Best NBN 100 plan for October 2025

Speed, price, data, modem options and customer support all play a big part in picking the best NBN 100 plan for us.

This month's pick is from amaysim, which comes with unlimited data and no lock-in contract.

Get this plan for $40/mth for the first 2 months (ends 14.10.25). $80/mth for the next 4 months, then $90/mth. Eligibility criteria, T&Cs apply.

If you have Fibre to the Premises (FTTP) or Hybrid Fibre Coaxial (HFC) connection, you will be automatically moved to amaysim's NBN 500 plan. It costs the same and is 5 times faster (more on this in just a bit).

Read about how we chose the best NBN 100 in our guide, where we also round up top picks across other speed categories.

Note: We only looked at Finder partners to pick the best NBN 100 plan.

Is NBN 100 fast enough?

NBN 100 plans come with download speeds of up to 100Mbps and upload speeds of either 20Mbps or 40Mbps.

The difference in upload speeds depends on whether you choose NBN 100/20 or NBN 100/40, the latter being slightly more expensive by around $5 to $10 a month.

NBN 100 is great for larger families where 4+ people are actively online, even simultaneously - or heavy internet users.

According to Finder's Consumer Sentiment Tracker, 81% of Aussies say they're satisfied with their speeds on NBN 100.

Pros

  • Well-suited to a household of 4+ people or heavy internet users
  • Download and upload speeds are good for streaming, gaming and working from home
  • You can stream in high-definition or 4K without buffering interruptions
  • Heaps of sign-up deals available, including 6-month discounts

Cons

  • Some NBN connections may not be able to achieve the full 100Mbps speeds
  • A lower-speed plan might be sufficient and cost-effective for families who aren't all online or using the internet heavily at the same time

Keep in mind that not all NBN plans on the same tier are equal. Look out for the advertised typical evening speeds on the plan. You want to aim for anything close to the maximum speed available on the tier (100Mbps), to really get your money's worth.

Did you know?

NBN has boosted speeds on NBN 100 plans at no extra cost, making them up to 5 times faster. This effectively creates a new NBN 500 speed tier. Most providers in our database now offer NBN 500 plans for the same price as the old NBN 100. The main catch? You'll need a Fibre to the Premises (FTTP) or Hybrid Fibre Coaxial (HFC) connection to access these faster speeds. The easiest way to see if you can get NBN 500 at your address is to enter it on a provider's website - they'll only show the plans available at your location. Read about all the NBN speed upgrades in detail to see what else has change.

How much do NBN 100 plans cost?

The average monthly cost of fixed-line NBN 100 plans on Finder is $98 a month as of October 2025.

However, there are plenty of sign-up deals that can bring the monthly price down to under $70 a month for the first 6 months.

Some providers also offer ongoing prices for as low as $85 a month - you just need to shop around to snag a good price.

Can I get NBN 100?

Every NBN connection type can support NBN 100, but not all will reach the maximum speeds available on this tier.

Before signing up with a provider, ask them to double-check your connection type and see if it's worth getting NBN 100.

You don't want to overpay for speeds your connection can't actually achieve.

Did you know?

NBN Co is running a free fibre upgrade programme. Over 10 million homes and businesses currently on fibre-to-the-node (FTTN) or fibre-to-the-curb (FTTC) will be upgraded to FTTP by the end of 2025. To trigger the upgrade, you'll need to sign up for an NBN 100 plan or faster. Head to NBN Co's website, enter your address, and see if you're eligible for the upgrade.

Is it worth getting NBN 100?

It's worth it if you've got multiple users at home, love streaming in 4K, or work from home and need fast upload and download speeds.

But if you're a light or moderate user or on a budget, a lower-speed plan might be enough.

The great thing is switching between speed tiers is easy as - try NBN 50 first, and if you end up experiencing buffering internet, you can switch to NBN 100.

Tim Bennett's headshot
Is NBN 100 fast enough?

"I love fast internet. I send and receive a lot of really big files, as well as doing my fair share of streaming and online gaming. But even with all that, an NBN 100 plan suits me fine. I was in a share house with 4 similar people, including a video editor and a graphic designer who worked from home. Our 100Mbps connection was great, and it was always more than enough."
