NBN100 plans are one of the fastest NBN speeds currently available. It offers maximum speeds of up to 100Mbps, though your actual speed will depend upon your connection type, network congestion and your provider.

These kinds of plans suit households of four or more heavy users, or a few extremely heavy users who enjoy streaming high-definition video or downloading large files.

Fast NBN 100 plans explained

A "Fast" NBN100 plan offers maximum download speeds of 100Mbps and upload speeds of 40Mbps, making it the third fastest speed tier that you can buy in Australia. Not only do they allow for quick downloads and uploads for individual users, but they also allow multiple users to do these activities all at once on the same connection when slower connections might struggle.

  • Download speeds refer to how fast it takes you to download things from the Internet, e.g. browsing (you're essentially downloading a webpage to view), streaming content, social media and downloading files.
  • Upload speeds are how fast it takes for you to upload things onto the Internet such as uploading photos onto social media or uploading videos onto YouTube.

Some providers will offer NBN100 plans with max upload speeds of 20Mbps for less than a 40Mbps upload speed might cost you, which might suit you if you don't need to upload often. Keep in mind that you'll have to fork out a little extra for Fast plans, since you're getting more speed - they will routinely cost about $20 to $30 more than the next speed tier down, NBN50.

How fast is NBN 100 speed?

NBN 100 - or Fast speed NBN - used to be the fastest NBN speed tier available to customers in Australia. Since June 2020, faster tiers are not available but that doesn't make NBN 100 pale in comparison. For most larger households who need a quick Internet connection, NBN 100 should meet those needs just fine. With maximum download speeds of 100Mbps, users should theoretically be able to download 12.5MB every second. This means you could download a 2-hour HD movie in just under 7 minutes.

Here's how fast it would take to download or upload a number of common files on various NBN speed tiers, assuming that each one is running at maximum speed the whole time. Keep in mind that NBN speeds are given in megabits per second (Mbps), with 8 megabits adding up to a single megabyte (MB).

More on NBN speeds

Even if you're after the fast NBN speeds, that doesn't necessarily mean that you need an NBN100 plan. For a household of 2 people who love ultra-high-definition video streaming and extensive video gaming, an NBN100 plan is likely to be way more than they need and they could easily get away with an NBN50 or even an NBN25 plan for a much reduced cost. NBN100 plans are more useful for larger households (4 or more) of high-intensity Internet users, so that everyone can do their activities without the connection slowing down considerably.

Always keep in mind that even with an NBN100 plan, you will rarely if ever actually experience the maximum speed of 100Mbps. The factors which impact your actual speed include:

Here are the main types of people an NBN100 plan suits:

  • Several heavy Internet users. If there are 3 or 4 people who enjoy really high-resolution streaming of videos and are constantly downloading or uploading large files in your household, NBN100 could be suitable.
  • Many medium users. When you hit 5 or 6 people in a household who are using the Internet frequently at the same time, an NBN100 plan could be required just to have enough bandwidth for everyone.
  • Small businesses. If you're running a small business with several employees, an NBN100 plan might be needed for your various operations.

It's worth thinking about your needs when considering whether or not to buy an NBN100 plan because it will cost you a great deal more in the long term than the next step down. If you think you need one, consider starting at an NBN50 plan that doesn't have a lock-in contract and then upgrading if it turns out that you need more.
