What is NV1 Security Clearance?

An NV1 (Negative Vetting Level 1) security clearance allows you to work with certain sensitive government information, specifically up to the SECRET level. It's often required in roles across defence, government, and secure IT environments where information needs to be protected. Many roles with NV1 clearance don't deal directly with top-secret materials but still involve confidential or classified information.

Why Would You Need NV1 Clearance?

If your job involves handling sensitive information or working on government projects, an NV1 clearance proves you can be trusted with that responsibility. This clearance is essential for roles in defence, government departments, and organisations connected to national security, where strict information security is a priority. Having an NV1 clearance shows that you've met specific vetting requirements, making you suitable to work in these environments.

What's Involved in Getting NV1?

The NV1 vetting process, overseen by the Australian Government Security Vetting Agency (AGSVA), includes filling out forms, providing personal background information, and completing several checks. AGSVA reviews your work history, residential addresses, and other details over the past ten years. The goal is to confirm your trustworthiness and minimise any risks to security. You might also be interviewed or have your referees contacted during this process.

How Long Does It Take?

The time to obtain NV1 clearance can range from a few months to over six months, depending on how detailed your background is and how busy AGSVA is. This thorough process means you should plan ahead if you know you'll need an NV1 clearance to avoid project delays.

What Does it Cost?

As of 2023-2024, the AGSVA fee for an NV1 clearance is AUD 1,355 (inclusive of GST). This fee is the responsibility of the applicant and is payable upon clearance approval. Whilst employers may choose to cover this cost for their employees, sponsoring entities do not bear responsibility for clearance fees.

How Long is NV1 Clearance Valid?

An NV1 clearance is generally valid for ten years after which you may need to undergo re-assessment or revalidation. This ensures your eligibility and suitability to handle sensitive information are still current.

What to Expect After You Get Your NV1 Clearance?

Once you're approved, your NV1 clearance allows you to work in roles that require this level of vetting. It's important to maintain the clearance by following reporting requirements if any major life changes occur (such as a move overseas or changes in personal relationships), as these could affect your clearance status.
