The OAIC’s Notifiable Data Breaches report for 2024 records a record 1,113 breaches—largely caused by malicious attacks such as phishing, stolen credentials, and ransomware—disproportionately impacting health, finance, and government sectors, with dozens of large incidents (40 affecting >5,000 people and 5 affecting >1 million) and concerns about delayed public-sector notifications and the need for stronger privacy and breach-response measures.
