How we picked these
Finder Score for mobile plans
We've scored over 290+ mobile plans on everything from cost to data allowance and important features.
Our experts give each plan a score out of 10 - totally fair, with no commercial strings attached.
Key takeaways
- Unlimited data plans can help you avoid excess data charges. However, they almost always come with a catch.
- Plans either offer unlimited data with capped speeds or a set data allowance with slower speeds after it's used up. Both options help you avoid extra charges.
- We often don't use as much data as we pay for, so review your past usage or try a data calculator to choose the right plan.
What is unlimited data in Australia?
In Australia, an unlimited data plan means you won't face excess data charges or bill shock, so you can use as much data as you need without worrying about extra costs.
The caveat here is that all unlimited data mobile plans currently come with some sort of download speed cap.
That's why, from 2018 onwards, the Australian Competition and Consumer Commission ruled that mobile providers couldn't label their plans as 'unlimited' if they included any restrictions.
How does unlimited data work in Australia?
An unlimited data plan will work pretty much like your regular mobile plan.
There are 2 types of 'unlimited data plans' available in Australia:
- Unlimited data: 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.
- Endless data or no excess data charges. 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 and 2Mbps, depending on the plan.
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.
| Provider | Download speed cap |
|---|---|
| Telstra | 1.5Mbps |
| Optus | 1.5Mbps |
| Vodafone | 1.5-2Mbps |
| Aussie Broadband | 1.5Mbps |
| Belong | 1Mbps |
| felix | 40-80Mbps on its unlimited data plans, 1.5Mbps on all other plans |
| Dodo | 256Kbps |
| iPrimus | 256Kbps |
| JB Hi-Fi | 1.5Mbps |
How much does an unlimited mobile data plan cost?
The cost of an unlimited data mobile plan varies between providers.
felix is the only provider that comes close to offering truly unlimited data, with 2 plans available. The $40 monthly plan has a 40Mbps download speed cap, while the $50 plan doubles the speed cap to 80Mbps. Both prices exclude any discounts.
To put this in perspective, the average cost of prepaid plans in our database with no excess data charges is $52 a month, compared with $60 on postpaid plans.
The cheapest monthly option with no excess data charges is from Dodo, costing $25 a month for 25GB of data, excluding any promotions.
What is the best unlimited data mobile plan in Australia?
The best unlimited data mobile plan for you will depend on your own preferences, including network coverage, how much data you want, what speed caps you're okay with, and any other plan features you're after.
For example, felix could work best if you genuinely don't want any data caps at all and don't mind the speed caps of 40-80Mbps throughout.
For the other plans, it comes down to how you'd normally choose a mobile plan, with one key difference: what speed you'll get once you've used your included high-speed data allowance.
Do I need unlimited data?
An unlimited data mobile plan is great for avoiding excess charges, while capped plans can be effective if you monitor your data usage.
Check your past bills to gauge your data needs and choose accordingly.
You probably don't need as much data as you think.
The Australian Competition and Consumer Commission reports Aussies use 17.4GB postpaid and 9.3GB prepaid on average, yet Finder's survey shows we're paying for around 40GB.
If you're still unsure, use our mobile data usage calculator to figure out how much data you need and then sign up to a plan accordingly.
"I love the freedom of unlimited data, but I probably don't actually need it! Over the last 12 months I've used an average of 20GB or so per month, which is a little above the Aussie average of 12.8GB, but not by much. I think I got burned a bit too much by running out in the past. That said, my current plan, the felix $40 unlimited plan, is very reasonably priced, and it means I don't ever have to think about how much data I'm using."

Three.ie unlimited data and no throttling. While calls and texts are limited depending on plan, everyone uses data to communicate.
Ok Sorry but the reaaoning given by the 3 telcos is a load of nonsense. A modern city like HK with a third the population of Australia ALWAYS has unlimited data and plenty of call time in all their plans. There is NO difficult decision to make or justifiable reason why the telcos here can t offer unlimited data. The ONLY reason is pure GREED. Comparing the situation to the very scattered and poorly serviced US network smacks of a cover up. Your writers can do better than that.
Hello Nick,
Thank you for your inquiry.
We appreciate your sharing on this matter. Indeed many Australians are looking forward to that day when we can use unlimited data on our mobile phone plans. Just to clarify some points though, it is not the only US that uses “capping” on their unlimited offers. Many providers, including the ones in Australia, are doing that in compliance with the Fair Usage Policy (FUP), which will ensure equal distribution of network resources to all customers.
While no signs can be seen yet if Australian providers will give this, your options will be to use home/office wifi, use public wifi, if you’re a Telstra fixed broadband customer you can use Telstra Air, pre-load your content if you’re watching videos, or use mobile broadband device.
Hope this helps.
Cheers,
Jonathan
What about Vivid Wireless?
They have an Unlimited Internet Plan for $89 per month.
Vividwireless LTE internet service provides up to 10mbps download and 1 mbps upload.
Hi Steven,
Thank you for getting in touch.
The technology of Vividwireless is purpose built for data rather than mobile phone services, which means they do not include call or text services. They would fall under the mobile broadband category instead.
Kind regards,
Jason
I’m on 2dollars a day plan with Optus pre-paid it’s unlimited everything for 2buks a day. The catch is if use ur credit it will charge 2 dollars but only 2dollars for that day. I don’t know if they still have this plan. Since I’ve had it for years now no doubt the best pre-paid plan Iv found all up 60 bucks a month but has unlimited internet. I use my hotspot all day and it only charges me 2 dollars. I don’t know Wat ur on about for not having unlimited in Australia
Yes i am on the Optus $2 a day 3G ready plan. Had it for years and still loving it. I use it for personal hotspots and letting my friends go crazy on it. I use up to 30-50 gigs a month. Imagine the cost in comparison to today’s plans?
Hi there,
Thanks for your comment.
Yes, as of this writing, Optus is still having the $2 Prepaid product with 4G Coverage, however, the data allowance included is only at 500MB (counted in 1KB increments) for use within Australia with 7-day expiry. Please note though that this offer and plan may change in the future.
Most networks nowadays are generally not having unlimited data on their mobile data plans due to the huge number of mobile data users, which in turn could impair providers economically. Companies find that improving the data speed is costly to maintain. Although the data is not unlimited, most of these companies have dropped the outright data pricing and one example for that is the $2 Prepaid from Optus.
Cheers,
May
