NBN Speed: What’s Good? Mbps, Download and Upload Speeds Explained

You've signed up to the NBN with the promise of speedier internet but how fast is NBN exactly?

Paying for premium NBN speed? Here’s how to tell if you’re getting what you’ve paid for.

The rollout of the NBN promised a faster, more reliable Australian internet infrastructure but many that made the switch have been decidedly disappointed with the results. As with any broadband technology, there’s a laundry list of reasons for why you might be experiencing broadband speeds slower than what you signed up for. And by virtue of the multiple speed choices offered, many Australians have been left scratching their heads over which NBN speed tier they need and what their internet speed should be once they’ve got it. But what is a good NBN speed? And what average NBN speed should you expect on your particular plan?

Generally, if you are on an NBN Standard plan, you should be achieving at least 40 Mbps, and if you’re on a Fast NBN 100 plan, at least 85 Mbps. These days, NBN providers are required to self-report on the speeds you can expect during typical busy hours (7 PM- 11 PM) and the ACCC does a great job of checking speed claims with its own broadband speed test report.

Let’s take a deeper look into what makes for a fast NBN connection.

The Working From Home Effect

Across the country, more Australians are working from home than ever before. This means more people at home, more often, doing more data and bandwidth-intensive tasks than before. The question is: can your NBN handle the load? Try testing your home Internet speeds in times of peak usage will give you an idea of what your current plan offers. Not getting what you hoped for? Consider signing up for a faster Internet plan, or an NBN alternative, such as Home Wireless broadband or pocket WiFi dongle.

What are the fastest NBN Plans available?

Now that we’ve taken a look at the speeds you should be expecting at each tier, let’s take a look at the providers that are leading the race for the fastest NBN plans in Australia.

These are the fastest Fast NBN 100 plans according to self-reported data from the providers.

Fastest NBN Ultrafast plans (NBN 1000)

If you’re lucky enough to be connected via Fibre-to-the-Premise (FTTP) or Hybrid Fibre-Coaxial (HFC), you might be eligible for gigabit internet speeds. Providers err on the side of caution with their self-reported speeds for Ultrafast NBN 1000, which is why you will see 250 Mbps as the typical evening speed on some of the plans below.

What is a good NBN speed?

That depends on the speed tier you’ve selected. It’s rare you will hit the maximum potential speed for any NBN speed tier but if you’re paying for Fast NBN 100 and regularly hit 100 Mbps, we’d consider that a great NBN speed.

It’s more likely you will hit closer to the average of 85.6 Mbps during busy hours, which is still great but not quite as fast as your connection has the potential for.

Each NBN speed tier has a maximum potential speed that looks pretty on paper but there many opposing forces that keep that maximum speed out of reach: the NBN technology used at your address, congestion on the network during busy hours and the available CVC at your POI all have an impact on your speed. This is why the ACCC has encouraged Australian ISPs to advertise their typical evening speeds for a more accurate figure.

If your speed test results are anywhere between the average and the maximum potential speed, let’s say 85 to 100 Mbps for Fast NBN 100, you’re getting your money’s worth.

Here’s a rough guide to give you an idea of whether your current speed tier is delivering the goods. Run a speed test while connected to your home Wi-Fi and compare the results with the table below.

Expected NBN speed quality

NBN Ultrafast (NBN 1000)0 – 250 Mbps250 Mbps to 500 Mbps500 – 1000 Mbps

If your NBN plan is delivering speeds within the Poor range, get in touch with your provider and work through some basic troubleshooting. If your speeds don’t improve, it might be time to consider another provider.

It’s possible your current provider hasn’t purchased enough CVC in your area’s POI, causing congestion on the network.

NBN speed jargon primer

With the introduction of the NBN, we’ve been forced to adopt an entirely new vocabulary of acronyms and technical jargon. Before we begin, let’s quickly explore some of the head-scratchers you’ll find in this article.


Not to be confused with megabytes (which is used to measure file size), Mbps or “megabits per second” is the metric used to measure the speed of data transfers across the internet. This standard measurement is used by internet service providers across the world. More Mbps allows you to transfer more data at once, which gives you faster downloads and more bandwidth between multiple devices.


That one’s easy. ISP stands for Internet Service Provider. Your ISP is the company that supplies your broadband connection, such as Telstra or Optus.

Typical evening speed: The ACCC has tasked ISPs with selling speeds based on real-world averages. If a network advertises 100 Mbps but can’t deliver that on average, they could land in hot water with the ACCC. This is why you will see ISPs advertise “typical evening speeds” – a more realistic expectation of what to expect when signing up to a plan.


