Can Security Guards Detain You in Australia? | RC Security Group

Security guards play an important role in keeping people, businesses, and communities safe across Australia. From shopping centres and events to construction sites and corporate buildings, guards are often the first line of defence against theft, vandalism, and unsafe behaviour.

But many people wonder: can a security guard detain you in Australia? The short answer is yes, but only under specific circumstances defined by law. This guide explains when guards can detain someone, their legal powers, and your rights.

Can Security Guards Legally Detain You?

In Australia, security guards do not have the same powers as police officers. However, they do have the authority to perform a “citizen’s arrest” in certain situations.

According to Section 546 of the Queensland Criminal Code, anyone — including a security guard — can detain another person if:

They reasonably believe the person has committed an offence, such as theft, property damage, or assault.
The detention is necessary to stop the person from escaping until the police arrive.

This is commonly seen in situations like retail security, where guards may stop someone suspected of shoplifting until law enforcement takes over.

The Role of Security Guards in Australia

Before we dive into detention laws, it’s important to understand what security guards actually do. Their primary duties include:

Protecting people, property, and assets
Monitoring activity through CCTV monitoring systems
Controlling access to restricted areas with access control
Responding to alarms with professional alarm monitoring services
Assisting in emergency and incident response situations

Security guards are licensed professionals. In Queensland (including Brisbane), guards must hold a Security Provider Licence under the Security Providers Act 1993. This ensures they are trained, background-checked, and legally approved to perform their role.

When Can a Security Guard Detain You?

Here are common scenarios where a guard may legally detain someone:

Theft or Shoplifting – If caught stealing in a store or business, you may be detained by retail security guards.
Trespassing – Guards providing corporate security or protecting construction sites can hold someone unlawfully entering restricted property.
Violence or Threats – In event security, guards can detain people causing harm or posing a danger to others.
Damage to Property – If vandalism occurs, guards may stop and detain the suspect for the police.

However, the detention must always be reasonable and proportionate. Guards cannot use excessive force, hold someone for an unreasonable time, or carry out questioning like the police.

What Security Guards Cannot Do

It’s just as important to know what guards cannot do in Australia:

They cannot fine you.
They cannot search you without consent (unless it’s part of an entry condition, like at a concert or airport).
They cannot use unreasonable physical force.
They cannot detain someone simply for looking suspicious.

This is where strong communication skills and professional training come in. A skilled personal security guard will de-escalate situations calmly and involve police when necessary.

Rights of Individuals When Detained

If a security guard detains you, you still have rights:

You must be told why you are being detained.
You must be handed over to the police as soon as possible.
You have the right to remain silent until police arrive.
You cannot be forced to sign documents or make a statement.

Knowing your rights helps ensure that both individuals and guards act within the law.

The Importance of Professional Security Training

Detaining someone is a serious responsibility. That’s why professional security companies like RC Security Group focus on training guards in:

Conflict resolution
Emergency and incident response
Correct use of alarm monitoring systems
Handling access control points
Managing crowds in event security settings

With this training, guards are better equipped to keep people safe while respecting legal limits.

Supporting Guards with Modern Security Solutions

While guards can detain under the law, it’s often safer and more effective to use additional security measures. At RC Security Group, we combine manpower with technology for maximum protection.

CCTV Monitoring – Ensures incidents are recorded and can be used as evidence.
Mobile Patrol – Guards regularly check premises to deter criminal activity.
Alarm Monitoring – Immediate response to triggered alarms reduces risks.
Asset Protection – Prevents theft or damage to valuable property and equipment.

By combining human presence with advanced systems, we reduce the chances of guards needing to detain anyone at all.

Real-Life Example: Retail Theft

Let’s consider a real-world situation. A shoplifter is caught concealing items in a Brisbane store. The retail security guard observes through CCTV monitoring, approaches the individual calmly, and detains them under the citizen’s arrest rule. The police are called, and the suspect is handed over within minutes.

In this case:

The detention was legal.
The guard acted professionally and proportionately.
Evidence was supported by CCTV footage.

This demonstrates how a professional response protects both the business and the community.
