When choosing an NBN plan, many Australian households and businesses compare NBN 100/40 plans with NBN 100/20 plans. While both speed tiers offer download speeds of up to 100 Mbps, the key difference lies in their upload speeds. Understanding how this affects daily internet usage can help you select the most suitable plan.
Understanding NBN Speed Tiers
NBN plans are typically named according to their maximum download and upload speeds. In this case:
- NBN 100/40 offers up to 100 Mbps download and 40 Mbps upload speeds.
- NBN 100/20 offers up to 100 Mbps download and 20 Mbps upload speeds.
Because the download speed is the same, activities such as streaming, web browsing, and downloading files will perform similarly on both plans. The main distinction becomes noticeable when uploading data.

may benefit from choosing NBN 100/40 plans.
Cost Considerations
NBN 100/20 plans are generally more affordable than NBN 100/40 plans. If internet usage mainly involves streaming, browsing, and occasional video calls, the lower-cost option may offer better value.
However, users who regularly upload content may find that the productivity benefits of NBN 100/40 justify the additional cost.
Conclusion
The choice between NBN 100/40 plans and NBN 100/20 plans depends largely on upload requirements. Both provide fast download speeds, but NBN 100/40 offers double the upload capacity, making it ideal for remote work, content creation, cloud computing, and business applications.
