Marlin Coast Alarms
A 20-year commercial client relationship sets this small Cairns security team apart from the crowd.
The standout detail is a 20-plus-year commercial relationship with a Cairns business, which is rare for a sole trader and suggests genuine reliability over the long run, not just a good first impression. When calling, it's worth confirming current availability, which suburbs they cover, and whether they carry the specific camera or alarm brands you're looking at.

About Marlin Coast Alarms
Josh and Greg are the named technicians behind this Bungalow-based security outfit, with Josh and Greg between them handling both residential camera-and-alarm packages and longer-term commercial accounts. The commercial side is notable: Cairns Signcorp, a local signage business, has been a client for over two decades — which is unusual for a sole trader operation and points to a capacity for ongoing service relationships rather than just one-off installs. On the residential side, the work reviewed involved setting up security cameras and alarms for a family home, suggesting the team is comfortable working directly with homeowners who want practical peace-of-mind solutions rather than enterprise-scale systems. With roughly 11 years of operation in the Cairns region, Marlin Coast Alarms sits in a niche that bridges domestic and small-business security — useful if you're a homeowner who also runs a local business and wants one provider for both. The team is described as courteous and timely, with reviewers specifically noting follow-up after the initial install rather than a drop-and-go approach.
Best for: residential camera and alarm installs for family homes, small-to-medium businesses wanting a reliable long-term security provider, and homeowners who want post-install follow-up rather than a one-time setup.

Who actually does the work at Marlin Coast Alarms?+
Reviews name Josh and Greg as the technicians on the tools. One review specifically credits them with setting up cameras and alarms for a residential property, while a separate commercial client describes a team that is courteous and proficient in their trade. Given the sole trader structure, it's worth confirming directly who will attend your job and whether both are available for your timeframe.
Do they take on both home and business security jobs?+
Yes — the two available reviews cover both sides. One involves a residential camera and alarm setup for a family home, and the other comes from Cairns Signcorp, a commercial signage business that has used Marlin Coast Alarms for over 20 years. If you run a small business and also need home security sorted, this could be a practical single-provider option worth exploring.
What areas around Cairns do they service?+
The business is based in Bungalow, QLD, which is a suburb of Cairns, and at least one reviewed commercial client is also in Cairns. Beyond that, the reviews don't specify exactly how far they travel for jobs. Call ahead to confirm whether they cover your suburb, particularly if you're outside central Cairns.
Do they provide any follow-up support after installation?+
One reviewer specifically praises the 'professional service and follow up for any security requirements,' and the 20-plus-year retention of a commercial client suggests this isn't just talk. That said, only 2 reviews mention this, so it's worth asking directly what post-install support looks like — for example, whether they offer service calls if something stops working or needs adjusting after the initial fit-out.
How much experience does Marlin Coast Alarms have?+
The business has been operating for approximately 11 years, and one commercial reviewer mentions a 20-plus-year client relationship — which predates the business's current listing and suggests a long personal track record in the industry. Reviews don't mention specific certifications or licence numbers, so if that's important for your job (particularly commercial compliance work), confirm their credentials when you call.
