Medibank has announced to the ASX the forthcoming retirement of group executive of technology and operations John Goodall.

Goodall, who has served more than six years in the role, is responsible for Medibank’s technology, operations, property, and procurement functions.

Medibank chief executive David Koczkar thanked the outgoing tech and ops chief “for his significant contribution to our business over the past six years” and wished him “well in his retirement”.

Kylie Williamson, currently Medibank’s senior executive – core customer systems, will step in as interim tech & ops head until a permanent replacement for Goodall is found.

Williamson has been with Medibank for nearly eight years, the past four in her current role.

The health insurer, one of Australia’s biggest with more than 3.7 million customers, said it would consider both internal and external candidates for Goodall’s replacement.

Goodall’s retirement comes months after the health insurer suffered an, at the time, ‘unprecedented’ data leak resulting in the loss of nearly half a million records to criminal hackers.

Prior to joining Medibank Goodall served nearly two years as general manager enterprise technology at online gambling company Sportsbet. He was also chief information officer in his final role at GE Capital across a nearly quarter century with the financial services group.

Goodall officially steps down from his role at Medibank in April.
