nbn® Hybrid Fibre Coaxial (HFC) explained


nbn HFC made easy

All types of nbn network connections that utilise a physical line running to the premises are considered Fixed Line connections.

An nbn Hybrid Fibre Coaxial (HFC) connection is used in circumstances where the existing ‘pay TV’ or cable network can be used to make the final part of the nbn network connection. In this circumstance an HFC line will be run from the nearest available fibre node, to your premises.

HFC connections require an nbn network device to be installed at the point where the line enters your home. This device requires power to operate.


nbn Hybrid Fibre Coaxial (HFC) installation

There are two ways HFC can be installed at your premises – through an nbn approved installer or if eligible, through self-installation.

When you contact your phone and internet provider to connect to the nbn network, they will confirm which installation process applies to your premises.

Installation with an nbn approved installer

Your phone and internet provider should arrange for an nbn approved installer to call you and organise a visit to your premises to connect you.

[Narrator] Congratulations on switching to the NBN network. This video will walk you through installing your NBN-supplied equipment without pay TV or existing cable internet. If you have either of these, refer to the video for installation with pay TV. 

You will need the following equipment from your NBN connection kit: an NBN connection box, a white cable, a black power adapter, and an NBN sticker.

First, locate your cable wall outlet inside your premises. It will look similar to one of the examples shown. Using the NBN white cable, screw one end into the wall outlet and the other end into the white panel on the back of your NBN connection box.

Next, insert the black NBN power adapter into the black power port, and plug the other end into a power outlet. Switch on the power to start up your NBN connection box. It may take up to ten minutes for it to activate.

If you don't get solid green lights on your NBN connection box, check that the white cable is connected securely. If it is, try another wall outlet. If this doesn't work, contact your service provider.

Once you get four green lights on your NBN connection box, you can stick the NBN sticker to your cable wall outlet to identify it in the future.

You can now connect your own or your service provider's router. Plug one end of your ethernet cable into the yellow data port marked "UNI-D1," then plug the other end into the router. You can now power up the router to start enjoying your connection to the NBN network. Solid lights on the front panel may indicate your router is working. If you have any issues, contact your service provider.

Your devices can connect via Wi-Fi to your router. To connect your router via ethernet cable to your home phone or other equipment, see your service provider's instructions. All of this information, along with a few troubleshooting tips, is covered in your NBN setup guide.

Self-installation for eligible premises

Play our nbn HFC Connection Box, Self-Installation video (duration 4:42) to install your nbn supplied equipment.


Due to the maturity of the HFC roll-out and changes in the delivery of Pay TV services, nbn has determined that the splitter and additional cable are no longer required. Hence, there will only be a self-installation video without Pay TV.

To ensure you can enjoy the best possible experience on the nbn network, you are receiving a new nbn connection box.

This video will take you through how to disconnect your existing nbn connection box if required, and set up a new one.

Firstly, if you have an existing nbn connection box, let's disconnect it. Start by locating it inside your premises. It might look similar to this. Switch off the power at the outlet.

Next, unplug the power adapter from both the outlet and the back of the existing nbn connection box.

Next, disconnect the Ethernet cable from the Ethernet port on the back of the connection box and from your Wi-Fi router.

If your nbn connection box cable looks like this, unscrew the white cable from the wall outlet and from the white panel on the back of the nbn connection box.

If your nbn connection box cable looks like this, you'll need to unlock the connectors on the fixed white cable. To do this, insert a small object into the hole on the connector and press down firmly to release the locking mechanism. While keeping pressure applied, turn the connector lock anti-clockwise until it loosens and can be removed.

Once all cables are disconnected, gently remove the existing nbn connection box. Now you're ready to install your new nbn connection box.

It's important to note that you should not re-use any parts from your old nbn connection box, including the power adapter or cables. Instead, you'll need the following equipment provided in your nbn self-install kit: a new nbn connection box, a fixed white cable and a power adapter.

The following equipment is also required to get online but is not included in your nbn self-install kit: A Wi-Fi router, a Wi-Fi router power cord, and an Ethernet cable. These items may be provided by either yourself or your internet provider.

To install your new nbn connection box, locate the wall outlet inside your premises. It will look similar to this. Using the supplied fixed white cable, connect one end into the wall outlet and the other end into your nbn connection box. Check that the fixed white cable is connected correctly and securely.

