Once the plasterboard goes up, your cabling decisions are locked in for years. Forgotten data points, undersized conduit, a communications cabinet crammed into a cupboard as an afterthought: these aren’t things you fix later without cutting into a finished wall. Yet on plenty of new builds and renovations across Brisbane, the Gold Coast and the Sunshine Coast, data cabling gets about ten minutes of attention somewhere between the electrical plan and the final inspection, usually framed as “just run a few network points while you’re at it.”
That approach was fine when a house needed one point for a desktop computer and a phone jack in the hallway. It doesn’t hold up in a home running a mesh Wi-Fi system, three streaming boxes, a monitored alarm, four CCTV cameras, a NAS drive and someone working from home on a video call every day. Here’s what structured data cabling actually involves, what to get right before the walls close, and where it fits alongside the security systems most SEQ homes and businesses are installing at the same time.
Why This Is a One-Chance Decision
Electrical rewiring is disruptive but rarely catastrophic; you can chase a new circuit into an existing wall without too much drama. Data cabling is different in one important way: the cable needs a continuous, gentle-radius path from the data point back to a central cabinet, with no sharp bends, no running alongside power cables at close range, and no relying on a wireless workaround stapled on after the fact. Once walls are lined and insulated, retrofitting that path properly usually means either accepting a messier, lower-performance result (surface-mounted conduit, longer runs, compromises on cable separation) or opening up plasterboard you just paid to have finished.
That’s why the right time to plan data cabling is at the same stage you’re planning electrical, ideally before the frame is closed in on a new build, or before the walls go back up on a gut renovation. It costs very little extra to run cable while the walls are open. It costs a lot more, in both money and mess, to do it afterwards.
What “Structured Cabling” Actually Means
Structured cabling is the industry term for a planned, standardised network of cabling running from every data point in the property back to one central location, rather than a tangle of ad hoc extension cables and Wi-Fi extenders plugged in wherever a signal happens to be weak. Done properly, it follows the Australian/New Zealand standard for telecommunications cabling (AS/NZS 3080), which covers things like minimum bend radius, separation from power cabling, and labelling. Those details matter for performance and for anyone who has to service the system later.
Cat6/Cat6A vs Fibre: What’s the Difference
For most residential and small commercial jobs, Cat6 or Cat6A copper cabling remains the standard choice for individual data points. It’s cost-effective, handles gigabit speeds (Cat6A handles 10 gigabit over standard runs), and every piece of consumer networking gear plugs straight into it. Optic fibre earns its place in a few specific situations: runs longer than about 90 metres where copper’s distance limits start to bite, backbone connections between buildings or between floors in a multi-storey property, and sites that want serious future-proofing for very high speeds without a re-cable down the track. Most new builds don’t need fibre to every room, but a fibre backbone paired with Cat6A to individual points is a sensible middle ground for larger homes and commercial fitouts. Our optic fibre and data cabling team scopes this against the actual property rather than defaulting to one cable type across the board.
The Communications Cabinet: The Part Everyone Underestimates
Every data point needs to land somewhere, and that somewhere is the communications cabinet, sometimes called a comms cupboard or patch panel enclosure. This is where the NBN connection, the router, the patch panel, a network switch, and often the recorder for a CCTV system and the panel for an alarm system all come together. It needs power, ventilation (this equipment runs hot and hates being sealed in an airless cupboard), and enough physical space to actually work in when something needs fixing five years from now. A common mistake on new builds is a comms cabinet the size of a shoebox, tucked into the back of a linen cupboard with no power point: workable on the day it’s installed, a headache every day after.
What to Wire Before the Walls Close
On a new build or a full renovation, this is the practical checklist worth working through with your builder or electrician before first fix is signed off.
Data Points: More Than You Think You Need
A reasonable baseline for a family home is a data point in every bedroom, the living areas, a home office if there is one, and near each TV position where a smart TV or streaming device will sit. It’s tempting to cut this back to save a small amount on cable and labour, but the cost difference between wiring six points and wiring ten while the walls are open is minor compared to adding four more points after the fact. The same logic applies doubly to renovations, where reopening a finished wall to add “just one more point” is rarely a small job.
