CBA has announced three executive departures as Matt Comyn reshapes the leadership team ahead of his official start date of 9 April.
Group executives David Whiteing, Kelly Bayer Rosmarin and Melanie Laing will leave CBA in the "coming months".
The three departing executives are responsible for enterprise services, institutional banking and human resources, respectively.
Mr Whiteing is also CBA's chief information officer.
The soon-to-be-vacated executive positions – along with Mr Comyn's former role of group executive for retail banking – will be filled in the coming months, with a "global search" underway, according to Mr Comyn.
Announcing the departures, departing chief executive Ian Narev said senior leadership changes "inevitably" lead to reshuffles in senior teams.
Mr Comyn said: "As incoming CEO I am focused on building an executive leadership team that will work to exceed the expectations of our customers, the community and regulators; rebuild the trust and pride in our Bank; and enhance the financial wellbeing of every customer we serve."
