Do I Need to Redo My Home Wiring for NBN FTTP? A Newcastle Guide

When Newcastle residents get their NBN fibre upgrade letter, we get one question more than any other: 'Do I need to rewire my whole house?' The short answer is almost always no. But there are a few smart, low-cost upgrades that make a big difference.

What NBN does (and doesn't do)

NBN Co installs one outdoor box, one indoor box, and terminates the fibre — usually in one room. That's it. Everything past the NBN Connection Box — your Wi-Fi, Ethernet outlets in other rooms, the phone jack — is your responsibility.

When you don't need to do anything

• You're happy with the router living in the same room as the NBN box.
• Your Wi-Fi covers the whole house without dead spots.
• You don't use a copper landline phone.
• You have no alarm or lift phone connected to the old telephone wiring.

When a local cabler pays for itself

If your NBN Connection Box is going to be installed in your garage, hallway or an inconvenient corner, but your family sits in the living room or a home office at the other end of the house, running one Cat6 Ethernet cable from the NBN box to a wall outlet in that living area (before install day) is by far the cheapest fix. Rewiring for FTTP is nothing like a full electrical rewire — usually one or two neat cable runs, one or two data outlets, done in a couple of hours.

Coverage upgrades — mesh vs Ethernet

For Newcastle homes larger than about 150 sqm, a single router usually won't cover the whole house on Wi-Fi. You have two choices: (1) install a mesh Wi-Fi system with a wired backhaul to a second access point in a distant room, or (2) run Ethernet to every room from a central patch panel. Ethernet is faster, more reliable and future-proof — but mesh is easier to install if you can't run cables through your walls.

What about the old phone socket?

Once copper is disconnected (typically 18 months after your FTTP install), your old phone sockets become dead. If you use a landline, you'll need a VoIP handset that plugs into your NBN Connection Box, or your internet provider's phone service. Most Newcastle homeowners just switch to mobile at this point.

Getting it right first time

The cheapest option is always to plan the cabling before NBN arrives. A single visit from a local Newcastle cabler can save you weeks of frustration and hundreds of dollars in reschedules.
