The best NBN 100 plans may not offer the outright fastest speeds on the National Broadband Network, but it is the fastest (theoretically) achievable by all NBN connection types. So, if you live in a household with multiple people wanting to get online to stream and download content throughout the day, an NBN 100 plan could be the perfect option.
Fortunately, the majority of NBN providers in Australia offer NBN 100 plans, and many promise to deliver the full 100Mbps download speed you’re after. For those that don’t, their typical evening speed still comes close enough that you’re unlikely to notice a difference.
This means choosing the best NBN 100 plan will likely come down to price, any extras included with the plan, or whether a certain NBN provider services your address. We’ve therefore partnered with WhistleOut to compare NBN 100 plans from more than 30 providers to bring you the best plans currently available.

Best NBN 100/40 plans
We've already made a passing mention to NBN 100/40 plans, and if it sounds like the plan for you, you'll want to know which ones are the best. NBN 100/40 used to be the default for most NBN 100 plans, but telcos began the downgrade to 20Mbps uploads instead of 40Mbps a few years ago.
Some NBN providers still offer 100/40 plans as an option, however, you will just need to pay around AU$10p/m extra.

Best NBN 100 plans: Major NBN providers
If you’re looking to upgrade to an NBN 100 plan or switch your provider, it makes sense to check out what deals are being offered by Australia’s major NBN providers: Telstra, Optus and TPG. In most cases an NBN plan from any of these three won’t be the cheapest option, but you are at least highly likely to experience a reliable service. And, since all three provide mobile services too, you may be able to create a bundle and save some money. Other perks, such as free subscriptions to streaming services, may also be included.
All three also provide 4G backup with their modems, so if your fixed-line NBN connection drops out, you’ll still be able to connect to the internet via 4G data.

NBN 100 FAQ
What is NBN 100?
NBN 100 is a speed tier that can offer download speeds up to 100Mbps, although the actual speed you can achieve will vary depending on network conditions and NBN connection type.
However, a good proportion of NBN providers in Australia do now claim to offer the full 100Mbps typical evening speed. Some may still fall slightly short of this, delivering between 90 - 99Mbps typical evening speeds instead.
Is it worth getting NBN 100?
If you live in a household with multiple users wanting to use the internet at the same time, and if you stream and download video content in 4K resolution or large files, then yes, NBN 100 is worth it.
In fact, while you can get even faster NBN plans in the form of NBN 250 and NBN 1000, NBN 100 will likely be more than fast enough for most Australian homes.
How do I get NBN 100?
All NBN connection types are theoretically capable of supporting 100Mbps download speeds, however you may find in a real-world scenario that this isn't actually the case.
If you have a hybrid fibre coaxial (HFC) or fibre-to-the-premises (FTTP) connection type, then you should definitely be able to achieve 100Mbps downloads. If you have any other NBN connection type, then it isn't guaranteed.
Some NBN providers offer free trials of their services, so be sure to take advantage of these before signing up.
What does NBN 100/20 mean?
NBN 100/20 refers to the download and upload speed of your plan, i.e. 100Mbps download and 20Mbps upload. 20Mbps upload speeds should be more than enough for most households, but if you need to conduct multiple video calls or you spends hours online gaming, then you may need something faster.
In these instances, an NBN 100/40 plan is available, with 100Mbps download speeds and up to 40Mbps upload speeds.
