Why Your NBN Bill Went Up, and How to Pay Less for the Same Speed

The bill went up and it is not a scam

Your internet bill went up in the second half of the year, and it was not the provider inventing a reason. It was a wholesale price increase that the retailers passed through, it took effect on 1 July, and it happens annually. Annoying, yes. A conspiracy, no. And outrage is not a plan, so here is what actually happened, followed by the part that pays for the article: how to spend less for the speed your house actually uses.

One more thing before the mechanics, because it saves an argument. The increase is legal, it was disclosed, and it sits inside the rules of the market; the announcement went out months before the bill moved, as the statement date shows. None of that makes it welcome. All of it means the only useful question is the one this article answers, which is what to do about it rather than who to blame.

What actually changed

The National Broadband Network is wholesale infrastructure. Retailers buy access from nbn and sell it to you, which means there are two sets of prices in the chain: the wholesale price nbn charges the retailer, and the retail price the retailer charges you.

The wholesale side is adjusted annually, tied to the consumer price index, and the July 2026 adjustment averaged 3.63 per cent. That figure comes from nbn’s own Wholesale Price Changes statement, published on 1 May 2026. What each retailer does with it is the retailer’s decision; some pass on the whole adjustment, some absorb part of it, and the differences show up in which tiers move and by how much.

Two mechanisms deserve naming, because they explain how an average can be true and still describe almost nobody. The first is that 3.63 per cent is an average across the wholesale catalogue, so some access arrangements rose by more and some by less; the figure is a summary, not a rate applied evenly to every connection in the country. The second is the retailer’s margin of discretion. A provider that wants to protect its budget customers can absorb part of the increase and recover it elsewhere, while a provider chasing margin can pass through more than its share. The same wholesale change produces different retail outcomes, and the table below is what that looks like in practice.

Who got hit hardest, and why that is odd

Here is the pattern from the providers’ own notices, each with its effective period. The figures describe the July 2026 adjustment, not what any particular reader pays; the reader’s own bill is the authority on that.

Canstar’s coverage of the round put the worst of it at up to $120 a year across providers, for readers who want the annual figure rather than the monthly one.

Now the odd part, and the reason this article is worth reading rather than skimming. The increases landed on the cheapest speed tiers, and the fast tiers were largely held. That is the opposite of the usual pattern, where premium products drift up and the budget end stays still. The reason is straightforward once you see it: the entry tiers are where the volume is and where competition thins out. The cheapest plans stopped being the safe harbour they used to be, which changes the arithmetic for anyone sitting on NBN 25 or NBN 50.

What that means depends on which side of the tier list you sit. On the entry tiers, this round took a larger share of your bill than of anyone else’s, and staying put is worth less this year than it was last year. On a fast tier, you were held, which is pleasant and temporary; nothing about the structure suggests the holding pattern repeats. Either way the response is the same, and it is not a protest. It is a decision made at the contract date rather than by default.

Does your speed tier actually fit your house?

The genuinely useful question, and the one nobody asks before choosing a tier. Speed tiers describe capacity, and capacity only matters if the house uses it.

In plain terms: NBN 25 handles browsing, email, music and one or two video streams, and it is fine for a small household that mostly watches one thing at a time. NBN 50 covers a couple of streams plus a video call, which is two or three people living ordinary online lives. NBN 100 is where busy households live: several streams at once, a video call running while someone games, big downloads that finish while everyone else keeps working. The faster tiers exist for the genuinely heavy setups, multiple 4K streams, constant large transfers, a household where the internet is the job. The site’s guide to the gadgets that make a home office work covers the other half of that point: when the house is also the office, the connection carries the meetings.

Most of the gap between the tiers is unused by most households, and the common pattern is paying for capacity the house never calls on. Two ways to check yours. Count the devices that stream at the same time in the evening, and add one for the video call that happens while they do. Then check what your address can actually achieve: the connection type differs street by street, between fibre, hybrid fibre coaxial and fibre to the node, and an address-level check with nbn shows which one you have and what it can realistically deliver. There is no point paying for a tier the line cannot reach.

