Kallis finished as the 2nd highest run-scorer in the tournament and was its leading wicket taker with Man-of-the-Match awards in both the semi-final and the final.

[22] His breakthrough came in 1997, with 61 against Pakistan, and then two matches later, he salvaged a draw for South Africa with a fighting century against Australia at the Melbourne Cricket Ground.

[24] In 1998, he led South Africa to the ICC Champions Trophy title with two "Man of the Match" and the "Player of the Series" performances.

During this time, "Kallis blossomed into arguably the world's leading batsman, with a defensive technique second to none, and the adhesive qualities of a Cape Point limpet.

3 positions in the South African batting order after several players had been tried and discarded, and his stock rose exponentially from that moment."

[This quote needs a citation][7] Kallis is one of only four players in Test history (after Sir Donald Bradman and before Mohammad Yousuf and Gautam Gambhir) to make a century in five consecutive matches, which he achieved in the 2003/04 season.

[27][circular reference] In 2005, he set the record for the fastest half-century in Test cricket history, scoring 50 against Zimbabwe off only 24 balls.

As a result, he evolved into more of a batting all-rounder, a role in which he continued because of the emergence of Dale Steyn, Morné Morkel, and Vernon Philander.

The award was shared with Andrew Flintoff of England, his only serious competitor as the world's leading all-rounder, after the votes of the academy were tied.

[23] In 2006, Kallis was awarded the captaincy of South Africa for the third and final Test match against Australia when Graeme Smith withdrew with an injury.

He was, however, criticized in the press for scoring slowly, which cost South Africa momentum at key stages in the tournament.

For the second time in his career, Kallis scored twin centuries in a match, during the third Test of the series at his home ground, Newlands in Cape Town.

The Proteas also won two series against New Zealand and one against each of India, Pakistan, Sri Lanka, England, and Australia.

In September 2014, Kallis signed a one-year contract with the Sydney Thunder in the Big Bash League.

"[33] In the first Test starting on 17 December, Kallis scored 63 in South Africa's first innings, before he was dismissed by Mitchell Johnson, in the midst of a bowling spell consisting of 5/2 in 20 balls.

He then scored 57, while being involved in a 124-run partnership with AB de Villiers, as South Africa chased down 414, the second-highest fourth-innings run-chase in Test history.

[35][36][37] In the second Test in Melbourne starting on Boxing Day, Kallis struggled to be potent in Australia's first innings, taking 1/55.

Chasing just 183, Kallis was not required to bat, as South Africa completed their first Test series victory in Australia.

[38][39] In Australia's 103 run Third Test victory in Sydney, Kallis struggled, taking 1/54 and 0/13 with the ball, while scoring 37 and four with the bat.

Kallis injured his neck during the 2010 Champions League Twenty20 playing for the Royal Challengers Bangalore and missed the Twenty20 and ODI series against Zimbabwe.

[54] After the series, former Indian captain Sourav Ganguly said that he considered Kallis to be the "most-effective player" in Test cricket.

[55] Brett Lee named Kallis as the best player in the world in an interview after their victory for Kolkata Knight Riders for his performance in IPL 2012 final against Chennai Super Kings.

In December 2019, Kallis was appointed as batting consultant for South Africa national cricket team.

He’s not Brian Lara or Ricky Ponting in terms of aggression or flair but he is rock solid and, added to that, has every shot in the book.

Some people think he could move through the gears quicker when batting, and that is probably a fair argument on occasions, but the majority of the time he knows what he can do at the crease and believes South Africa has a better chance of winning if he stays there.

[59] Haigh also analysed how Kallis and Sobers were also polar opposites in certain ways: Sobers [was] all prowling grace and feline elasticity, with his 360-degree batswing and three-in-one bowling; [whereas] Kallis [is] all looming bulk and latent power, constructed like a work of neo-brutalist architecture.

[60] His sister Janine Kallis, five years his junior, was a cheerleader in Indian Premier League 2009 and is also a physiotherapist based in East London.

The Foundation with its partners hopes to provide talented youngsters the opportunity to reach their full sporting and academic potential.

Jacques Kallis participates in annual fundraising events for his Foundation, to which he invites fellow South African celebrities and cricketers like Mark Boucher and André Nel.
