The simplest way to see if the NBN is available in your area is check your address directly on NBN Co’s website. This will tell you what type of connection is available at your address, so you know what to look for when comparing NBN plans.
Now that the NBN rollout has officially been declared complete, the vast majority of Australians should now have access to the National Broadband Network in some form. You can also take a look at the NBN rollout map to see what is available and where.
