The anthems have been sung and we're almost ready to go!
The two teams are heading out onto the field for the national anthems.
Australia: 15 Tom Banks, 14 Andrew Kellaway, 13 Len Ikitau, 12 Samu Kerevi, 11 Marika Koroibete, 10 Quade Cooper, 9 Nic White, 8 Rob Valetini, 7 Michael Hooper (c), 6 Lachlan Swinton, 5 Matt Philip, 4 Izack Rodda, 3 Taniela Tupou, 2 Folau Fainga’a, 1 James Slipper
Replacements: 16 Feleti Kaitu’u, 17 Angus Bell, 18 Tom Robertson, 19 Darcy Swain, 20 Pete Samu, 21 Tate McDermott, 22 Reece Hodge, 23 Jordan Petaia
Wallabies head coach Dave Rennie has also made two changes to his starting XV, with Nic White replacing Tate McDermott at scrumhalf and the dangerous Taniela Tupou coming in for Allan Alaalatoa in the front row.
Meanwhile, the Wallabies will be hoping Quade Cooper's fairy tale comeback continues today. The mercurial flyhalf kicked eight from eight last weekend and constantly kept the South African defence on its toes. It's also a big day for captain Michael Hooper, who will become the Wallabies' most capped skipper when he leads the side out for the 60th time, breaking the record of legendary scrumhalf George Gregan.
South Africa: 15 Willie le Roux, 14 Sbu Nkosi, 13 Lukhanyo Am, 12 Damian de Allende, 11 Makazole Mapimpi, 10 Handré Pollard, 9 Faf de Klerk, 8 Duane Vermeulen, 7 Franco Mostert, 6 Siya Kolisi (c), 5 Marvin Orie, 4 Eben Etzebeth, 3 Frans Malherbe, 2 Bongi Mbonambi, 1 Trevor Nyakane
Replacements: 16 Malcolm Marx, 17 Steven Kitshoff, 18 Vincent Koch, 19 Marco van Staden, 20 Kwagga Smith, 21 Jasper Wiese, 22 Herschel Jantjies, 23 Damian Willemse
The only two changes to the starting line-up sees Marvin Orie take over at lock from Lood de Jager, who suffered a concussion last weekend, while the livewire Trevor Nyakane returns at loosehead prop in place of Steven Kitshoff. Nienaber has once again opted for a six-two split of forwards and backs on the bench.
The Springboks came off second best in the first meeting between these two teams last weekend, going down 28-26 thanks to a last-gasp Quade Cooper penalty. The Boks admitted they weren't good enough in a number of key areas, but head coach Jacques Nienaber has chosen not to panic by mostly sticking to the same team that did battle last time around.
Good morning and welcome to our live coverage of the Rugby Championship clash between Australia and South Africa at Suncorp Stadium in Brisbane.
Quade Cooper get the 90th Test match between these two countries under way!
Matt Philip concedes an early penalty for obstructing the South African runners following an up-and-under.
Now it's a penalty against Faf de Klerk for straying offside at the ruck. Tom Banks will kick to relieve some early Bok pressure.
That was nearly a try for the Wallabies! Samu Kerevi breaks the line and the Aussies string a few passes together and nearly find the try line before a knock-on sees the Boks escape.
After several resets, Wallabies prop James Slipper is penalised for dropping his bind and the Boks can escape their own 22.
It's another penalty against the Wallabies after a solid line-out drive from the Boks takes them up the field. Pollard kicks for touch inside the Wallabies' 22.
The Wallabies are penalised for going early in the line-out and Pollard will kick for the corner again. Interesting decision here not to go for the three points.
Etzebeth is penalised for crawling on the ground just metres from the Australian try line. Silly penalty and the Wallabies escape.
It's a ridiculous penalty from Faf de Klerk as he slaps the ball out of Nic White's hands inside the Boks' 22 and that's a yellow card! The Wallabies were already playing under the advantage. Terrible from the Boks.
TRY! AUSTRALIA! IKITAU! 5-0. From the ensuing penalty and line-out, it's a simple backline move from the Wallabies that allows Len Ikitau to score! The Boks' defence was nowhere.
After a perfect game last weekend, Cooper misses his first kick at goal.
After another attempted line-out drive from the Boks, Matt Philip is penalised again. That's the third penalty the lock forward has given away. Pollard will go for the points here.

