MBK Security Group provides NV1-cleared security officers for Melbourne CBD government, Defence, research, and critical infrastructure sites. Operating under Victoria Private Security Business Licence Z63-319-71S and across Australia under multiple state Master Licences, our cleared-officer roster is verified against AGSVA records before each assignment and operates in alignment with client security plans and the Protective Security Policy Framework (PSPF).
Melbourne sits in the second tier of Australian NV1 demand — behind Canberra, Sydney, and the AUKUS-anchored Perth and Adelaide markets — but the city has its own substantial cleared-personnel footprint. DSTG Fishermans Bend is the largest Defence Science and Technology Group site in the country. RAAF Williams (Laverton and Point Cook) hosts Air Force training and corporate functions. Defence Plaza Melbourne in the CBD anchors a significant Defence headquarters tenancy. Add the Commonwealth and Victorian state government tenancies in the CBD towers, the Port Melbourne and Tullamarine critical infrastructure, and the Defence Industry corridor at Port Melbourne — and Melbourne earns its own dedicated NV1 location page.
If you’re a Defence prime, a Defence Industry contractor, a Commonwealth or Victorian government facility manager, a critical infrastructure operator, a data centre operator, or a corporate occupier with a Melbourne site that requires personnel cleared to Negative Vetting Level 1, this page is for you.
Where NV1 clearance is required in Melbourne
Melbourne NV1 demand concentrates around six distinct facility types and precincts:
- DSTG Fishermans Bend. The largest Defence Science and Technology Group site in Australia, focused on aerospace systems, materials and structures, weapons effects, and human performance research. Cleared-personnel requirements at Fishermans Bend are among the most stringent in Australian Defence research, with most roles requiring NV1 as a baseline and many requiring NV2 or PV.
- RAAF Williams (Laverton and Point Cook). Home of Air Force Training Group and a number of Defence corporate and command functions. Point Cook is the historical and ceremonial home of the RAAF and houses the RAAF Museum and academic programmes. NV1 is a baseline expectation for guarded perimeter, gatehouse, and protected-zone work at both bases.
- Defence Plaza Melbourne and CBD Defence tenancies. The Defence Plaza building at 661 Bourke Street is the primary Department of Defence tenancy in Melbourne, hosting personnel from across Defence corporate, capability acquisition, and intelligence functions. Surrounding CBD towers house additional Defence and Defence Industry tenants.
- Commonwealth government tenancies in the CBD. Substantial Commonwealth presence including ATO, Department of Home Affairs Melbourne offices, Services Australia, AFP Melbourne operations, ASIO Melbourne operations, ASIC, APRA, and the Reserve Bank of Australia Melbourne offices. Many have protected-zone requirements.
- Victorian state government precincts. The Treasury and Treasury Place precinct, the Old Treasury Building, the Department of Premier and Cabinet, Victoria Police HQ at Spencer Street, and the broader 1 Treasury Place / 1 Macarthur Street government cluster — handling protected-information environments at executive and incident-response levels.
- Critical infrastructure under SOCI Act 2018. Port of Melbourne operations, Melbourne Airport (Tullamarine) and Avalon Airport precincts, the AusNet and CitiPower transmission infrastructure, telecommunications carrier facilities, and major water infrastructure — falling under Critical Infrastructure Risk Management Program (CIRMP) obligations.
- Data centre clusters. Tier III/IV data centres at Tullamarine, Port Melbourne, and Derrimut — many handling protected and PROTECTED:CABINET workloads for Commonwealth and Victorian government clients. Melbourne is one of Australia’s three major data centre markets alongside Sydney and Canberra.
- Higher education and research with Defence-funded programs. Including the University of Melbourne (Parkville), Monash University (Clayton and Caulfield), RMIT (CBD), Swinburne (Hawthorn), and Defence Innovation Hub-aligned research environments.
