The National Broadband Network (NBN) is an Australian national wholesale-only, open-access data network. It is based on the premise that access to fixed line, wireless and satellite broadband connections are sold to retail service providers (RSPs), who then sell internet access and other services to consumers. The NBN was subject to political and industry debate and radical change after the 2013 federal election.
