What is a lone security worker and why do they need welfare checks?
A lone security worker is a guard performing their duty without another person in the immediate vicinity to assist in an emergency. The category includes mobile patrol officers completing a solo beat across multiple sites, static guards posted overnight at unstaffed facilities, and in some configurations, guards at remote or industrial sites without reliable telecommunications.
The risk is straightforward: if something goes wrong, whether a medical event, an assault, an accident, or a duress situation, there is no one nearby to raise the alarm or render assistance. Without a welfare check process, a guard can be incapacitated for a significant period before anyone knows. In serious cases, delayed discovery changes the outcome.
Security work is consistently identified in WHS statistics as a higher-risk occupation for workplace violence. A welfare check process is the operational response to that risk when a guard is working alone.
The WHS duty-of-care framework for lone workers
Under the Work Health and Safety Act 2011 (Cth) and the equivalent WHS legislation in each state and territory, a person conducting a business or undertaking (PCBU) has a primary duty to ensure, so far as is reasonably practicable, the health and safety of workers. This duty applies to the manner in which work is carried out, the working environment, and any risks associated with the particular work.
Safe Work Australia and state WHS regulators have published specific guidance on managing the risks of isolated and lone workers. The duty is not to prevent all harm, which is impossible, but to manage risk so far as is reasonably practicable. For lone security workers, a welfare check process is a direct and well-established control measure.
Western Australia, Queensland, and some other states have additional guidance or codes of practice specifically addressing isolated and remote work. Employers should check the guidance published by the WHS regulator in each state where they operate. Key regulators include:
- Safe Work Australia (national guidance and model codes)
- SafeWork NSW
- WorkSafe Victoria
- Workplace Health and Safety Queensland
- SafeWork SA
- WorkSafe WA
Welfare check intervals: how to determine the right frequency
There is no legally prescribed check interval that applies across all lone security work in Australia. The appropriate interval is a risk-based judgement, and a written risk assessment is both the correct starting point and the documented evidence that you applied your duty of care.
Factors that typically drive a shorter check interval:
- High-risk site (history of incidents, poor telecommunications, remote location)
- Duty involving higher risk activity (cash handling, venue after-hours access, site with known security threats)
- No duress device or no reliable mobile coverage
- Guard working alone for an extended overnight window
Factors that may support a longer check interval:
- Guard has a reliable duress device that auto-escalates to a monitoring centre
- Lower-risk site with CCTV coverage and a monitoring centre watching the feed
- Multiple guards in the same building, even if not on the same floor
As a general practice in the Australian security industry, welfare checks for lone guards at higher-risk sites are often set at 30-minute to 1-hour intervals. Patrol circuits with GPS tracking are sometimes treated as continuous check-in by some companies, on the basis that a route deviation is detectable. This is not a legal determination; document your reasoning in the risk assessment.
Designing an effective escalation process
A welfare check process is only as good as its escalation path. When a guard does not respond, a clear documented sequence must take over immediately. An escalation that relies on a supervisor's memory of who to call next is not adequate.
An effective escalation design has the following properties:
These levels are a framework, not a prescribed legal requirement. The appropriate escalation steps and timing depend on your risk assessment, the nature of the site, and the communication tools available. Document your escalation procedure in writing and train all supervisors on it.
Evidence and records: what to retain and why
If an incident happens to a lone security worker, the employer's welfare check records become material evidence in:
- WHS investigations by the relevant state regulator
- Coronial inquiries
- Insurance claims (both the employer's liability insurer and workers' compensation)
- Civil claims by the worker or their family
At a minimum, welfare check records should capture: the date and time the check was initiated, how the check was conducted, who initiated it, what response was received (or that no response was received), and any escalation actions taken with timestamps. Retain these records for the period required by applicable law (check your state WHS regulator and workers' compensation legislation for minimum retention periods; many require records to be kept for several years after employment ends).
A system that automatically timestamps welfare check events and escalation actions produces records that are difficult to dispute and easy to export for an investigation. Handwritten logs are legally valid but are more susceptible to being lost, illegible, or incomplete.
Welfare obligations for subcontractors and labour hire
Under the WHS model law, a PCBU's duty extends to workers who are not direct employees. A subcontractor or labour hire worker assigned to your client site, working under your direction, is generally treated as a worker for WHS purposes. Your welfare check obligations apply to them in the same way as to your direct employees at that site.
Before deploying a subcontractor to a lone-worker role, confirm that your welfare check process will cover them: that you have their contact details, that they know how the check-in works, and that they understand the escalation procedure if they do not respond.
Rostering subcontractors is covered in the security guard rostering guide.

Frequently asked questions
What is a lone worker in the security industry?
A lone security worker is a guard who performs their duty without another person nearby to assist in an emergency. This includes mobile patrol officers working a solo beat, static guards at an unstaffed site overnight, and monitoring centre operators in some configurations. The key characteristic is that if something goes wrong, there is no one immediately present to help or raise the alarm.
Is there a legally required welfare check interval for security guards in Australia?
There is no single prescribed interval mandated across all jurisdictions in Australia. The Work Health and Safety Act 2011 (Cth) and equivalent state and territory legislation require employers to manage risks to health and safety, including for isolated workers. What constitutes appropriate welfare check frequency is a risk-based determination. Employers should document their risk assessment and derive the interval from that assessment, rather than applying an arbitrary figure. Guidance documents from Safe Work Australia discuss managing the risks of isolated work.
What should happen when a security guard misses a welfare check?
A missed welfare check should trigger an escalation process. The first step is typically a call-back attempt directly to the guard. If unanswered after a defined time, escalation moves to the supervisor, then to the site contact or another guard in the area, and if there is still no response, to emergency services. The exact escalation path and timing should be documented in a written welfare check procedure before a situation arises, not improvised during one.
Do welfare check obligations extend to subcontractors working at my direction?
In most cases, yes. Under the WHS model law, a person conducting a business or undertaking (PCBU) has duties to workers, including workers who are not direct employees but who are carrying out work for the business. A subcontractor assigned to your site under your direction will generally be covered by your welfare obligations. If you deploy a subcontractor to a site where you have a welfare check requirement, confirm that your welfare check process covers them.
What records should I keep for lone-worker welfare checks?
At minimum: the time the check was initiated, the method used, the response received (or not received), and any escalation steps taken. If an incident occurs, these records demonstrate that the employer met their duty of care. They are also relevant in coronial inquiries, insurance claims, and WHS investigations. A digital system with timestamped, auditable records is preferable to paper logs that can be lost or are difficult to search.
