What is NBN 100?

NBN 100 is one of the six NBN speed tiers in Australia. In short, on an NBN 100 plan, you can expect a maximum download speed of 100Mbps, which is one of the faster speeds currently available.

  • NBN 100: also written as 100/40 or 100/20, it offers 100Mbps download speeds and 20 or 40Mbps upload speeds. It is also known as the Fast NBN speed tier.

NBN 100 plans are listed as having a choice of two upload speeds because they can be sold with one or the other, in separate plans, although both keep the 100Mbps maximum download speed.

  • Keep in mind: upload speeds don't come with an equivalent of a "typical evening speed", which means the provider isn't required to specify what upload speed you'll get on your plan. Instead, your plan will go off the maximum upload speed available. For 100/40, that means you can expect a maximum of 40Mbps. For 100/20, that's a maximum of 20Mbps.

NBN 100/40 plans

These are plans with a higher maximum upload speed, with an average price in the Finder database of roughly $95 a month. Upload speeds can be important for you depending on what you're looking to use your Internet connection for. Those who work from home may find they need a higher upload speed depending on what's needed for their job.

  • Useful for: sharing large work files with clients, high-quality live video streams, multiple video conferences going on at the same time in your household.

NBN 100/20 plans

These plans come with half the maximum upload speed of 100/40 plans. The lower upload speed leads to a lower average price, which is about $85 a month as calculated with plans in the Finder database.

  • Best for: those who don't have high upload requirements.

Is it worth getting NBN 100?

NBN 100 is best for people who meet one or more of the following criteria:

  • Are part of a large household (four or more users)
  • Have more than two people working from home at once
  • Hate having to wait for large files to download
  • Run a small business with several employees

NBN 100 plans cost around $70–$100 a month, depending on what plan features you're after. Typically, you can expect to pay more on plans with higher typical evening speeds.

In addition to choosing between 100/20 and 100/40 depending on your upload needs, it's worth considering if a lower typical evening speed would be better suited to you. NBN 50 plans are in the speed category just under NBN 100.

If NBN 100 plans seem a bit too fast for your needs, an NBN 50 plan might be a better option. NBN 50 plans:

  • Can still be used for working from home, downloading files and streaming
  • Are suitable for households with two or three people, possibly even four depending on how often everyone is online at the same time
  • Could save you an average of $265 a year on your Internet bill

With most NBN plans being contract-free these days, if you're doubting the need for NBN 100 speeds, you could easily sign up for an NBN 50 plan first then upgrade to an NBN 100 plan if you find you need faster Internet.

What is the best NBN 100 plan?

We can help you decide what makes the best NBN 100 plan for your needs, but there is no singular best plan for everyone. While price is a big factor for some people, the cheapest plan isn't always going to be considered the best one to others.

We think the best NBN 100 plans come with the following:

  • Typical evening speeds over 80Mbps are an indication of a good NBN 100 plan. The ACCC suggests that Fast plans should be above 60Mbps but most plans should be giving you at least 80Mbps. If the plan you're looking for comes with slower speeds but a hefty price tag, you can probably do better by comparing more plans.
  • Unlimited data is the norm these days. While data-capped plans do exist (e.g. 500GB a month), these plans aren't usually the best value. For example, Aussie Broadband sells a 500GB NBN 100/20 plan for $85, but for just $4 more a month, you could get unlimited data and never have to worry about running out.
  • Month-to-month contracts are usually the default on NBN plans which makes it easy for you to switch plans if you're unhappy with what you're getting.
  • No set-up fees are a common plan feature and mean you don't have to pay any extra fees when you sign up for a new plan.
  • The option to BYO modem is also handy if you already own a modem from your previous provider. Most modems are compatible with other providers but you should always check with your new provider whether the modem you currently have will work with your new plan.

Although there is no overall best NBN provider for everyone, here's an overview of five popular providers, including some that have been popular with our Finder users.

