The National Broadband Network (NBN) is a national wholesale-only, open-access data network under development in Australia. Up to one gigabit per second connections are sold to retail service providers (RSP), who then sell Internet access and other services to consumers. The NBN has been subject to political and industry debate for a number of years, before construction actually commenced.
The network is estimated to cost A$35.9 billion to construct over a 10-year period, including an Australian Government investment of A$27.5 billion. The build cost has been a key point of debate. NBN Co, a government-owned corporation, was established to design, build and operate the NBN, and construction began with a trial rollout in Tasmania in July 2010. The mainland rollout began with five first-release sites with the first services connected in April 2011.
The fibre to the premises (FTTP) rollout is planned to reach approximately 93 percent of the population by June 2021. Construction of the fixed wireless network is planned to begin in 2011, delivering its first services in 2012 and to be completed by 2015. Two satellites will be launched by 2015. The network will gradually replace the copper network, owned by Telstra and currently used for most telephony and data services. As part of an agreement with NBN Co, Telstra will move its customers to the NBN, and lease access to its exchange space and extensive network ducting to assist in the rollout.
