Average NBN plan costs compared: what’s a fair price for your speed tier?

When we recommend the NBN plans here at TechRadar, a major component in our decision making is how much a plan costs. Of course, the cheapest option isn’t necessarily going to be the outright best one, but ultimately we make it our mission to track down which NBN plans offer the right mix of price, speed and features that then results in the greatest overall value.

One of the clearest indicators as to the value of the best NBN plans is where they sit in comparison to the average monthly cost for their speed tier. We maintain an internal database of NBN plan prices from around 23 major providers, and we’ve been tracking them for so long that, generally speaking, we can immediately spot changes as soon as they’re made. From these prices, we can easily calculate the average price for a specific NBN plan tier as needed.

If you’ve been looking at your internet bill lately and wondered if you’re paying too much, there’s a good chance you are. To help you figure that out, we’ve collated the current average monthly prices for each NBN speed tier in the table below.

If you find you are paying more than the average and are looking to switch to a better-value provider, we’ve also included a selection of plan comparison tables below (one for each speed tier) with prices that fall below the current average.

A greater-value internet plan could await!

As you can see from the table above, there’s comparatively little difference in price between NBN 50 and NBN 100 plans, and going further, little difference between NBN 50 and the newly introduced NBN 500 tier.

If you’re currently stuck on a 50Mbps NBN plan because your home has an older NBN connection technology, you may be eligible for the free fibre upgrade – if so, we unequivocally recommend you take up the opportunity, and the faster speeds it’ll unlock.

Compared to an NBN 50 plan, the new NBN 500 tier will give you up to 10x faster download speeds for approximately AU$6 more each month on average.

Are you paying too much?

Comparing your current NBN bill against the average prices listed above is a quick and easy way to determine if you’re paying too much for your plan (or if you’ve got yourself a cracking deal, of course). If you are paying too much, the good news is that there are plenty of excellent plans available for less than the monthly average – below are the top five cheapest plans in our database from each speed tier.

NBN plan price FAQ

How much should I pay for broadband in Australai?

You should only pay for the internet speeds that you’re actually going to use. You can consider the number of devices you need to connect to the internet and whether your household engages in any particularly demanding activities such as gaming, 4K streaming and so on. There’s no point paying for a 2,000Mbps NBN plan if you only need to surf the web and carry out other basic tasks. The AU$90 average price for an NBN 50 plan is fair, but you can pay a lot less if you shop around.

What is the cheapest internet plan?

The cheapest internet plan of those we monitor is Flip’s NBN 25 plan. It starts at just AU$39 per month for the first 4 months, before increasing to a regular ongoing cost of AU$59.90 per month.

What internet speed do I need?

The best internet speed for your household will depend on the number of people living there, the number of devices that need internet access – this includes smart home technology such as lightbulbs and switches – and what you need the internet for. If you want to watch Ultra HD 4K movies or TV in multiple rooms at once, while also gaming and participating in video calls, you’ll need a fast NBN plan such as NBN 500. The good news is that faster plans have become more affordable since September 2025.

How do I get a fast NBN plan?

If you want to sign up for an NBN 500 or faster plan, then you’ll first need to make sure you have the required connection type at home – these are fibre-to-the-premises (FTTP) and hybrid fibre-coaxial (HFC). If you don’t, you may be eligible for NBN Co’s free fibre upgrade to have FTTP technology installed at your home, after which will grant you access to faster speed tiers.

Do note, that in order to receive the free fibre upgrade, you will need to place an order for at least an NBN 500 plan. Previously, customers had to order an NBN 100 plan, but since the speed upgrades have arrived, the requirement is now a 500Mbps plan.
