The short answer
What HFC really is, and why it is underrated
HFC, short for Hybrid Fibre Coaxial, is the NBN connection that reuses the coaxial pay-TV cable Telstra and Optus laid down the street in the 1990s, fibre running most of the way and the old cable carrying the last stretch into your home. It covers a sizeable slice of NBN premises, and most people who have it dismiss it as outdated. That is the wrong read. HFC is a shared medium, so the capacity on your local cable segment is divided among the homes that share it, which is why a busy street can dent your evening speed in a way fibre does not. But here is the part that gets missed: after the late-2025 NBN Co upgrade, most HFC lines now reach the same top tiers as fibre, pushing Fast toward 500 Mbps and Superfast toward 750 Mbps at no extra wholesale cost. This page explains how HFC actually works, why sharing matters at 8pm and not before, and why HFC is quietly one of the best-value connections in Australia where you can get it.
Here is the core takeaway in one line: HFC reuses old pay-TV coaxial cable and shares the final street segment among neighbouring homes, so a busy street can shave your evening speed, but after the 2025 NBN Co upgrade HFC now reaches the top tiers and is one of the best-value connections in Australia where it exists. That single idea fixes two mistakes people make: they write HFC off as outdated cable that cannot compete with fibre (it can, and now nearly does), and they expect it to behave like a dedicated line at 8pm (it will not, because the street shares it). Understand the sharing, and HFC stops looking like a compromise and starts looking like a bargain.
Reframe the assumption: "old cable" is not the same as slow. The coaxial run is old, but the fibre behind it is not, and that is what the 2025 upgrade unlocked. HFC now carries 500 to 750 Mbps tiers on eligible lines, leaving Fibre to the Node copper far behind. The only real trade-off is that the last segment is shared, which shows up at peak and almost nowhere else.
The blind spot
Why most HFC guides give you the wrong impression
Most explainers on HFC do one of three unhelpful things, and each one leaves you either fearing a perfectly good connection or misreading why it sometimes slows.
First, they treat HFC as second-rate "old cable". Because the coaxial run dates to the 1990s, guides quietly rank it below fibre and tell you to upgrade away from it. That advice is now stale: the 2025 upgrade lifted most HFC lines to the same top wholesale tiers as Fibre to the Premises, and HFC sits far above Fibre to the Node copper, which got nothing.
Second, they blame "the NBN" for every evening slowdown. When HFC dips at 8pm, the easy story is that the network is faulty. The real reason is structural: HFC is a shared medium, so the street's capacity is split more ways when everyone is online. That is a design feature of the technology, not a fault, and it is predictable.
Third, they confuse the two kinds of sharing. Every NBN connection shares the bandwidth your retailer buys per customer. HFC adds a second layer: the physical coaxial segment shared along your street. Most guides mention one and miss the other, so readers cannot tell whether a slow evening is the retailer skimping or the street being busy. Both feed into one published number, the Typical Evening Speed, which is why that figure matters even more on HFC.
How HFC works, piece by piece
Expert analysis: what really decides your HFC speed
Fibre to the street, coaxial to the door
HFC is "hybrid" because it stitches together two media. Fibre carries the signal from NBN Co's network most of the way to your neighbourhood and into a local node, then the existing coaxial pay-TV cable, originally laid by Telstra and Optus for services like Foxtel, runs the last stretch to your home. You get the same NBN gear as any other connection: a utility box outside, an NBN connection box inside, and your own modem. The fibre backbone is modern and fast; the coaxial tail is what makes HFC distinctive, and it is also why HFC behaves differently from pure fibre at peak.
The street segment is shared, and that is the whole story
This is the part that separates HFC from fibre. On Fibre to the Premises, your line is yours alone all the way back to the network. On HFC, the coaxial segment along your street is a shared medium: the homes connected to it draw from a common pool of capacity. During the day, when few neighbours are using much, you can sit right near your tier. From 7pm to 11pm, when the whole street streams, games and joins video calls at once, that pool is divided more ways and your speed can dip. A lightly loaded street barely notices; a dense, heavy-use street feels it most. This is normal HFC behaviour, not a fault.
Two layers of sharing, and the TES that captures both
HFC has two sharing layers stacked on top of each other. The first is the one every NBN connection has: the shared bandwidth (CVC) your retailer chooses how much of to buy per customer, a margin decision that can hold or sink your evening speed. The second is unique to HFC: the physical street segment. Both compress at the same time, the evening peak. The honest number that already bakes in both is the Typical Evening Speed (TES), the speed a retailer says you can expect from 7pm to 11pm. The ACCC Measuring Broadband Australia programme tests real homes and consistently finds HFC holds a high share of its plan speed at peak, which is exactly why HFC has a better reputation among people who measure than among people who guess.
