So you need to get some cabling work done at your Perth business, and now you’re hearing terms like “open cabling license” thrown around. It can feel overwhelming, especially if you have no idea what any of it means or why it even matters.
Here’s the thing: hiring the wrong cabling contractor can land your business in serious trouble. We’re talking failed inspections, voided warranties, and even safety hazards that could put your staff and customers at risk. That’s why understanding what an open cabling licence actually is before you sign anything is so important.
The good news? You don’t need to be a tech expert to get your head around this. In this post, we’re breaking it all down into simple, easy-to-follow points so you can hire with confidence. By the time you finish reading, you’ll know exactly what an open cabling licence covers, why it matters for your business, what questions to ask a contractor before hiring them, and how to avoid some of the most common (and costly) mistakes Perth business owners make. Let’s get into it.
What Is an Open Cabling Registration?
You might have heard the term “open cabling licence” thrown around, but the correct Australian term is actually ACMA Open Cabling Registration, sometimes called an open cabler licence. It is governed by the Telecommunications (Cabling Provider) Rules, which sit under the Telecommunications Act 1997. The rules were also refreshed in April 2025, so any older references to the “2014 Rules” you find online may be a little out of date.
The body behind all of this is the Australian Communications and Media Authority (ACMA), a federal regulator that decides who is legally allowed to install telecommunications cabling anywhere in Australia. Think of ACMA as the rule-maker, setting the standards and training requirements that every cabler must meet before they can legally pick up a cable and get to work.
The Australian Cabler Registration Service (ACRS) is the organisation that actually processes registrations and keeps a searchable public record of every registered cabler in the country. This is important for you as a homeowner or business owner, because you can look up any contractor before they start work on your property.
Without this registration, a person is simply not allowed to carry out open cabling work, full stop. There are no state-based exceptions; it is a national requirement. For you, that means hiring an unregistered cabler could create real problems, including insurance headaches, network safety risks, and potential legal liability if something goes wrong down the track.
The Three Cabling Registration Categories
Not all cabling registrations are created equal. There are actually three distinct categories, and each one comes with a different scope of work that a contractor is legally allowed to perform. Here is a quick breakdown so you can see exactly how they compare.
| Registration Type | Where They Can Work | What It Covers |
|---|---|---|
| Open | Homes, offices, commercial buildings, multi-tenancy | Structured, coaxial, optical fibre, aerial, underground |
| Restricted | Residential and small offices only | Limited to restricted cabling work |
| Lift | Lift shafts and elevator systems only | Communications cables within lifts |
Open Registration is the broadest of the three. A contractor with this registration can work across all property types, from a family home right through to a large commercial office or multi-tenancy building. It covers structured cabling, coaxial, optical fibre, aerial, and underground cabling. You can read the full official breakdown on the ACMA categories of cabling registration page.
Restricted Registration is more limited. It only covers residential properties and small offices that fall under single-phase power up to 230V AC or three-phase up to 400V AC. A contractor holding only this registration cannot legally take on larger commercial jobs.
Lift Registration is highly specialised. It only covers cabling work inside lift shafts and elevator systems, so it has no overlap with standard commercial or residential cabling.
Here is the key takeaway for business owners: if you run a commercial office, a multi-tenancy building, or anything beyond a small home-based setup, you need a contractor with Open Registration. A Restricted Registration simply does not cover that kind of work, no matter how experienced the contractor seems.
What an Open-Registered Cabler Is Allowed to Do
So now that you know what Open Registration is and how it compares to other categories, let’s look at what an open-registered cabler can actually get their hands on day to day.
Structured cabling is one of the most common tasks. This includes installing and terminating Cat 5, Cat 6, and Cat 7 cables for data, internet, and phone networks in homes and businesses alike. Whether it’s wiring up a small home office or running cables through a multi-floor commercial building, open-registered cablers are qualified for both. All work needs to meet the AS/CA S009 cabling standard, and a Structured Cabling Endorsement is specifically required for terminating Cat 6 cable.
Coaxial cabling is also part of the picture. This covers TV, satellite, and antenna systems, as well as CCTV security camera wiring where it connects to a telecommunications network. It’s a handy skill set for anyone working across residential properties or commercial sites with security systems.
Optical fibre is another big one. Open-registered cablers can run fibre cabling for high-speed internet, including Fibre-to-the-Premises (FTTP) work tied to the NBN rollout. Given how quickly the NBN continues to expand across Australia, this is a very in-demand skill right now.
Aerial and underground cabling rounds things out nicely. These installations come into play on larger properties or sites where cables need to travel between separate structures.
On top of all this, open-registered cablers can add specialist endorsements to their registration, including Structured Cabling, Optical Fibre, Coaxial, Metallic Testing, Fibre Testing, Underground, and Aerial. Each one requires additional dedicated training through a registered training provider, but they significantly expand the type of work you’re qualified to take on.
Why Hiring a Registered Cabler Protects You
Hiring an unregistered cabler might seem like a way to save a bit of money upfront, but it can end up costing you significantly more down the track. Here are five solid reasons why using a registered cabler is always the smarter choice.
