Having finally made amends for the defeat of their 1997 counterparts by Ian McGeechan's Lions, the current generation of Boks are now in total command of the 2009 Tri Nations.
Three successive home wins over the All Blacks and Wallabies was followed by victory in Australia last weekend, leaving South Africa needing just a single point from their final two matches on the road to complete their first Tri Nations triumph since 2004.
But de Villiers, who took over from Jake White in January 2008, has seen enough in training to suggest that his side will continue to push on rather than rest on their laurels.
"In a team sport you never know when you are at the top," said de Villiers, as he prepares his side for Saturday's encounter with the Wallabies.
"What I do know is that this team can go much higher. There is so much potential that has not been tapped.
"Now that we trust each other, we can get so much better by concentrating on the smaller things that will add up to a bigger picture that our supporters will love."
The Springboks side for this weekend's clash with the Australians features a single change to the starting XV and another to the replacements bench. Both changes are enforced, with Odwa Ndungane coming in for the injured JP Pietersen on the right wing and back row Danie Rossouw replacing Andries Bekker after the lock forward also picked up an injury in Perth.
Morne Steyn, the hero of the Lions series, is again named at fly-half, while Ruan Pienaar retains his place at full back.
