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 12.8GB 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."

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.

ActivityData used
Netflix3GB per hour with HD streaming
FacebookAround 500MB per hour (depending on how much video content is on your feed)
SpotifyUp to 144MB per hour with very high quality playback
Youtube2.5-4.GB per hour with HD streaming
TikTok840MB 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:

  1. 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.
  2. 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.

      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!
