Security Clearances Lapse — Verify Currency for Every Crew Member Before Mobilising to a Defence Site
A marking job at an Osborne defence precinct required 72-hour security clearance for all crew. We submitted clearance applications in advance and received approvals for the full team. On the day of mobilisation, one crew member's clearance was queried at the security gate — it had lapsed by six weeks since the original clearance was issued. The clearance had been valid when issued, but a subsequent review by the defence contractor's security team had flagged an administrative issue that invalidated it.
Security turned the crew member away. We had to source a cleared replacement crew member on the day — which took four hours. The client was understanding but the session was compressed and we finished later than planned.
Defence site security clearances for contractors have expiry dates and can be revoked or flagged after initial issue. Verifying that every crew member's clearance is current — not just that a clearance was issued — is now a pre-mobilisation check for every Osborne and defence precinct job. We confirm currency directly with the client's security coordinator 24 hours before mobilisation.
Osborne is Adelaide's defence and naval industrial precinct — ASC submarine construction and sustainment, BAE Systems, and the naval support businesses on the Port River. DPTI approved. Security clearance currency verification is mandatory pre-mobilisation for every Osborne defence precinct marking job.

Frequently Asked Questions
Yes. Osborne ASC and defence precinct carparks and facilities are part of our Adelaide schedule. Security clearance currency verification for all crew 24 hours before mobilisation. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability insurance. Every Osborne quote includes a site assessment, surface condition report, and fixed pricing. No estimates that change at invoicing. For SafeWork SA improvement notices we can typically assess within 24 hours and deploy within 48-72 hours. Completion comes with photo documentation, a compliance statement, and material specifications. DPTI approved for any road or carpark marking that requires local council or state road authority sign-off.
Clearance duration varies by the specific defence site and the clearance level required. Some site-specific clearances last 12 months, others require annual renewal. National security clearances have longer durations. The key is that clearance status can change after initial issue — administrative reviews, changed circumstances, or system updates can flag a clearance between issue and site visit. For standard Osborne jobs we quote within 48 hours of receiving site plans. Scheduling depends on crew availability and access windows, but most jobs are completed within 5-10 business days of quote acceptance. Urgent WorkSafe notice response can be accelerated to 24-48 hours for assessment and 2-4 days for completion. Call Niel on 0417 460 236 if timing is critical.
We contact the client's security coordinator or base security office directly 24 hours before mobilisation and confirm that each crew member's clearance is current and valid for the specific access level required.
