The National Broadband Network is the largest-ever telecommunications infrastructure project in Australian history, and it is due to be completed four years ahead of time at a saving of A$30 billion.
The project itself is an Australian national wholesale open-access data network project, with both wired and radio communication components, being rolled out and operated by NBN Co.
It entails the replacement of the existing copper cable telephony network which is approaching the end of its life, and addresses the rapidly growing demand for internet access to support a growing range of services and provide broadband access to 93% of the Australian population at 100 Mbit/s.
By 2020 it is expected that all the infrastructure would have been built that enables all homes, businesses and communities across Australia to access high speed broadband.
