Dr Andrew McMullan has been appointed the chief data, digital, and AI officer at Westpac, effective from September 2025.
Currently the chief data and analytics officer of Commonwealth Bank of Australia, McMullan will use his experience to drive artificial intelligence, data analytics, and overall digital transformation.
“Andrew’s appointment will accelerate our strategic efforts in data analytics, digital innovation and responsible AI,” said Westpac CEO Anthony Miller.
“He’s an outstanding executive and thought leader who has successfully transformed data and digital capabilities in leading financial institutions globally. By integrating our data, digital and AI functions under Andrew’s leadership, we aim to become a truly service-centric organisation, improving the customer experience and empowering our teams.”
The customer and employee experience will be top priority, said Westpac in a statement. McMullan will report directly to Miller.
“Andrew will build on the strong foundations established over the past five years by our CIO Scott Collary. He will work closely with Scott and our executive team as we continue to responsibly leverage data to enrich the customer and employee experience. Andrew’s leadership will also be instrumental in supporting the successful delivery of UNITE,” Miller said.
“I look forward to welcoming Andrew to our executive team.”
Some have labelled the move a “poaching” on Westpac’s behalf, scooping up the executive of a direct competitor.
Joining CBA in July 2016, McMullan was instrumental in driving digital transformation at the major.
He has held an executive position since being appointed the chief analytics officer, which he served from July 2018 to September 2021.
Since September 2021, he has held the role of chief data and analytics officer.
McMullan has built a career in developing and scaling digital, data analytics, and AI platforms. He holds a PhD in statistics from the University of Glasgow.
