Modifying nbn™ broadband access network
infrastructure
We recognise our nbn™ assets or infrastructure may occasionally need to be altered, relocated, removed or protected.
It’s important to note that by law, only nbn and our authorised contractors may work on nbn™ assets and infrastructure. This means that any interference, including unauthorised tampering, damage or modifications, may result in legal action. nbn reserves all of its rights in relation to the cost of recovery, reinstatement and repair of assets and infrastructure impacted by unauthorised works. However, some cabling work may be performed by registered cablers. For more information please visit our cabling page.
Keep in mind, nbn is a member of Dial Before You Dig. To help avoid accidental damage and costly repairs, please ensure you’re aware of the location of any underground cables in your area. Simply contact Dial Before You Dig on 1100 or via the Dial Before You Dig website. This will help you to minimise the risk of serious damage to our assets - or other utilities such as power, gas or water – and will help to ensure that critical services in your community keep working.
Apply early and provide nbn with as much advance notice of your plans as possible.

- Relocation of aerial network or lead-ins underground

If the equipment has already been removed and you’re ready to re-connect and re-install, please speak to your phone or internet service provider.

nbn™ assets and infrastructure
on public land
- Relocation of nbn™ street infrastructure (e.g. nodes, pillars)
- Relocation of nbn™ pits and assets in pits owned by nbn or another telecommunications provider
- Relocation of nbn™ conduits.
If you are planning future road works, you may need to consider relocating our conduits so that the depth is maintained and the conduits remain accessible.
This application is a request for Commercial Works, which we will assess and confirm eligibility.
Before you start
In some instances, you may not need to submit a Commercial Works application. You could consider optimising your internet connection by first speaking to your phone and internet provider about your specific needs. You can also contact your provider directly for all issues relating to:
- Reinstallation of missing equipment (including nbn™ supplied equipment located inside or attached to your premises)
- Workmanship issues relating to the installation of nbn™ supplied equipment.

Application fees
Each application will incur a Commercial Works fee. You may also incur an Application Fee depending on the size and complexity of your proposed works.
The Application Fee covers the preparation of the cost estimate for the proposed works, which we may need to prepare by consulting with other parties. An nbn™ Case Manager will confirm which fees apply upon assessment of your application.

All of our Commercial Works are payable by the party requesting the work. This fee must be paid before any work begins.
