Why Does NBN Do a Full Install for Some Homes and Not Others?
Oct 19, 2026
If you've watched a neighbour get their full fibre upgrade done properly — NTD installed in a sensible spot, no fuss, no extra cost — while you've been told to organise and pay for a cable pathway, you're right to be annoyed. Same street. Same house type. Completely different outcome.
We see this constantly across Perth. It's one of the most common things customers ask us about, and the honest answer is: the work NBN does on the day depends heavily on which technician you get.

What NBN is supposed to offer you
NBN's installation guidelines state that the indoor connection box (the NTD) should be installed within a 12 metre radial distance of the outdoor utility box. Within that radius, and subject to power access and a suitable location, NBN should complete the installation at no cost as a standard install.
That's the baseline. The technician's job is to find a compliant location within that scope. If they can't meet every guideline on the day, NBN's own documentation says "exceptions may be considered."
More importantly, NBN's customer pathway fact sheet is explicit: the technician "will offer at least one installation option consistent with nbn's fibre installation guidelines that doesn't require the customer to arrange a Customer Installed Fibre Cable Pathway."
Read that again. The default position is supposed to be a free option. A customer-installed pathway is what you choose if you're unhappy with the free option and want something different — not what you're told to arrange because the technician couldn't be bothered finding a compliant spot.
The inconsistency is the real problem
Some technicians do the work. They get up in the roof, find a compliant spot within 12 metres, run the cable, and leave you with a proper install. That's what the guidelines intend.
Others look at the same job and decide it's too hard. They offer the easiest possible location — the garage, the front hallway, wherever the cable reaches with minimal effort — and if you want anything better, suddenly it's a pathway problem and it's your cost.
We've seen it repeatedly: a home where NBN did a full install with the NTD in a sensible location, and a near-identical home two doors down where the homeowner was told a pathway was required. The difference wasn't the property. It was who turned up.
This isn't a conspiracy. It's a large contractor workforce with inconsistent supervision, variable time pressure, and technicians who range from excellent to "that'll do." But the effect on you is the same: you get less work for the same upgrade, and you're asked to pay for the gap.
What "push back" actually looks like
You don't need to be aggressive. You need to ask the right question.
When you're told you need a customer-installed pathway, ask:
"What is the free option within the 12-metre radius that meets NBN's installation guidelines?"
If the answer is "there isn't one," ask them to explain why. Which specific guideline fails? Is it power access? Wall construction? Roof access? If they can articulate a genuine constraint, fine — that's a real non-standard install. If they can't, you've got grounds to escalate to your retail provider, who can raise it with NBN on your behalf.
The other thing worth knowing: NBN's fact sheet says if you're unsatisfied with the proposed option, you can install your own pathway at your own expense. That's the choice. It's not a requirement imposed on you — it's an alternative if you want something better than the free option.
Sometimes the technician just hands you the cable
There's a middle option that comes up often, and it's worth understanding because it's usually cheaper than a full conduit pathway.
Some technicians will leave you the fibre cable and tell you to have it installed by a registered cabler yourself. No conduit, no pathway — just the cable, and the instruction to get it run to where the NTD needs to go.
This is cheaper than a customer-installed conduit pathway for the obvious reason: you're not paying for conduit, trenching, or wall penetration work. You're paying a cabler to run a cable that's already been supplied.
It's also legitimate in many cases — but there are two things to watch.
First, it has to be installed properly. Bare fibre cable run without protection is exactly the fragile situation we warned about earlier. It needs to be protected from being stepped on, from rodents, and from anything that might crush or kink it. A cabler who knows what they're doing will run it safely. A cabler who doesn't will leave you with a cable that fails in six months.
Second, it's not the same as a pathway install. If the cable needs to get from the outdoor box to a spot that requires conduit for compliance — through a wall, along an exterior run, underground — handing you a loose cable doesn't solve that. It just moves the problem to your cabler.
We're happy to install NBN-supplied cable when that's the situation. We'll tell you honestly whether it's a straight run or whether you're going to need conduit anyway, and we'll protect the cable properly so it lasts. What we won't do is run a bare cable through a roof cavity and call it done.
Where we'd rather you spend the money
Here's the part most installers won't tell you: in most homes, the pathway isn't the problem. The Wi-Fi is.
A cable pathway gets the fibre to one spot in your house. If that spot is the garage or the hallway cupboard, you've now got a fast connection in the worst possible place for Wi-Fi coverage. You've paid for a pathway, and you still can't get a signal in the back bedroom.
In a lot of cases, the smarter spend is:
Take the free NTD location the installer offers — even if it's not where you wanted it
Run CAT5e/CAT6 Ethernet from the NTD to a better spot for your router, or
Install Wi-Fi access points (one or more, wired back to the router) so coverage reaches the whole house properly
A wired access point in the back of the house will beat a relocated NTD every time, and it usually costs less than a pathway install. It's also a better outcome: you're not just moving the problem, you're solving the coverage.
We install pathways when they're genuinely required — P20 conduit, draw string, compliant with NBN standards. That's real work and sometimes it's the only option. But if the choice is between paying for a pathway to move the NTD somewhere marginally better, or keeping the free install and spending the same money on proper Wi-Fi coverage, we'll recommend the Wi-Fi every time.
What TechTV does differently
When we assess a pathway job, we start by checking whether a free option was actually explored. Sometimes the homeowner has been quoted for a pathway when a simpler solution — keeping the free NTD location and running Ethernet to a proper access point — would have solved the actual problem for less.
We install pathways when they're genuinely required. But we'd rather tell you the free option exists than sell you a pathway you don't need, and we'd rather sell you good Wi-Fi than a cable run that doesn't fix your coverage.
If you've been told you need a cable pathway and you're not sure why, get in touch. We'll tell you honestly whether it's a legitimate requirement, whether you've got grounds to push back, and whether your money is better spent on coverage instead.
