Saturday's clash between the Wallabies and Springboks in Brisbane is also an interesting watch for the neutral All Blacks fan.
Both nations are big rivals of the defending world champions and both have also been struggling for form of late.
South Africa are coming off their first ever Rugby Championship defeat in Argentina while the Wallabies have lost their last six tests going back to last year's Rugby World Cup final.
A Springboks defeat could leave the All Blacks 10 points clear, if they beat the Pumas, with one hand effectively on the trophy.
A Wallabies defeat would add more pressure on coach Michael Chieka and leave their title defense in tatters.
So which side would you rather win on Saturday?
Some key stats ahead of the clash:
- South Africa have won four of their last six games against Australia, though the Wallabies will be aiming for back-to-back wins against the Springboks for the first time since 2012 after a 24-20 win in their last encounter.
- Australia have won six of their last seven games against South Africa when playing on home soil, including each of the last two such iterations of this fixture.
- The Wallabies have won only two of their last seven games at Suncorp Stadium (D1,L4), though their most recent victory there was a 24-20 triumph over South Africa.
- Overall, the Wallabies have won eight of their nine games against South Africa at Suncorp Stadium, including their biggest ever victory over the Springboks in July 2006 (49-0).
- Australia need only two more for 100 tries at Suncorp Stadium, only at two other venues (Ballymore Stadium & Sydney Cricket Ground) have they managed to crack triple digits.
- South Africa will be looking to avoid back-to-back losses for the first time since losing four on the bounce between November 2014 to August 2015, which included a defeat to Australia at Suncorp Stadium.
- The Springboks have won just three times away to Australia since the turn of the century, those victories coming four years apart in August 2005, August 2009 and September 2013.
- Bryan Habana has scored 65 tries in a 119 Test career; his next try against Australia would see the Wallabies become the first opposition against whom he has scored 10+ tries.
- Habana's try against Argentina meant he overtook David Campese (64) as the top try scorer for any Tier One nation and he sits just four tries behind Daisuke Ohata (69) as the top international try scorer ever.
- David Pocock has won five turnovers in the competition so far, two more than any other player.
