Origin Energy cybersecurity breach affecting nearly a million Australians in July 2026

By Updated 24 August 20263 articles from 2 independent sources

Consensus Summary

Origin Energy experienced a major cybersecurity breach in July that exposed personal data of nearly a million Australians, including names, addresses, dates of birth, and financial details for some customers. The breach was traced to a call centre in Manila, Philippines, linked to a former Accenture employee who allegedly attempted to extort the company. Authorities confirmed the incident remains under investigation, with Origin Energy collaborating with law enforcement. The breach follows a series of high-profile cyber incidents in Australia, including major hacks at Qantas in 2025 and Optus and Medibank in 2022. While the company has completed its review of affected data and is notifying customers, it continues to urge vigilance against scams. The breach also highlighted vulnerabilities in third-party call centre operations, with Accenture involved in managing Origin’s customer service. Both ABC and 7NEWS agree on the scale of the breach and the involvement of a former employee, though details on initial reporting and specific timelines vary slightly.
