Staff experimentation with ChatGPT

Australia's Home Affairs department suspended ChatGPT access after staff experimentation raised information security concerns

Scaled backPress reporting

Problem

Home Affairs allowed staff to explore ChatGPT's potential for research and technical troubleshooting. The tool had been available in some circumstances from November 2022.

Approach

Staff experimented with technical research and coding questions before the department blocked network access on 17 May 2023. Secretary Mike Pezzullo said individual use without safeguards did not meet the department's security requirements, and access thereafter required a business case and approval. A questionnaire used to reconstruct earlier use drew criticism from Senator David Shoebridge over record keeping. The department said it found no evidence of departmental or classified information being submitted, formal decisions being made with ChatGPT, or generated code being uploaded into departmental systems.

Results

No published figures

Takeaway

Access preceded a requirement for individual experiments to receive specific approval. The department later relied on staff recollections to explain earlier use, while disputing that those experiments had exposed protected information or affected formal decisions.