Next, insert the power adapter into a power port on the nbn connection box. Plug the other end into a power outlet, then switch on the power to start up your nbn connection box. Allow 30 minutes for the device to be configured and connected to the network.

After 30 minutes, if any of the lights are not solid green, ensure that the white cable is securely connected. If it is, and it's been 30 minutes, switch the power off and then on. If this doesn't work, contact your internet provider.

Once you get four solid green lights on your nbn connection box, you can connect to your own Wi-Fi router or a Wi-Fi router supplied by your internet provider.

Plug one end of your Ethernet cable into the Ethernet port on the back of your new nbn connection box. Then plug the other end into your Wi-Fi router. You can now power up the Wi-Fi router to start enjoying your connection to the nbn network.

Solid lights on the front panel may indicate your Wi-Fi router is working. If you have any issues, contact your internet provider.

Your devices can connect to your Wi-Fi router via Wi-Fi. To connect to your Wi-Fi router via an Ethernet cable to your home phone or other equipment, see your internet provider’s instructions.

Your new nbn connection box may have a QR code on the front, which you can scan for troubleshooting information.

All of this information, along with troubleshooting tips, is included in your nbn setup guide and available at nbn.com.au/hfc

Once your new nbn connection box is ready to go, we suggest also checking that your in premises internet equipment is set up to get the most out of your nbn connection. For more information, visit nbn.com.au/optimise

Did you know that you can return old nbn connection boxes to nbn for free? Alternatively, if you've mistakenly removed nbn equipment from another premises, you can return it to us at no cost to you.  Simply visit return.auspost.com.au/nbnco to create a return label. Then follow the instructions to get your return label printed before taking your old nbn connection box and any accompanying cables to the nearest Australia Post location to drop it off.

Frequently asked questions


The nbn connection box is the property of nbn. It should not be moved from its location at the time of installation without permission from nbn and support of an nbn technician.

It is preferable that you do not try to remove the fixed white cable from the device to minimise risk of damaging your nbn supplied equipment. However, if you must temporarily do so, the lock connectors can be removed from the port with any small object that will fit into the hole in the connector.


To remove the lock connector:

  1. Insert a small object, such as a papeclip, into a hole on the connector lock and press down firmly to release the locking mechanism
  2. While maintaining pressure, turn the connector lock anticlockwise until it loosens and can be removed

The nbn connection box is considered electronic waste (e-waste) and cannot be disposed of in your kerbside rubbish bins. Instead, it needs to be taken to a specialist e-waste recycling location, or sent back to nbn via Australia Post. This ensures the valuable materials in the device are recovered to make new products, and keeps hazardous chemicals out of the environment. You can find your nearest e-waste recycling location using Recycle Mate. Locations can include local council resource recovery centres and local libraries.

We have partnered with Australia Post allowing for devices to be sent back to us with a label you can access online at no cost to you. For more detais, visit the Australia Post website. You may have received an Australia Post reply paid satchel with your new nbn connection box which you can use to return your old nbn connection box.

After your phone and internet provider confirms your order, an appointment window will be scheduled and confirmed by us via SMS, please reply to this message with your preference. You will receive a call a few days before your installation appointment to confirm that all the requirements are ready – and to make sure that there will not be any access restrictions at the site on the day.

Note: You will need to call your provider if you wish to make an appointment outside of the appointment window or reschedule an existing appointment.

On the day of installation an nbn technician will visit your premises to complete the following tasks:

  1. Determine and discuss with you the location(s) to mount/install nbn supplied equipment.
  2. If necessary, install a lead-in cable from the street to your property.
  3. Install, activate and test the installed nbn supplied equipment.
  4. Clean up after they have finished the installation.

The installation may include ducting and drilling works. If your premises has a communications cabinet, access will need to be arranged with your building or property manager before your appointment. If you know of any nbn supplied equipment currently on site, be sure to let your provider know before the day.

A standard installation may take two to four hours. If there are complexities or if the coaxial cable is not connected to the nbn utility box (also referred to as a ‘PCD’), the installation may take longer – sometimes up to eight hours.

Yes. Someone over the age of 18 must be present at the premises for the entire duration of the installation.

Yes. If you wish to reschedule an installation, you will need to call your provider at least 24 hours before your scheduled appointment to avoid any applicable charges.

Please note that you cannot reschedule an appointment via SMS.

