nbn Fixed Line

This page provides information about the “Fixed Line fibre”, also called “fibre-optic”, connections provided by nbn Co.

While these connections are mainly found in Australia’s big cities, some large regional towns in Australia also have access to this network.

What is nbn™ Fixed Line fibre?

nbn™ Fixed Line

Picture with text. Text reads: nbn™ Fixed Line. Your internet and phone connection uses fibre-optic line or coaxial cable to connect to the indoor modem, which routes the internet to all your devices (laptop, desktop, phone, desktop, weather station, and so on).

nbn ™ Fixed Line services use fibre-optic cables in the ground to deliver both internet and voice (ordinary phone) services. This is the big rollout being performed around Australia. You can see what nbn™ technology (nbn™ SkyMuster satellite, nbn™ Fixed Wireless or nbn™ Fixed Line) is available at your location by visiting the nbn rollout map and toggling on “Show service type”.

All types of nbn access network connections that utilise a physical line running to the premises (FTTP, FTTB, FTTC, FTTN, and HFC – see below) are considered Fixed Line connections.

The difference between them is how the connection gets from the main fibre-optic network to your premises.

If you have access to the Fixed Line network, you will have access to a very broad range of connection plans, speeds, and prices.

When nbn™ Fixed Line fibre is installed in a region, the existing copper-based phone network will be turned off within 18 months. This will impact any phone and internet services (such as ADSL) you currently have. You must sign up to an nbn™ plan to continue receiving voice and internet services; they will not be automatically switched across.

Can I get nbn ™ Fixed Line fibre?

Use the nbnrollout map to find what nbn™ services are available in your location.

This will identify what nbn services are in your region.

The nbn™ fibre network must have been rolled out to your region for you to connect directly to it.

If your address doesn’t map or maps incorrectly you can contact a provider, or fill in our desk check form and we can assist in getting it fixed.

Connection types overview


An nbn™ Fibre to the Premises (FTTP) connection is used in circumstances where a fibre optic line will be run from the nearest available fibre node, directly to your premises.

FTTP connections require an nbn access network device to be installed inside your home. This device requires power to operate (some providers offer battery back-up devices) and can only be installed by an approved nbn installer.

A Fibre to the Premises (FTTP) connection uses fibre optic cables to connect your home or business directly to the nbn ™ network. Voice only plans are available on FTTP, with certain providers.

For more information, visit the nbn™ FTTP web page.


With a Fibre to the Building connection, an nbn™ fibre optic cable is laid directly to the bottom of your building, where it connects to the copper phone line that runs into your apartment or office.

An nbn ™ Fibre to the Building (FTTB) connection is generally used when providing a connection to an apartment block or similar types of building. nbn runs a fibre-optic line to the fibre node in the building’s communications room, and then uses the existing technology in the building to connect the internet to each apartment.

The fibre node is likely to be found in a secure cabinet in your building’s communications room.

For more information, visit the nbn ™ FTTB web page.


With a Fibre to the Curb (FTTC) connection, an nbn ™ fibre optic cable is laid directly to your property’s kerb or driveway, where it connects to the copper phone line that runs into your home.

An nbn ™ FTTC connection is used in circumstances where fibre is extended close to your premises, connecting to a small Distribution Point Unit (DPU), generally located inside a pit on the street. From here, the existing copper network is connected to the fibre to form the final nbn  connection. To power your FTTC service with electricity and provide your connection to the nbn™ broadband access network, an FTTC nbn ™ connection box will be required inside your home or business. You may be able to install the connection box yourself.

For more information, visit the nbn™ FTTC web page.


With a Fibre to the Node (FTTN) connection, an nbn™ fibre optic cable is laid to a central cabinet in your neighbourhood (the node). From there, it connects to your house or business using existing copper wiring. The speed you get will be determined by a range of factors such as how many people use your connection, and how you typically use the internet in your household.

An nbn™ Fibre to the Node (FTTN) connection is used where the existing copper phone and internet network from a nearby fibre node is used to make the final part of the connection to the nbn™ access network.

The fibre node is likely to take the form of a street cabinet. Each street cabinet will allow the nbn™ access network signal to travel over a fibre optic line from the exchange, to the cabinet, and connect with the existing copper network to reach your premises.

For more information, visit the nbn™ FTTN web page.


HFC stands for “Hybrid Fibre Coaxial”. It’s used where an existing pay-TV (Foxtel) or cable network (Telstra or Optus) is available. There is no nbn™ HFC in regional areas.

For more information, visit the nbn™ HFC web page.

Understanding fixed line plans

Plans are supplied by individual internet service providers.

You can either check individual plans on the suppliers’ websites, or use a comparison site such as:

Note that while useful, comparison sites may be funded by providers advertising fees. They may not provide a comprehensive review of all available services in your area.


nbn™ fixed line speeds come in six speed tiers:

Common name nbn name Download speed Upload speed
NBN 12 Home Basic I 12Mbps 1Mbps
NBN 25 Home Basic II 25Mbps 5 Mbps
NBN 50 Home Standard 50Mbps 20Mbps
NBN 100 Home Fast 100Mbps 20Mbps
NBN 250 Home Superfast 250Mbps 25Mbps
NBN 1000 Home Ultrafast 1000Mbps 50Mbps

The faster speed tiers may only be available in central metropolitan areas, on certain nbn™ Fixed Line technologies, or with a business-grade connection. For more information about business broadband, see Business.
