Warehouse safety in Australia sits under some of the strictest workplace regulations in the country. Most operators have invested heavily in the obvious controls: forklift training, racking inspections, PPE programs, emergency procedures, and lone worker policies. What gets missed in most WHS audits is the layer underneath all of it. If your workers can't get a reliable mobile signal inside the warehouse, every other safety system you've built becomes harder to execute when something goes wrong.
This article covers warehouse safety best practices in line with Australian WHS obligations, then looks at the connectivity issue that quietly undermines them.
Warehouse operations sit within the model Work Health and Safety Act 2011, adopted by most Australian states and territories. Victoria operates under its own Occupational Health and Safety Act 2004, but the core obligations are broadly similar.
Under the WHS framework, a Person Conducting a Business or Undertaking (PCBU) has a primary duty of care to ensure the health and safety of workers, so far as is reasonably practicable. For warehouse operators, this duty extends across the full operational footprint, covering the floor, the racking, the loading docks, cold storage zones, and any yard or external work area.
Safe Work Australia consistently identifies the transport, postal and warehousing sector as one of the higher-risk industries for serious work-related injuries. Forklift incidents, falls from height, manual handling injuries, and racking failures remain the most common causes of harm. Each is well understood, and each is the focus of significant compliance attention.
A strong WHS program in a warehouse environment typically covers the following areas.
That last point is where the connectivity issue begins to surface. Lone worker monitoring depends entirely on the worker being reachable.
Warehouses are some of the most signal-hostile environments in commercial Australia. Several factors compound to create coverage problems:
The result is predictable. Workers report patchy coverage, dropped calls in specific zones, and stretches of the warehouse where nothing works at all. Most operators treat this as a productivity issue and accept it as a cost of working in a large industrial building.
The problem is that the same coverage gaps that frustrate stocktakes also break safety systems.
When a forklift operator is trapped under a fallen load in an aisle with no signal, they cannot call 000. When a lone worker in cold storage triggers a duress alarm, the alarm does not transmit. When wardens need to coordinate an evacuation across a 20,000 square metre site, push-to-talk drops out. When a connected wearable detects a fall and tries to alert a supervisor, the alert fails. When an injured worker tries to call for help, they have to physically travel through the building to find a signal, losing time that may matter.
None of these failures show up in a standard WHS audit, but each one represents a control that has been quietly compromised.
The intersection of coverage and compliance is increasingly scrutinised after incidents. When SafeWork inspectors investigate a serious workplace event, they look at the controls in place at the time. A safety app that did not transmit because coverage was unavailable is functionally equivalent to no app at all. A lone worker check-in system that cannot reach the worker provides no protection.
The PCBU's duty of care under the WHS Act requires controls to be effective in practice, so far as is reasonably practicable. Documented safety systems that depend on mobile connectivity need that connectivity to exist throughout the workplace.
This is becoming particularly relevant for operators using lone worker monitoring platforms, mobile-based duress alarms, IoT safety sensors, and connected PPE. Each of these technologies assumes a working mobile signal. Without one, the technology is decorative.
In-building coverage (IBC) is the industry term for engineered systems that deliver a reliable mobile signal throughout a building. For warehouses, the two most common solutions are:
ACMA compliance is critical here. Australia has strict rules under the Radiocommunications Act about the use of mobile signal boosters, and unapproved devices carry significant penalties for both the user and the supplier. Many warehouses unknowingly run non-compliant equipment purchased online, which exposes the business to enforcement risk on top of the underlying coverage problem.
A properly designed IBC solution begins with an on-site RF assessment. A certified engineer measures signal conditions across the warehouse, identifies dead zones, assesses how building materials and racking layout affect coverage, and designs a system around what they find. After installation, performance is verified across the site before handover.
In practice, a well-designed IBC system delivers:
That last point matters. Coverage that has been engineered, tested, and documented can be evidenced to regulators. Coverage that exists by accident cannot.
Yes. Any safety control that depends on mobile connectivity becomes ineffective in coverage dead zones. The WHS Act requires controls to be effective in practice, which includes the communications infrastructure they rely on.
Wi-Fi calling can fill some gaps, but it depends on uninterrupted Wi-Fi coverage and isn't supported by every device or carrier. It also does not solve emergency calls from devices that have lost both signal and Wi-Fi connection. For most warehouses, mobile coverage remains the primary requirement, with Wi-Fi as a complementary layer.
Only ACMA-approved repeaters supplied by a carrier-authorised reseller are legal. Devices purchased online without ACMA approval are illegal to use, and penalties under the Radiocommunications Act apply to both users and suppliers.
It depends on the size, layout, and construction of the building. A single CEL-FI unit may cover a small warehouse, while a larger facility typically requires multiple units or a DAS. An RF assessment determines what's needed.
Most warehouse installations are completed within a few days, depending on system complexity. Site assessment, design, and ACMA approvals add some lead time before installation begins.
Manual handling injuries remain the leading cause of workers' compensation claims in the warehousing sector, followed by being hit by moving objects, falls, and incidents involving forklifts and mobile plant. These are also the categories that regulators focus on during compliance audits.
A formal review is recommended at least annually, after any serious incident or near-miss, after layout or equipment changes, and whenever new hazards are introduced. Lone worker procedures and emergency communications protocols should be tested more frequently than the broader WHS program.
A WHS program is only as strong as the communications infrastructure that supports it. If lone worker monitoring, duress alarms, or emergency communications depend on mobile coverage your warehouse can't reliably provide, the control is not doing what it's meant to do.
MobileCorp specialises in in-building coverage for industrial and warehouse environments across Australia. Every project begins with an on-site RF assessment performed by a certified engineer, who measures real signal conditions, identifies dead zones, and designs a tailored solution around what they find.
