Oz Tech Security
Two decades in Mandurah with commercial clients staying for seven years or more — longevity that speaks for itself.
That said, all 4 are from what read like genuine long-term commercial clients rather than one-off jobs, and two explicitly mention multi-year relationships, which is a more meaningful signal than a stack of post-installation reviews from strangers. The 20-plus years in operation combined with repeat commercial client loyalty suggests a business that lives on referrals and retention rather than volume — worth asking them directly whether they take on residential security installations or focus primarily on commercial premises.

About Oz Tech Security
Running a security business in Mandurah for over two decades puts Oz Tech Security in a different category from newer entrants — they've seen enough alarm systems, camera setups, and commercial fit-outs to know what actually works in this region. Reviews point clearly to commercial clients as their bread and butter: a hair salon that's used them for over seven years and a business that brought them in during a full renovation both speak to an ability to work around operating premises without disrupting day-to-day life. Their renovation project work stands out specifically — fitting an alarm system on schedule and to budget during a commercial refurbishment is the kind of outcome that's hard to find. What customers describe as 'approachable and knowledgeable' suggests they take time to understand a client's specific security requirements rather than pushing a standard package, and the repeated mentions of long-standing relationships indicate they stay engaged after installation. Structured as a trust entity and GST-registered, they operate with the administrative setup of a professional services firm rather than a sole trader. For homeowners, particularly those who want a security provider with proven longevity and a track record in commercial spaces, they're worth a direct conversation.
Best for: commercial premises requiring security installation during renovations, businesses wanting a long-term service relationship rather than a one-off install, and clients in the Mandurah region looking for an operator with multi-decade local experience.

Does Oz Tech Security work on residential properties or mainly commercial jobs?+
Based on the available reviews, their visible client base skews commercial — a hair salon, a business undergoing renovations, and references to 'premises' rather than homes. However, this likely reflects who leaves public reviews rather than the full scope of their work. With over 20 years operating in Mandurah, it's worth calling them directly to ask whether they handle residential alarm and CCTV installs, as many regional security businesses do both.
What do customers say about Oz Tech's pricing?+
One reviewer specifically called out 'a great price' alongside quality work, and another noted the renovation project was completed 'to budget,' which suggests they hold firm on quotes rather than adding surprises. Reviews don't give enough detail to benchmark their rates against competitors, so it's worth getting a written quote and comparing. Given the small review sample, this pricing feedback comes from a limited data set.
How long has Oz Tech Security been operating in Mandurah?+
They've been active for over 20 years, which is a meaningful marker in a trade where many smaller operators come and go. Two of their four Google reviewers describe themselves as long-standing customers — one relationship spans over seven years — which is consistent with a business that retains clients through ongoing service rather than just installation work.
Does Oz Tech Security provide ongoing maintenance and service after installation?+
Yes, this appears to be a genuine part of what they offer. One reviewer praised their 'ongoing commitment to service delivery' following an alarm installation during a renovation, and another described being a customer for over seven years — implying a continuing service relationship rather than a one-off install. If you want a provider who stays engaged after the job is done, this seems to be a practical fit, though confirming the specifics of their service agreements directly would be worthwhile.
Are there any concerns to be aware of before hiring Oz Tech Security?+
The main thing to flag is the limited public review record — all 4 Google reviews were posted in a short window in 2019, so there's no recent feedback to draw on. This doesn't mean anything negative happened since then, but it does mean you can't rely on recent customer experiences as a guide. Asking them for current client references, particularly from commercial premises similar to your property, would be a sensible step before committing.
