Is an NBN 100 plan right for me?

NBN 100 is great for larger families where 3 to 4 people are actively online, even simultaneously.

It may also suit a smaller household that loves using the internet for gaming, watching 4K streams, working from home together, taking frequent video calls and downloading large files.

What's the difference between NBN 100/40 vs 100/20 plans?

The main difference between 100/40 and 100/20 plans are the upload speeds. 100/40 plans come with upload speeds of 40Mbps, while 100/20 come with 20Mbps upload speeds.

While download speeds are usually what people focus on, those spending their time at home taking video calls or sharing large files may want a faster upload speed, which is where a 100/40 plan would come in handy. Otherwise 100/20 should do you just fine.

  • Good to know: 100/20 plans are slightly cheaper because you get a slower upload speed. There's around a $9 per month difference in the cheapest unlimited data NBN 100/40 and NBN 100/20 plans on Finder.

Is it worth getting NBN 100?

If you're in a household where the internet is often used for streaming and heavy online work, an NBN 100 plan could be suitable.

However, there's a reason the NBN 50 speed tier has maintained its popularity to this day as a great standard speed. It could be worth testing out before you take a step up to NBN 100 and pay a higher price, especially if you aren't sure your NBN connection type can achieve those speeds.