What our NV1 officers do on Melbourne sites
Cleared work in Melbourne spans Defence research, Defence base perimeter and access control, Commonwealth and Victorian government departmental access control, and Defence Industry executive-floor security. Our NV1 officers perform tasks that require active vetting, disciplined SOPs, and government-grade reporting:
- Access control and identity verification — pass issuance, contractor induction, visitor vetting, badging, and permit-to-work checks at controlled entry points (especially DSTG Fishermans Bend, RAAF Williams, and Defence Plaza Melbourne)
- Gatehouse and secure reception — staffed entry points, mail and delivery screening, vehicle inspection at protected-zone perimeters
- Patrols of protected and CABINET-classified areas — foot patrols inside controlled perimeters, CCTV monitoring, and incident detection in line with site security plans
- Alarm response inside cleared zones — escalation protocols and coordinated response with Departmental Security Advisors, Defence Security Officers, base security commanders, and Victoria Police where relevant
- Search and screening — bag and vehicle inspection, x-ray and metal detection where required, screening as per site-specific Standard Operating Procedures
- Incident management and reporting — shift logs, evidence preservation, witness statements, and liaison with sponsoring agencies
- Event security at protected venues — Ministerial events, departmental functions, AUKUS partner visits to DSTG, sensitive corporate events at Defence Industry primes — where cleared personnel are required for crowd management at controlled venues
- Research environment security — laboratory access management, IP-protected environment security, and after-hours research patrols (particularly relevant at DSTG and Defence-funded university research programmes)
Compliance and governance
Melbourne Defence and government clients apply demanding governance frameworks, with DSTG Fishermans Bend in particular operating to elevated controls. Our operating standards align to:
- AGSVA clearance verification — every assigned officer’s NV1 status is verified during onboarding and re-verified before each assignment.
- Protective Security Policy Framework (PSPF) alignment — our SOPs align to the four PSPF outcomes for Commonwealth and Defence clients.
- Defence Industry Security Program (DISP) alignment — for engagements with Defence primes and DISP-member organisations in Melbourne, we operate to DISP personnel, physical, ICT, and governance standards.
- Victorian Protective Data Security Standards (VPDSS) — for Victorian state government clients, where state-level protected-information protocols apply alongside or instead of PSPF. The VPDSS framework administered by OVIC (Office of the Victorian Information Commissioner) governs protected-information handling across Victorian agencies.
- Site security plans and DSA-approved procedures — every Melbourne deployment operates to the client’s site security plan.
- SOCI Act compliance for critical infrastructure clients — including alignment to CIRMP requirements for Port of Melbourne, energy, and telecommunications sector clients.
- WHS and fitness for duty — site-specific inductions, drug and alcohol testing where required, and ongoing fitness-for-duty monitoring.
- Reporting and audit trail — shift logs, handover notes, incident reports, and audit-ready records delivered as per client cadence.
- VIC Private Security Business Licence Z63-319-71S — every officer is also licensed under Victorian security legislation, in addition to holding AGSVA clearance.
How we resource NV1 roles in Melbourne
Melbourne is a substantial market for cleared work, with steady demand from DSTG, RAAF Williams, Defence Plaza, and the Commonwealth and Victorian government tenancies. We resource Melbourne NV1 work through three channels:
- Existing NV1 pool — we maintain a roster of NV1-cleared officers with capacity for VIC deployments, including officers familiar with DSTG research environment protocols, RAAF Williams base procedures, and Victorian government tenancy requirements.
- Client-sponsored clearances — when new sponsorship is needed for a specific Melbourne site, we coordinate with the sponsoring agency, prime contractor, or DSA to manage the AGSVA process. This is common for new Defence Industry contracts and DSTG-aligned research engagements.
- Surge capacity and relief — trained relief officers maintain coverage during leave, training cycles, or surge requirements (such as DSTG technology demonstrations, Air Force ceremonial events at Point Cook, or major Defence Industry conferences).
Each Melbourne NV1 deployment includes a named site supervisor and a duty manager accountable for shift-by-shift compliance.
Why MBK for NV1 work in Melbourne
- VIC Private Security Business Licence Z63-319-71S. Active and in good standing — every officer is licensed under Victorian security legislation in addition to holding AGSVA clearance.
- Multi-state licensing. Plus active licences in NSW, ACT, QLD, WA, SA, TAS, and NT — useful when a Melbourne Defence Industry contract has interstate components, which is common given Australia’s distributed Defence Industry footprint.
- Forty-plus years of operational continuity. Founded in 1984. For Defence research and government cleared work, supplier longevity and stability are themselves procurement criteria.
- Integrated capability. NV1 guarding can be combined with mobile patrols, alarm monitoring, CCTV, and facility maintenance — all under one accountable provider, simplifying procurement.
- Audited management systems. ISO 9001 (quality), ISO 14001 (environment), and ISO 45001 (work health and safety) certified. ASIAL Silver member.
- Disciplined supervision model. Site supervisors and duty managers, not unsupervised solo guards. Critical for cleared work where compliance is the product — and especially critical at research environments where IP protection sits alongside personnel security.
- National Defence research alignment. Because we operate across all eight states and territories, we can support DSTG and Defence research clients with multi-site footprints — DSTG Fishermans Bend (Melbourne), DSTG Edinburgh (Adelaide), DSTG Stirling West (Sydney), DSTG Scottsdale (Tasmania) — with consistent compliance frameworks.

