What is the cheapest unlimited internet plan?
The cheapest unlimited internet plans will often come with slower speeds such as those on NBN 12 and NBN 25 speed tiers.
These likely won't meet the demands of households with 2 or more people who use the internet for work and entertainment.
Instead of focusing solely on the cheapest unlimited internet plan, we've highlighted the best budget-friendly options across all NBN speed tiers, 4G and 5G home wireless, and mobile broadband.
That way, you'll have a range of choices to suit your speed needs.

Is unlimited internet actually unlimited?
Yep, when an internet provider promises unlimited data, that's exactly what you get - no monthly limits.
You might see in the terms and conditions that a 'fair use policy' may apply. However, that's a pretty vague and subjective condition.
Unless you do something extreme, like running a speed test non-stop for 40 hours and using about 35TB of data - as one user did in 2020, which led Aussie Broadband to cancel their connection.
If you use the service in a way that's excessive or impacts others, you might face restrictions.
How do I find the best unlimited internet plan?
When you're looking for the perfect unlimited internet plan for your home, keep three things in mind: price, speed and provider.
Price
How much are you willing to pay each month? Finder research finds Aussies pay around $81 a month on average, though your budget might very well be different. What you actually end up paying will also depend on the speeds you're after. The good news is there's no shortage of sign-up deals floating around.
Speed
It all depends on your household and internet use. The more people and online activities you have, the faster your connection will need to be to keep everything running smoothly.
For example, NBN offers 8 main speed tiers, while home wireless broadband speeds typically cap at around 25Mbps on 4G. However, 5G home wireless broadband is much faster and more comparable to NBN speeds.
Most plans provide speeds between 50 and 100Mbps, but some providers, like Optus and SpinTel, offer faster or even uncapped options.
Mobile broadband speeds depend on your network and location, with 4G usually slower than NBN and 5G delivering much faster speeds.
Provider
It's a good idea to check out different options because not all providers are created equal.
Maybe you're after a provider that's strong on customer service and tech support, or maybe you only care that they actually deliver on promised speeds and offer a good price.
"I have an unlimited data NBN plan with Aussie Broadband and with 2 kids in the household it makes life easier that we don't have to monitor downloads. Especially with streaming and gaming big at our place, this can use hundreds of gigabytes each month. Having the internet slow down or cut off doing an important download or major binge session would be a disaster, so I'm very happy that we can avoid this."
Do I actually need unlimited home internet?
Home wireless and NBN data-capped plans are very rare these days so you'll almost always end up with unlimited home internet, even if your internet usage is limited.
In fact, only 2 out of 43 fixed-line NBN providers on Finder still offer data-capped plans.
Telstra is the only home wireless broadband provider in our database with a data-capped plan, but even that offers a solid 1TB (1000GB) of data.
With unlimited plans being the norm, they're no longer premium, and you can easily find budget-friendly options.
The caveat here is mobile broadband plans often come with data caps. If your data needs are low or you need portable internet while traveling, it might be a suitable option to consider.

SpinTel internet review
SpinTel offers simple and affordable internet plans. Find out if it's right for you in our in-depth review.
when fttp is installed do I need a modem or can I just use a router?
Hi Kev, you should just be able to use your router but it’s always best to double check with your internet provider for compatibility. Hope this helps!
I have recently paid over $5000 to have solar panels connected to my roof. I have also just found out that in order for my panels to feed electricity in to the grid, I need to have an internet connection. Apparently, this is a new rule. No one lives in this house on a permanent basis, so I do not need the internet, I do not want it, and I will never use it. I have to get it solely for my solar panels to work. Could you please advise me on the cheapest internet connection which I could find in Adelaide. Many thanks and cheers, Lisette
Hi Lisette, In this situation, you might want to look at mobile broadband plans – these use a SIM card rather than a wired connection. As you likely won’t need a large amount of data, this could meet your needs.
Hi i have NBN connected , does this give me access to my mobile usage, netflix and kato . What cost involved for this package
Hi Trevor, can I ask what NBN plan you’re on? You will be able to stream Netflix and Kayo if you have separate subscriptions for it already unless you’re with a providers that has these services included as part of your plan? As for your mobile, yes you will be able to use Wi-Fi to use your phone and run online activities.
Hi, I only have wireless connections at my home, so that has nothing to do with the NBN, does it? Excuse my ignorance. I want to get rid of my plan with Optus as I find it to expensive. So I was going to just get a cheap ph plan with probably Aldi but I want a reasonably priced internet plan alone. We don’t do a great deal on the internet, just Facebook, a bit of research but also need it for Netflix & YouTube. Any advice please.
Hi Wendie, yes home wireless is different to an NBN connection. You can use the following guide to find a home wireless internet plan that works best for your budget: https://www.finder.com.au/broadband-plans/home-wireless-broadband. Hope this helps!
