NBN Speeds for 1440p vs. 1080p Streaming: What Do You Really Need?

Direct Answer & Analysis

For smooth streaming, your NBN plan needs to comfortably exceed the bitrate of your content. For 1080p (Full HD) streaming, an NBN 25 plan is sufficient. For a stable 1440p (QHD) experience, an NBN 50 plan is the recommended minimum.

Here’s the technical breakdown:

1080p (Full HD): Platforms like Netflix and YouTube require approximately 5-8 Mbps (Megabits per second) of download speed for a consistent 1080p stream. An NBN 25 plan, which offers a typical evening speed of around 22-25 Mbps, provides more than enough bandwidth to handle this, even with other devices occasionally using the network.
1440p (QHD): This higher resolution demands a significantly higher bitrate, typically in the range of 10-16 Mbps on platforms like YouTube. While an NBN 25 plan might technically handle this in perfect conditions, it leaves no room for other users or background processes. Any network congestion will likely cause buffering. An NBN 50 plan, with typical evening speeds of 45-50 Mbps, provides the necessary headroom for a flawless, buffer-free 1440p stream.

Resolution	Recommended Minimum Speed	Recommended NBN Tier	Why?
1080p (Full HD)	~8 Mbps	NBN 25	Offers ample headroom for a stable stream and light background usage.
1440p (QHD)	~16 Mbps	NBN 50	Guarantees enough bandwidth to prevent buffering, especially in a multi-user household.
