcurra, Santiago Medrano, Santiago Socino and Sebastian Cancelliere were stopped at the state border when they attempted to return to their Gold Coast base from New South Wales on Wednesday.

Manager Lucas Chioccarelli and video analyst Rodrigo Martinez were also prevented from entering Queensland due to coronavirus rules.

The Argentine Rugby Union stated that the players will not be available to face the Wallabies in their final match of the tournament at Cbus Stadium this weekend.

Rugby Championship organiser SANZAAR said in a statement: "SANZAAR has informed Argentina Rugby that all members of this group are now ineligible to participate further in The Rugby Championship as they have breached tournament rules.

"SANZAAR is very disappointed that such a breach has occurred given the clear rules that are in place to ensure the health and safety of all players and staff, and compliance with all relevant health orders."

The Pumas are bottom of the table, having failed to pick up a point from five matches.

Meanwhile, Greg Holmes will become the oldest player to feature for opponents Australia since World War II at the age of 38 after the prop was named among the replacements by Dave Rennie.

Darcy Swain and Pete Samu come into the side, while back-rower Sean McMahon will also start on the bench as the Wallabies eye a fourth successive win to secure second place behind champions New Zealand.

Australia: Reece Hodge, Jordan Petaia, Len Ikitau, Samu Kerevi, Andrew Kellaway, Quade Cooper, Nic White; James Slipper, Folau Fainga'a, Taniela Tupou, Izack Rodda, Darcy Swain, Pete Samu, Michael Hooper (captain) Rob Valetini.

Replacements: Lachlan Lonergan, Angus Bell, Greg Holmes, Matt Philip, Sean McMahon, Jake Gordon, James O'Connor, Tom Wright.

Argentina: Juan Cruz Mallia, Matias Moroni, Lucio Cinti, Santiago Chocobares, Emiliano Boffelli, Santiago Carreras, Gonzalo Bertranou; Rodrigo Martinez, Julian Montoya (captain), Enrique Pieretto, Guido Petti, Tomas Lavanini, Juan Martin Gonzalez, Marcos Kremer, Rodrigo Bruni.

Replacements: Facundo Bosch, Thomas Gallo, Eduardo Bello, Matias Alemanno, Francisco Gorrissen, Gonzalo Garcia, Domingo Miotti, Mateo Carreras.

New Zealand are on the brink of landing the Rugby Championship title ahead of their 100th Test against holders South Africa in Townsville on Saturday.

The All Blacks have been in a class of their own, taking maximum points from four matches to put one hand on the trophy and replace the world champions at the top of the rankings.

South Africa are smarting from back-to-back defeats to Australia, leaving them 10 points adrift of the leaders with two games against Ian Foster's side to play.

Australia are just a point behind the Springboks ahead of their clash with Argentina this weekend.

Here, we use Opta data to preview the double-header at Queensland Country Bank Stadium.

NEW ZEALAND V SOUTH AFRICA

Form

There appears to be no stopping New Zealand at the moment, with their winning run standing at nine matches following back-to-back defeats of Argentina.

The last time the All Blacks enjoyed a longer winning streak was in October 2016, when they completed a run of 18 on the spin.

South Africa, on the other hand, are two without a win and have not had a worse run since losing four in a row from October to November five years ago.

Ones to watch

Akira Ioane is one of eight New Zealand players to be facing South Africa for the first time. Starting at blindside flanker on Saturday, his potency in the Springbok half could be key – only Jordie Barrett (nine) has beaten more defenders in opposition territory than Ioane (eight) in the 2021 competition.

Lood de Jager is back following concussion to reunite with Eben Etzebeth in the Springbok second row. They, along with Argentina's Guido Petti, are the only players to have stolen multiple lineouts at this year's tournament.

AUSTRALIA V ARGENTINA

Form

Australia are on a high after two impressive wins over South Africa, playing some entertaining rugby in a 30-17 bonus-point win in Brisbane last weekend.

Argentina are rooted to the foot of the table without a point from four matches, with a points difference of minus 101.

Each of the last two Tests between these nations ended in a draw. Only once in Test history have any tier one nations drawn three in a row (England vs France from February 1959 to February 1961).

Ones to watch

Australia captain Michael Hooper tends to enjoy facing Argentina: his most recent five home Tests against the Pumas have yielded a personal haul of four tries and one assist.