When the NBN rolls out in a suburb, ISPs are required to purchase CVC or “connectivity virtual circuit” at that suburb’s POI or “Point of Interconnect”. CVC is essentially the bandwidth on the NBN that ISPs purchase to sell to you. The more CVC your provider purchases, the more homes it can connect in your suburb. ISPs estimate how many customers they will connect in a given area and purchase an equivalent amount CVC. If the provider underestimates the amount of CVC needed in your area, you may experience congested speeds.

How fast is NBN?

There are six NBN speed options broadband providers can sell:

  • Basic I Evening Speed: Typically less than 15 Mbps in busy hours
  • Basic II Evening Speed: Typically 15 Mbps minimum in busy hours
  • Standard Evening Plus Speed: Typically 30 Mbps minimum
  • Fast Evening Speed: Typically 60 Mbps minimum

As you can see from the list above, nbnco only advertises typical minimum speeds (to cover its butt if your NBN connection is slower than the average) but in reality, you can potentially reach much faster speeds on each tier:

  • Basic I Evening Speed: Potential 12 Mbps
  • Basic II Evening Speed: Potential 25 Mbps
  • Standard Evening Plus Speed: Potential 50 Mbps
  • Fast Evening Speed: Potential 100 Mbps
  • Superfast Evening Speed: Potential 250 Mbps
  • Ultrafast Evening Speed: Potential 1000 Mbps

Then there’s the actual average speed delivered on each speed tier courtesy of ACCC’s broadband speed tracking program (updated May 2020):

  • Basic II Evening Speed: 22.4 Mbps
  • Standard Evening Plus Speed: 42.6 Mbps
  • Fast Evening Speed: 84.5 Mbps

NBN speed tier comparison

NBN download speed

The ACCC captures real-world broadband performance data and reports those numbers to the public. We’ve used the ACCC’s broadband speed data for our averages above but it also tracks the performance of specific providers.

NBN download speeds vary between providers and are subject to change during busy hours. The ACCC reports a percentage for each provider that indicates how close on average ISPs get to delivering the maximum speed of its retail NBN plans.

For example, Optus delivers 89.3% of its maximum speeds during busy hours on average. If you’re signed up to a Fast NBN 100 Optus plan, you could expect average evening speeds (7-11 PM) of around 80-88Mbps. Of course, this percentage is an average based on a (relatively) small sample size. Average download speeds will differ from house to house. Optus also self-reports its average evening speeds at 80Mpbs but there’s a fair bit of wiggle room depending on your connection type, your property and many other factors.

ProviderDownload (busy hours)Download (busiest hours)
Aussie Broadband86.10%82.20%
Dodo & iPrimus82.50%79.00%

So there’s your particular provider’s average performance to consider but there’s one more factor that impacts your speed: the type of NBN technology you have. There are three technology types tracked by the ACCC, Fibre to the Premises (FTTP), Fibre to the Node (FTTN) and Hybrid Fibre-Coaxial.

We won’t go into too much detail around the difference here. Basically, FTTP connects your home directly to the POI over an optical network, whereas FTTN runs fibre from the POI to the existing Distribution Area (DA) pillar in your street, with copper replacing fibre in the last leg from the DA to your home. Then there’s HFC or “hybrid fibre-coaxial” which is a legacy technology the nbnco purchased from Telstra.

When it comes down to it, FTTP is the fastest NBN type because fibre is delivered to your doorstep, whereas data delivered through FTTN has a copper hill to climb between the street and your house.

The type of NBN technology you are connected with will impact your download speeds. The figures below give you an idea of the type of speeds you can expect on each technology.

NBN upload speed

Unless you upload a lot of photos or videos to the internet, or you’re planning on kicking off a lucrative career as a Twitch streamer, upload speed won’t be as important to you.

However, if you are one of the former, it could be the most important aspect of your NBN connection.

Each of the NBN tiers we’ve outlined above has a typical and average upload speed:

  • Basic I Evening Speed: Up to 1 Mbps
  • Basic II Evening Speed: Up to 5 Mbps
  • Standard Evening Plus Speed: Up to 20 Mbps
  • Fast Evening Speed: Up to 40 Mbps
  • Superfast: Up to 25 Mbps
  • Ultrafast: Up to 50 Mbps

Unfortunately, the ACCC doesn’t offer real-world upload speed averages for each speed tier as it does for downloads. But it does offer data on average provider performance for NBN upload speeds.

The best NBN plan for fast uploads

In May 2020, Exetel took the top spot for most consistent upload speeds in busy hours according to the ACCC. While the NBN 50 plan will give you perfectly reasonable uploads speeds at around 20 Mbps, you will want faster uploads if you’re planning on uploading a fair amount of content to YouTube or live streaming video games.

Here are the fastest plans from the top 3 providers for uploads speeds.
