NBN speed test: check your broadband speed here in seconds

Find out just how "ultrafast" your connection really is

So the NBN rollout has finally reached your place, and you’ve been set up with a brand new high-speed connection — the supposedly ultrafast broadband service that has been in the works for over five years by this point... and now you want to put it to the test. 

Maybe it’s been giving you grief and under-delivering on what your ISP (Internet Service Provider) seemingly promised, or maybe you just want to see how speedy it truly is. On this page, you'll be able to test your speed, see what it means, and get the most out of your home connection.

To kick things off quickly, simply hit 'start test' below and Measurement Lab's tool (as used by Google) will run a diagnostic on your connection, spitting out both a download and upload speed. This can give you a quick overview of how your net is doing, but for more info, keep scrolling.

What to expect

If you want to test how your connection is operating, it’s probably a good idea to check out how it should be operating so you can compare.

When signing up for the NBN, you would have chosen a speed-tier from the options provided by your ISP — this will dictate the upper limit of both the download and upload speeds you’ll be able to hit, although that number isn’t indicative of the actual speed you will experience at all times.

NBN Co. offers 12, 25, 50, and 100Mbps options for residential customers, but because the company is a wholesaler, it ends up being the decision of each ISP as to what speeds they will offer to their customers. Typically ISPs have plans that reflect either three or four of those speed-tiers, but this won’t always be the case.

By law, your ISP has to advertise something referred to as a "typical evening speed", which is an average that's indicative of how fast your download rate should be going during the busy period of the day – when most people are at home and using streaming services.

As is becoming popular, you'll get a bit of a discount on your first few months – 6 months specifically – but even once the price then jumps up an extra AU$15 per month, it's still the best value NBN100 plan on the market right now thanks to its unlimited data, solid evening speeds (83Mbps), and no lock-in contract. With this offer, you can either BYO modem or spend AU$129.90 up front to get one from Tangerine direct. Total minimum cost is AU$74.90View Deal


You've already run the test above by this point, we assume, but  you should have another go to try and give your internet the best chance it’s got at achieving high speeds so you can accurately measure the signal arriving at your house. 

Where possible, connect your computer or laptop directly to your modem or router with an Ethernet cable, and avoid running any downloads, streams or other data-heavy activities and programs while the test is in progress.

If you have to test your connection over Wi-Fi, such as with a laptop or smartphone, try and move as close as possible to your router to ensure you have a strong wireless signal, as a weak one can interfere with the internet speed testing, meaning you’ll see lower results than your ‘net connection is actually capable of.

Once you’ve set yourself up, it should just be a matter of hitting the ‘start test’ button and waiting for the test to run its course. Once completed, you’ll be given a download speed and upload speed, both measured in Mbps, as well as some more advanced diagnostics if you're so inclined.

We suggest running this test several times to ensure you’re getting consistent results each time. If the results are wildly erratic or vastly below the expected amount, try rebooting your modem and re-running the test.

Diagnosing the results

Don’t be alarmed if the download speed isn’t bang-on the number promised to you by your provider — it’s rare to get 100 percent of promised speed — however, it should be close if everything’s gone smoothly so far.

Certain factors will affect this speed, such as how many devices or active tasks are using the connection simultaneously, as well as the type of connection you have. Fibre to the node (FTTN) connections, for instance, will experience slower speeds the further away your premises are to the node itself; apparently distances above 400-500 metres will start seeing a decrease in real-world vs promised speeds.

If you’re experiencing significantly lower speeds than listed on your plan and have already tried all the aforementioned tricks, then you should contact your service provider to see what the issue is. They should be able to tell you how far away you are from the node if you’re on a FTTN connection, or if there are some specific problems in your area otherwise.

Need a better plan?

Still not happy with the results? Maybe it’s time to check out a higher-speed NBN plan, or switching to another provider entirely. Below, we've got a live-upated tracker to compare plans, but we've also got two dedicated pages to help you out, one for the fastest NBN plans available, and another that compares the best value NBN plans on offer.
