The Robodebt scheme, formally Online Compliance Intervention (OCI), was a method of automated debt recovery employed by Services Australia as part of its Centrelink payment compliance program. Put in place in July 2016 and announced to the public in December of the same year, the scheme aimed to replace the formerly manual system of calculating overpayments and issuing debt notices to welfare recipients with an automated data-matching system that compared Centrelink records with averaged income data from the Australian Taxation Office.