Telstra logo


Telstra's NBN 100 plan costs $100 a month ($110 after the first 6 months). It comes with 100Mbps typical evening speed and up to 20Mbps upload speed.

When you sign up to Telstra's NBN 100 plan, you'll get the Telstra Smart Modem with 4G backup for free if you stay with Telstra for 24 months. Otherwise, if you leave before then, it'll cost you $9 for each remaining month out of the 24.

Telstra has a lot of bonus features as part of its NBN 100 plan, including access to Telstra Plus rewards, a home phone line included and more. It also boasts the highest typical evening speed of all the providers in our database.

TPG logo


TPG's NBN 100 plan costs $79.99 a month ($89.99 after the first 6 months). It comes with 85Mbps typical evening speed and up to 20Mbps upload speed.

You have the option of signing up for a month-to-month plan or a 6-month contract. Both will cost you the same amount each month, but the 6-month contract waives the $99.95 set-up fee that comes with the no-contract plan. So weigh up whether your freedom on a no-contract plan is worth paying the set-up fee.

TPG has become Australia's largest Internet provider following its merger with Vodafone-Hutchison. It provides decent speeds at an attractively low price for the first six months, but not much in the way of extras and no BYO modem options.

iiNet Logo


iiNet's NBN 100 plan costs $89.99 a month ($99.99 after the first 6 months). It comes with 85Mbps typical evening speed and up to 20Mbps upload speed.

You have the option to BYO modem with iiNet or purchase one from it for $99.95. If you sign up to a 6-month contract with iiNet, your modem cost is discounted by $40.

iiNet is wholly owned by TPG, but distinguishes itself with its own NBN 100 offering. The monthly cost is $10 higher than what TPG provides, but iiNet has Fetch TV entertainment options, whereas TPG does not.

Tangerine Logo


Tangerine's NBN 100 plan costs $74.90 a month ($89.90 after the first 6 months). It comes with 83Mbps typical evening speed and up to 20Mbps upload speed.

Tangerine gives you the option to BYO modem or you can purchase one from it for $129.90, which is actually quite expensive for a modem from a provider. You also have the choice of bundling a home phone line with your plan for an extra $10 a month.

Tangerine is heavily focused on value and all of its plans reflect that. The NBN 100 plan from Tangerine is the cheapest in our database for the first 6 months. It also offers a 14-day NBN trial which offers you a refund on plan fees if you're unhappy with your service. T&Cs apply.

How fast is NBN 100 speed?

NBN 100 promises maximum download speeds of 100Mbps and maximum upload speeds of 20 or 40Mbps, depending on your plan. These numbers are only maximums and your actual speed will more closely resemble your plan's typical evening speed.

Here's how NBN 100 compares to other tiers in terms of various downloading activities:

Downloading an album (100MB)16 seconds8 seconds3.2 seconds
Downloading a 2-hour HD movie off Netflix (5GB)14 minutes7 minutes2 minutes 48 seconds
Downloading a new video game (40GB)1 hour 47 minutes54 minutes21 minutes 36 seconds

Is NBN 100 the right speed for me?

If you're living with three or four other people who are all using the Internet at the same time to work, stream or video chat, you'll probably benefit from NBN 100 speeds.

If you don't think your household is that busy, consider an NBN 50 plan which can help you save on your Internet bill. If you're on a month-to-month plan, you'll be free to switch to an NBN 100 plan if you find that NBN 50 isn't enough for you.

Frequently asked questions

Can NBN go faster than 100 Mbps?

The NBN is capable of reaching faster speeds than 100 Mbps, depending on your connection technology. Two faster speed tiers exist, NBN 250 and NBN 1000, which are capable of delivering up to 1Gbps (10 times faster than NBN 100). These plans only really suit people with very high Internet downloading needs or small to medium businesses.

  • Note: an NBN 250 plan actually has slower upload speeds than NBN 100 (25Mbps vs up to 40Mbps), which should be taken into consideration for those who consider upload speeds to be important.
