Deloitte Australia has repaid almost $98,000, or more than 20 per cent, of the $440,000 fee it charged the federal government for a report that had to be reissued due to artificial intelligence-related errors.

The big four consulting firm also instructed the team that produced the report for the Department of Employment and Workplace Relations (DEWR) to undertake additional training on how to responsibly use AI and properly review material produced by the technology.
