National Broadband Network


What is the National Broadband Network?

The National Broadband Network (NBN) will ensure that all Australians have access to very fast broadband using a mix of technologies. The Australian Government is committed to completing the construction of the NBN sooner, at less expense for taxpayers and more affordably for consumers.

Variation of Telstra's Migration Plan: Finalisation of Regulatory Instruments

On 27 January 2015 the Government finalised two regulatory instruments supporting the variation of Telstra's migration plan:

The instruments were developed in consultation with Telstra and NBN Co and finalised following consideration of submissions received via a public consultation process conducted between 16 December 2014 and 7 January 2015. The consultation paper from this process, and all non-confidential submissions received, can be viewed at the Submissions to the Variation of Telstra’s Migration Plan consultation paper webpage.

Finalisation of the instruments allows Telstra to lodge its revised Migration Plan with the Australian Competition and Consumer Commission (ACCC) for consideration. Telstra’s Migration Plan supports its structural separation by outlining the steps the company must take to disconnect voice and broadband services on its copper and hybrid fibre-coaxial (HFC) networks in the course of migrating customers to the fixed-line NBN. The making of the revised Migration Plan is a key step in moving to the multi-technology mix (MTM) National Broadband Network (NBN).

The instruments set out the matters that Telstra’s Migration Plan must cover and the manner in which the Migration Plan must deal with those matters.  

Commercial Agreements to support the NBN

On 14 December 2014 NBN Co signed amendments to its commercial agreements with Telstra and Optus that will facilitate the multi-technology mix NBN.  Under the agreements NBN Co will progressively take ownership of many parts of Telstra’s copper and HFC cable networks, as well as Optus’ HFC cable network, and will use this infrastructure in the NBN.  The amendments are subject to a number of Conditions Precedent, including relevant regulatory approvals.

Implementation of the National Broadband Network: Migration Assurance Policy Consultation Paper

On 2 September 2014 the Government released a consultation paper seeking feedback from all interested stakeholders on the best way to reform the migration of services to the National Broadband Network (NBN). Submissions in response to the consultation paper closed on 26 September 2014. More information, including a list of the submissions, is available on the Migration Assurance Policy Consultation Paper page.

Cost Benefit Analysis of National Broadband Network

On 27 August 2014, the Government released the Cost-Benefit Analysis of the NBN prepared by the panel led by Dr Michael Vertigan AC.

Please note: These documents are not completely accessible due to the redaction of some content.

The Cost-Benefit Analysis confirms that there are real economic and social advantages in deploying high-speed broadband infrastructure to Australian households and businesses.

The Cost-Benefit Analysis considers the costs of different approaches to providing fast broadband in Australia. It also considers preferences and potential future demand f

Statement of Expectations

The Government has issued NBN Co with a new Statement of Expectations. This statement will guide the next steps in delivering the NBN. It replaces the interim Statement of Expectations issued in September 2013 and all previous statements.

NBN Co Review

The Government has committed to undertake a series of reviews into the NBN in order to refocus the rollout around its policy objectives which include using a wider range of technologies to connect homes and businesses to the network sooner. The individual reviews will cover:

  • NBN Co's costs, structure, commercial prospects and strategic plans
  • the public policy process which led to the NBN and NBN Co's governance
  • the economic and social costs and benefits of the availability of high speed broadband of differing properties via various technologies, the role of Government support and a number of other longer-term industry matters.

On 3 October 2013, the Minister outlined the Terms of Reference for the first of these reviews, which has been undertaken by the new NBN Co Board. The Government received a draft of NBN Co's Strategic Review on 2 December 2013. On 12 December 2013, NBN Co published the Strategic Review into the NBN rollout after detailed consideration. Further information on the conduct and timing of the other reviews will be provided as decisions are announced by Government.

Independent Audit of the NBN Public Policy Process

On 7 March 2014, the Government announced the appointment of Mr Bill Scales AO to conduct an independent audit of the public policy processes that led to the establishment of the NBN.

The Scales report is published online on the Australian Parliament House website. A copy of the report published on that website can be accessed here.

More information on the audit can be found on the Independent audit of the NBN Public Policy Process page.

Cost-Benefit Analysis and Review of Regulation

On 12 December 2013, the Government announced the terms of reference for the Cost-Benefit Analysis and Review of Regulation of NBN (the third of the reviews listed above) and the Panel of Experts who will provide a report to the Government.

The panel has provided the following reports to the Government:

  1. The Statutory Review of Part XIC of the Competition and Consumer Act 2010 (the Statutory Review). The Statutory Review was tabled in both Houses of Parliament on 16 July 2014.
  2. The Independent Cost-Benefit Analysis of Broadband. This was released on 27 August 2014.
  3. The NBN Market and Regulatory Review. This was released on 1 October 2014.

Broadband Availability and Quality Project

The Department of Communications has undertaken a comprehensive analysis of broadband availability and quality in over 78,000 local areas of Australia to assist with the prioritisation of the National Broadband Network (NBN) rollout.

On 20 February 2014, the Minister for Communications published the full results of this analysis, following the release of a national summary report on 23 December 2013.

The full Broadband Availability and Quality Report compares the broadband technologies available to Australians in every part of the country and the download speeds that can typically be achieved over each platform. A complementary website, MyBroadband, allows people to view results for their local area and provide feedback on the broadband quality and availability ratings.

The Broadband Availability and Quality report has been provided to NBN Co. The company has been asked to consider the findings and prioritise construction work in underserved areas of the country, where is it logistically and commercially feasible to do so.

The report found that deploying the NBN through a multi-technology mix (MTM) – which involves a combination of fibre to the premises (FTTP), fibre to the node, hybrid-fibre coaxial, fixed wireless and satellite technologies – provides net benefits of $18 billion to the community and the economy.

MTM produces these benefits because it can be delivered quicker and at less cost, improving broadband access for Australians who really need it. The report also found that MTM is far more 'future proof' in economic terms: if future demand grows slower than expected, it avoids the high sunk costs of having deployed FTTP. MTM also provides the option of future upgrades to FTTP, once there is sufficient demand to make it worthwhile.

The Cost-Benefit Analysis also drew from the following work:
