The National Broadband Network

The National Broadband Network (NBN) was a government-led initiative to modernize the country's telecom infrastructure. In 2022, Australia's National Broadband Network (NBN) was made up of a variety of technologies, with 35.5 percent of connections made via Fiber to the Node (FTTN). A long-term satellite serves about one percent of the connections that cannot be served by fiber cables. NBN Co, an Australian government-established corporation, oversaw this. Internet service providers enter contracts with the NBN to gain access to the wholesale market, and then sell internet packages to Australian consumers who use this infrastructure.
