G.fast is a broadband technology that sends very high speeds over the short copper line between a nearby node and your home. In Canberra it runs on the Vision Network, the former TransACT network, which is separate from the nbn. Infinite sells G.fast plans up to 1 Gbps/100 Mbps. In our 2026 data the average connection synced at 694 Mbps down and 90 Mbps up.
How does G.fast work?
Fibre runs from the network to a node in a pit, usually within a few hundred metres of your home. From there your existing copper phone line carries the signal the rest of the way. G.fast uses frequencies up to 212 MHz on that copper, far higher than VDSL2, which is what lets it reach near-gigabit speeds over short distances.
How fast is G.fast in Canberra?
Speed depends mostly on the length of copper between the node and your home, known as the drop length. These figures come from Infinite’s G.fast customers across 57 Canberra suburbs, published in our March 2026 sync speed update.
| Drop length | Average download | Average upload |
|---|---|---|
| 0 to 50 m | 935 Mbps | 103 Mbps |
| 51 to 100 m | 962 Mbps | 106 Mbps |
| 101 to 150 m | 766 Mbps | 103 Mbps |
| 151 to 200 m | 594 Mbps | 88 Mbps |
| 201 to 250 m | 421 Mbps | 65 Mbps |
| 251 to 300 m | 324 Mbps | 51 Mbps |
| 301 m and over | 297 Mbps | 48 Mbps |
Across the whole dataset the average was 694 Mbps down and 90 Mbps up, with a median of 665 Mbps down. 64.1% of connections synced above 500 Mbps and 98.3% above 250 Mbps. These are sync speeds for connections that achieved G.fast. Homes that could not get G.fast are not included.
Is G.fast part of the nbn?
No. The nbn is owned and operated by nbn co. G.fast in Canberra runs on the Vision Network, a separate wholesale network that began as TransACT. You buy it from a retail provider such as Infinite, just as you would with the nbn.
How does G.fast compare with the nbn?
Homes on nbn fibre to the node or fibre to the curb are limited to 100/40 Mbps on any plan, so G.fast is usually several times faster where both are available. nbn fibre to the premises and HFC now offer faster tiers. Where your home already has one of those, the two are closer and the choice comes down to plan, price and provider.
nbn co is upgrading parts of Canberra’s fibre-to-the-node footprint to full fibre over the coming years. If full fibre becomes available at your address, it is worth comparing the two again. Our guide to alternatives to the nbn in Canberra covers every option.
What equipment do I need?
Vision Network supplies a Zyxel GM4100 G.fast modem at installation. You only need your own router to share the connection around your home. G.fast on the Vision Network uses IPoE with DHCP, so your router does not need a username or password. Our support article explains how to set up your router for G.fast.
What if my line cannot reach G.fast speeds?
Sync speeds vary with cable length, cable quality and interference from things like solar inverters and poor internal wiring. If your line cannot reach faster than 250/50 Mbps, we will offer you a VDSL2 100/40 Mbps service instead. If you choose a 1000/100 Mbps plan and your line cannot reach it, you can move to one of our 250/50 Mbps plans.
How long does installation take?
Where the connection is available and the order is accepted, installation usually takes 2 to 4 working days. A Vision Network technician attends, connects the G.fast modem and tests the service.
Can my home get G.fast?
G.fast is available in many Canberra suburbs on the Vision Network footprint. Check your address on our Vision page or call our Canberra team on 1300 790 337.
