The best NBN 100 plans should allow four or more people to use the internet at the same time, whether they’re streaming in 4K or downloading large files. While faster NBN 250 plans and NBN 1000 plans are also available, 100Mbps is perfect for families or small households with heavy internet usage.

Among the providers we monitor, the average typical download speed for an NBN 100 plan is currently 95Mbps. That means many providers are offering close to maximum download speeds of 100Mbps. As for price, the average cost is currently sitting at AU$92 a month, but a good range of NBN providers are offering deals below this price. You’ll find our top recommendations on this page.

Exetel | NBN 100 | Unlimited data | No lock-in contract | AU$68.99p/m (first 6 months, then AU$84.99p/m)

We recommend Exetel for the best NBN 100 plan overall. You’ll pay AU$68.99 a month for your first half-year on the service, and after that, its regular price is AU$84.95. That makes Exetel’s NBN 100 plan around AU$7 cheaper than the average monthly cost in this tier. We particularly like this plan because you can bump it up to NBN 250 speed using Exetel’s Speed Boost feature.

Total minimum cost: AU$68.99 | Total cost for first year: AU$923.88 | Yearly cost after discount: AU$1,019.88

Best fast NBN 100 plan


Exetel | NBN 100 | Unlimited data | No lock-in contract | AU$68.99p/m (first 6 months, then AU$84.99p/m)

Exetel’s NBN 100 plan comes with a maxed-out typical evening speed of 100Mbps, making it an easy choice for best fast NBN 100. Not only that, but the telco gives you five Speed Boost days each month to push your plan up to 250Mbps, and you can use them any time you want. Anything that’s unused rolls over into a bank which holds a maximum of 30. Throw in this plan’s discounted introductory cost, and it’s a clear winner.

Cheapest NBN 100 plan


Flip | NBN 100 | Unlimited data | No lock-in contract | AU$69p/m (first 6 months, then AU$79.90p/m)

Flip doesn’t have the cheapest intro cost among NBN 100 plans (that honour goes to Tangerine), but we’ve run the numbers and found that you’ll pay a lower cost for your first year with Flip than you would with Tangerine, and you’ll also pay a cheaper yearly cost after the discount ends. In our mind, this seals the deal. However, Flip’s typical evening speed is 91Mbps, which is a little below the average of 95Mbps in this speed tier.

Total minimum cost: AU$69 | Total cost for first year: AU$893.40 | Yearly cost after discount: AU$958.80


How fast is NBN 100?

NBN 100 plans offer download speeds up to 100Mbps, although actual usage will vary, particularly during the busy hours between 7pm and 11pm. Most NBN providers who offer a plan on this tier don’t report a typical evening speed of 100Mbps, with the average speed sitting at 95Mbps.

There are two types of NBN 100 plan, and what differs between them is their maximum upload speed. The more popular NBN 100/20 plan offers maximum uploads of 20Mbps, while the less common NBN 100/40 plan has a maximum upload speed of 40Mbps.

NBN providers don’t always disclose which of these two plans you’re signing up for, so check the provider’s critical information summary if you’re unsure. In the meantime, the ACCC is pushing for internet providers to be more transparent about upload speeds.

How much does NBN 100 cost?

The market has plenty of variety when it comes to cost for an NBN 100 plan. Prices range between AU$79 to AU$110 a month for an ongoing rate, but the average monthly price of an NBN 100/20 plan sits at AU$92 a month, while an NBN 100/40 plan will set you back AU$99 a month on average.

Plenty of telcos will also offer you a six-month discount when you first sign up to an NBN 100 plan, and these prices start around the AU$63 mark.

As you might expect, the telco with the most expensive NBN 100 plans is Telstra. You’ll typically find that Telstra sweetens the deal by offering other inclusions or discounts, such as a modem with 4G back up, and sometimes free subscriptions to Binge, Kayo and others for a limited time.

Can I get NBN 100?

While all connection types can sign up for an NBN 100 plan, not all of them may be capable of getting the full speeds offered by the service. Before signing up with a provider, it's worth double checking what connection type you have – such as hybrid fibre coaxial (HFC) cable or a fibre-to-the-node (FTTN) connection – and asking the telco if it’ll be suitable for the speed tier.

To check what NBN connection type you have, you only need to enter your address on the provider’s website, or check your address on NBN Co’s website. Some providers offer a trial period to test their service, so be sure to make use of this if it’s an option, and let them know if you’re unsatisfied with the speeds you’re receiving. We have a dedicated guide on how to do an NBN speed test if you need.

What providers have NBN 100?

Almost every provider offering an NBN service is offering the NBN 100 tier as its top-rung option, with only a select number of telcos offering the superfast NBN 250 plans and ultrafast NBN 1000 plans above it.

This means that Telstra, Optus, TPG, Aussie Broadband, Exetel, Spintel, Tangerine and plenty of others all have compelling NBN 100 plans to choose from.

NBN 50 vs NBN 100?

As with any purchasing decision, the 'better' option won’t be better for everyone. For light internet users – that’s households of two to four users that stream content and don’t plan to use it for anything more intensive – an NBN 50 plan is likely to be more than enough.

But for anyone currently running into congestion problems, or anyone that wants their download wait time drastically cut down, the extra AU$200 or so per year is certainly a small price to pay for double the download speeds – particularly in the context of a plan that already costs around AU$750 annually, in the case of NBN 50 plans.
