Does Australia have an unlimited data plan?

There are two types of unlimited data plans available in Australia: If a provider offers a plan with no monthly data limit, expect a speed cap to be in place. This is as close as you'll get to a truly unlimited data mobile plan. If your plan includes a monthly data allowance and you exceed it before the next billing cycle, your speeds may be reduced to between 256Kbps and 2Mbps. Due to these caveats, providers often refer to it as 'endless data' or simply state 'no excess charges' in their plan advertising.

Is unlimited data worth it?

This comes down to how you use your mobile and how much data you tend to go through. It helps with peace of mind at the very least as you won't get hit with excess charges at any point. You can compare plans in our guide to see if any take your fancy.

How do excess mobile data charges work?

Excess mobile data charges apply when you use more data than your plan's limit. This usually happens on postpaid plans . Look out for SIM only plans with no excess charges. With this, your download speeds will slow down if you use up all your data allowance, but you'll never be charged extra.

Finder Score for mobile plans

We've scored over 300 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.

Read the full methodology

What's considered a high-data mobile plan?

There’s no magic number for ‘high-data’ plans, but we’d call anything over 40GB a solid choice. This is also the average amount of data Aussies get on their mobile plans, according to Finder’s Consumer Sentiment Tracker research.

Sure, gaming, video chats, and YouTube can eat up your data, but it’s Netflix and Stan that really take the cake, munching up to 3GB an hour.

So if you’re streaming on the go a lot, a high-data plan might a good option.

Is a high-data mobile plan right for me?

A high-data mobile plan is perfect if you’re all about streaming on the go or if your phone is your main gateway to the internet when you're out and about.

Pros

Ideal if you often use your mobile data outside of Wi-Fi zones, keeping you connected everywhere
Perfect for streaming video, gaming, and heavy browsing without worrying about running out of data
Most plans come with no lock-in contracts, so you can easily switch to a lower or higher data plan whenever you need
Frequent bonus data promotions mean you’ll get more data for less when you first sign up

Cons

If you don't use much data, you might be paying for more than you need
If your provider’s network coverage is spotty, you might not fully enjoy the perks of a high-data mobile plan.

Good to know: On average, Aussies use 13.85GB of data, so you might not need as much as you think. Always check your past usage before signing up for a plan. You shouldn't pay for data you're not using.

How much data is enough?

"I always overestimate how much data I need. I stream music and video on the go, so I always think I'll go through 50GB or 60GB a month, but I mostly use less than 20GB. However, when I work remotely I can't afford to be charged more or speed limited. My unlimited data plan from Felix has been great - it gives me the peace of mind of a high data plan, while saving money by being on the Vodafone network."

Tim Bennett

Insurance expert

What apps use the most data?

The biggest culprit for your need for a high-data mobile plan is video streaming. Streaming services like Netflix can eat up to 3GB an hour if you're streaming HD video. Other activities like taking video calls and social media can also dig into your monthly data allowance.

Activity	Data used
Netflix	3GB per hour with HD streaming
Facebook	Around 500MB per hour (depending on how much video content is on your feed)
Spotify	Up to 144MB per hour with very high quality playback
Youtube	2.5-4.GB per hour with HD streaming
TikTok	840MB per hour with default settings

If you're not up for paying for a higher data mobile plan, consider data-saving tips like downloading Netflix shows and Spotify playlists at home on Wi-Fi, so they don't eat into your mobile data.

Should I consider an unlimited data plan instead?

There's a good chance you want a high data mobile plan for peace of mind where you can avoid bill shock and still have access to your plan.

In that instance you could consider an unlimited data mobile plan. The catch being:

If a provider offers a plan with no monthly data limit, it probably comes with a speed cap. This is as close as you'll get to a truly unlimited data mobile plan. Only felix offers a plan like this one.
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 256kbps to 2Mbps.

Frequently asked questions

There are two types of unlimited data plans available in Australia:
1. If a provider offers a plan with no monthly data limit, expect a speed cap to be in place. This is as close as you'll get to a truly unlimited data mobile plan.
2. If your plan includes a monthly data allowance and you exceed it before the next billing cycle, your speeds may be reduced to between 256Kbps and 2Mbps.
Due to these caveats, providers often refer to it as 'endless data' or simply state 'no excess charges' in their plan advertising.

Finder

MariamJune 23, 2025Finder

Hi Jules, Telstra, Optus and Vodafone are the only ones that offer a phone on a plan. They’re all running end of financial year sales so check our their websites to see which phone takes your fancy. Otherwise, if you can tell me your budget / brand preference etc I can point you in the right direction. Hope this helps!

MariamJune 18, 2025Finder

Hi Juliana, you might be better off with a plan on the Telstra network as it offers the widest coverage. A mobile broadband plan might be a better option for you modem. You can compare plans here: https://www.finder.com.au/broadband-plans/mobile-broadband. It’s always best to double check network coverage on the provider’s website before signing up. Hope this helps!
