Best NBN 100 plans

NBN 100 is the most popular form of fixed-line internet in Australia and it's easy to see why. The asking price is a lot more approachable than the likes of NBN 250 and NBN 1000, but the performance is still  fast enough for the average household. 

So which NBN 100 plans are the best? The answer depends on your needs, but we've saved you some trouble with this round-up of the NBN 100 plans from various providers, comparing your options by value, price and performance.

Our pick this month for the best NBN 100 plan in Australia comes from SpinTel. Priced at a competitive $86.95 per month (plus a $16.95/mth discount for the first six months), the SpinTel NBN Unlimited Plan offers 100Mbps in self-reported typical evening download speeds and 18Mbps in upload speeds.

While self-reported speeds are usually a good indicator, it's worth noting SpinTel isn't included in the the ACCC's performance reports, which is a third-party program that records real-world speeds of most of the major providers.

Still, for $70 per month for the first six months and $86.95 per month thereafter, that's worth taking a punt on. After all, SpinTel has no lock-in contracts, so it's a low-risk trial and you can swap to another provider before the deal is done if you want to grab another intro discount from elsewhere.

We track the prices and typical evening speeds attached to NBN 100 plans from among the over 30 internet providers in our database. When it comes time to make our monthly pick for the best NBN 100 plans, we favour plans with the lowest price, unlimited data, no contract, and a minimum of 100Mbps for typical evening download speeds. NBN 100/40 plans don't tend to take top spot in this ranking, but we've given them their own section below.

Our comparison of the best 100Mbps NBN plans also highlights introductory deals because changing providers regularly is the surest way to save money on your monthly NBN bill, thanks to a lack of contracts and the prevalence of intro discounts.

It's worth nothing the cost of plans tend to change every July, which can make longer term predictions less reliable. Even so, we still include annual pricing in our comparisons because hopping between providers a couple of times per year isn't everyone's cup of tea.

Usually, the main things you lose by signing up to a cheap NBN 100 plan over a more-expensive one are extra perks or a robust customer support service. The speed performance difference between a cheap and premium NBN 100 plan usually comes down to upload speeds, though even here it's a matter of 3Mbps at most for the standard NBN 100/20 plans. And if uploads are important enough that 3Mbps matters to you, consider paying a bit more for an NBN 100/40 plan with double the max uploads.

As for pricing, most NBN 100 providers will offer your first handful of months at a discount before bumping you up to the regular price. If you stick with the same provider for too long, you might end up paying for it. But contracts are few and far between, so you can change often to keep the savings rolling in. 

Lastly, it's good to investigate what kind of bundles, discounts and NBN modems each provider offers. Some NBN providers offer strictly BYO (Bring-Your-Own) modem plans, while others supply one for a once-off fee. But a select few will allow you to bundle a modem (or mobile phone) with your NBN plan, allowing you to pay your hardware costs over a set period of time. 

The cheapest NBN 100 plan in our database right now is the Mate No Worries nbn 100/20 plan. It offers 97Mbps in self-reported typical evening download speeds and 17Mbps in upload speeds. Now, 97Mbps isn't the 100Mbps of some other plans' reported speeds, but 3Mbps isn't a huge gap.

New customers can also save $30 per month for the first six months if they sign up before the end of May 2025 and use the code MATE30 at checkout. That discount knocks the intro price down to $60 per month.

While jumping between intro discounts will save you money, that might not be what you're after. If you're keen to set, forget and save some money, opting for an NBN 100 plan with cheaper standard pricing might make more sense than one with intro discounts that expire after a few months. Below, we've compared plans based on their total cost over the first 12 months after signing up.

Southern Phone currently has the cheapest NBN 100 plan in our database over the first 12 months after signing up, and its ongoing yearly price is also quite low.

New customers get $24 off for the first twelve months, after which the ongoing price is $89.95. The telco also reports good typical evening speeds – 100Mbps downloads and 19Mbps up, the latter of which is only 1Mbps below the maximum for this plan. There's also no contract or set up fee, so you can easily change providers if it doesn't end up being for you.

Those who work from home, make regular use of cloud storage, use video conferencing, or spend a lot of time playing games online may chafe on the 20Mbps upload speeds offered by regular NBN 100 plans. Fortunately, a select few providers offer a version of NBN 100 with faster upload speeds of up to 40Mbps upload speeds, called NBN 100/40 plans.

Exetel is one of those providers and its Power Home NBN plan reports typical evening download speeds of 100Mbps and 34Mbps upload speeds (plus low latency, according the ACCC's speed test results). Some of these uses also benefit from having low latency, so we've included that when considering our current NBN 100/40 pick.

Exetel might be our favorite for now, but it's hardly the only game in town. Check out the widget below for a shortlist of NBN 100 providers that offer a 40Mbps upload speeds as an option, ordered by their popularity with our visitors over the last seven days.
