How to Choose the Right Tracking System for Vehicles and Trailers in Australia

A tracking system for vehicles is a smart way to keep trailers secure and easy to manage. In Australia, trailers are often targeted by thieves because they can be moved quickly and usually don’t have built-in security. A GPS tracking device offers real-time location updates, movement alerts, and geo-fencing to help prevent theft and improve recovery.

These systems are especially helpful for tradespeople, delivery services, and businesses that rely on trailers to carry tools, equipment, or goods. With the right tracker, trailer owners can monitor location, deter unauthorised use, and respond quickly if something goes wrong. GPS tracking also supports better route planning, usage tracking, and operational efficiency. 

In this article, we’ll look at how these systems work, what’s legal in Australia, and how to choose the best device for your trailer.

What Is a Vehicle and Trailer Tracking System?

A tracking system for vehicles is a technology-driven tool that helps monitor the real-time location and movement of trailers or vehicles. Most systems rely on GPS technology, which connects with satellites to determine the exact position of the tracker. This data is then sent to a mobile app or online platform, where users can check movements, set alerts, and review past locations.

In the trailer industry, GPS tracking is especially valuable. Trailers are often left unattended at worksites, in driveways, or on job sites—making them easy targets for theft. A discreetly placed tracker can alert owners or managers if a trailer is moved unexpectedly, helping them act quickly.

These systems are often called automobile tracking devices or vehicle GPS tracking devices, and they can be used permanently or temporarily. Many also include useful features like geo-fencing, speed alerts, and route tracking, which are ideal for businesses operating across multiple locations in Australia.

Are Tracking Devices Legal in Australia?

Tracking devices are legal in Australia, but their use is regulated by surveillance and privacy laws that differ across states and territories. The main consideration is who owns or controls the asset. If you own the trailer or vehicle or operate a business using trailers, you’re generally permitted to install a GPS tracker—provided it’s used lawfully and transparently.

Permitted Uses of Tracking Devices

You can legally install a tracking system for vehicles or trailers in the following circumstances:

• The trailer is your property, and you’re installing the tracker for security or asset management.
• You operate a business and have notified employees that GPS tracking is in place.
• The data is used to support legitimate operational functions, such as fleet coordination or theft prevention.

Restrictions and Compliance

Using tracking devices covertly—especially on assets you don’t own—can breach laws like the Surveillance Devices Act in your state. Key points to observe include:

• Consent is typically required if the trailer or vehicle is used by others.
• Tracking without notice may violate a person’s expectation of privacy.
• Businesses must ensure they comply with the Privacy Act 1988 (Cth) when collecting and storing tracking data.

States like New South Wales and Victoria have specific legislation outlining how and when tracking devices can be used. For trailers operated across multiple job sites or shared among staff, clear written policies and user consent are strongly recommended to remain compliant.

AirTag vs GPS: Which Works Better for Trailers?

With several tracking options on the market, trailer owners often ask: is an Apple AirTag enough, or is a dedicated GPS tracker more suitable?

Key Differences Between Air Tags and GPS Trackers

Why GPS Trackers Are More Effective for Trailers

AirTags are designed for short-range personal use—such as keys or bags—not for real-time asset tracking. They rely on Apple’s “Find My” network, meaning location updates are only triggered when an iPhone is nearby. This makes them unreliable for long-distance trailer tracking, especially in rural or industrial areas where trailers are often used or stored.

In contrast, GPS trackers:

• Provide real-time location data via satellite and cellular networks
• Allows geo-fencing, movement alerts, and detailed tracking history
• Are more secure and harder to detect or disable
• Work effectively in remote regions where trailers are vulnerable to theft

Best Choice for Trailers

For monitoring trailers used in business or trade, a vehicle tracker GPS offers significantly more reliability and coverage. It’s a purpose-built solution designed to help owners respond quickly to unauthorised movement or theft—capabilities AirTags simply cannot deliver.

What Can a Vehicle or Trailer Tracking System Be Used For?

A tracking system for vehicles has a wide range of applications, particularly for trailers used in commercial, industrial, and recreational contexts. These systems are not limited to theft prevention—they also support operations, improve safety, and enhance overall efficiency.

1. Business Use

For businesses that rely on trailers—such as construction, landscaping, transport, or mobile services—GPS tracking offers several benefits:

• Fleet management: Monitor the location and status of multiple trailers across worksites or delivery routes.
• Theft deterrence: Discreetly installed trackers can help recover stolen trailers quickly, reducing downtime and loss.
• Job site accountability: Track when and where trailers are moved, helping verify timelines and reduce misuse.
• Route optimisation: Analyse routes to reduce fuel use, save time, and improve scheduling.

Companies using enclosed trailers to transport tools or custom-fit setups for mobile operations gain added value from tracking through improved oversight and asset protection.

2. Family and Recreational Use

For individuals and families who use trailers for leisure or personal projects, tracking systems provide peace of mind:

• Theft recovery: Trailers used for camping or off-roading are often stored outdoors or left unattended—GPS tracking improves recovery chances if stolen.
• Location sharing: When travelling across remote areas, real-time tracking allows family members to know your location.
• Emergency support: In case of breakdowns or disconnection during transit, knowing your trailer’s location simplifies assistance.

Tracking solutions also help safeguard trailers used to tow boats, caravans, or motorbikes—especially valuable in regions where trailer theft is common.

Choosing the Right Vehicle GPS Tracking Devices

Selecting the right tracking system for vehicles depends on how your trailer is used, how often it moves, and the level of security or reporting you require. The two main types of GPS tracking setups for trailers are fixed and portable. Each option offers distinct advantages depending on your operational needs.

Fixed GPS Setup

A fixed GPS tracker is hardwired into the trailer’s electrical system or installed with a long-life battery. This type of setup is ideal for commercial trailers or high-value units that require permanent tracking.

Key benefits include:

• Reliable power supply from the vehicle or rechargeable battery
• Tamper-resistant installation, making it harder to remove
• Consistent tracking, even during long-distance transport
• Ideal for fleet operators, utility trailers, or enclosed trade trailers

Fixed trackers are particularly effective for businesses using multiple trailers across job sites, where ongoing visibility and security are critical.

Portable GPS Setup

A portable GPS tracker is a compact, self-powered device that can be placed inside or attached underneath the trailer. These devices are better suited for short-term use, private owners, or those wanting more flexibility.

Key advantages:

• No wiring required, allowing for quick setup
• Easily transferable between different trailers or vehicles
• Discreet installation, such as in toolboxes or compartments
• Ideal for casual trailer users, campers, or occasional towing

Some small GPS trackers come with magnetic mounts or waterproof casing, making them well-suited for outdoor and off-road conditions.