The 2025 upgrade, and why HFC leapfrogged FTTN
The last piece is the one that flips the verdict. From late 2025, NBN Co lifted the wholesale speeds on eligible Fibre to the Premises and most HFC lines at no extra wholesale cost, pushing the Fast tier toward 500 Mbps, Superfast toward 750 Mbps and Ultrafast toward 2000 Mbps. HFC was included because the fibre backbone behind it can carry the extra speed. Fibre to the Node, whose final copper run physically limits many lines, got none of it. So in one move HFC went from "old cable" to a line that reaches the same top tiers as fibre, while copper stayed stuck. Where you can get HFC, it is now clearly better value than FTTN and close behind FTTP.

Pick how loaded your street is at peak and whether you want the 2025 speed boost, and it shows the realistic evening speed to expect on HFC plus the best-fit tier to buy. It makes the sharing trade-off concrete, the thing that actually shapes your HFC experience.
Estimate your realistic HFC evening speed
Indicative only. Always confirm the Typical Evening Speed on the actual plan, and that the boost applies to your address.
Realistic evening speed
We take the tier ceiling (raised if you apply the boost on eligible HFC), then apply a peak retention factor for street sharing: about 95% on a lightly loaded street, 88% on an average one and 78% on a heavily loaded one. Choose a plan whose published Typical Evening Speed is at or above the figure shown.
Assumptions: peak retention factors are indicative HFC averages, not a guarantee for any one street; the boost only applies to eligible HFC lines where the retailer passes it on. Prices are indicative 2026 ranges and vary by retailer. Sources: NBN Co wholesale pricing and the late-2025 speed upgrade, ACCC Measuring Broadband Australia, Canstar Blue 2026.
| Speed tier | Ceiling | Typical evening speed | Indicative price/mo | Best for |
|---|---|---|---|---|
| NBN 50 (Standard Plus) | 50 Mbps | ~45 to 50 Mbps | $70 to $80 | A small household streaming HD on a few devices; HFC holds this easily even on a busy street. |
| NBN 100 (Fast) | 100 Mbps | ~90 to 100 Mbps | $80 to $95 | A busy home with 4K streaming, gaming and working from home; the HFC sweet spot for most. |
| NBN 100 boosted (Fast) | ~500 Mbps | ~400 to 500 Mbps | $80 to $95 | The same Fast tier after the 2025 upgrade on eligible HFC, far more speed for the same price. |
| NBN 250 (Superfast) | ~750 Mbps | ~600 to 750 Mbps | $95 to $110 | Heavy users moving big files or running many 4K streams; the boosted Superfast tier on HFC. |
| NBN 1000 (Ultrafast) | ~1000 Mbps | ~250 to 700 Mbps | $110 to $130 | The top tier where the HFC segment supports it; evening speeds vary most with street load here. |
What this looks like in real homes
How HFC plays out for real Australian households
The sharing mechanics above are not theory. They are exactly how HFC households end up misjudging a connection that is usually better than they think:
The renter who fled HFC for nothing
A renter reads that HFC is "old cable", assumes it is holding them back, and pays to chase a fibre upgrade. Their HFC line was already eligible for the 2025 boost and was delivering close to 500 Mbps in the evening. They spent time and money fixing a connection that was not broken.
The dense apartment block that blamed the NBN
A unit in a busy block sees speeds dip every evening and lodges complaint after complaint about the network. The line is fine; the coaxial segment is simply heavily shared at peak. Moving to a retailer with a higher Typical Evening Speed reclaimed most of the lost speed without touching the cabling.
The household that overbought NBN 1000 on HFC
A couple on a heavily loaded HFC segment buys the Ultrafast tier expecting gigabit. On a busy street the shared peak speed lands well short of the ceiling, so they pay top-tier money for an evening result a boosted Fast plan would have matched. The street load, not the tier, set the limit.
The smart buyer who read the evening number
A work-from-home household ignores the "old cable" label, checks the Typical Evening Speed, picks a boosted Fast HFC plan from a retailer that buys plenty of bandwidth, and lands a steady 450 to 500 Mbps at 8pm for Fast-tier money. They got near-fibre value because they judged HFC on the right metric.
The insider insight
HFC is the connection most people underrate by a mile
Here is the part the "upgrade to fibre" crowd never says. The thing that made HFC look dated, the old coaxial cable, was never the bottleneck people assumed. The fibre behind it always had headroom, and the 2025 upgrade simply released it, lifting most HFC lines to the same top tiers as Fibre to the Premises. Meanwhile Fibre to the Node, the connection people often rate above HFC because it sounds more like fibre, got no boost at all and stays capped by its copper tail. The real ranking for most homes flipped: HFC now sits second only to FTTP, and comfortably above FTTN.
The non-obvious truth: where you can get HFC, it is quietly one of the best-value connections in Australia. You get fibre-class top tiers for the same price as before the boost, and the only real catch, the shared street segment, costs you a little speed at peak and nothing the rest of the day. Households that judge HFC by its Typical Evening Speed rather than its 1990s cable get near-fibre performance without paying for, or waiting on, a fibre upgrade they may not need.
