How the network comes together

The nbn™ network is just one part in a mixture of network services – many of which are outside of nbn’s control.

Here we look at how the network comes together, giving you a clear understanding of all the elements involved and how they can affect your internet speed and performance.

Below you’ll find a simplified version of the network – illustrating all the elements involved and providing clarity around who is responsible for what.

Who does what?

nbn is responsible for the technology connecting your premises to the nbn™ network.

Your phone and internet service providers are responsible for everything from plans and pricing to the speed and capacity you enjoy when you access an international website. It’s important you take this into account when selecting which service provider you go with.
