South Africa captain Siya Kolisi is relishing their upcoming Rugby Championship clash against Argentina, insisting his side "all know what is at stake."

The Springboks have picked up two wins from their four matches at the tournament so far, one victory against both New Zealand and Australia.

The reigning champions are currently second in the standings, one point behind the Wallabies, with all four teams still in contention to win the trophy.

With Kolisi aiming to retain their Rugby Championship title, the Springboks skipper is ready for the challenge ahead against the Pumas.

"We all know what's at stake," said Kolisi.

"They are a team that brings physicality and skill, so they are certainly not going to just give this game to us. So, for the team, it will be about doing our best to give ourselves the best possible chance to win the match and stay in the running for the title.

"The Pumas are extremely professional on and off the field, and they always play with passion, so we are under no illusions about the challenge ahead.

"But at the same time, we want to do something we’ve never done before, and that’s to win back-to-back Rugby Championship titles in a row, so we have a lot of motivation within this group as well."

Australia, meanwhile, will be facing New Zealand at Eden Park in their penultimate match in the tournament.

The Wallabies have welcomed both Nick Frost and Harry Potter back into the starting lineup after they both recovered from injuries.

Frost is excited as Australia look to end New Zealand's 52-match unbeaten record at the venue.

"I think you definitely got to respect it, first and foremost," said Frost.

"They've done unbelievably well at this ground for a number of years. You definitely got to respect it but also it's something you look forward to as well, as a player and as a team and as a group. 

"We're really excited [about] the opportunity that we have to play them at this ground. We respect what it is, as that record… but also, like I said, we're super keen."
