Organisations supporting the Australian Defence Force (ADF), defence contractors, and government agencies across Australia are under more pressure than ever. Inventory needs to be accurate. Access needs to be controlled. And every item needs to be traceable — from the moment it arrives to the moment it leaves.
At the same time, rising warehouse costs across Sydney and the broader NSW corridor, combined with ongoing labour shortages in logistics roles, are making traditional storage methods harder to justify. Facilities that once relied on open shelving, static racking, and manual picking are finding it increasingly difficult to keep pace.
Globally, leading defence organisations — including the U.S. Defense Logistics Agency (DLA), which has deployed automated warehouse technologies across 19 of its 24 distribution sites — are investing heavily in inventory automation to improve operational resilience and visibility. Australian defence and logistics facilities are following suit.
Automated storage for defence and logistics is changing the equation. Technologies like Vertical Carousels and Vertical Lift Modules (VLMs) give organisations a practical way to improve warehouse security, increase throughput, and maintain the kind of inventory control that defence and government environments require. This guide explores how these systems operate, the challenges they address, and the key factors to consider when selecting the right solution for your facility.
Defence agencies, government organisations, and contractors working within the defence sector must manage inventory under far stricter security, compliance, and accountability standards than those typically found in commercial warehousing environments.
Open access to inventory is not an option. Every transaction needs to be documented. And the consequences of a missing item — whether a spare part, a piece of tactical equipment, or a controlled document — can be significant.
Defence challenges tend to centre on weapons and equipment control, sensitive inventory management, and chain-of-custody documentation. Audit readiness is not a periodic exercise — it is a constant requirement. Facilities need to know who accessed what, when they accessed it, and why. Security compliance is built into the operational standard.
Logistics challenges are different but equally demanding. High SKU counts, rapid order fulfilment cycles, and the need for real-time inventory visibility create a constant operational load. Labour shortages make manual systems harder to sustain. When a picker spends time walking aisles searching for items, that is time the operation cannot afford. In major logistics hubs such as Western Sydney — including the Erskine Park, Marsden Park, and Eastern Creek precincts — warehouse operators are increasingly turning to automation to maintain throughput without expanding their footprint.
Government requirements add another layer. Traceability, controlled access, compliance reporting, and asset accountability are not optional — they are often written into procurement contracts and audit frameworks. Facilities need to demonstrate that they can account for every item at any point.
Traditional racking systems struggle to meet these demands. Open shelving offers no access control. Manual systems create audit gaps. And as inventory volumes grow, the complexity of managing a conventional warehouse increases faster than the capacity to handle it.
Automated storage systems address these gaps directly. For organisations exploring automated storage for defence and government environments, the case is not just about efficiency — it is about meeting the operational and compliance standards that these settings require.
One of the most important advantages of automated storage systems is what happens before the inventory moves. Access to the system itself is controlled at the user level, and every interaction is recorded.
Vertical Carousels and VLMs operate with user login permissions, meaning only authorised personnel can retrieve inventory. Role-based access allows facility managers to restrict which users can access which items. Sensitive inventory can be isolated within secure storage zones, with retrieval only possible by users who have been explicitly granted permission for that category.
This is a meaningful improvement over open shelving or conventional racking, where physical presence in a bay is often the only barrier to access. In a defence or government context, that kind of exposure is not acceptable.
For organisations requiring detailed guidance on security configuration within automated storage for defence and government settings, VCA can advise on access tier structures suited to your inventory profile.
Each inventory transaction is automatically recorded, capturing both the exact time of the activity and the identity of the authorised user who performed it.
This creates a complete transaction record without any manual input from the operator. Compliance reporting becomes a matter of pulling data rather than reconstructing it from paper-based records.
For procurement teams and defence logistics officers preparing for audits, this is a significant operational advantage. The data is already there. It is accurate. And it covers every transaction, not just the ones someone thought to record.
Global providers such as Kardex — one of the most established suppliers of automated storage for military environments — build audit trail functionality as a core feature of their defence-grade systems, reflecting how central traceability has become to defence storage compliance worldwide.
Automated storage systems maintain live stock records integrated with the inventory management software. When an item is retrieved, the system updates immediately. This eliminates the inventory discrepancies that tend to build up in manual environments over time, and it gives managers an accurate picture of what is on hand at any point.
For facilities managing large volumes of spare parts, tools, electronics, or sensitive documentation, this kind of visibility is essential. It supports both day-to-day operations and the broader compliance requirements that defence and government facilities must meet.
The goods-to-person model means inventory is delivered directly to the operator at a fixed picking station, rather than the operator walking into a storage area to retrieve it. This is important not just for efficiency but for security. Operators interact with and manage the system through a designated control interface. They do not enter a storage zone, and they do not have line-of-sight access to items they are not authorised to retrieve.
This approach is a practical way to enforce access boundaries without relying entirely on physical barriers or constant supervision.
Security and access control matter in defence and government environments. But in distribution centres and logistics operations across NSW and the broader Australian supply chain, throughput is the metric that drives everything else. Automated storage systems deliver on that front as well.
In a conventional warehouse, a significant proportion of an operator’s shift is spent walking — from one bay to the next, up and down aisles, searching for items across a large floor area. Studies across the industry consistently show that travel time accounts for more than half of a picker’s working time in manual operations.
Goods-to-person systems eliminate most of that travel. The operator stays at a fixed station, and the system delivers each item. Pick cycles are faster, and operator focus is concentrated on the actual picking task rather than navigation.
For Sydney distribution centres and NSW logistics hubs, where labour costs are high and floor space is expensive, the gains from reducing travel time directly improve the economics of the operation. Learn more about the throughput advantages of automated storage in distribution centres.
The performance gains from automated picking systems are substantial. Shuttle-based automated storage systems can achieve pick rates of up to 700 lines per hour — a throughput level that would require significantly more operators and floor space in a conventional warehouse. Productivity improvements of up to two-thirds are achievable, depending on the operation and the inventory profile. In some e-commerce and defence supply chain applications, average pick times have been reduced by as much as 60% following ASRS implementation.
Automated systems integrate with barcode verification and inventory software, which means picks are guided and confirmed rather than relying on operator memory or manual checking. This reduces picking errors significantly — and in defence or government supply chains, where the wrong item being dispatched can have serious consequences, that accuracy matters.
Guided picking also reduces the training burden for new operators. The system directs the pick; the operator executes it. This is an advantage in environments where staff turnover is a factor or where rapid onboarding is needed.
Fewer operators can manage larger inventory volumes when the system is doing the retrieval work. This is particularly relevant in the current Australian labour market, where logistics workforce shortages have made it difficult for many facilities to maintain adequate staffing levels. Automated storage helps facilities maintain throughput even when headcount is constrained — a critical resilience factor for defence supply chains where operational continuity cannot be compromised.

