How we advertise NBN™ speeds

In order to help Australians make informed choices when it comes to the NBN™, iiNet was amongst the first Internet Service Providers to follow recommendations from the Australian Competition and Consumer Commission (ACCC) to advertise typical evening speeds for NBN™.

Typical Evening Speeds are subject to change and are measured 7pm-11pm. Speeds are not guaranteed and may vary.

As of 2 June 2021, iiNet advertises the following speeds for NBN™ FTTP, FTTB, FTTN, FTTC & HFC services:

  • Basic (NBN12): Typical evening speed 12Mbps download
  • Standard (NBN25): Typical evening speed 25Mbps download
  • Standard Plus (NBN50): Typical evening speed 50Mbps download
  • Premium (NBN100): Typical evening speed 90Mbps download
  • Premium (NBN Superfast): Typical evening speed 200Mbps download^
  • Premium (NBN Ultrafast): Typical evening speed 200Mbps download^

^NBN FTTP & HFC only. Estimated speeds for these new plans will be revised once iiNet has collected enough performance data. A high speed modem is required.

iiNet Business NBN™ services measure typical speeds during weekday business hours (i.e. 9AM – 5PM local time) as this is more useful to business customers. View iiNet Business NBN™ plans.

Factors affecting speeds

Different NBN™ technologies have different speed abilities, and the NBN™ plan you select may have different speed options available.

General factors that affect all technologies

  • 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.

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.
