Just a decade ago, ADSL technology was the speediest way to access the internet at home, but since then it has been superseded by the ultra-fast fibre of the National Broadband Network (NBN). But what was ADSL and is it still available in Australia today? Canstar Blue explores ADSL vs the NBN.
On this page:
What is ADSL?
Asymmetric Digital Subscriber Line, or ADSL, was a form of broadband connection that used the copper wires of the old telecommunications network to deliver internet into homes at speeds faster than original dial-up internet.
The technology was first introduced into Australia in the early 2000s, and offered download speeds around 256Kbps (kilobits per second), compared to dial-up’s approx 50Kbps. Over the next decade, the technology developed through ADSL2 to ADSL2+, which offered speeds of around 24Mbps (megabits per second).
What is NBN?
The NBN is a nationwide infrastructure network that provides households with access to the internet. It uses a mix of technologies, including fibre-optic cables, fixed wireless and satellites, that can deliver internet at far faster speeds than were available via ADSL.
NBN plans are available at the majority of Australian addresses, with dozens of providers now selling NBN to customers. You can see a selection of plans in the table below.

Is NBN faster than ADSL?
As we mentioned above, the quickest ADSL plan, ADSL2+, offered speeds of around 24Mbps. In comparison, all but the NBN’s two Home Basic plans offer far higher data speeds.
Depending on your location, NBN connection type, and choice of provider, you’ll be able to pick from the following speed tiers:
| Speed tier | Also known as | Maximum download speed |
|---|---|---|
| NBN 12 | Home Basic I | 12Mbps |
| NBN 25 | Home Basic II | 25Mbps |
| NBN 50 | Home Standard | 50Mbps |
| NBN 100 | Home Fast | 100Mbps |
| NBN 250 | Home Superfast | 250Mbps |
| NBN 1000 | Home Ultrafast | 1000Mbps |
Is ADSL still available in Australia?
As the NBN was rolled out across the country, the old copper telecommunications networks it replaced were disestablished, making ADSL a redundant technology. As a result, telcos no longer retail new ADSL plans to consumers, although a handful of customers without NBN access may still be on older ADSL plans where the network is still available.
What are my options if I can’t get NBN?
Most Aussies will now have access to an NBN connection, but the type of technology available will depend on your location. The majority of households and businesses can connect via fibre, but addresses in regional areas may be limited to either fixed wireless NBN or SkyMuster (NBN Co’s satellite service).
If you don’t have a reliable or available NBN connection, or want an NBN alternative, you may have access to other home internet solutions, including:
- Home wireless broadband: A fixed wireless internet connection that uses the same 4G or 5G mobile network as your phone.
- Mobile broadband: Similar to home wireless broadband, but is designed for portable use.
- Private fibre networks: Fibre internet networks owned and operated by private companies that are available in selected areas. These networks offer similar speeds and performance to NBN Co. Notable brands include Gigacomm, Opticomm and Uniti.
- Starlink: SpaceX’s Starlink satellite internet is now available Australia-wide and is a fast alternative to NBN SkyMuster or fixed wireless in rural areas.
