Springbok Coach Peter de Villiers admits fans have every right to feel disillusioned less than a month before South Africa launch their Rugby World Cup defence in New Zealand.

But de Villiers and captain John Smit urged fans to keep the faith, despite the full strength Boks fading to a 14-9 loss to Australia in Durban.

Smit was suitably concerned when the home side only led 6 nil despite dominating possession and territory in the first half.

The Springboks host the All Blacks in Port Elizabeth on Sunday and Smit says a big showing is imperative.

Springboks host the All Blacks on Sunday at 3am.
