What do the NBN service classes all mean?
Unlimited NBN Plans from $44.90/mth - See Plans
nbnTM is Australia's new broadband network and is currently being built across Australia.
Every address in the country is mapped by nbnTM and NBN will be delivered to each address in certain way. This could be fibre to the premises, fibre to the node or building, fixed wireless, HFC, NBN satellite or via the latest technology type fibre to the curb. NBN keeps track of the stage of their NBN build and the readiness of a particular address by using service classes.
Every address has a service class and the service class may change as the build of the new network progresses.
