How we advertise NBN™ speeds

In order to help Australians make informed choices when it comes to the NBN™, Westnet 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, Westnet 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 (Fast): Typical evening speed 90Mbps download
  • Premium (Superfast): Typical evening speed 200Mbps download^
  • Premium (Ultrafast): Typical evening speed 200Mbps download^

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

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

  • NBN™ Infrastructure
    For example, the length and quality of copper cabling used in NBN™ FTTN/FTTC/FTTB has a significant impact on performance.
  • Coexistence period
    NBN™ FTTN/FTTB /FTTC services are typically limited during the period they must share the same copper line as legacy non-NBN™ services.
  • Quality and capability of hardware
    This can include modems, WiFi routers and Ethernet or phone cables.
  • WiFi signal interference
    You can learn how to improve your home or office’s WiFi signal here.
  • Number of connected devices
    When too many devices share the same bandwidth, data flow is limited.
  • Network Congestion
    For example, when speeds slow during peak traffic in the evenings.
  • Which content is being accessed
    There may be insufficient server capacity or other issues affecting a specific website or online game.
