Key points
- The three largest internet providers in Australia are Telstra, TPG Group (including TPG, Vodafone and iiNet) and Optus.
- While the big three still dominate, Aussies are increasingly moving towards smaller challenger providers such as Aussie Broadband and Superloop.
- You don’t need to go with the biggest internet providers to find a competitive broadband plan or the fastest speed.
When it comes to phone plan providers, we all know the ‘big three’ — Telstra, Optus and Vodafone — which happen to operate Australia’s only three mobile networks. However, if we’re looking at Australian internet providers, it’s a bit more complicated.
Now that the NBN (National Broadband Network) has been rolled out to most of the country, the landscape of the internet industry in Australia has changed. The NBN has broadened the competition with a ready-made network, ultimately giving consumers more choice in internet providers.
However, the internet market is still dominated by a handful of telcos. In this article, we’ll take a look at some of the biggest internet providers in the NBN market.

Who are the biggest internet providers in Australia?
With just over 38% of the NBN market share, Telstra (which also owns Belong) is the biggest internet company in Australia. Telstra also has the largest mobile network in the country, is listed on the S&P/ASX 20 index as a publicly-traded company, and is a household name when it comes to telecommunications.
The second biggest internet provider in Australia is TPG Telecom. TPG is already a well-known name when it comes to home internet plans in Australia, and is the parent company to several other well-known internet providers, including Vodafone and iiNet.
Optus is the third largest provider, followed by Vocus Group (Dodo and iPrimus). Challenger brands Aussie Broadband and Superloop are the fifth and sixth largest, respectively, with all other small telcos grouped together in seventh place.
To break it down, here are the largest internet providers — specifically for NBN — from the December 2024 quarter, as reported in the ACCC’s NBN Wholesale Market Indicators Report published March 2025. Providers are listed by percentage of market share.
- Telstra: 38.3% market share
- TPG Group (TPG, Vodafone, iiNet, Internode, etc): 20.0% market share
- Optus: 12.4% market share
- Vocus Group (Dodo, iPrimus): 8.8% market share
- Aussie Broadband: 7.8% market share
- Superloop: 6.1% market share
- Other providers: 6.7% market share

In comparison, the ACCC’s 2022 June quarter report listed Telstra’s market share at 43.3%, TPG at 23.1%, and Optus at 13.8%. The ongoing drop in market share for the bigger internet providers is largely due to a trend of Aussies switching to smaller and lesser-known brands — most notably, Aussie Broadband, Superloop and Southern Phone, according to the ACCC.
Are the biggest internet providers Australian-owned?
There is a lot of competition between NBN providers, but not all of these companies are owned and operated in Australia. Here’s which of the biggest telcos are actually Australian-owned.
- Telstra — partly Australian-owned
- TPG Telecom (TPG, Vodafone, iiNet, Internode, etc) — partly Australian-owned
- Optus — Singaporean-owned
- Dodo & iPrimus — Australian-owned
- Aussie Broadband — Australian-owned
- Superloop — Australian-owned

Do the biggest internet providers in Australia have the best internet deals?
Taking a look at the market share, it’s clear that a large number of Australian customers have chosen to sign up to only a small selection of NBN providers. Traditionally, Aussies have stuck to trusted names and big brands, making it easy for Telstra, Optus and TPG to stay dominant. However, with increased competition thanks to the NBN rollout, there’s a wider range of telcos to choose from, offering hundreds of plans to residential customers.
Finding the best internet deal doesn’t always mean you have to go with the most well-known and largest internet providers. Choosing a great NBN plan depends on what you want for your home internet. Price isn’t the only difference between NBN plans — contract length, included modems, and entertainment and bundle options can help determine which NBN plan is best for you. You might also choose your provider based on the NBN speed tier options available, and the typical performance during busy periods.
