The Springboks have won just one of their last eight matches against the Wallabies, their only victory coming in Pretoria in 2010.
The Wallabies ran over the top of South Africa to claim a 26-19 win in Perth three weeks ago.But Springboks captain de Villiers said recent improvements to the squad will give his side a strong chance of victory.
"We really do believe that we've improved over the last two weeks," de Villiers said.
"We believe the guys coming in can make a difference."
De Villiers said his side's inability to remain focused was to blame for their losing results.
"Doing it for 80 minutes ... I think that's been the problem," the South African said.
The Springboks have suffered a continual critique of their performance but de Villiers stressed the high expectations would help nurture success.
"I think as soon as we drop our standards and expectations of the Springboks team then I think we're on the wrong track," de Villiers said.
"You're not going to become a world-class, world-beating team overnight, but that's definitely what we're striving towards and we believe we're getting there, slowly but surely."
Despite a significant player turnover since the World Cup in 2011, de Villiers accepted it was the current side's responsibility to make up for past failures.
"One out of eight I think it is that we've won and that not good enough for us," de Villiers said.
"So we've sort of inherited that record but it's our job to rectify it and change the result on Saturday."