Two refinements on the count. The first is the difference between a speed and a feeling: what people notice is not the headline number but consistency, and a smaller plan that delivers steadily can beat a bigger number that jitters at eight in the evening. When comparing, ask not just what the tier promises but how the provider performs when the street is busy; the published measurement programs exist precisely because the two are not always the same. The second is the upload side. Video calls, backups and file transfers run on upload, and a household that works from home feels a thin upload long before it feels a thick download. Check both numbers on your plan, not just the one in the advert.

The address check itself takes a minute. The wholesale network publishes an address-level lookup, and most retailers quietly run the same check as part of their sign-up flow. Enter the address, read the connection type it reports, and read the maximum speed the line supports for that type; that ceiling is the honest limit of everything on the shelf. A plan that promises more than the line can deliver is a plan that will disappoint at roughly the same time every evening, which is to say when the street is home and watching.

What is on your bill, and what to check

Five things, checked once, in the time it takes to drink a coffee.

The tier you are on. The price you are paying, which may not be the price on the provider’s current page. Whether an introductory discount has ended, because that is the one that catches most people: the first-year price quietly becomes the standard price, and the increase feels mysterious even though the paperwork said it was coming. Whether a modem is being paid off in instalments, since that line eventually falls away and the bill should follow it down. And the contract end date, because that is the day you become free to move, and most people discover it months late.

One distinction worth making while the bill is open, since both products get called internet: a home connection and web hosting are different services with different meters. The site’s explainer on what you are actually paying a hosting provider for covers the website version of the question.

The whole check is a ten-minute job with a phone in one hand. Photograph the bill, note the four numbers that matter, and keep the photograph somewhere you will find it in twelve months, because the trap this section describes is a slow one: nothing breaks, nothing alerts you, and the price simply stops being the price you agreed to.

Switching is usually free and usually takes minutes

The other half of the community’s advice is sound, and it is worth stating plainly. Most providers do not charge an exit fee on a no-contract plan, and the switch is handled between the two providers, which means the reader’s job is choosing and the rest happens behind the scenes. The habit that saves money is not switching constantly; it is checking what is available at the next recontract date instead of staying out of inertia. The introductory-price cycle rewards the reader who treats the anniversary as a decision point.

For a genuinely light user, there is a third option worth naming: a mobile broadband plan with tethering, which handles email, browsing and a modest amount of streaming without a fixed line at all. It is honest to say what it gives up: the data allowance is finite, speeds vary more with the network, and a house full of screens will find its ceiling quickly. For one person who mostly reads and occasionally streams, it can be the cheapest sensible answer.

What switching actually costs is worth stating honestly, because the savings talk usually skips it: an afternoon of arranging, a possible modem change if the old one is locked to the old provider, and occasionally a short gap while the new service activates. None of it is difficult, all of it is friction, and the friction is why people stay. Set it against a year of the difference, and the trade usually makes itself clear.

The free upgrade, and whether you qualify

Briefly, because it is a check rather than a section. nbn has been running a fibre upgrade program that moves eligible addresses on older connection types onto fibre, at no charge to the customer, when an order is placed through a retailer. Eligibility is address-specific, it changes as the program rolls out, and nbn is the authority for whether a particular house qualifies. Check the address before getting attached to the idea, and do not take a street-level rumour as a ruling.

One note for renters and people in shared housing: the check belongs to the address, not the tenant, so it is worth doing before a lease decision and worth passing on when you leave. The program moves street by street, and the quickest way to know is the address tool rather than the neighbour’s recollection.

Where to take it next

The increase was real, annual and largely aimed at the cheapest tiers, and the response is a short routine rather than a big decision. Read the bill once: the tier, the price, the discount expiry date and the contract end. Count what the house actually streams in the evening. Check the address’s connection type and its fibre upgrade status. Then, when the contract date comes around, compare what is on offer rather than renewing by default, because the introductory cycle was designed for the reader who renews without looking. The rises will come again next July. The habit is what makes them survivable.
