A security clearance is an official authorisation allowing individuals to access classified information. It’s necessary to ensure that sensitive information is only accessible to those who are trustworthy and have a legitimate need to know.

In Australia, the primary levels of security clearance are Baseline, NV1 (Negative Vetting Level 1), NV2 (Negative Vetting Level 2), and TSPV (Top Secret Positive Vetting). Each level corresponds to the degree of sensitivity of the information to which the holder has access.

The vetting process includes a thorough review of personal details, employment history, financial records, criminal history, and potentially interviews with associates. The goal is to assess the individual’s reliability and trustworthiness.

Security clearances are generally only available to Australian citizens. In exceptional cases, permanent residents may be eligible if sponsored by a government agency, but this is rare.

Once granted, security clearances must be maintained through adherence to security protocols and periodic revalidation. Any changes in personal circumstances must be reported immediately.

Clearances may be revoked due to criminal activity, financial instability, unauthorised disclosures, or failure to comply with security protocols. Regular reviews ensure that clearance holders continue to meet the necessary criteria.

Security clearances are not transferable between countries. If you need to work with classified information in another country, you will need to apply for a new clearance under that country's vetting process.

Yes, higher clearance levels such as NV1, NV2, and TSPV require more extensive vetting processes, including deeper background checks and, in some cases, psychological assessments.

AGSVA is the central agency responsible for conducting security clearances across most Australian government departments and some private sector organisations involved in national security.

Your employer will inform you if your role requires a security clearance. It is typically necessary for positions that involve access to classified or sensitive information within government or defence sectors.

Baseline Security Clearance is the entry-level clearance required for individuals needing access to classified information up to the 'Protected' level.

NV1 (Negative Vetting Level 1) Security Clearance allows access to classified information at the 'Secret' level. It requires a more thorough vetting process than Baseline Clearance.

NV2 (Negative Vetting Level 2) Security Clearance is required for access to highly sensitive classified information at the 'Top Secret' level. This level involves an even more comprehensive vetting process.

TSPV (Top Secret Positive Vetting) is the highest level of security clearance, granting access to information classified as 'Top Secret' or higher. It includes extensive background checks, psychological assessments, and detailed interviews.

Security clearances typically need to be revalidated every five years, although the specific duration may vary based on the clearance level and other factors.