Argentina's best hope of springing a surprise could rest on the shoulders of Marcos Kremer, who is the only player in this championship to have registered more than 30 in both carries (31) and tackles (48). Another big showing from flanker Kremer might give the South American side a sniff.

New Zealand returned to the top of the world rankings with their win over Argentina on Saturday, but coach Ian Foster is more concerned by the upcoming double-header against South Africa.

With a 36-13 defeat of the Pumas in Brisbane – their ninth consecutive Test win – New Zealand leapfrogged South Africa at the summit.

Foster's side also moved 10 points clear at the top of the Rugby Championship table and could wrap up the title even with a defeat against the Springboks next time out – if the All Blacks secure a losing bonus or prevent their opponents earning a try bonus.

But the opportunity to test themselves against the world champions is of greater interest in what will be the 100th Test meeting between the teams.

Asked about New Zealand's number one ranking, Foster said: "My mindset is you've got to beat number one to be number one.

"It's not on our mind at all. I'm not saying that to downplay it. We're about to play South Africa next week, we'll get excited about that.

"We're more interested in winning a Test match than where we sit [in the rankings].

"If we focus too much on the other thing, we'll get tripped up and won't be there for very long, and that doesn't interest us either."

Of the South Africa matches, he added: "We love playing Test matches, but we really love playing South Africa, probably because of the amount of respect we've got for them.

"Over history, it's been an outstanding rivalry.

"We're not so much talking about number ones and number twos, we've got a chance to go to Townsville to play a foe we've got a lot of respect for and put ourselves in a pretty nice position in this championship."

New Zealand pulled further clear at the top of the Rugby Championship standings and closed on the title with a 36-13 victory over Argentina in Brisbane.

The All Blacks were as dominant in this nominal away Test as they had been in the previous clash last week, even if the scoreline was this time a little closer.

Patrick Tuipulotu, TJ Perenara, Tupou Vaa'i (twice) and Samisoni Taukei'aho each contributed tries for a fourth bonus-point win from four to move Ian Foster's men 10 points clear of South Africa ahead of a double-header against the world champions.

New Zealand had to wait only until the sixth minute for their opening try, as Will Jordan carried to the line after a break from Hoskins Sotutu, before Tuipulotu's power got the ball over.

After Emiliano Boffelli's penalty ensured Argentina would not go scoreless for a third straight Test against the All Blacks, the Pumas were soon on the back foot again.

New Zealand had a further three tries – for Jordan and Rieko Ioane twice – ruled out before half-time, but they were still able to successfully cross twice more, with Perenara stooping through following a scrum and pressure on the stroke of the interval producing a simple score for Vaa'i in the corner.

A flowing move from left to right created space for Taukei'aho after the restart, although Boffelli's excellent stretching catch on the left then allowed him to get the ball grounded before he was taken into touch by a combination of Jordie Barrett and Jordan.

That prompted an improved Argentina spell, yet the All Blacks countered effectively and Vaa'i was unmarked to complete the scoring.

Will makes it work... eventually

Jordan was influential in much of the All Blacks' best work, but he was also involved in two of their disallowed tries. The wing was just ahead of Taukei'aho before racing through to score and then played a forward pass of his own to Ioane following a superb take from Damian McKenzie's kick.

Jordan got it right for the first try of the second half, however, unloading a superb ball to Taukei'aho.

Celebration against the Springboks?

The All Blacks have now won nine Tests on the bounce, last enjoying a longer run between August 2015 and October 2016 (18 wins), and the next one should be special – their 100th meeting with the Springboks.

Anything less than a bonus-point South Africa win, with New Zealand failing to earn a losing bonus, would see last year's Tri-Nations champions crowned again.

Australia got the better of South Africa for the second week running as Len Ikitau and Marika Koroibete led the Wallabies to a 30-17 victory in the Rugby Championship.

Having triumphed 28-26 over the Springboks on the Gold Coast last week, Australia came out on top again in Saturday's tussle in Brisbane.

The victory takes Australia to within one point of the second-place Springboks on 10 points, who are five behind leaders and reigning champions New Zealand, who face Argentina in the later game.

Quade Cooper was the star for Australia last time out, converting eight kicks, though he missed his first two-pointer here after Ikitau had crossed following Faf de Klerk's early booking for knocking the ball from Nic White's hands.

Handre Pollard pulled the 'Boks to within two points with a long-range penalty, though Australia swiftly struck again, Ikitau once more finding the gap and this time Cooper hit his mark from the conversion.

