SA vs Oz: Proteas' bowlers must do better: de Villiers

"I felt really good in the first Test match, obviously I spent quite a bit of time on the field," de Villiers said.

"They put us out in the field for quite a few hours and my body did really well to go through that and I think it did me extremely well, to test it out and to see where I am at at the moment.

"And I think I passed with flying colours."

Meanwhile, Australia's injury-prone vice-captain Shane Watson will test his strained calf at training on Monday ahead of Thursday's second Test.

Veteran teammate Mike Hussey admitted he had no idea whether Watson would win his race against time and prove his fitness but he had no doubt Australia were a better team when he played.

"I believe he has been running, so that is positive," Hussey told reporters.
