Introduction

Most people have seen a security guard at a building entrance, shopping centre or event, but what are they actually responsible for during a shift? What does a security guard do beyond watching who comes and goes?

For a business owner or property manager, knowing the answer matters. A guard may monitor your premises, check access points, carry out patrols, identify suspicious activity, record incidents and respond when a security issue occurs. Their daily duties can also change depending on whether they are protecting an office, warehouse, construction site, retail store or event.

In Melbourne, private security is a licensed industry, with training requirements applying to most security activities. So, let’s break down the security guard duties and roles of a security guard, what you can expect during a typical shift, and how their work helps protect your people, property and assets.

What Does a Security Guard Do?

A security guard helps protect people, property and assets by watching assigned areas, controlling access, carrying out patrols and responding to security concerns within their role and training.

The Fair Work Ombudsman’s Security Services Industry Award lists duties such as watching, guarding and protecting people or property, controlling movement at entrances and exits, responding to basic alarms and carrying out crowd control.

Here’s the thing: the roles of a security guard are not identical at every site. An office may need visitor management, while a construction site may need regular perimeter checks.

Main Security Guard Duties

1. Monitoring and surveillance

Guards remain vigilant to activities within their designated area. Based on the location, it could include:

• Monitoring exits, entrances and restricted zones
• Monitoring suspicious activity
• The use of CCTV or any other security equipment if needed
• Verifying for signs of damage or access that is not authorised

Alfa Security provides on-site guards with surveillance technology. The company provides surveillance, situational awareness of the situation, and emergencies as a part of their offerings.

2. Patrolling the premises

Patrols help guards check areas that may not be visible from a fixed position. A patrol may cover:

• Perimeters and fencing
• Doors and gates
• Car parks
• Storage or loading areas
• Other agreed security checkpoints

3. Controlling access

At an office, warehouse or on a construction site, security personnel can monitor visitors who come in and exit. This may include checking authorised access, directing visitors and observing site rules.

The Fair Work Award specifically recognises the management of the movement of persons as well as vehicles, items and other property at entry points and exits as a security guard job.

4. Recording and reporting

Good security work also involves accurate records. Guards may document incidents, observations, alarms or other matters and pass important information to the relevant person or team.

How the Role Changes by Workplace

WorkplaceCommon priorities

Office Visitor management, access control, reception security and internal patrols

Retail Visible presence, customer safety and monitoring suspicious behaviour

Warehouse Perimeter checks, access control and asset protection

Construction site Entry points, patrols, equipment protection and unauthorised access

Event Entry management, crowd control and incident response

For example, Alfa Security’s corporate service includes access control, reception security and internal patrols, while its construction service focuses on monitoring entry points and regular patrols.

What Happens During a Typical Shift?

The shift of a security guard typically begins with knowing the website’s guidelines and any other issues that require attention.

While on shift, the guard could:

1. Check assigned areas and access points.
2. Monitor people, vehicles and activity.
3. Conduct required patrols.
4. Respond to security concerns.
5. Record relevant incidents or observations.
6. Pass important information to the next shift or responsible person.

This is why security is not simply about being physically present. Consistent observation and following clear procedures are central to the role.

What Does a Guard Do During an Incident?

When something unusual happens, the guard follows the site’s procedures and acts within their training and authority.

This may involve:

• Assessing what is happening
• Communicating with relevant people
• Managing the situation safely
• Escalating the matter when required
• Contacting emergency services where appropriate
• Recording what happened

First response to security incidents is a duty of higher-level security officers according to the Fair Work Award.

It’s also important to remember that private security guards are not police officers. Their powers and responsibilities depend on their licence, training and the circumstances.

In Victoria, most private security activities require approved training relevant to the activity, and security work is subject to licensing requirements.

Do You Need a Security Guard?

Start with your actual risk rather than choosing a service first.

Ask yourself:

• What are we protecting: people, stock, equipment or property?
• Which areas have the highest risk?
• Are problems more likely during business hours or overnight?
• Do we need someone permanently on-site?
• Would regular mobile patrols be enough?
• Do we need access control or incident response?

For a Melbourne business, the answer could be static guarding, mobile patrols, CCTV monitoring, gatehouse security or a combination of services. Alfa Security provides these types of security options across Melbourne.

Good Security Starts With Knowing the Job

A security guard does much more than stand at a door. Their work can involve surveillance, patrols, access control, reporting, communication and incident response, with the exact duties shaped by the site.

For your business, the right question is not simply, Do we need a security guard? It is: What risks do we need someone to manage, and what level of on-site support makes sense?

If you are unsure, speak with a professional security provider about your property, operating hours and specific concerns before deciding on the right coverage.