The Boks penalised straight from the restart after Nyakane turns over the ball and the Wallabies kick for the corner.
TRY! AUSTRALIA! IKITAU! 10-3. The Wallabies are in again. The Aussies continue to have the Bok defence at sixes and sevens. Slick passing and strong running sees the centre in for his second try. The big man Taniela Tupou slipped a few tackles in the build-up.

Faf de Klerk back on the field but that has cost the Boks 12 points.

TMO having a look at a potential high tackle on Duane Vermeulen from Lachlan Swinton.
The referee initially wanted to hand out a red card but after a chat with the TMO it's brought down to a yellow. Swinton in the bin for 10 minutes for leading with the shoulder, but luckily he just about made contact with Vermeulen's shoulder before his head.
That was much better from the Boks who string together a few phases before De Klerk finds touch right by the Wallabies try line.

Boks on the attack but a great counter-ruck from the Wallabies sees them turn over possession and kick for touch.
And that's half-time, with the Wallabies leading 15-12. Unfortunately for the Boks, many of the problems that plagued them last week - ill-discipline, poor execution and some dodgy defence chief among them - are back again this week. At least Pollard has come to the party this time to prevent the Wallabies from pulling away. Hopefully the men in green and gold can produce a better second 40.
Handre Pollard gets the second half under way!
TRY! SOUTH AFRICA! AM! 15-17. Great try from the Boks after Faf de Klerk takes a quick tap from a penalty advantage. They probe for the line before De Klerk sends through a grubber kick for Lukhanyo Am who falls down on the ball!

Bit of a kicking contest between the two teams ends with Le Roux calling for the mark inside the Boks 22.
It's a penalty to the Wallabies after Pollard strays offside. They were on the attack after a clever little kick over the top handed them a line-out inside the Boks' 22. Quade Cooper receiving some attention.
PENALTY! AUSTRALIA! COOPER! 18-17. Cooper puts the Aussies in front again after getting up off the ground.
The Boks have an opportunity to attack after the Wallabies knock on a high ball but then get in their own way and turn over the ball.
Boks overeager in the scrum and they give away the free kick.
Poor mistake from De Klerk to hand over possession and then the Boks infringe at the breakdown. Execution continues to be lacking for the world champions. The Wallabies have an attacking line-out inside the Boks' 22 but knock the ball on.
There was an attacking opportunity for the Boks there but they run it to close to the touch line and turn over possession.
TRY! AUSTRALIA! KOIROBETE! 23-17. Great try from the Wallabies after they exploit an overlap on the blindside. A strong run and beautiful offload from Tupou allows Koroibete to score in the corner. Australia simply playing better rugby at the moment.
CONVERSION! AUSTRALIA! COOPER! 25-17. Cooper's conversion is good.
TRY! AUSTRALIA! KOROIBETE! 30-17. It's loose play and another turnover from the Boks and the Wallabies get another chance to attack. The ball is recycled quickly and Koroibete charges over again.
Cooper's conversion is wide.
A penalty to the Boks and Pollard kicks for the corner. Last chance saloon for the men in green and gold.

It's another penalty against the Wallabies, who are pinned inside their own 22 at the moment. The Boks call for a scrum.

It's another turnover at the breakdown. Kerevi first to the ball there and the Boks give away possession for the umpteenth time today.
Jasper Wiese has gone flying into a ruck head first and the TMO is having a look here. It's a yellow card for the loose forward.
Final throw of the dice here for the Boks, who kick for the corner as the final hooter sounds.
Fittingly, the Boks can't secure possession from the line-out and that's that.
And that's the final whistle. It's consecutive wins over the Boks for Australia, who were full value for the win. The Springboks were unable to lift their game after their disappointing performance last weekend and must now try and regroup for back-to-back Tests against the All Blacks in the coming weeks. It will be a massive Test of this team's character.
