A defence clearance is a government-issued security authorisation required for individuals working with classified information or sensitive systems related to national defence. In Australia, defence clearances are managed through the Australian Government Security Vetting Agency (AGSVA) and are required for personnel employed by government agencies, defence contractors, and organisations supporting national security operations. Defence clearances verify that individuals are trustworthy and suitable to access sensitive government information. The vetting process involves detailed background checks, including identity verification, employment history, financial checks, and assessments of personal associations. Defence clearance levels in Australia include Baseline, Negative Vetting Level 1 (NV1), Negative Vetting Level 2 (NV2), and Top Secret Positive Vetting (TSPV). These clearances are essential for roles involving defence technology, intelligence, cybersecurity operations, and critical national infrastructure protection.

In defence clearance contexts, MyRISK can strengthen the management framework around sensitive roles, projects, systems, and obligations by supporting structured attestations, evidence, exceptions, and reporting. It does not replace formal clearance systems, but it can improve internal oversight and governance around cleared work. This is particularly relevant for defence industry participants needing robust assurance practices.