Pollard hit another two penalties either side of a Cooper three-pointer as, back to their full count, South Africa attempted to turn the screw, yet even with Lachlan Swinton seeing yellow (after initially being given a red card for a high tackle) the visitors could not prise Australia's defence open before the break.

Lukhanyo Am finally managed to do so just after the break to nose South Africa ahead for the first time, but it was a short-lived lead, Cooper winning a penalty and converting it before Koroibete steamed in for his first.

Cooper made no mistake and, five minutes later, Koroibete helped himself to his second to wrap up the result – Jasper Wiese's late yellow adding more frustration for the Springboks.

No place like home

Australia are now undefeated in their past seven men's Tests against South Africa on home soil (W6, D1), although Saturday is the first time they have won by a margin of seven points or more in that span. It is also the first time the Wallabies have earned back-to-back wins in men's international rugby since October 2019.

South Africa's resistance stutters

Heading into the match, South Africa had conceded just 13 points in the final quarters of games in the tournament, fewer than any other team. However, Australia had scored the most points (27) in the last 20 minutes, and they took that tally to 39 with their 12 points scored between the 62nd and 68th minutes, breaking the Springboks' resolve in the process.

South Africa will attempt to spoil Michael Hooper's record-breaking Australia appearance when the Springboks go on a Rugby Championship revenge mission on Saturday.

Hooper will captain the Wallabies for a 60th time at Suncorp Stadium, surpassing the number of times George Gregan led Australia out.

A special occasion for the skipper will come six days after Quade Cooper marked his international return by kicking a dramatic winning penalty against the Boks on the Gold Coast.

Holders South Africa were consigned to a stunning 28-26 defeat in Queensland and trail leaders New Zealand by five points.

Australia are unbeaten in six Tests against the Springboks on home soil ahead of the round-four showdown, after achieving their first win of this year's tournament last weekend.

The All Blacks have maximum points from three matches and can take another stride towards regaining the title by beating Argentina.

Here, Stats Perform uses Opta facts to preview the Rugby Championship double-header in Brisbane.

AUSTRALIA V SOUTH AFRICA

Form

South Africa will be looking to avoid back-to-back defeats in men's Tests for the first time since November 2018.

Australia have not won back-to-back Tests since October 2019 and may need to show their staying power once again to get their hands on the Nelson Mandela Challenge Plate.

Dave Rennie's side have scored 27 points in the final quarter of games in this tournament, more than any other quarter of a match.

Nic White, James Slipper and Taniela Tupou come into the Australia team. Jacques Nienaber makes three changes to South Africa's matchday squad, with Marvin Orie and Trevor Nyakane starting. Cheslin Kolbe is not ready to return from injury.

Ones to watch

Andrew Kellaway scored Australia's only try in last week's win over the world champions.

The wing is the joint-leading try-scorer in the tournament with three, alongside David Havili and Malcolm Marx. 

With Lood de Jager absent due to concussion, Orie takes over at lock for South Africa.

De Jager has won a competition-high 22 lineouts, including three steals, so Orie has big shoes to fill.

ARGENTINA V NEW ZEALAND

Form

The All Blacks dished out a 39-0 thrashing to Argentina in round three, Luke Jacobson scoring two of their five tries.

New Zealand have kept the Pumas scoreless in each of their past two meetings and have only failed to beat them in two of 32 previous encounters.

Argentina have lost three consecutive Tests, having lost only twice in their 10 prior to that run.

Joe Moody comes into a much-changed All Blacks side and Ardie Savea returns as captain, while Samisoni Taukei'aho makes his first Test start. Patrick Tuipulotu and Ofa Tuungafasi are also among the starters.

Santiago Carreras starts for Argentina at fly-half, while Pablo Matera takes the number eight shirt as Mario Ledesma makes six changes.

Ones to watch

The versatile Damian McKenzie gets the chance to start a second Test at fly-half for the All Blacks.

Playmaker McKenzie can put on a show at number 10 and pull the strings in tandem with scrum-half TJ Perenara.

Pumas captain Julian Montoya won three turnovers in the defeat to the All Blacks last weekend and his tally of four is twice as many as any other player in the tournament.

Montoya has not missed any of his 40 tackles in the competition.

Damian McKenzie will start at fly-half in a Test for the first time in three years as New Zealand overhauled their XV for the Rugby Championship clash against Argentina.

