Medibank Private expects to log up to $45 million in one-off cybercrime expenses this financial year following its cyberattack, which compromised the personal data and health information of nearly 10 million current and former members.

The health insurer’s chief executive, David Koczkar, dubbed the $45 million in non-recurring costs as the “top end” of a range for cyber expenses, while total management expenses were expected to hit about $560 million for the 2023 financial year, he told the Macquarie Australia Conference in Sydney.
