Michael Clarke is confident veteran Ricky Ponting is ready to produce some of his best form for Australia over the next five weeks.
Australia are determined to win the three-match one-day series and subsequent test series against hosts South Africa, and captain Clarke believes Ponting is a key.
"I think he's just on the brink of having one of the best series of his career," said Clarke.
"I've seen him bat in Sri Lanka [90 not out in second ODI], he looked really good and he made some runs for Tasmania against WA [33, 87] the other day.
"I watched him bat in the nets [at Centurion this week] and I think this could be his series.
