Mobile patrol security involves licensed security officers conducting scheduled or randomised patrols of your property in a marked vehicle. Unlike a static guard who remains on-site, a mobile patrol officer covers multiple client sites in a single shift, which is why the cost per patrol is substantially lower than a full-time static presence.

In Australia, mobile patrol services typically include:

• Scheduled perimeter checks — officers walk or drive the perimeter at agreed intervals
• Lock-and-unlock services — securing premises at close of business and opening at start of day
• Alarm response — responding to triggered alarms on behalf of the client, often included or billed per callout
• Incident reporting — GPS-stamped digital reports for each patrol, available via client portal
• Welfare checks — confirming lone workers or overnight staff are safe

Mobile patrol security is the most cost-effective way to maintain a visible security presence across a large site or multiple properties without the expense of permanent on-site guards.

1. Location and Travel Distance

The single biggest cost driver is how far your site is from the patrol officer’s base. Metropolitan Melbourne sites within an established patrol run are cheapest because one officer can efficiently cover 10–15 sites per shift. Regional cities like Geelong or Ballarat sit in the middle tier. Isolated rural properties where an officer must drive 30+ minutes for a single patrol will attract significantly higher rates.

2. Patrol Frequency and Duration

More patrols per night mean more officer time on your site. A single 15-minute nightly check costs far less than six randomised patrols across an eight-hour window. If your insurance policy or licence conditions require minimum patrol frequency, this will be reflected in the quote.

3. Site Risk Profile

High-risk sites — construction yards, chemical storage, active retail with high shrinkage rates, venues with recent incidents — require more thorough checks, more experienced officers, and sometimes additional equipment. Providers will price this risk accordingly.

4. Alarm Monitoring Integration

If your patrol provider also monitors your alarm system, the response time is faster and the bundled cost is lower than paying two separate providers. Ask specifically whether alarm response is included or billed as a callout.

5. Contract Length

Longer-term contracts (12 months+) typically unlock lower monthly rates because the provider can plan their patrol runs efficiently. Month-to-month arrangements cost more per patrol but offer flexibility.

When requesting quotes from multiple providers, ensure you compare like for like. The following checklist helps you evaluate each proposal:

When evaluating security options, many businesses compare mobile patrol against static guard services. The two serve different purposes, and the cost difference is significant:

For many sites, a hybrid approach works best — mobile patrols overnight plus static coverage during operating hours. This significantly reduces the cost of 24/7 coverage compared to a static-only solution.

What Is Included in a Mobile Patrol Contract?

Before signing any mobile patrol contract, confirm exactly what is and is not included. A well-structured agreement should include:

• Patrol frequency and timing — specified as a minimum number of patrols per shift, with randomised arrival times
• Checkpoint verification — GPS-logged proof that the officer physically attended each checkpoint
• Alarm response protocol — whether alarm activations are included or billed as callouts, and what the guaranteed response time is
• Incident reporting — how incidents are documented and when you are notified
• Escalation procedures — what happens when the officer encounters a break-in, trespasser, or medical emergency
• Key-holding arrangements — whether the provider holds a key or access code for your property
