  • •Government agencies took an average of 108 days to report breaches, compared to three days for private companies.
  • •There has been a 69% increase in reported data breaches from 2022 to mid-2026.
  • •Government agencies have become the third-largest source of data breaches in Australia.

An analysis by Adaca reveals that Australian government agencies are significantly slower than private companies in reporting data breaches, averaging 108 days compared to just three days for private firms. The report, based on 4,769 notifications to the Office of the Australian Information Commissioner (OAIC) from 2022 to mid-2026, shows a 69% increase in reported breaches. Government agencies have become the third-largest source of breaches, with 399 incidents reported since 2022. Despite some improvements in reporting times in 2026, the public sector's lag in adopting AI-powered detection systems raises concerns about its ability to manage data security effectively. The findings highlight a disparity in breach reporting between public and private sectors, with calls for urgent reforms to enhance government cybersecurity capabilities.
