What is unlimited data in Australia?
An unlimited data mobile plan in Australia helps you avoid getting hit by excess charges. However, these plans will come with some form of speed cap.
That's why back in 2018, the Australian Competition and Consumer Commission ruled that mobile providers couldn't call their plans "unlimited", because they always came with a catch and were at the time being falsely advertised.
How does unlimited data work in Australia?
An unlimited data plan will work pretty much like your regular mobile plan but with a couple of differences.
There are 2 types of unlimited data plans available in Australia:
If a provider has no monthly data limit on its plan, there's likely going to be a speed cap in place throughout. This is the closest you'll get to a truly unlimited data mobile plan.
If the plan comes with a monthly data allowance and you use it up before your next billing cycle, your speeds could be slowed down to anywhere between 1 to 10Mbps.
The main thing is you won't be hit by excess data charges on any of these plans, which can help you avoid bill shock.

felix is currently the only mobile provider in Australia that comes close to offering a truly unlimited data plan in Australia. That's why it easily won Finder's 2023 Best Prepaid Mobile Provider - High Data award.
felix originally came out with a singular plan - unlimited data but capped at 20Mbps at all times.
Last month, it released new plans in a more similar style to the bigger telcos. You have the choice between 25GB or 50GB of monthly data, with no excess data charges if your surpass this limit.
Signing up with felix means you'll:
Get access to Vodafone's 4G network
Be signed up to a carbon neutral plan
Have a tree planted on your behalf each month your subscription remains active
Good to know. 20Mbps isn't as slow as it might sound. For example, Netflix recommends at least 3Mbps for high definition quality, 5Mbps for full high definition and 15Mbps for ultra high definition.
