The Defence Industry Security Program (DISP) is the gateway to working with the Australian Department of Defence on contracts that involve access to classified or security-sensitive information, assets, or capabilities. Every organisation that wants to participate in the Australian defence supply chain at anything above the most basic level needs DISP membership — but choosing the right level is a decision that many organisations get wrong, in both directions.
Over-scoping — applying for a higher DISP level than your contracts require — wastes time, money, and management attention on security controls you do not need. Under-scoping — applying for too low a level — means you hit a ceiling the moment a contract requires access to PROTECTED information, forcing an upgrade process that can take months.
This article provides a practical comparison of DISP Level 1 and Level 2 (the two levels relevant to the vast majority of defence industry participants), explains the security requirements at each level, and helps you determine which level aligns with your actual contract needs.
Understanding the DISP Level Structure
The DISP operates across four membership levels, each corresponding to increasingly sensitive activities and information classifications:
- Level 1 — Access to OFFICIAL and OFFICIAL:Sensitive information. The entry point for most defence suppliers.
- Level 2 — Access to PROTECTED information. Required for contracts involving classified material at the PROTECTED level.
- Level 3 — Access to SECRET information. Significantly more demanding security requirements, including specific physical security zones.
- Level 4 — Access to TOP SECRET information. The highest level, with the most stringent requirements across all security domains.
In practice, Level 1 and Level 2 cover the vast majority of defence industry participants. Level 3 and Level 4 are relevant to a smaller number of entities working on highly sensitive programs. This article focuses on the Level 1 vs Level 2 decision, which is the most common question I encounter when advising defence industry clients.
Important clarification: DISP membership levels are not a progression. You do not need Level 1 before applying for Level 2. You apply for the level that matches your contract requirements. If your contracts require PROTECTED access from day one, apply for Level 2 directly.
