NBN 100 FAQ

A leading choice climbing through the best NBN plans ranks to become Australia's favourite speed tier is the home 'fast' plan — otherwise known as NBN 100. According to the latest ACCC data, the best NBN 100 plans are evolving as the first pick among new connections, with many customers upgrading from the extremely popular NBN 50 tier.

Right now, 100Mbps download speeds are theoretically the highest achievable by all NBN connection types, including fibre-to-the-node (FTTN) connections. The best NBN providers in Australia offer 100Mbps plans, and for those that don't deliver max speeds, the average peak-time speed still comes close to 100Mbps — like Mate's 97Mbps cap — so you'll likely not notice any difference.

While NBN 100 plans may not offer the fastest speeds across the fixed-line network, 100Mbps would easily cover an average household of four or more users with multiple devices during the busy evening hours.

Our research shows the average price of the tier is currently AU$93.26p/m. However, several ISPs offer attractive introductory discounts, which could see you spend as little as AU$60p/m for a 'fast' plan.

With lingering discounts and price cuts, there's never been a better time to switch your NBN providers to maximise your savings. Scroll on to find our picks of the best NBN 100 plans available right now.

Mate | AU$60p/m using code FUTURE30 (for 6 months, then AU$90p/m)

Mate's NBN 100 plan is one of the cheapest offerings around, providing 97Mbps speeds during the typical evening hours. This plan is great for working from home, 4K streaming or gaming, and comes complete with unlimited data.

Using our exclusive code FUTURE30, you'll save AU$180 during the first six months with Mate. You'll even get a free subscription to sports streamer, Bein Sports, typically retailing at AU$14.99p/m. Plus, if you want to bundle a phone line, you can add a home voice plan and score an extra AU$10 off discount! What a win.

Total minimum cost: AU$60 | Total cost for first year: AU$900 | Yearly cost after discount: AU$1,080

Amaysim | AU$70p/m (for 6 months, then AU$90p/m)

Don't be fooled by this slightly more expensive introductory outlay — Amaysim's 100Mbps plan is a favourable midrange option, as it's still cheaper than the average of AU$93p/m for the tier.

Amaysim's offer costs the same as Mate's plan above in the long run, but you could pay as little as AU$80 per month if you bundle a mobile plan with your NBN. In other words, that could reduce your ongoing bill by a massive AU$120 if you sign up for a phone line.

Do note, though, Amaysim only offers NBN services, so you'll need to supply your own modem for this plan.

Total minimum cost: AU$70 | Total cost for first year: AU$960 | Yearly cost after discount: AU$1,080

Cheapest NBN 100 plan

SpinTel | AU$68p/m (for 6 months, then AU$86.95p/m)

SpinTel features again in our NBN 100 category, as it offers sensational value for a low cost. Across all NBN 100 plans, the offering has the lowest first yearly price of a modest AU$929.70 and one of the cheapest ongoing costs after the introductory discount ends.

There’s little in the way of extra features with this plan – which will likely go some way to explaining the low cost – but if you’re just searching for a no-frills NBN plan to get you connected, Spintel is well worth your attention.

Total minimum cost: AU$68 | Total first year cost: AU$929.70 | Yearly cost after discount: AU$1,043.40

Flip | AU$69p/m (for 4 months, then AU$83.90p/m)

It's been a while since we've highlighted this plan from Flip in our best NBN 100 lineup, because, quite frankly, their introductory offers weren't cutting it. However, Flip has quite literally flipped the script, and is now offering a competitive four-month AU$69p/m outlay.

Do note, though, Flip's ongoing rate is a touch more expensive, so do keep that in mind after the discount ends.

Total minimum cost: AU$69 | Total cost for first year: AU$947.20 | Yearly cost after discount: AU$1,006.80

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.

Some NBN providers offer 100/40 plans as an option, however, you will need to pay around AU$10p/m extra.

Best overall NBN 100/40 plans

Mate | AU$70p/m using code FUTURE30 (for 6 months, then AU$100p/m)

Mate's NBN 100/40 tops out at the cheapest plan in the first year, especially compared to other budget providers. Do note, though, the ongoing price is more expensive than most across the tier. Much like its 100/20 plan, Mate advertises 97Mbps downloads and 36Mbps uploads during the busy evening hours.

This plan is great for uploading large files, 4K streaming or gaming, and comes complete with unlimited data.

Total minimum cost: AU$70 | Total cost for first year: AU$1,020 | Yearly cost after discount: AU$1,200

Tangerine | AU$77.90p/m (for 6 months, AU$92.90p/m)

Tangerine has the cheapest 100/40 plan currently available, particularly after the introductory offer ends. With 34Mbps uploads, this plan doesn't quite reach theoretical maximum speeds, but it's unlikely to have much of a real-world difference.

Much like the 100/20 plan, you can expect to achieve the full 100Mbps download speeds during the busy evening hours.

Total minimum cost: AU$77.90 | Total cost for first year: AU$1,024.80 | Yearly cost after discount: AU$1,114.80

Best NBN 100 plans: Major NBN providers

If you’re looking to upgrade to an NBN 100 plan or switch providers, it makes sense to check out deals that are being offered by Australia’s major NBN providers: Telstra, Optus and TPG. In most cases, an NBN plan from any of the big 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 bundle up 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.

Best Optus NBN 100 plan

Optus | AU$99p/m (for 6 months then AU$99p/m)

According to ACCC data, Optus delivers 100.6% of advertised download speeds across all hours of the day — meaning you can reasonably expect to reach 100Mbps during the peak evening hours of 7-11pm.

The only thing to note though, is that this plan's minimum cost is AU$405, as it includes the modem. However, you won't pay any additional fees for the modem if you remain connected for 36 months or more.

Minimum monthly cost: AU$405 (including modem fee) | Total yearly cost: AU$1,188

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 your 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 100Mbps, delivering, on average, 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, we would recommend NBN 100.

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 households.

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, and check the T&C's 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.