Not all inventory is the same. In defence and government environments, some items require a higher level of control than others. Automated storage systems can be configured to reflect those distinctions.
Vertical Carousels and VLMs are suitable for a wide range of inventory types relevant to defence and logistics environments. Spare parts and tools are common applications, but systems also handle tactical gear, electronic components, sensitive documentation, controlled government assets, and defence equipment of various sizes and weights. The enclosed storage design means items are protected from dust, tampering, and unauthorised handling while they are in the system.
In practice, defence technology providers have demonstrated the scale of what is possible: a 2023 SSI SCHAEFER deployment for a European defence technology organisation stored 130,000 individual items across 45,000 ESD-compatible containers — all integrated directly with SAP S/4HANA and designed to meet strict cybersecurity and data protection requirements. Projects of this scale confirm that automated storage systems can handle the complexity and sensitivity of real-world defence inventory management.
User authentication is built into the system. Access permissions can be configured at the item category level, so restricted inventory is only accessible to personnel with the appropriate clearance. The enclosed design of VLMs means items are not visible or accessible outside of an authorised retrieval cycle.
This kind of configuration is straightforward to document for procurement purposes and straightforward to audit. For defence contractors and government agencies preparing for compliance reviews, that auditability is a practical advantage.
Modern automated storage systems are designed to integrate with Enterprise Resource Planning (ERP) systems and Warehouse Management Systems (WMS). This means the automated storage unit does not sit in isolation — it becomes part of the broader inventory management infrastructure. Procurement software, supply chain visibility tools, and reporting platforms can all draw on the same data.
For facilities that are already running a WMS or ERP platform, integration is typically a key evaluation criterion. VCA provides inventory management software designed to work with existing systems, which reduces the complexity of bringing automated storage into an established technology environment.
One of the practical advantages of modular automated storage systems is that they can grow without requiring a facility to relocate or undergo major reconstruction. Additional VLM columns or Vertical Carousel units can be added as inventory volumes increase, using existing vertical space more intensively rather than expanding the footprint. For defence contractors and government agencies working within fixed site constraints, this scalability is an important long-term consideration.

The adoption of automated storage across Australian defence, government, and logistics facilities reflects a straightforward cost-benefit calculation. The problems these systems solve are real, the benefits are measurable, and the operational context makes the investment case compelling.
Space optimisation is often the most immediate driver. Vertical Lift Modules can reduce floor space requirements by up to 90% compared with conventional storage layouts — a significant result in high-cost warehouse markets like Western Sydney and the NSW industrial corridor, where expanding a facility footprint is expensive and often impractical. Organisations can repurpose recovered floor space or simply reduce the total warehouse area required to store the same inventory volume.
Operational efficiency follows naturally. Faster retrieval, reduced travel time, and higher pick rates mean the same operation produces more output with less labour input. Australian operations that have implemented automated storage systems typically see cost savings of 20–40% and return on investment within two to five years.
Inventory accuracy improves because the system tracks every transaction automatically. Manual stocktakes and paper-based records are replaced by live data. Discrepancies that would previously accumulate over weeks or months are caught immediately, and the overall accuracy of stock records improves substantially.
Workplace safety is an often-overlooked benefit. Operators no longer need to climb ladders, reach for high shelves, or manually lift heavy items from awkward positions. The goods-to-person model presents inventory at an ergonomic working height. This reduces manual handling injuries and supports compliance with Australian workplace safety standards.
Compliance support is built into the operation. Audit trails, access logs, and real-time inventory records give defence and government facilities the documentation infrastructure they need to meet their reporting obligations without additional manual effort. For organisations working within ADF supply chain frameworks or NSW government procurement requirements, this built-in compliance capability is a direct operational advantage.

The case for automated storage for defence and logistics comes down to operational reality. Traditional storage systems were not designed for the security requirements, throughput demands, or compliance obligations that modern defence, government, and logistics facilities face. Open shelving has no access control. Manual picking creates errors and gaps in documentation. And conventional racking uses only a fraction of the vertical space available.
Vertical Carousels and VLMs provide a practical solution to these challenges, delivering measurable improvements in efficiency, accuracy, and space utilisation. With floor space savings of up to 90%, pick rates of up to 700 lines per hour, and cost savings of 20–40% post-deployment, these systems deliver results that are supported by real-world defence and logistics applications globally — including the U.S. Defense Logistics Agency’s multi-site WMS rollout and SSI SCHAEFER’s rapid defence technology deployment in Europe.
For Australian organisations — whether supporting ADF supply chains, managing NSW government assets, or running high-volume distribution centres in Western Sydney — automated storage provides the access control, audit trails, and throughput performance that today’s operational environment demands.
