[3] In August 2019, Katich was appointed as the head coach for Royal Challengers Bangalore, and was present at the 2020 IPL Player Auction in Kolkata in December 2019.

[6] He was selected to tour Sri Lanka with the national team the following season but suffered greatly from illness, including a debilitating bout of chicken pox.

Katich was fined for showing dissent during the fourth Test to umpire Aleem Dar along with captain Ricky Ponting.

Australia persisted with him throughout the VB Series and in South Africa, as Katich scored runs fairly consistently.

However, he struggled in the DLF Cup in September 2006; the next month he lost his place at the top of the order to Shane Watson, who impressed Ponting [citation needed] with some attacking displays against the West Indies and an Indian state team.

Aside from being given the honour of captaining NSW in the Pura Cup final against Victoria, Katich also contributed scores of 86 and 92 to lead the match on run aggregate[10] as he had done for the season overall.

It was the first time since Sir Donald Bradman that a player had scored 300 at the SCG, and an innings which the Sydney Morning Herald called "superb".

[12] Peter Roebuck later claimed Katich should be the Australian cricket captain after Ricky Ponting came under fire during the January 2008 SCG Test.

[13] During the coverage of the final, Damien Fleming described Katich as a left-handed V. V. S. Laxman for his dominant bottom hand and willingness to hit through the on-side.

[15] Despite his heroics, Katich, a former team mainstay, blamed Michael Clarke for effectively ending his career once he became captain in revenge for a post-match incident several years earlier which saw Katich grab Clarke by the throat following a row about the singing of Australia's team song in the dressing room.

[16] In October 2015, Katich was appointed as an assistant coach of Indian Premier League side Kolkata Knight Riders.

[18] On 18 February 2022, he resigned from the assistant coach role of Sunrisers Hyderabad due to differences with the franchise's auction strategy.

[24] His father, Vince, was a police detective who helped play a part in the capture of serial killers David and Catherine Birnie.

[26] Katich formerly held the role of football operations manager of the Greater Western Sydney Giants AFL club.
