(Reuters) - South Africa fullback Damian Willemse says his side will have to cut their error count or face being punished by clinical Australia and New Zealand in their remaining Rugby Championship matches later this month.

The Springboks are coming off a series win against the British & Irish Lions and two victories over Argentina at the start of the Rugby Championship, where they were not punished by either opponent for what was at times sloppy play with ball in hand and under high kicks.
