South Africa host Australia on Saturday afternoon knowing they must secure a bonus point victory over their visitors to set up a final day Rugby Championship showdown with New Zealand.
Trailing the All Blacks by four points in the table following their 29-15 defeat in Auckland, the Springboks must run in at least four tries and sink Australia to keep their hopes of sealing the title alive.
When the sides met in Brisbane on September 7 South Africa registered a record 38-12 triumph and, despite Australia since recording a 14-13 win over Argentina, Heyneke Meyer's men are favourites to emerge victorious this weekend.
But can they seal that all-important bonus point as well?
You'll be able to see the drama unfold live on Sky Sports 2 from 3.15pm.
We'll also bring you live coverage of New Zealand's trip to Argentina from 11.40pm on Saturday night on Sky Sports 2.
The All Blacks will be targeting a substantial win of their own to maintain their 100% record - but they would be ill-advised to underestimate the Pumas, who were narrowly denied their first Rugby Championship win in Perth last time out.
Make sure you don't miss it.
