Defence Security Clearance Sponsorship
Australia’s defence industry is experiencing significant growth, particularly in South Australia, driven by AUKUS, sovereign capability investment, defence infrastructure programs, and long-term national security priorities. As defence primes, SMEs, and government agencies continue to scale operations, demand for suitably qualified and security-cleared professionals is increasing rapidly across engineering, technology, project delivery, operations, and corporate services roles.
Many opportunities across the defence and government sectors require an active Australian Government security clearance. However, candidates often face a common challenge: employers require candidates to already hold a clearance, while candidates typically need sponsorship through employment to commence the process.
To help address this market challenge, Harrison McMillan provides eligible candidates with access to pathways for independent security clearance sponsorship through an accredited DISP Level 3 certified provider delivering Security Clearances as a Service (SCaaS). This pathway allows eligible individuals to commence the security clearance process prior to securing a role, helping position them more competitively within the defence employment market.
How Security Clearance Sponsorship Can Benefit Your Career
- Access opportunities across Australia’s growing defence and government sectors
- Improve eligibility for security-cleared and defence industry roles
- Increase competitiveness within a high-demand candidate market
- Reduce mobilisation and onboarding timeframes for future employers
- Position yourself for long-term career opportunities within defence, government, and critical infrastructure sectors
- Receive guidance and support throughout the security clearance process
Security Clearance Pathways Available
Eligible candidates may be able to access sponsorship pathways for:
- Baseline Security Clearance
- NV1 Security Clearance
- NV2 Security Clearance
