NBN Co Limited, known as simply nbn, is a publicly owned corporation of the Australian Government, tasked to design, build and operate Australia's National Broadband Network as the nation's wholesale broadband provider. The corporation reports to two shareholder ministers: the Minister for Finance and the Minister for Communications. History NBN Co was established on under the name of its company number, "A.C.N. 136 533 741 Limited". After the establishment, the Australian Government started referring to the company as "National Broadband Network Company", which became the de facto company name. It was officially named "NBN Co Limited" on . It traded as "NBN Co" until 26 April 2015 when it began trading simply as "nbn". In 2019, NBN Co announced that by May 2020 retail service providers will be able to pool all their connectivity virtual circuit (CVC) bandwidth nationally. In February 2020, the company announced that 6.7 million homes and businesses were connected to a plan over the nbn access network – compared with 4.9 million in February 2019. NBN and retail service providers As a wholesale provider of broadband access through its level two networks, NBN provides broadband access predominantly to retail service providers (RSPs); these businesses on sell access to end users; both residential and business customers to access the internet. At 30 June 2016, Telstra had 45.5%, TPG group had 24.8% and Optus had 12.4% of all end users connecting to the NBN. There has been a significant failure of the NBN to deliver nominal performance to end users. There has been contention between RSPs and NBN on the reasons for this. Bill Morrow, then CEO of NBN, admitted in 2017 that 15% of end users received a poor service through the NBN and were 'seriously dissatisfied'. In addition, Morrow indicated that, at July 2017, prices and performance for end users were suppressed through a 'price war' between RSPs. Contractual arrangements NBN contracts mainly with RSPs to provide wholesale broadband access, with limited supply of backhaul to other organisations (for example providing backhaul services to Vodafone). National Broadband Network Under the Gillard/Rudd governments' NBN Co corporate plan, it was estimated that the NBN construction would require A$27.5 billion in government equity and raise an estimated A$13.4 billion in debt funding without government support; a total funding requirement of A$40.9 billion up to FY2021.
