How much should I be spending on broadband?
The average cost of broadband as per our Consumer Sentiment Tracker is between $79 and $104 a month for NBN (depending on the speed), about $81 a month for home wireless broadband and $67 a month for mobile broadband. If you’re paying more than this, it might be worth switching or at least comparing your options.
How do you choose the cheapest internet plan?
While saving money is important, it’s just as crucial to find a plan that suits both your budget and your household’s needs.
There’s little point in scoring a cheap deal if you end up stuck with a painfully slow connection.
Here are 4 key things to consider when looking for a cheap internet plan:
Which connection type works best for you?
Fixed-line NBN is the standard in Australia, but if you have strong mobile coverage where you live, home wireless could be a viable alternative for similar speeds. Especially if you're unhappy with your NBN connection. It runs on the same mobile networks as your phone, offers similar speeds, doesn’t need a technician to install, and can sometimes be cheaper depending on the provider. If you're after internet on the go or only need the basics, a mobile broadband plan could be a handy and flexible option.
How much data do you need?
These days, there’s no point considering a data-capped broadband plan unless you’re going with mobile broadband. The majority of NBN and home wireless internet plans come with unlimited data for roughly the same price - and with more choice. You’ll also have peace of mind instead of stressing about hitting your data cap too early in the month.
Which internet speed should you get?
The NBN offers 8 different speed tiers. The faster the speed, the higher the cost, so pick based on how many people are using the connection and what for. With home wireless and mobile broadband, you'll typically pick between 4G or 5G depending on your budget and how strong the mobile signal is in your area.
Can you bring your own modem?
With NBN plans, many providers let you bring your own modem to save on upfront costs, as long as it’s compatible. Home wireless doesn’t support BYO. You’ll need to use the modem supplied by the provider, which is often free or available for a small rental fee if returned later. Mobile broadband doesn’t require a modem, you'll need to insert the SIM in like a dongle, tablet or hotspot.
With these in mind, you're ready to compare plans to find a better deal for your internet at home. You can use the filters on our comparison table to sort by lowest to highest price to find a cheap broadband plan that works for you.
"I'd love to say I'm someone that compares and switches every year but until recently, that wasn't true. I've always thought it would be really complicated (I work in insurance, where sometimes switching is less than easy). It was incredibly straightforward and fairly cheap. I'll be comparing and looking to switch every year now."

I like using my mobile net for internet and calls currently I am paying $25 / month for 40GB but the data seem to run out quick . Can you tell what be best for me.
i love browsing and sports and Netflix ??
Hi Komini, you can check out high data mobile plans here and pick one that best fits your budget: https://www.finder.com.au/mobile-plans/high-data-sim-only-mobile-plans. Hope this helps!
what is the difference between mobile broadband internet, wireless internet, and wi-fi broadband?
Hi Huey, 4G and 5G wireless home broadband plans use phone mobile networks to supply an Internet connection, rather than relying on a wired connection, which is what the NBN does. Wi-Fi is the technology which allows your computer or tablet or smart TV to connect to your Internet service without needing to have a cable connected. This means you can use devices anywhere in your home, but the speeds aren’t quite as good as if you did connect via a cable. Wi-Fi can be used whether you have NBN or 4G/5G for your Internet plan. Hope this helps!
I am wanting a small mobile data plan (10gb-20gb) that does not time expire, in otherwords just consume the data. This is for NBN backup which is super reliable but does have outages. In a residential situation it is a complete waste of money to buy a 365 day plan for $100+ and 200gb+ which will be rarely used.
I cannot find any provider offering such product. Any advice>
Regards
Barry
Hi Barry,
As you’ve pointed out, most of the long expiry data only mobile broadband plans cost over $100 and you get 80GB or more of data.
The cheapest 365 day mobile data only plan in Finder’s database at the time of writing is from Aldi, which offers 30GB of data for $95.
If you consider that too much data for you, then other plans that offer smaller amounts of data are monthly plans, which may not suit your needs.
You can read more about mobile broadband in our guide to see if you can find something suitable: https://www.finder.com.au/broadband-plans/mobile-broadband
Hope this helps.
