It also provides operational functionality for Border Force and Immigration Enforcement. The system has a requirement to 24 hours a day, 7 days a week availability, with updates and enhancements continually delivered to enhance functionality and capabilities. It underpins a range of critical national priorities and a significant amount of continuous improvement work driving strategic outcome delivery from the Caseworking Capability.
The objective is a re-procurement to replace the following two incumbent contracts:
