How to Check Your NBN Connection Type
A practical guide to checking NBN technology at an address and understanding what it means for speed and equipment.

Your NBN connection type is the last part of the network that reaches the premises. It can affect which speed tiers are available, what equipment is installed and where a fault may occur.
The reliable way to check it is an address-level lookup. Use the CompareUs NBN availability preparation tool to organise your household needs, then confirm the technology with the official NBN address checker or a retail provider.
What the connection labels mean
- FTTP, or Fibre to the Premises, runs fibre into the property and uses an NBN connection box.
- HFC, or Hybrid Fibre Coaxial, uses the pay-TV style coaxial cable for the final connection and an NBN connection box.
- FTTN, or Fibre to the Node, uses copper from a nearby node to the premises.
- FTTC, or Fibre to the Curb, brings fibre close to the property, with a shorter copper section and an NBN connection device.
- FTTB, or Fibre to the Building, commonly uses fibre to a shared building point and existing cabling to individual premises.
- Fixed Wireless and Sky Muster use wireless or satellite links for eligible regional and remote premises.
NBN Co provides its own overview of how the network connects homes, while the provider confirms what it can sell at the address.
Check the hardware already at home
An NBN-labelled connection box is a clue, but it is not a substitute for a current address check. Equipment may have been left by a previous resident, and the property may have since become eligible for an upgrade.
FTTP and HFC services normally involve an NBN connection box. FTTN and FTTB services commonly connect through a compatible VDSL modem-router. FTTC uses an NBN connection device between the wall socket and router. If the boxes and cables are confusing, photograph the labels before contacting a provider.
Why connection type matters
Eligible FTTP and HFC premises can access the newer accelerated wholesale tiers, including 500, 750, 1000 and 2000 Mbps options. Retail availability and typical evening speeds vary. FTTN performance can be more affected by the length and condition of the copper line.
That does not mean every fibre plan will feel perfect. Router capability, Wi-Fi coverage, device hardware and provider performance still matter. Run an internet speed test over Ethernet before diagnosing Wi-Fi or choosing a faster tier.
Use the result when comparing plans
Once you know the technology:
- Check the speed tiers offered at the exact address.
- Compare typical evening download speeds and upload specifications.
- Confirm whether new hardware or installation is required.
- Read the current Critical Information Summary.
- Compare ongoing cost after any introductory offer.
The provider has the final say on live serviceability. NBN Co's preparing to connect guidance also explains why existing NBN equipment should generally remain at the premises when people move.
If several tiers are available, use the NBN speed tiers guide. The connection type tells you what may be possible; your household use and budget decide what is sensible.

FAQs
How do I find my NBN connection type?
Use NBN Co's official address checker or a provider's live serviceability check. Your existing connection box and provider account may also identify the technology.
Which NBN connection type is fastest?
FTTP has the broadest high-speed capability. Eligible HFC can also access accelerated tiers, while other fixed-line technologies have different physical limits.
Does an NBN address check guarantee a plan is available?
No. It is a strong starting point, but the retail provider must confirm serviceability, plan eligibility and any installation requirements.
Can my NBN connection type change?
Yes. Some premises may become eligible for a fibre upgrade. Check the official address result and provider options rather than relying on an old bill.
