Guide · NBN connection types & speed
FTTN, FTTP or HFC? Find out your NBN connection type and if you can go faster.
Here's the part most people miss. The technology that reaches your home sets your top speed before you choose a single plan. Two houses on the same street can be on different NBN types, and one might be stuck at a ceiling the other blew past years ago. So before you shop for a faster plan, find out what you're working with. Below: how to check your connection type, what each one can really do, and how the free full fibre upgrade actually works.

Why the technology matters more than the plan
Your NBN plan is a speed tier you buy. Your connection type is the physical technology in the ground and on your wall. The technology comes first, and it decides how fast the plan is even allowed to go.
Think of it like a road. The plan is the speed limit sign, but the connection type is the road itself. You can post a higher limit all you like; a narrow gravel lane still won't move traffic like a motorway. Buy a top tier plan on a line that can't reach it and you're paying for a sign nobody can obey.
That's why the smart order is technology first, plan second. Once you know your connection type, the whole speed question stops being guesswork and turns into a short, honest calculation.
How to find your connection type
Three ways to get a straight answer, from fastest to most certain.
Run the address check
The NBN website has an address lookup that names your technology in seconds. Type in your street address and it tells you whether you're on fibre, node, HFC or one of the others. This is the quickest and it costs nothing.
Read the box on the wall
Hardware is a giveaway. An NBN connection box mounted inside usually means some form of fibre. A plain old phone socket doing the work, with just a modem plugged in, often points to node. It's a clue, not proof, so pair it with a proper check.
Ask your provider
Your current internet provider knows exactly what technology serves your account and can read it back to you. If the address check ever leaves you unsure, one call settles it and confirms what you're actually connected on today.
The connection types, in plain English
There are a handful of NBN technologies, and the whole difference comes down to how far the fibre travels before it hands off to something slower. The more fibre, the higher your ceiling.
- FTTP, fibre to the premises. Fibre runs the whole way into your home. This is the top of the tree: it carries the fastest plans on offer and stays steady under load. If you're on FTTP, your connection type is not the thing holding you back.
- FTTN, fibre to the node. Fibre reaches a cabinet in your street, then copper covers the last stretch to your door. That copper is the catch. The further you live from the node, the lower your speed ceiling, and no plan can lift it past what the line allows.
- FTTC, fibre to the curb. Fibre goes almost all the way, to a small pit near your property, with only a short copper run left. Better than node in most cases, and often first in line for a full fibre upgrade.
- HFC, hybrid fibre coaxial. Fibre to your neighbourhood, then the coaxial cable once used for pay TV into the home. It can reach high speeds, though performance can dip when the whole street is busy at night.
- Fixed wireless and satellite. Used where cable is impractical, mostly rural and remote homes. Speeds are lower and more weather-sensitive, but for those addresses it's the connection that makes the NBN reach at all.
The single most useful thing to know: if you're on FTTP or HFC, technology is rarely your limit. If you're on FTTN, it often is, and that's exactly where an upgrade can change everything.
What each type can realistically do
A rough guide, because real speed depends on your line, not just its label.
Treat these as broad shapes, not promises. Two homes on the same FTTN node can get different real speeds because one sits closer than the other. The label tells you the ceiling; your own line tells you how close to it you'll get.
The free full fibre upgrade, explained
Here's the question worth its own section, because it's the one that saves people real money. If you're on FTTN or FTTC in an eligible area, you can often have full fibre run to your home at no charge for the standard install.
The catch is fair rather than sneaky. NBN Co covers the standard install cost when you commit to a fast enough plan, so the fibre itself is free but you agree to sit on a higher speed tier for a period. For a lot of homes that trade is well worth it: you shed a copper ceiling you were never going to beat and gain a connection that's steadier under load.
The order of play matters. Check whether your exact address is upgrade-eligible, then order the upgrade through an internet provider rather than approaching NBN Co directly. The provider arranges the build, the appointment and your new plan in one go. Eligibility runs address by address, so a neighbour qualifying is encouraging but not a guarantee for you.
When a slower connection is holding you back
Some signs point straight at the technology rather than the plan. Video calls that stutter when someone else streams, evening speeds that sag well below the day, or a top tier plan that never seems to feel top tier. On FTTN especially, that's often the copper talking, not your provider.
Before you blame the line, rule out the easy stuff. Old WiFi hardware, a modem tucked in a cupboard, and tired in-home wiring all steal speed no matter how good your connection type is. Run a wired speed test straight into the modem to see what your line alone delivers, then compare it against the tier you're paying for.
If the wired result still falls short of the tier and you're on copper, that's your answer. You're paying for speed the technology can't hand over, and either a lower tier or a fibre upgrade will serve you better than another dollar on the current plan.
Match the plan to the line, not the wish
The mistake we see most often is buying the tier you want instead of the tier your line can reach. It's an easy trap, because the faster plan is right there and only costs a little more. On copper, that little more can buy you nothing at all.
So flip the order. Confirm your connection type, then choose a speed tier the technology can genuinely deliver. If you're on FTTP or HFC, feel free to chase the fast tiers; the line will keep up. If you're on FTTN and near the far end of your node, a mid tier you can actually hit beats a premium tier you can't.
- Know your ceiling first. Your connection type sets the maximum. There's no sense paying for a tier above what the line allows.
- Test before you upgrade the plan. A wired speed test tells you where your line sits today, so you can see whether a faster tier would even show up.
- Ask about the fibre upgrade before the plan. If free full fibre is on the table, that changes the whole calculation, so check it before you lock in a copper-limited tier.
Five minutes of checking beats years of quietly overpaying for speed your line was never going to give you.
Questions people ask
How do I find out what NBN connection type I have?
The quickest way is the address check on the NBN website, which names your technology in seconds. If you would rather not use it, the box on your wall is a strong clue: an NBN connection box inside the home usually means fibre, while a plain phone socket doing the work often means node. Your provider can also tell you from your account.
What is the difference between FTTN and FTTP?
FTTP, fibre to the premises, runs fibre all the way into your home, so it carries the fastest plans on offer. FTTN, fibre to the node, runs fibre to a cabinet in your street and then copper for the last stretch, and that copper caps your speed. The further you sit from the node, the lower the ceiling.
Can I get a free upgrade to full fibre?
Often yes, if you are on FTTN or FTTC in an upgrade-eligible area. NBN Co covers the standard install cost when you sign up to a fast enough plan, so the fibre itself is free but you commit to a higher speed tier. Check eligibility for your exact address, then order the upgrade through a provider, not NBN Co directly.
Why is my NBN slower than the speed I pay for?
On copper technologies like FTTN, the line length and condition can hold you below your plan's tier, no matter what you pay. On any technology, evening congestion, old WiFi hardware and in-home wiring all drag real speeds down. If your line simply cannot reach the tier, you may be paying for speed the technology cannot deliver.
Does upgrading my plan speed change my connection type?
No. Buying a faster plan changes the speed tier your provider sells you, not the physical technology at your address. If you are on FTTN and the copper cannot reach that tier, a dearer plan just wastes money. Check your connection type first, then buy a tier your line can actually deliver.
Is it worth upgrading from FTTN to fibre?
For most homes that stream, work from home or have several people online at once, yes, because fibre lifts the speed ceiling copper cannot reach and tends to be more stable. If one person browses lightly and your FTTN line already hits its tier, the gain is smaller. Weigh your real usage before you commit to a higher ongoing plan.
Paying for speed your line can't reach?
