Health organisations were again the most targeted sector for cyber intrusions in 2025, with stolen patient data proving too valuable for criminals to ignore. Technology teams now race to pre-empt a new wave of autonomous robots that scan networks for gaps, then move quickly to exploit unprotected medical information.
These tools act at machine speed and can turn even minor configuration errors into major privacy incidents.
Australian regulators report the health sector accounts for 19% of all data breaches lodged with the Office of the Australian Information Commissioner in 2025. That makes 2025 the worst year on record for notified breaches since mandatory reporting began in 2018.
Artificial intelligence has not yet been logged as a primary trigger for incidents, yet its role in automating reconnaissance and exploitation is clearly growing.
Research from the Office of the Australian Information Commissioner shows public sentiment has shifted against unfettered AI use in sensitive areas such as healthcare.
Surveys reveal Australians report low trust in artificial intelligence handling personal information, particularly medical records. An overwhelming majority say they want tighter safeguards and clearer transparency around how these systems collect, analyse and store their data.
Public anxiety sets a high bar for any hospital or clinic rolling out new AI tools in front-line care or back-office operations.
