The hosts held on for a what was a bizarre win agains the world champions. The Wallabies conspired to concede four yellow cards in the dying embers of the chaos but managed to end up on top, cuing wild celebrations on the field.
For Wiese, it was probably not the way he imagined celebrating his 50th cap in green and gold. For one, he came off the bench in the 47th minute and only managed three carries. And to be on the losing side for this group of Springboks is a rare occasion.
Nonetheless, the eighthman was looking for positives in the wake of the result.
"Being 25 points down and losing the game by four points in a matter of ten minutes, it just shows what this group is about," the 20-year-old told the press afterwards.
"Obviously we were chasing the game a bit at the end there, but I think one or two more minutes⦠'if' is always a dangerous thing.
"I'm proud of the boys, proud of the fight they showed, and this is such a special group. I think the last 15 minutes showed it.
"It's valuable lessons we can take into next year if we are privileged enough to be a part of this group. I think we learnt some good lessons today. You always want to win while learning, but unfortunately sometimes it is not a good thing, but maybe necessary.
"This will be sore. It's definitely sore for me to lose here, but I think the fight is going to be bigger. I think everybody in this group just wants to give their best for South Africa and for this jersey, so I'm convinced that we will come back stronger."
The Boks will be back in action in November for the business end of the inaugural Nations Championship up north.