The practical consequence: do not pay to escape HFC on reputation alone. Check the boost, check the evening number, and most of the time you will find you already have one of the better lines on the network.
Grounded in the analysis
What you should actually do if you have HFC
Specific moves that follow from how HFC sharing and the 2025 upgrade work, not generic advice.
Check whether the boost applies to your line
Most HFC lines are eligible for the late-2025 speed upgrade, but not all, and your retailer has to pass it on. Confirm it before you assume your Fast plan reaches 500 Mbps. Use the explainer above to see what the boost is worth on your street.
Size the tier to your street, not the headline
On a lightly loaded HFC street the top tiers shine; on a heavily loaded one the shared peak speed lands below the ceiling, so a boosted Fast plan often matches Ultrafast at 8pm for less. Buy the tier your evening reality supports, not the biggest number.
Choose the retailer by evening speed
HFC has two sharing layers, so the Typical Evening Speed matters even more than usual. Compare it across retailers on your chosen tier and lean on the ACCC Measuring Broadband Australia results. Most plans are month to month, so switch freely if the evening speed disappoints.

The bottom line
Why HFC deserves a second look in 2026
HFC reuses cable that was laid for pay-TV in the 1990s, and it shares the final street segment among neighbouring homes, so its honest weakness is a peak-hour dip when the whole street is online. That is real, and it is why the Typical Evening Speed matters even more on HFC than on dedicated fibre. But the reputation has not kept up with the reality. The fibre backbone always had headroom, the late-2025 NBN Co upgrade released it, and most HFC lines now reach the same top tiers as Fibre to the Premises while Fibre to the Node copper got nothing. So before you pay to escape HFC, check the boost, read the evening number, and judge it on what it actually delivers at 8pm. Do that, and you will usually find HFC is not the connection to flee, it is one of the best-value lines you can have.
Common questions
A Selectra expert answers your HFC questions
HFC stands for Hybrid Fibre Coaxial. It is one of the connection types that make up the NBN, and it works by running fibre most of the way to your neighbourhood, then using the existing coaxial pay-TV cable laid down the street in the 1990s to carry the connection the last stretch into your home. You will have the usual NBN gear: a utility box outside, an NBN connection box inside, and your own modem or router. The defining feature of HFC is that the final coaxial segment is shared among the homes on it, so capacity is pooled across a street rather than dedicated to one premises the way pure fibre is.
HFC is genuinely good, and the "old cable" worry is mostly outdated. After the late-2025 NBN Co upgrade, most HFC lines now reach the same top wholesale tiers as Fibre to the Premises, with the Fast tier pushed toward 500 Mbps and Superfast toward 750 Mbps at no extra wholesale cost. That puts HFC far ahead of Fibre to the Node copper and close to FTTP for everyday use. The one honest caveat is that HFC is a shared medium, so a heavily loaded street can dent speeds during the 7pm to 11pm peak. For the vast majority of homes that gap is small, and HFC is one of the best-value connections you can have.
Because HFC shares the coaxial segment on your street, and capacity is pooled across the homes on it. During the day, few of those homes are using much, so you can sit near the tier ceiling. From 7pm to 11pm, when the whole street streams, games and video-calls at once, that shared capacity is split more ways and your speed can dip. This is different from your retailer's shared bandwidth choice, which affects every connection type. With HFC there are two layers of sharing: the physical street segment and the retailer's bandwidth buy. The Typical Evening Speed already reflects both, which is why it is the honest number to compare.
Yes. From late 2025, NBN Co lifted the wholesale speeds on eligible Fibre to the Premises and most Hybrid Fibre Coaxial lines at no extra wholesale charge: the Fast tier moved toward 500 Mbps, Superfast toward 750 Mbps, and Ultrafast toward 2000 Mbps. HFC was included precisely because the fibre backbone behind it can carry the extra speed. The catch is that your HFC segment has to support it and your retailer has to pass it on, so confirm with the retailer before assuming the boost. Crucially, Fibre to the Node copper got none of this, which is why HFC has pulled clearly ahead of FTTN.
HFC sits between the two and, for most homes, much closer to FTTP. Fibre to the Premises is the gold standard: a dedicated fibre line all the way in, with no street sharing and the most consistent peak speeds. HFC reaches the same top tiers after the 2025 upgrade but shares the final segment, so a busy street can shave a little off the evening peak. Fibre to the Node is the weakest of the three because its final copper run physically caps many lines at NBN 50 or NBN 100 and it received no 2025 boost. So the order for most users is FTTP first, HFC a close second, and FTTN a clear third.
In almost all cases, yes. The physical HFC connection at your address stays exactly the same; switching retailers just changes who bills you and how much shared bandwidth is bought on your behalf. Most NBN plans are now month to month with no lock-in, so if your HFC line congests in the evening you can move to a retailer with a higher Typical Evening Speed without any new cabling or technician visit. The main thing to check is whether you keep your existing modem or need one from the new retailer, since some HFC setups are particular about the modem.