1. It could void your insurance
If a fault or fire is ever traced back to improperly installed telecommunications cabling, your insurer may refuse your claim entirely. Building and contents insurance policies generally require that all work carried out on your property meets Australian compliance standards. Unlicensed cabling work does not meet those standards, which gives insurers grounds to deny a payout. That is a risk that simply is not worth taking.
2. You could be held legally liable
Under Australian telecommunications law, specifically the Telecommunications Cabling Provider Rules 2014, all cabling that connects to the telecommunications network must be done by a registered cabler or someone under their direct supervision. If unlicensed work is discovered on your property, the legal responsibility can fall on you as the property owner, not on the person who did the work. Ignorance of who you hired is not a valid defence.
3. You pay for the fix, not the contractor
If non-compliant cabling is identified during an inspection or after a fault, the cost of rectification is your problem. The unlicensed contractor has no formal accountability, leaving you to organise and fund the repair work yourself.
4. There is a formal complaints process
Registered cablers are accountable to ACMA and registrars like ACRS. If something goes wrong, you have a real pathway to make a complaint and seek resolution. With an unregistered person, you have no such recourse.
5. Poor cabling hurts your business operations
For businesses, non-compliant cabling often leads to ongoing network reliability issues, dropped connections, slow speeds, and unpredictable outages. The consequences are not just legal; they affect productivity and day-to-day operations directly.
How to Check Your Contractor’s Registration Before You Hire
Before any work starts, it is worth taking five minutes to check that the person you are hiring is actually registered. It is free, easy, and could save you a lot of headaches later. Here is exactly how to do it.
Step 1: Visit the official cabler search tool
Head to the ACMA find a registered cabler page to locate the public database of registered cablers in Australia. This is the go-to resource for confirming whether someone is legitimately registered before they set foot in your home or business.
Step 2: Search by name or licence number and check the category
Type in the contractor’s name or their registration number and look at what category comes up. You want to see “Open” listed as their registration type. If it shows “Restricted,” that contractor has a limited scope of work they can legally carry out, which may not cover what your job actually involves. Always confirm this before signing anything.
Step 3: Make sure the registration has not lapsed
Registrations are not permanent. They have an expiry date and must be renewed regularly. A lapsed registration means the contractor is not currently authorised to perform cabling work, even if they were qualified in the past. The search result will show whether the registration is currently active, so check this carefully.
Step 4: Confirm the right endorsements for your job
If your project involves optical fibre, structured cabling, or coaxial work, check that the contractor holds the matching endorsement on top of their Open Registration. Not every open-registered cabler holds every endorsement, so it is worth confirming this upfront.
One last thing worth remembering: a professional, experienced cabling contractor will never hesitate when you ask for their registration details. If someone gets uncomfortable with the question, that is a red flag. Any reputable tradesperson understands that verification is simply part of doing business properly.
Real-World Cabling Jobs That Require Open Registration in Perth
Still not sure what jobs actually need an open cabling registration? Here are five real examples you will come across regularly in Perth.
1. Cat 6 structured cabling for a commercial office network
This is one of the most common jobs in Perth right now. When a business wants to set up a proper wired network, a registered cabler needs to run Cat 6 cables through the building, terminate them at patch panels and wall plates, and connect everything to a UniFi switch and access points. Every single cable termination point counts as cabling work under ACMA rules, so only someone with Open Registration (plus a Structured Cabling Endorsement) can legally do this.
2. CCTV cabling in a retail shop or warehouse
Running coaxial or Cat 6 cable through ceiling cavities to connect cameras to an NVR recorder is a job that requires proper registration. The cable is being routed and terminated as part of a permanent installation, which puts it squarely under the ICTSS00084 Open Cabler Registration Skill Set framework. For coaxial cable runs specifically, a Coaxial Cabling Endorsement is also needed on top of the base Open Registration.
3. Starlink ground cabling through walls or under a building
If a Starlink dish cable is just draped along the outside of a wall, no registration is needed. But the moment that cable goes through a wall, under a floor, or into a ceiling cavity as a clean permanent installation, it becomes customer premises cabling work under ACMA rules. This is a grey area that catches a lot of installers out, and plenty of Starlink installs in Perth are done without the right credentials.
4. Fibre or FTP cabling in a server room or data cabinet
Connecting floors or separate buildings across a business campus using fibre cabling requires an Optical Fibre Cabling Endorsement on top of the Open Registration. If the job involves FTP copper structured cabling inside a server room rather than fibre, that falls under the Structured Cabling Endorsement instead. The two are different cable types with different endorsement requirements, which is worth knowing before you hire anyone for this kind of work.
5. Hardwired data points for a home office
A lot of Perth homeowners working from home want a proper wired connection instead of relying on Wi-Fi. Installing Cat 6 data points and wall plates in a residential property is still classified as cabling work, meaning a registered cabler must do it. A homeowner cannot legally self-install internal telecommunications cabling. The Basic Open Cabler Registration Skill Set listed through Jobs and Skills WA confirms this is a formal, qualified trade, not a DIY task.