All Blacks head coach Ian Foster has made wholesale changes after last week's 39-0 rout of the Pumas on the Gold Coast, with McKenzie to start at number 10 in Brisbane on Saturday having been introduced off the bench.

New Zealand's backline at Suncorp Stadium will feature only four players who started against Argentina last time out as the All Blacks look to maintain their 100 per cent record in the competition – Ardie Savea returning to captain the side.

"With five Tests in a row and a six-day turnaround between these two Argentinian Tests, we were always going to make some selection changes," Foster said. "Five Tests in a row demanded that. 

"But the good thing is that we have a group that has been focussing on the same opposition for the last two weeks, so our preparation time hasn’t been compromised.

"We are expecting a huge response from Argentina and we have to make sure we are prepared for that because we know what a wounded beast is like. The key is not so much how they respond, but how we respond. If we go into this Test match thinking it's just going to happen for us like last week without earning the right to have the scoreboard in our favour, then we are in trouble."

New Zealand have won 30 of their 32 previous men's Tests against Argentina (D1, L1), including their last two in succession. They have also won three of their four meetings on neutral territory in that time (L1).

The All Blacks have kept Argentina scoreless in each of their last two meetings – only twice since 1900 has any Tier 1 nation kept another Tier 1 nation scoreless for more consecutive games (England – four games against Ireland from 1956 to 1959; France – three games against Italy from 1959 to 1961).

New Zealand have won their last eight consecutive Tests by an average margin of 40 points. A ninth straight victory would equal their longest winning streak since a run of 18 victories from August 2015 to October 2016.

New Zealand: Jordie Barrett, Will Jordan, Rieko Ioane, Quinn Tupaea, George Bridge, Damian McKenzie, TJ Perenara; Joe Moody, Samisoni Taukei'aho, Tyrel Lomax, Patrick Tuipulotu, Tupou Vaa'I, Ethan Blackadder, Ardie Savea, Hoskins Sotutu.
Replacements: Codie Taylor, George Bower, Ofa Tuungafasi, Scott Barrett, Luke Jacobson, Finlay Christie, Beauden Barrett, Braydon Ennor.

Aaron Smith will play no further part in the Rugby Championship as the New Zealand scrum-half awaits the birth of his second child.

Smith started both victories over Australia at Eden Park last month but did not travel to face them in Perth at the start of September and was absent for last weekend's 39-0 win over Argentina.

The playmaker will also miss the upcoming clash with the Pumas and back-to-back showdowns with world champions South Africa, as he did not want to risk missing the arrival of his second child, which is due in November.

Smith will stay at home, with no guarantees he would secure a managed isolation space if he had to fly home earlier than expected.

The 32-year-old will instead play for Manawatu in the Bunnings Cup.

Smith could also miss the All Blacks' tour of the United States and Europe.

He said: "The door isn't completely closed to me joining the team for the Northern Tour if our baby comes early. 

"In this environment anything can happen, so I've got an open mind. At the moment though, I just want to focus on being here with my family and enjoying that time and playing for Manawatu. I can't wait to get the boots on again."

TJ Perenara and Brad Weber will battle it out for New Zealand's number nine shirt in the absence of Smith.

Quade Cooper made a sensational match-winning return as Australia got up and running in the Rugby Championship with a last-gasp 28-26 victory over South Africa on Sunday. 

Following back-to-back defeats to New Zealand to start the competition, veteran fly-half Cooper was named in the starting line-up for the visit of the world champions – his first international appearance since June 2017. 

The 33-year-old's kicking was exemplary, slotting through a seventh penalty and eighth successful kick of the game from 40 metres with the clock in the red to snatch the win at the death. 

Handre Pollard and Cooper scored two penalties apiece before Siya Kolisi's yellow card for a dangerous tackle on Tom Banks was pounced upon by Australia.

Samu Kerevi's excellent pass released Andrew Kellaway, who cut in off the right wing and dived in behind the posts. 

The Springboks responded well and Bongi Mbonambi powered over from the back of a driving maul after Matt Philip was sent to the sin bin for repeated ruck infringements, but the Wallabies still took an eight-point lead into the break. 

Willie Le Roux was shown a yellow card for a deliberate knock-on in the 52nd minute and he was joined in the bin by Folau Fainga'a before replacement hooker Malcolm Marx touched down in the middle of another driving maul. 

Marx did likewise in the 72nd minute for his second try to put the Springboks in front, but Damian Willemse made a costly miss when attempting to convert from the tee. 

