Equipment connected over the nbn™ network will not work during a power blackout. Below is more information about how each technology used in the nbn™ Multi Technology Mix (MTM) is affected by power loss.

Fibre to the Premises (FTTP)

With Fibre to the Premises (FTTP) nbn supplies and installs a connection box within your home or business which requires power to operate. Optional battery backup is available from nbn, but you need to speak to your service provider to order a telephone service that uses the battery backup. This service needs to be used with a telephone that does not require mains power to be able to operate during a blackout. Unless you have battery backup and a corded phone correctly connected, your phone won’t operate in a blackout.

Battery Backup is required for Priority Assistance customers. If you have a life-threatening illness, please discuss this with your service provider.

During a power blackout, battery backup may last for approximately five hours (this includes the battery emergency reserve which offers approximately three to three and a half hours initially, and around another one and a half hours once the ‘Battery Emergency’ button is pressed). All mains powered equipment connected to the nbn™ network will need its own separate battery backup to work in a power outage. Further information is available in the FTTP user guide.

Fibre to the Node (FTTN)

Landline phone and internet services won’t work if there is a power outage either within the FTTN network or within your premises. Restoring power to your premises with an alternative power option will have no effect if the FTTN network is also experiencing power loss. You should consider keeping a charged mobile phone in case there is a power outage of any sort.

Fibre to the Building (FTTB)

Landline phone and internet services won’t work if there is a power outage either within the FTTB network, your building or within your premises. Restoring power to your premises or whole building, with an alternative power option will have no effect if the network outside your building is also experiencing power loss. You should consider keeping a charged mobile phone in case there is a power outage of any sort.

HFC (cable)

Landline phone and internet services won’t work if there is a power outage either within the HFC network or within your premises. Restoring power to your premises with an alternative power option will have no effect if the HFC network is also experiencing power loss. You should consider keeping a charged mobile phone in case there is a power outage of any sort.

Fixed Wireless (FW)

Landline phone and internet services won’t work if there is a power outage at the nbn™ Fixed Wireless Tower, backbone network or within your premises. Restoring power to your premises with an alternative power option will have no effect if the nbn™ Fixed Wireless Tower is also experiencing power loss. You should consider keeping a charged mobile phone in case there is a power outage of any sort.

When ordering an nbn™ service in a Fixed Wireless area, have a discussion with your current service provider about your existing landline. If you have an existing copper phone line it is important to consider keeping it in service for emergency communications, especially if you don’t have good mobile phone coverage at your home or business.

Sky Muster™ (Satellite)

If there is a power outage at your premises, restoring power with an alternative power option will usually enable you to reconnect to the Sky Muster service. However, if one of the nbn™ Sky Muster satellite ground stations is also experiencing power loss, there may be further delays in reconnecting your service.

When ordering an nbn™ service in a Sky Muster™ area, have a discussion with your current service provider about your existing landline. If you have an existing copper phone line it is important to consider keeping it in service for emergency communications, especially if you don’t have good mobile phone coverage at your home or business.
