Speeds on the NBN network explained

This article will provide information about the speed abilities of different nbn™ technologies, and the various factors which can affect the speeds which individual users experience.

Select one of the links below to jump to a query:

General Factors that can affect all broadband speeds

  • Hardware: You will need a router capable of connecting you to the nbn™ network which can handle the high speeds available to you. WiFi within the premises and router performance can often be the slow point in a nbn™ connection.
  • Network links: External network factors such as physical location of host computer, global Internet link between iiNet and the destination and the backhaul network between your premises and iiNet. Congestion on domestic and international links can be present during peak times.
  • Users: The amount of local users and devices in use at one time. Even with the high speeds of the internet it is possible to use all available bandwidth at once, which will affect the overall speed experience.
  • Software: There are many applications and programs that access the Internet. These may be running in the background on your device performing various activities such as downloading updates and files and uploading information... all of this will cause you to lose a 'bit' (or several) of your total speed.

 

Specific Factors

Different nbn™ technologies have different speed abilities, and the nbn™ plan you select may have different speed options available. Think about the maximum speed of your plan as the speed limit on a freeway. Although there is a speed limit, you may not always reach this speed due to various factors such as traffic and weather. Just like achieving the speed limit on the freeway, you may not achieve the maximum speed on your plan. Actually, in most cases, maximum speeds will not be experienced in full.

In addition to the general factors that can affect all broadband speeds, the specific factors below may affect the actual speed experienced on your nbn™ service.

HFC Optical fibre leading to a Node in your street or a street nearby, with a final stretch of hybrid fibre-coaxial (HFC) cable to your premises. HFC Cable will connect to your nbn™ Utility Box on an outside wall and wire internally to your nbn™ HFC modem. Max speeds are up to 100Mbps downloads, 40Mbps upload. See General Factors
Long Term Satellite Service (LTSS) Satellite dish on your roof communicates with the nbn™ satellite, with internal wiring to your nbn™ Satellite Connection Box. Basic: Up to 12Mbps download, 1Mbps upload.
Boost: Up to 25Mbps download, 5Mbps upload.
Weather conditions (either at premises or base station location)

Satellite congestion.

Obstruction of the dish’s line of sight (weather conditions).

^Actual  throughput speeds may be slower and could vary due to many factors including type/source of content being downloaded, hardware and software configuration, the number of users simultaneously using the network and performance of interconnecting infrastructure not operated by iiNet. Devices connected by WiFi may experience slower speeds than those connected by Ethernet cable.
 

Choosing the right speed for your household

Speed Wholesale Connection Speeds^ Advice about choosing this speed
Up to 12Mbps download, 1Mbps upload. A basic speed to cover the essentials. Ideal if you're a small household with one or two devices connected. If you're unsure which speed you need, it's a great place to start. You can always upgrade later.
