NBN™ Speeds Explained

Our core network and NBN CVC’s are monitored daily, to ensure there is always ample headroom above peak network demand, however, we cannot guarantee that your service will operate at full speed, or the same speed at all times.

There are many factors that can affect the speed of your service. These include your selected speed tier, general factors that can affect most types of broadband services and nbn™ specific factors which are outlined below.

If you are experiencing slow speeds please contact Technical Support.

If it is established that your line is not capable of supporting your chosen speed tier you will have the option to remain on your selected plan, move to a lower speed plan at no cost (if available) or cancel your service and exit your contract (if applicable) without penalty.

Maximum Download & Upload Speeds

The speed tier you select determines the maximum possible download and upload speed your service can receive (as provided by NBN Co) and is not necessarily indicative of the internet data transfer/throughput speeds your connection will achieve in practice. The actual data transfer/throughput speed will be unknown until the service is connected and may be substantially lower than the maximum speed for a variety of reasons.

Speed TierMaximum Download/Upload
nbn1212/1 Mbps
nbn2525/5 Mbps or 25/10 Mbps if it is Business NBN over the fixed line network

OntheNet is unable to provide typical speeds for National plans or services that are delivered over the nbn™ fixed wireless network.

Just like other broadband technologies, there are many factors that can affect the actual speed of your service, such as:

  • The number of simultaneous users,
  • The type of CPE and software in use and its configuration,
  • The source/type of content being downloaded by the user,
  • Environmental/external influences that may impact the speed and/or performance of the service,
  • The TCP/IP software settings on the Customer’s computer and how the applications use TCP/IP,
  • The capacity of the remote server the Customer is accessing,
  • The presence of congestion at any point between the remote server and the Customer’s computer,
  • The highly variable performance of wireless networks (Tips to improve your wireless performance),
  • The bandwidth profiles for all services supplied to the NBN Connection Box (by OntheNet or another provider) exceeding the throughput limit of the NBN Connection Box.

For Personal NBN™ plans specifically, the service will be Shaped (slowed) to 1Mbps if the included data allocation is exceeded, until your next anniversary date. This is not applicable to our Business NBN™ plans.

Other factors can affect the performance of your NBN service, depending on NBN technology that is being used to deliver your service. If you are unsure what type of NBN technology is connected to your premises please contact us.


  • Length and quality of the copper line from your premises to the building MDF.
  • The number of joints in the copper line.


  • Length and quality of the copper line from your premises to the nbn™ node.
  • The number of joints in the copper line.
  • Weather conditions.
  • Co-existence period – if applicable, speeds above 12/1 Mbps may not be achieved.


  • The number of premises/users sharing the coaxial cable that connects to your premises.
  • The number of HFC/cable devices in use at your premises eg NBN, Pay TV.

Fixed Wireless

  • Weather conditions.
  • Signal strength.
  • Obstruction of the wireless antenna’s line of sight to the nbn™ wireless tower.
