Kallis scored an impressive 147 to help South Africa to a first innings total of 450 at the Gabba and then helped in the removal of two top order Australian batsmen with slip catches as the hosts were reduced to 111-3.
"I'm ready to go," he told reporters. "It's managing the workload as well, just got to be careful with that, but as far the body goes, it's alright for the moment."
With 12 788 runs, 280 wickets and the third highest number of catches (189) taken by a player in the longer form of the game, Kallis's status as one of the greatest all rounders is secure.
And with a newly transplanted head of hair, he shows absolutely no sign of contemplating the end of a Test career that began back in December 1995.
"I'm happy with the way I played," he said. "It was tough this morning. I thought Oz bowled really well and got the ball into good areas.
"I think I've been playing pretty well for the last couple of years," he added.
"I feel I've been getting into good positions. Hopefully I can carry on that, and you need a little bit of luck to go with that as well. Long may that continue."
Amla also scored a century as the Proteas piled on the runs but his innings was brought to a close with 104 on the board by an lbw decision that would have almost certainly been overturned had South Africa appealed.
Kallis said he had spoken with his Amla at the crease and suggested he refer the umpire's decision.
"It was a chat that we had, I said I thought it was the height that was maybe the issue there but he felt it wasn't going to go over because the umpire had given it," Kallis said. - Reuters
