New South Wales: a former staff member or contractor of the NSW Reconstruction Authority uploaded a spreadsheet of Resilient Homes Program applicant data to ChatGPT; the Authority confirmed 2031 people had data uploaded
The NSW Reconstruction Authority says that between 12 and 15 March 2025 a former temporary staff member (earlier described as a former contractor) uploaded an Excel spreadsheet with 10 columns and more than 12,000 rows from the Northern Rivers Resilient Homes Program to ChatGPT, an AI tool the Authority had not authorised. The Authority first disclosed the breach on 6 October 2025 as affecting up to 3000 people and later confirmed through external forensic analysis that 2031 people had data uploaded, including names, contact details, addresses, dates of birth and sensitive personal information (an earlier notice also listed health information). It reports no evidence that the data was made public or accessed by a third party, and that no driver licence, Medicare, passport or Tax File Numbers were included. The Authority apologised, offered ID Support NSW assistance and committed to compensate reasonable document replacement costs. One participant told the ABC they were concerned. No misuse of the data is reported.
