The Wallabies left on Monday for South Africa aiming to regain momentum and end a 22-year losing run against the Springboks in Cape Town this weekend.
The Wallabies and Springboks, who face off on Saturday, are both on 10 points, six points behind tournament leaders New Zealand with two Tests left in the southern hemisphere series.
Loose-head prop Slipper said the tour to South Africa and Argentina was a chance for the Wallabies to regain the momentum they lost after their 51-20 humiliation to the All Blacks in
Auckland last month.
Australia have subsequently beaten South Africa 24-23 and Argentina 32-25 in home Tests.
Meanwhile, All Black pivot Aaron Cruden has been suspended for two matches after going out drinking and missing the New Zealanders' flight to Argentina.
Coach Steve Hansen said Cruden, who has been New Zealand's first-choice fly-half in the absence of the injured Daniel Carter, would not play against Argentina in La Plata on Saturday or South Africa in Johannesburg a week later.
The All Blacks called up Canterbury pivot Tom Taylor to replace Cruden, although Beauden Barrett is favourite to start in the number 10 position against Argentina.
