Adjacent Fibre Network Extension

The National Broadband Network (NBN) is one of the largest infrastructure projects in Australia's history. Because of the size of our country, we will also need to use fixed wireless and satellite technology to connect those premises that do not fall into the fixed line footprint.

The national deployment approach allows NBN Co to provide for 100 percent of premises to be connected to the National Broadband Network providing a step change in broadband infrastructure and also support a uniform national wholesale price so that no matter where people live the same wholesale access price will be available.

What is an Adjacent Fibre Network Extension?

The Network Extension policy is under review, pending the outcome of the Government’s reviews into the National Broadband Network. 

The network extension program is a process created for businesses or individuals to fund an extension of the fibre network to their premises. This gives Australian households, businesses and other premises the ability to choose, where possible, an alternative technology through which they can access the NBN.

Adjacent Fibre Network Extensions are currently only available to premises that are located adjacent to areas where fibre services are already available or construction of NBN Co’s fibre network has started.

Is a Network Extension right for you?

There are three things to consider if you are assessing whether to apply for a network extension:

  1. You must be in the 7 percent of premises that will be on fixed wireless or satellite services and located in an area adjacent to an area that is currently serviced by fibre or where construction of the fibre network has started.
  2. You are seeking an alternate technology to what you have been provided e.g. changing from satellite  or fixed wireless to fibre.
  3. You must be willing to fund the incremental cost of extending the fibre or fixed wireless network to your property. 

Currently, Network Extensions for whole towns or the fixed wireless network are not available, pending the introduction of new government policy.

If you already know you meet these criteria find out about our application process.

Fixed wireless or satellite areas

NBN Co's fixed wireless network is designed to offer retail service providers with wholesale access speeds of up to 25Mbps. This is comparable to, and in some cases better than, that available in many urban areas that currently receive ADSL2+ services. The Long Term Satellite Service is expected to be configured for wholesale access speeds of up to 25Mbps download and 5Mbps upload*. Before submitting an application for a Fibre Network Extension, you should consider whether the services that will be provided over NBN Co's fixed wireless and satellite network will be suitable for your needs.

Who can apply for a network extension

Applicants can be individuals, businesses, government bodies and other similar entities.

All applications for Network Extensions must be submitted by:

  1. the owner of the property, or
  2. a person having the written authority of the owner of the property to undertake or procure the undertaking of construction work in respect of the property).

All Network Extensions will be subject to agreed terms and conditions for the network extension. Where the applicant is not the owner of the property receiving the network extension, additional provisions will apply to ensure that the owner of the property has provided the necessary authority (NBN Co may request a copy of this authority at any time up until 7 years after the applicable Network Extension is completed).


* NBN Co is designing the NBN to be capable of delivering high speeds to NBN Co's wholesale customers (telephone and internet service providers) via fibre, fixed wireless and satellite. Speeds actually achieved by retail customers (end users) will depend on a number of factors including the quality of their equipment and in-premises connection, the broadband plans offered by their retail service provider and how their retail service provider designs its network to cater for multiple end users..