And after South Africa conceded a penalty at the death for not releasing on the ground, Cooper made them pay with a winning kick. 

Quade a display

He may have made 70 previous appearances for the Wallabies, but Cooper only scored 10 points or more in six of those matches. His 23 points against South Africa was consequently his best display for his country.

Hooper at the heart

Cooper may have taken the headlines, but Wallabies skipper Michael Hooper was formidable in the pack. He made two of his team's three clean breaks and did not miss any of his eight tackles.

New Zealand turned on the style to ruthlessly dispatch Argentina 39-0 to make it three wins from three in the Rugby Championship.

Rieko Ioane, Sevu Reece and Dalton Papalii all touched down in a dominant first-half showing from the All Blacks at the CBUS Super Stadium in Queensland.

Luke Jacobson then scored twice in the second period to complete the most routine of wins for Ian Foster's side.

Ioane went over in scrappy fashion after 10 minutes when he reacted fastest to Bautista Delguy knocking a Beauden Barrett offload to ground.

Despite dominating ball and territory it took until three minutes before half-time for Reece to crash over, with Papalii following suit with time in the red following a drive from a line-out with Pablo Matera sent to the bin for the Pumas in the build-up due to persistent team infringements.

Jacobson had his first following a stunning offload from Barrett early in the second half and, after New Zealand were denied on three occasions by the TMO, he had a second with a strong run from the back of a scrum.

A late Jordie Barrett three-pointer added further gloss for a New Zealand side that was never troubled by a limp Argentina for who Nicolas Sanchez made a record 90th appearance.

Ioane a menace

Argentina were camped in their own 22 for the majority of the first half in no short part down to the work of Ioane.

The bulldozing centre, who prior to this game was the leader for metres gained in the Championship, consistently broke the lines and it was his quick reactions that got the All Blacks rolling.

Barrett bros almost combine for stunner

Shortly after Ioane's opener there was a moment of genius when Beauden Barrett's high kick was caught by brother Jordie deep into the try area and dotted down.

It was a sensational catch and ground by the full-back, who had absolutely no right to make the grab, but sadly his placing of the ball appeared to be just over the line.

Australia are looking for a lift and have turned to Quade Cooper to provide guile from number 10 against South Africa as the Rugby Championship resumes.

Three weeks on from the second round of games, Australia and the Springboks go head to head, and New Zealand tackle Argentina, with both games being played on Sunday at Cbus Super Stadium on the Gold Coast.

The Wallabies took a Bledisloe Cup drubbing at the hands of the All Blacks, losing all three games in that series, with two of those forming part of this tournament, so they are looking for a spark and will hope Cooper, making his first international appearance in over four years, can provide that.

The 33-year-old last featured, briefly, against Italy in June 2017 and now plays for Japanese team Kintetsu Liners.

His career looked to be in steep decline at one point, as Cooper lost his place in not only the Australia squad during Michael Cheika's reign as coach, but also fell out of favour with the Queensland Reds.

Now he is set for a 71st Test appearance, having been originally beckoned into Dave Rennie's squad as a training player.

South Africa make seven changes to their starting XV for the match, with number eight Duane Vermeulen selected to make his first appearance for the Boks since the 2019 World Cup final after recovering from ankle surgery.

There are changes afoot for New Zealand too, with lock Brodie Retallick named captain for the clash with Argentina as Ardie Savea sits the game out after taking a knock to the head last week.

Ahead of the crunch double-header, the third of six rounds of games in the championship, Stats Perform looks at the key Opta facts.

NEW ZEALAND v ARGENTINA

Form

The All Blacks are inevitably on a high after crushing the Bledisloe Cup aspirations of their trans-Tasman rivals and duly making a strong start to the championship. They have full-back Jordie Barrett available despite his red card against Australia last time out after the punishment was rescinded on appeal in midweek.

New Zealand have won their last seven men's Tests on the bounce by an average margin of 40 points per game. The last time they won more in succession was a nine-game streak from November 2017 to September 2018 which included a 46-24 win over Argentina.

They have not always had it easy against the South American powerhouses, though. Their clashes in last year's Tri-Nations were memorable, with Argentina scoring a stunning 25-15 win over the All Blacks on November 14, 2020, only to then lose 38-0 when they met again a fortnight later. New Zealand have won 29 of their 31 Tests against Argentina (D1, L1).

