The Australians had the better of the opening two Tests against the world number one Proteas only to be crushed by 309 runs in the series decider in Perth last week.
Sri Lanka are ranked sixth in the world, have not won in 10 Tests in Australia over 25 years and are rated outsiders to upset Clarke’s team in the three-Test series, beginning in Hobart today.
Former Australian quick Rodney Hogg has rubbished the Sri Lankan attack as the “worst ever” to come to Australia, with Nuwan Kulasekara, Shaminda Eranga and Chanaka Welegedara only having 38 Tests and 99 wickets between them.
“The opposition is irrelevant to how you judge yourself as players,” he said.
“Our goal is not to come out and play the same way against Sri Lanka as we did against South Africa.
“We have to learn from that series, take the positives — and I thought there were a lot of positives — and the areas where we need to get better, we need to make sure we do that.
“I’m sure that if we improve on the series against South Africa, we’ll continue to have success,” he said.
Meanwhile, Mahela Jayawardene said he will give up the captaincy after Sri Lanka's current Test and one-day tour of Australia, with Angelo Mathews seen as his likely replacement.
The 35-year-old said it was time for a younger leader and nominated Mathews, his vice-captain, as ideal to assume the role.
