Siya Kolisi has sounded a warning to his Springbok team-mates ahead of this Saturday's Rugby Championship game against Australia at Newlands.
Flanker Kolisi replaced Francois Louw towards the end of the Test at Suncorp Stadium, where the Boks ran out 38-12 winners earlier this month.
And he believes Australia will want a response.
"Australia will come hard at us and try to fix the mistakes they made in Brisbane," he said,
Kolisi, simply known as 'Siya' to rugby fans, was caught up in a media scrum when he attended the opening of the Springbok Experience rugby museum in Cape Town on Tuesday.
"I was impressed when, even though Australia was so far behind (on the scoreboard), they never gave up trying and we battled to close out the game," he added when fielding questions.
"They are a good outfit, and they'll bring it on by stepping up their play a notch or two at Newlands."
Kolisi feels there are two aspects of the Boks' game that need to improve on Saturday.
"I think we slipped up our one-on-one tackling and our kicking game must improve."
"These are the things that we have chatted about this week. We also need to make sure that we move into better positions to get on top in the kicking game," the Stormers player added.
Kolisi, who also played as a substitute at Eden Park where the 14-man Boks lost 29-15 to the All Blacks two weeks ago, insists though that the Auckland game needs to be put to bed.
"We've put that game out of our heads and started focusing on Australia. What happened there is history now," he said.
"Our team for Saturday has not yet been named, so I don't know if I'll get a chance to run out at Newlands, which is my home stadium.
"I'm not really a man that likes to put emotion into rugby, but obviously it is going to be special for me playing in front of everyone in my town.
"The Boks have a good winning record at Newlands, but that won't win us the game on Saturday. We still have to pitch up and play well. We are not going to put the excellent Newlands records in our heads."
