The simplest way to look up the NBN connection at your home is to use the address check tool through NBN Co. This is an extremely simple function which enables you to search the relevant address and find out if the NBN is available where you live or work.
Once you’ve filled in the relevant address, it’ll tell you whether you’re connected to the NBN and the type of connection available. It’s also useful if you’re unsure about what connection type is in place at your home. For example, if your search shows that you’re connected (or can be connected) to the NBN via a Fibre to the Node (FTTN) connection, this will inform the plans you can choose from, as FTTN only supports those up to NBN 100.
The NBN check tool on the NBN Co website also allows you to search for outages if your connection has dropped out. This is one of the first steps to take in the event of an NBN outage, as it’ll help you determine whether the outage is present in your wider area due to maintenance or if it’s localised purely to your property.
There are also other similar resources you may be able to use to find out this information, such as a tool on your provider’s website (if available). These can be particularly useful for outage purposes, as NBN Co won’t necessarily keep you updated with connection issues specific to certain providers.