Technicians aim to have all the required work completed in a single visit. Due to the complex and limiting nature of connecting some types of premises, there is the possibility that your technician may have to schedule an additional visit on another day to complete the installation.

Before your technician arrives, it is important to consider the possible internal (and external) mount and install locations of the nbn supplied equipment (nbn connection box and Power Supply Unit) – your technician will help advise where they can be installed. Be sure to discuss the location with your technician before they begin.

Things to consider when choosing the location of your nbn supplied equipment:

  • No more than 80cm away from a power point – the equipment will need to stay plugged in.
  • A cool, dry, ventilated area (not a damp or wet area such as a kitchen, bathroom, laundry or under a window that opens).
  • Away from busy areas where it could be knocked or damaged.
  • Somewhere easy for you to access and check the indicator lights.
  • In the same building as the main electric meter box or distribution board (i.e. not in a detached garage).

If available, you may request to move the location of your main wall outlet free of charge as part of the installation process – you will then have two functioning wall outlets. The nbn connection box will be connected and activated on the new outlet, and the existing (old) outlet will continue to work if needed in the future.

You will be required to approve all aspects of the installation before the technician starts, so take the time to think about the install location(s). If you are not happy with all of the proposed locations or need further assistance, advise your technician that you do not want to progress with the installation and then contact your provider to discuss your options.

No, this step usually involves a simple self-installation – your provider will supply you with the instructions to complete this step. You will need to connect the provider-supplied modem to the yellow connector on the rear of the nbn connection box. Contact your provider if you need any help completing this step.

If you’re renting, you need to make your landlord aware that you want to install the required equipment, to ensure they do not object. If you’re not in direct contact with your landlord, contact your property manager or real estate agent.

To help you prepare for the switch to the nbn broadband access network, we've prepared a guide on what you need to consider.

When your technician has finished the installation, you should be able to self-install the provider-supplied modem and access your service – connecting the modem they have supplied you to the yellow connector on the rear of the nbn connection box.

The service activation process:

  1. We will notify your provider that your installation has been initiated.
  2. Your provider will then provision your service.
  3. Your technician finishes your installation – testing and activating your service.
  4. You can then self-install the provider-supplied modem – connecting the modem to the yellow connector on the rear of the nbn connection box.
  5. You’ll need to wait up to 30 minutes after setting up your connection box for all four lights on your connection box to turn solid green. If any of the lights are not solid green, check that the cables are connected correctly and secure. Then switch the power on and off.

If you encounter any issues activating your service, you will need to contact your provider for assistance.

You’ll need our latest nbn connection box to support 2 Gbps plans. You should speak to a Retail Service Provider to find out whether an equipment upgrade is required.

A Wi-Fi router is a box that connects your home to the internet and lets your devices — like phones, laptops, and TVs—use that internet wirelessly. For tips on how to optimise your internet set-up (including Wi-Fi), visit the Optimisation hub.

nbn technicians do their best to keep every appointment and notify customers if they can no longer make the agreed time. On the rare occasion that a technician is delayed due to the complexities of another installation and misses your appointment, you will need to contact your provider to reschedule your appointment.

If you have a complaint regarding your installation experience, please contact us.

If the requirements of the installation are ‘non-standard’, your technician will refer you to contact your provider to discuss options and/or potential charges that may be involved. There are some cases where you may be required to organise and pay for digging a trench to prepare your premises to connect to the nbn infrastructure.

Guidelines on the removal or relocation of nbn supplied equipment can vary depending on the situation. If you’re planning on removing or relocating your equipment due to renovation or demolition, before you do, please visit our relocation/removal page for more information.



If you're moving, you should leave the nbn supplied equipment at your old premises.

Any nbn supplied equipment, including the nbn connection box (also known as the Network Termination Device (NTD)), should stay at the current address – please do not take it with you. The nbn equipment is registered to the specific address, therefore will not work or be compatible with your new premises. You won’t be able to use it at your new address, and it cannot be re-sold as it is property of nbn.

Back of black Network Termination Device (NTD) unit featuring a Reset button and cable ports.

Additionally, by removing the nbn supplied equipment, you may make it harder for the new owner or occupant of the premises you’re moving from to connect to the nbn network.

If you have mistakenly removed nbn equipment from another premise you can return it to us at no cost to you. We have partnered with Australia Post allowing for devices to be sent back to us with a label you can access online. Simply print a return label and read the instructions on how to return the equipment, postage paid and at your convenience.
