Optus Internet Speed Test and Guide


using the internet

The best way to see your real-world Optus internet speeds is to run a straightforward speed test yourself – something that’s crucial to check is the advertised speed that you’re paying for.

How best to run an Optus speed test

Optus offers a built-in speed test in its Optus @Home app, available for iOS and Android phones and tablets. Now, that can be great for when you just want to get a quick idea of your available speeds but remember it’ll be limited by the top speed of your phone or tablet’s wi-fi. To see your real connection speed, the best choice is to instead run our test using a desktop or laptop computer, connected to your modem via an Ethernet cable. Make sure nothing else is using your internet connection, such as downloads or streaming video, when you run the test.

Interpreting your test results

Once run, our test will show you in real time, the download and upload speeds you’re getting. The numbers are in Mbps (megabits per second), the standard way of measuring connection speed (you can divide the amount by 8 to get a rough idea of how many megabytes a second that translates to).

The download speed is always going to be the most critical number for most people – it’s the number that matters for everything from streaming video to downloading games and files

Upload speed is always lower than download speed – simply because we don’t use it anywhere near as much – thus internet service providers reduce upload speeds to compensate for higher download frequency. You should pay attention to the upload speed, though, if you share a lot of videos on Facebook or YouTube, or if you like to live-stream the video games you play. Upload speeds can be especially important for home businesses, those sharing files digitally will need better upload speeds.

Depending on the type of broadband connection you have, you may be getting less or more speed than you were expecting. Broadband plans are usually sold with a defined maximum speed, but that’s a guideline rather than a guarantee. Depending on the connection type you have – and on how you connect to your network at home – speeds can vary widely.

Don’t be alarmed if the numbers seem a little lower than what your plan claims – that’s normal. Depending on the time of day, Optus’s network can be under heavy usage (your own connection also has an amount of “overhead”), it needs some of your speed to run the connection itself.

What Speed is Optus ADSL?

Still used by many, ADSL is capable of some pretty decent speeds if you’re lucky enough to live close to the phone exchange your line connects to. The further away you are, the slower your connection (and any noise or interference on the phone line will slow things down even more). The top speed with ADSL2+ is around 24 Mbps on downloads, and approximately 1 Mbps up. But few people will reach those speeds; about 5-8 Mbps down is far more common. 

What Speed is Optus 4G?

Even though 5G’s right around the corner, 4G can provide blazingly fast download and upload speeds – it all depends on your device’s capabilities, how many cells you can connect to at the same time and how busy the network is. In ideal conditions, you can see 4G speeds as fast as 300 Mbps, but in typical day to day usage you can expect about 30-40 Mbps down, and around 5-8 Mbps up.

How Fast is Optus NBN Speed?

Optus uses the NBN 50 speed tier for its base NBN plans, meaning that your connection runs at a top rate of 50 Mbps down and 20 Mbps up. In real-world usage, at the busiest time of the evening, you can expect to see around 46 Mbps down, which is very solid NBN performance. If your speed tests are showing substantially less than that, try testing on a different Speed Test server and make sure your connection isn’t in use by other devices. The optional NBN 100 speed tier connects at 100 Mbps down and 40 Mbps up, with an average speed of about 88 Mbps during the evening peak.

For the sake of comparison consider how your Optus NBN plan compares to other popular NBN plans:

How Can You Increase Optus Internet Speed?

The easiest way to increase your Optus NBN speed is by buying a Speed Boost, which takes your NBN connection up to the highest possible speed – nearly 100 Mbps down and 40 Mbps up, which is more than enough for multiple 4K video streams, downloads and more. Optus’s Speed Boost is an extra $30 per month regardless of which plan you’re on, and it’s well worth considering if you’re sharing your connection with a large household.

How Long Does Optus Speed Boost Take to Kick In?

Once you’ve ordered a speed boost for your connection, it is normally activated on your service within the next 24 hours. It can activate a lot more quickly than that on some types of NBN (such as Fibre to the Premises) but generally, allow 24 hours. If you’re still not seeing the boost applied after that, try switching your modem/router off and on again to let it pick up on the new, improved speed.

Finding a faster broadband provider

If you are not satisfied with the Optus internet speeds or service you are receiving you may wish to consider trying a different provider.
