Understanding nbn™ speeds

We provide a range of speed tiers on our nbn™ plans. Your actual speed can differ from the maximum line speed for a range of reasons — here's an honest rundown of the tiers, and the factors that impact what you'll experience.

Which tier suits how you use the internet?

TierDown speed up toWell suited to
Basic12 MbpsEmail, web browsing and online banking for 1–2 light users. Comparable to a good ADSL2+ connection.
Boost25 MbpsEveryday browsing and standard-definition streaming for smaller households.
Boost Up50 MbpsHD streaming, video calls, gaming and working from home in busy households.
Boost Max100 MbpsLarge households streaming on several screens at once, and small business premises.
A note on Boost Max (100 Mbps): even on a higher tier, your service speed will never exceed the maximum line speed available at your premises — particularly on Fibre to the Node (FTTN) and Fibre to the Building (FTTB) connections, where we can't confirm your maximum line speed until your service is installed and activated. We only offer Boost Max where you're eligible, and if your connection can't properly benefit from the tier you're on, we'll work with you on alternatives.

You can add or remove a bandwidth booster, or change speed tiers, at any time. Fixed Wireless connections have their own speed characteristics; ask us what applies at your address.

Factors that impact your speed

Peak periods

During busy periods — typically 7pm to 11pm — broadband speeds can slow as more premises use the internet at the same time.

Your modem

The quality and age of your modem affects performance. We recommend one of our latest pre-configured modems to get the most from your connection — contact us if yours is due for an upgrade.

Wi-Fi setup

Wi-Fi performance depends on where your modem sits, radio or electrical interference from nearby devices, and how many devices connect at once — every Wi-Fi modem has its limits. Our support team can help you tune it.

In-premises wiring (FTTN/FTTB)

If the copper lines within your premises are damaged, corroded, badly connected or poorly configured, your nbn™ speed can drop significantly.

Your devices

A slow connection on one device can point to malware, viruses, or hardware too old to support higher speeds. And when several devices download at once, your bandwidth is shared between them.

Congestion & content

Downloads can slow when the content source itself is congested — say, everyone streaming the Grand Final at once. During congestion we may prioritise time-sensitive traffic like VoIP calls and video streaming over general downloads, and those over background file-sharing, so the things that need speed get it.