How NV1 pricing works for Melbourne contracts
NV1 cleared officers in Melbourne attract a premium over standard licensed guards because of the clearance investment, vetting maintenance, and operational discipline required for cleared work. Melbourne sits within the Victorian metropolitan award envelope. Pricing depends on:
- Clearance level required — NV1, NV2, or PV. NV1 is above Baseline and below NV2/PV; pricing scales with clearance. DSTG research work and certain Defence Plaza roles often require NV2 or PV.
- Hours of cover and shift pattern — 24/7 base perimeter operations vs business-hours-only departmental reception differ significantly.
- Site risk profile and SOP complexity — base gatehouse vs DSTG laboratory access vs CABINET-area patrols vs Defence Industry executive-floor coverage.
- Sponsorship arrangements — whether MBK supplies pre-cleared officers from existing pool, or whether the client/agency sponsors new clearances.
- DISP alignment requirements — Defence Industry contracts increasingly specify DISP-aligned controls beyond standard NV1 requirements.
- VPDSS alignment for Victorian government clients — Victorian state agency contracts apply VPDSS-specific reporting and control requirements.
- Reporting cadence — daily/weekly/monthly governance reporting requirements, integration with client GRC platforms.
- Procurement vehicle — pricing differs across direct engagement, panel arrangements, prime contractor sub-engagements, and managed service contracts.

Frequently Asked Questions
What is an NV1 clearance and why does it matter for Melbourne work?
NV1 — Negative Vetting Level 1 — is a security clearance issued by the Australian Government Security Vetting Agency (AGSVA). It allows the holder to access information classified up to PROTECTED. In Melbourne, NV1 is required for most guarding work at DSTG Fishermans Bend, RAAF Williams (Laverton and Point Cook), Defence Plaza Melbourne, Commonwealth and Victorian government tenancies handling protected information, and at data centres and SOCI-regulated critical infrastructure. Many DSTG roles require NV2 or PV rather than NV1.
Does MBK service DSTG research environments at Fishermans Bend?
Yes. DSTG Fishermans Bend is the largest DSTG site in Australia, with cleared environment requirements for aerospace systems, materials, weapons effects, and human performance research. We support NV1 and higher cleared-personnel guarding requirements at research sites where laboratory access, IP protection, and protected-information handling are core operating concerns. Many DSTG roles require NV2 or PV — we work through the same sponsorship and verification model for higher clearances.
Does MBK provide cleared guards for RAAF Williams (Laverton and Point Cook)?
Yes. Officers assigned to RAAF Williams sites complete site-specific inductions covering the relevant security plan, base orders, and SOPs. Where the site requires familiarity with Air Force base access protocols, training operations, or specific Defence Industry Security Program (DISP) requirements, we assign officers with prior experience and complete the required briefings before deployment.
Can MBK sponsor an NV1 clearance for a Melbourne site?
Clearances are sponsored by eligible Commonwealth entities or approved contractors — they cannot be sponsored by a security provider on its own. What we do is work with your sponsoring agency, prime contractor, or DSA to coordinate the AGSVA process for officers we onboard for your site, manage the rostering once sponsorship is in place, and handle clearance-currency monitoring throughout the engagement.
How does VPDSS apply to Melbourne security contracts?
The Victorian Protective Data Security Standards (VPDSS) are Victoria’s state-level information security framework, administered by the Office of the Victorian Information Commissioner (OVIC). For Victorian state government clients, VPDSS-aligned controls apply alongside or instead of the Commonwealth PSPF, and reporting requirements differ. Our SOPs accommodate both frameworks depending on the client’s tenancy and information classification environment.
How fast can MBK provide NV1 officers in Melbourne?
For sites where MBK has existing cleared officers in the VIC pool, we can typically commence within 5-10 business days from contract signing — including site induction, security plan briefing, and roster confirmation. For sites requiring new client-sponsored clearances, the timeline depends on AGSVA processing times (typically 6-12 months for new NV1 clearances).
Does MBK work with DISP-member organisations in Melbourne?
Yes. The Defence Industry Security Program (DISP) is the Defence vetting framework for industry suppliers. Where a Melbourne client engagement requires DISP-aligned controls — for personnel, physical, ICT, or governance — we work to those standards as part of our SOPs.
What’s different about NV1 work in Melbourne vs other capitals?
The clearance is the same. The work mix differs. Melbourne is unique among the capitals for the dominance of Defence research (DSTG Fishermans Bend) and Air Force training/corporate functions (RAAF Williams). Canberra is dominated by Commonwealth HQ work; Sydney by RAN, financial-sector, and corporate; Perth and Adelaide by AUKUS sustainment and construction respectively; Brisbane by ADF operational bases and AUKUS supply chain. Melbourne adds a significant research and aerospace component to the picture.