New Zealand have had just 12 minutes and 53 seconds of possession per game in this year's Rugby Championship, the lowest of any team in the competition. Despite this, they lead the competition in metres gained (615), clean breaks (15), and points scored (48) per game.

Argentina's two defeats to South Africa in the opening two rounds suggest they might find the going tough this weekend.

Ones to watch

Blindside flanker Akira Ioane has crossed the gainline on 17 of his 18 gainline carries for New Zealand in the competition so far. His 94 per cent rate is the highest of any player to have made at least 10 gainline carries in this tournament.

Retallick will carry the responsibility of leadership after he was favoured ahead of Beauden Barrett who, at fly-half, was judged to have enough going on without having to issue orders.

Coach Ian Foster said of Retallick, who has returned to Test action this year after a spell in Japan: "He's back, he's confident, he's got the smile on his face, and that's part of the biggest thing with Brodie. When he's settled and he loves the environment, then he can go out and express himself.

"And I don't want a lot to change with that captaincy band. It's one of the challenges of giving it to someone like Brodie, do you force him into someone that he's not? But I'm really comfortable. He knows his role, he's clear and the boys certainly want to follow him."

Discipline will be important for both sides, with Argentina having received six yellow cards and one red card in their last six men's Tests, including two yellow cards against the Boks last time out. They had received only one yellow card and one red card in their previous 25 Tests.

SOUTH AFRICA v AUSTRALIA

Form

After the tussle between the All Blacks and Pumas, perhaps this can be considered the headline match of the weekend, an embattled Australia facing World Cup winners who are aiming for a statement victory.

For COVID-19 reasons, Queensland is staging the remainder of this tournament, and Australia coach Rennie will look for a response from his players to their sequence of losses.

The three-in-a-row streak is a concern, and the last time the Wallabies lost more in succession was a four-game stretch from June to August in 2018. They lost twice to Ireland and twice to New Zealand before ending that losing run with a 23-18 success against South Africa.

Australia have won 19 of their last 24 men's Tests at home against South Africa, logging just three defeats in that span (D2). They are undefeated in their last five such fixtures (W4, D1), yet each of those games has featured a margin of fewer than seven points on the day.

It could be tight again, with South Africa having won 15 of their 18 Tests since the beginning of 2019. They have won their last four on the bounce, and their 83 per cent win rate since the beginning of 2019 is the best of any top-tier team in that time.

South Africa defeated Argentina 29-10 in the second round, while Australia went down 38-21 to New Zealand in Perth.

The Springboks have missed the fewest tackles per game (16) so far in the championship and have the highest tackle success rate (89 per cent) of any team. Australia’s tackle success rate of 82 per cent is the lowest of the four sides, but the context is that they were facing the All Blacks.

South Africa have created 20 mauls throughout this tournament, which is twice as many as any other team and five times as many as Australia (4); the Springboks have gained 56 metres and scored one try from those mauls.

Ones to watch

Australia scrum-half Tate McDermott has beaten nine defenders in this year's Rugby Championship, the second-most of any player (Akira Ioane – 12). He beat seven defenders against the All Blacks in the last round, and only twice in the last decade has any scrum-half from a tier one nation made more (Antoine Dupont 9, Francois Hougaard 8).

He therefore has a pivotal role to play, and how he combines with Cooper will be keenly observed.

Rennie said he was "thrilled" to be able to be giving Cooper another chance to show his quality at this level, and it remains to be seen whether this is a one-off comeback or something that might have longer-term legs.

Michael Hooper will match George Gregan's record of 59 matches as captain of Australia as he wins a 112th cap, and there are other landmarks set to arise. Reece Hodge, who starts on the bench, and Allan Alaalatoa will each win 50th caps.

Rennie described the match as "a huge occasion" for Hooper, hailing his longevity as "testament to his leadership and resilience".

Boks coach Jacques Nienaber said of the occasion: "Australia pose a strong threat with their running rugby and they like to keep the ball in play. They will also be playing in front of a charged-up home crowd, so it will be good to have these experienced players back as they know what it takes to perform in big matches."

South Africa have won their last two Tests on the bounce against Australia, as many as they had won in their eight encounters prior (D2, L4). The last time they won more successive games against the Wallabies was a three-game winning stretch from September 2012 to September 2013.

Ian Foster and Dave Rennie backed the law change over red cards in the Rugby Championship after New Zealand completed a Bledisloe Cup sweep over Australia on Sunday.