Wiring for Security at the Same Time
The new build or renovation stage is also the ideal time to plan cabling for CCTV cameras, an access control system on key entry points, and alarm sensors. Running these cable paths alongside the data cabling means a single, coordinated first-fix visit rather than three separate trades chasing cable through finished walls at different times. Homes and businesses that plan an integrated security system from the cabling stage generally end up with a cleaner install and fewer visible cables than ones that bolt security on after the building work is done. It also makes battery backup easier to plan, which matters in storm season; see what keeps working in a power outage.
Conduit: The Cheap Insurance Most People Skip
Running empty conduit alongside your data cabling, even just one or two extra runs to key locations, is inexpensive during construction and gives you a way to pull new cable through later without opening a wall, whether that’s for a future camera, a home theatre upgrade, or a technology that doesn’t exist yet. It’s one of the cheapest insurance policies available on a build, and one of the most commonly skipped.
Renovating Without Opening Every Wall
Not every renovation involves stripping a property back to the frame, and plenty of homes in the Sunshine Coast’s older housing stock and Brisbane’s established suburbs fall into this category: a kitchen and bathroom renovation, a partial extension, or simply a home that’s never had proper cabling installed. In these cases, cabling can often still be run through roof space, under-floor access and existing wall cavities without a full re-line, particularly in Queenslander-style homes with more accessible sub-floor space than a modern slab-on-ground build. It’s more labour-intensive than wiring an open frame, but it’s a very different job to opening finished plasterboard, and it’s worth getting an actual site assessment rather than assuming a retrofit isn’t possible.
Doesn’t Wi-Fi Make All This Unnecessary?
Wi-Fi has improved enormously, and a well-placed mesh system covers a typical home well for phones, tablets and casual browsing. But wireless still has real limits that cabling doesn’t: it’s shared bandwidth across every device competing for the same airtime, it can degrade through masonry walls and foil-backed insulation, and it’s a weaker foundation for anything that needs to be reliable and fast on demand, like a security camera recording continuously, a video call that can’t afford to drop out, or a smart TV streaming in 4K while someone else is on a work call down the hall. The best-performing home networks usually run a hardwired backbone with Wi-Fi layered on top for mobile devices. Cabling and Wi-Fi aren’t competing options; a good structured cabling job is what makes the Wi-Fi work well in the first place, because it lets you hardwire access points in the right locations instead of daisy-chaining range extenders.
Commercial Builds and Multi-Dwelling Sites
The stakes are higher on commercial fitouts, warehouses and multi-tenant or body corporate buildings, where a fibre backbone between floors or buildings, a properly sized comms room, and cabling planned to support monitored alarm and access control systems for many tenants is core infrastructure rather than optional extra scope. Retrofitting structured cabling into a completed commercial space, around finished ceilings and fire-rated walls, is a much bigger job than doing it during the base build or fitout stage. Our guides to construction site security and body corporate security on the Gold Coast cover the security side of those projects.
Frequently Asked Questions
How much does data cabling cost for a new build in Brisbane, the Gold Coast or Sunshine Coast?
It depends heavily on the number of data points, cable type (Cat6A vs fibre), and whether it’s bundled with a broader electrical or security fitout. Getting a quote against your actual floor plan is the only reliable way to price it; generic per-point figures online rarely account for run length, wall type, or comms cabinet requirements specific to your build.
Do I need an electrician or a data cabling specialist?
Both trades are often involved, but structured data cabling is its own specialty, with its own standard (AS/NZS 3080) and cabling registration requirements, covering things like cable separation, termination and network performance. Coordinating the two trades on the same first-fix visit is the efficient way to do it.
Is it worth running fibre in a residential new build?
For most homes, a Cat6A structured cabling setup is enough for the foreseeable future of normal use. Fibre earns its place for longer cable runs, backbone connections in larger or multi-storey homes, or where a homeowner specifically wants to future-proof for very high speeds. It’s a conversation worth having at the planning stage.
Can data cabling be added after a renovation is finished?
Yes, but it’s a bigger, messier job than doing it during construction. Expect surface-mounted conduit, longer or less direct cable runs, and generally a compromise on the clean result you’d get wiring an open wall. A site assessment will tell you what’s realistically achievable in a finished property.
Should I plan security system cabling at the same time as data cabling?
Yes. Running cable for CCTV, access control and alarm sensors during the same first-fix stage as your data cabling means one coordinated visit instead of separate trades chasing cable through finished walls later, and it sets up a properly integrated system from the start.
