Westpac names new chief data, digital and AI officer

Westpac has announced the appointment of Andrew McMullan (pictured above) as its incoming chief data, digital and AI officer.  

McMullan moves to Westpac from Commonwealth Bank of Australia, where he most recently held the position of chief data and analytics officer.  

At Westpac, he will be responsible for leading the organisation’s data strategy, digital projects and artificial intelligence programs. He will report directly to chief executive Anthony Miller and is set to join the bank in September 2025.  

McMullan will also work closely with current chief information officer Scott Collary, who has helped shape the bank’s technology platforms over the past five years. McMullan is also expected to play a key role in advancing the bank’s UNITE initiative, a major transformation project.  

Andrew’s appointment will accelerate our strategic efforts in data analytics, digital innovation and responsible AI,” Miller said. “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.  

“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.”  

McMullan holds a doctorate in statistics from the University of Glasgow and brings with him global experience in building data and AI frameworks for financial institutions. His work has centred on using technology to support customer outcomes and enhance organisational performance.