Jordie Barrett scored the game's opening try in Perth, setting New Zealand on the way to a 38-21 triumph that means they have won all three Tests against their trans-Tasman rivals this year.

However, the full-back did not last long after scoring, dismissed for dangerous play after catching Wallabies winger Marika Koroibete in the face with a boot while catching a high ball.

All Blacks boss Foster felt the decision to send off Barrett was a little harsh, particularly as it could lead to a suspension that has an impact on the rest of the Championship campaign.

"I was pretty surprised to be honest [that he got the red card]," Foster told the media. "We'll go and have a good look at it, but certainly we'll be putting together a case for that one.

"He just lost balance and you could see he tilted and you could see what happened.

"I feel for the refs in situations like this, because technically they saw things and they make their decisions. I get all that. Have we got a technique problem? No."

While Barrett did not feature again, the tournament is experimenting with a ruling where players who have been sent off can be replaced by a substitute after a 20-minute period.

The initiative allowed the All Blacks to be back at full strength early in the second half, by which time they were comfortably in charge of proceedings.

"It's why all the SANZAAR countries were pretty united in wanting to carry on this global trial," Foster said of the trial.

"It's easy to ask me my opinion because we were the ones on the end of it, so we probably benefited by only having a 20-minute red card. I get that.

"But we were keen supporters of that even before the game and today probably justifies that."

Wallabies head coach Rennie felt the red card was the right call, even if Barrett had not been malicious in making contact with Koroibete, but also backed the initiative on trial.

The hosts still trailed 18-0 at half-time and while they did cross three times after the break, New Zealand eased clear to claim a bonus-point victory that puts them top of the table after two rounds.

"I think it's good that we have a 20-minute red card at the moment, because it's certainly not malicious," Rennie said.

"But based on law, when you field a ball, kick your foot out and hit someone in the head, there's going to be repercussions for that. So, I think the decision is probably accurate, and the fact it's only 20 minutes is a good thing."

New Zealand cruised to a Bledisloe Cup clean sweep in 2021 thanks to a 38-21 victory over Australia in Perth, despite the first-half dismissal of Jordie Barrett. 

The All Blacks had lost 47-26 on their previous trip to Optus Stadium in August 2019 but there was to be no repeat result for the Wallabies, who had already lost twice to their trans-Tasman rivals in Auckland last month. 

Beauden Barrett kicked a pair of penalties to make it 6-0 to the visitors before putting his boot to good use in open play too, a clever grubber creating the chance for brother Jordie Barrett to get the opening try of the game. 

However, the full-back's involvement in the contest only lasted a further 12 minutes. Claiming a high ball, he caught Marika Koroibete in the face with an outstretched boot while still in the air, leading to a contentious red card for dangerous contact with the head. 

Despite being down to 14, New Zealand extended their lead before the break to 18-0 when David Havili grabbed the first of his two tries, the other coming just after the hour mark as the second half saw a glut of points. 

Folau Fainga'a gave Australia hope 10 minutes after the interval with a try that Noah Lolesio converted, yet the All Blacks responded impressively, moving the ball across the line for wing Will Jordan to waltz over. 

They also exploited turnovers ruthlessly, both Havili and substitute George Bridge crossing after Australia had lost possession, the latter benefiting from a superb kick into space by TJ Perenara.  

In between, Anton Lienert-Brown went over from Akira Ioane's inside pass near the touchline, New Zealand easing to a bonus-point triumph that sends them top of the Rugby Championship standings after two rounds. 

Substitute Nic White forced his way over for a second Wallabies try, while they had the last say in terms of the scoring with Tom Banks' 79th-minute effort converted by Reece Hodge, but the hosts were already condemned to another heavy loss that leaves them bottom of the table. 

Where there's a Will, there’s a way

Jordan's second-half try means he has now scored in six consecutive Test appearances, the best streak by any player from a Tier 1 nation since the beginning of 2010. His latest effort was put on a plate for him by his team-mates, with the impressive Ioane breaking free of a tackle to create the simple finish after some neat handling had stretched the Australian defence out wide.

Barrett off, All Blacks still march on

Koroibete was certainly at the centre of the early action. He had already seen a try ruled out by the TMO by the time he was hit by Jordie Barrett's boot. However, the Wallabies were unable to capitalise when having an extra man on the field, with the competition's rules allowing a replacement to come on after a 20-minute period.
