Springboks coach Jacques Nienaber has demanded the world champions improve their discipline for the return clash with the Wallabies this weekend after their errors were brutally punished by Australian sharpshooter Quade Cooper.

The South Africans conceded 11 penalties in their 28-26 Rugby Championship loss on the Gold Coast Sunday and had to play for 20 minutes with 14 men after skipper Siya Kolisi and fullback Willie le Roux were sin-binned.
