NBN HFC plans

Depending on where you live, you might be eligible for speeds up to 1000Mbps with an HFC NBN plan.

Hybrid Fibre Coaxial (HFC) might be a mouthful to say, but if you've got this NBN connection type, you're in for a chance at speeds of up to 1000Mbps which is the fastest NBN speed currently available in Australia.

You'll need to double check your address before signing up to these Ultrafast plans to see if your house is eligible.

What is HFC NBN?

HFC connections use a mix of existing pay TV coaxial cables (the same ones that deliver Foxtel) and high-speed fibre optics.

Whether you have it or not depends on where you live, but chances are you'll get it if there is existing cable TV or cable Internet from Optus or Telstra in your neighbourhood.

Signals are sent from your house to a nearby node through coaxial cables, then switched to the wider fibre network of the NBN. A modem in your house completes the connection.

NBN Co is temporarily limiting new HFC connections to the NBN

This means that if your property is connecting to the NBN for the first time using this technology, you'll have to wait a few months as NBN Co sorts out a global supply chain issue. It's expected that new connection orders for HFC customers will go back to normal at the end of May or early June 2021.

What are HFC NBN speeds like?

Every HFC connection should be capable of achieving NBN 100 speeds; that is, download/upload speeds of 100/40Mbps. But if you're trying to get one of the two new higher-speed plans, NBN 250 or NBN 1000, it will depend on where you live as to whether you can sign up to these plans.

Only 70% of HFC NBN customers can get an NBN 250 connection, and just 7% are eligible for NBN 1000. NBN Co has promised a network upgrade so that all HFC customers can order NBN 1000 by the end of 2021, but for the moment, you might have to settle for something slower.

Like any other fixed line connection, your cable Internet will slow down during busy periods of the day, especially in the evening between 7pm and 11pm.

What equipment do you need for HFC NBN?

The equipment required for cable Internet is more or less the same as any other NBN connection:

  • An NBN connection box – provided by the NBN
  • An NBN utility box – provided and installed by the NBN
  • A modem-router – purchased from your Internet service provider or a third party

Finally, if you also have a pay TV subscription, you'll need a cable splitter (provided by the NBN), which lets you attach both your modem and pay TV box to the same wall outlet.

How is HFC NBN installed?

The utility box outside your house is installed by NBN Co, and you don't have to worry about it. If your property is a new development, the technician will require access to your outdoor area to install the utility box. If you live in an apartment, check with your provider if the NBN connection box isn't already installed in your unit.

All you need to do is plug your NBN connection box into the coaxial wall outlet using the provided cable, and then attach your modem-router to one of the box's yellow UNI-D ports with an ethernet cable (provided with the modem). You'll also need a couple of spare power outlets for both devices.

How does HFC compare to other connection types?

HFC is just one of the many NBN technology types. While you can't exactly choose the type of NBN connection type you get at your home, it can be good to know how it stacks up compared to other types just so you know what to expect.


Both connection types run to a central node before connecting to the wider network. However, Fibre to the Node (FTTN) uses inferior copper telephone cables instead of HFC. This means your FTTN connection gets significantly worse the farther you are from the node.

  • End result: FTTN is generally less reliable and slower than HFC.


With Fibre to the Curb (FTTC), copper connects your home to a distribution point or "telecom pit" near your house, and from there fibre optic completes the connection to the greater network. Copper is still worse than HFC, though, so FTTC suffers.

  • End result: HFC and FTTC are pretty similar, although HFC is usually better.


Fibre to the Premises (FTTP) is the best NBN connection type available, where high-quality fibre optic cables are run all the way up to your house. FTTP is unparalleled for speed and performance.

  • End result: FTTP is the best NBN connection available and easily outperforms HFC.


In a Fibre to the Basement (FTTB) connection, fibre optic cables are run to a box in the basement of a building, and from there other cables complete the connection to individual apartments. Similar to FTTN, apartments further from the basement will experience worse connections.

  • End result: HFC and FTTB can be pretty comparable, depending on the building.

    Hi Team

    Your finder.com information provided on Broadband services in general is clearly explained, unbiased and informative. However, a confusion exists in your advertised cost for the Bundle package called, (Telstra Home Internet M Bundle – Cable with Speed Boost for $110 with up to 100 mbps and unlimited calls to standard local and national fixed lines and standard Australian mobiles.)

    When you click on your ‘Go to site’ link next to your advertised bundle on your site, the information found on the linked telstra site does not offer Speeds up to 100mbps for your advertised price of $110.

    You might want to clarify if your details are correct or my details obtained by selecting the same options on the telstra shop site are more than you quote of $110 (a speed boost from 25 mbps to 100 mbps is an add-on cost of $20/mth and the included calls cost more – $15/mth, taking the cost up to between $126 and $146(if a Netgear Frontier modem is needed).

    Can you please clarify if I am correct? Thanks

      Hello Tango!

      Speeds of up to 100mbps is a maximum hypothetical speed that can be attained using HFC cable technology. Most telco providers in Australia will have the same disclosure on this matter. Speeds are never guaranteed as they are affected by multitude of factors such as your distance to the exchange, technical limitations, the bandwidth demand in your area, devices connected, etc.

      If you wish to understand this better, you may check the Critical Information Summary or talk this out with your network provider.

      Hope this helps.
