Looking for a cheap NBN plan? You've come to the right place. I make it my mission to seek out the cheapest NBN plans and the good news is, it's not actually that difficult. It's even easier to determine which plans offer the best overall value, and the good news once again is that there are now several internet service providers (ISPs) that offer an attractive service.
Whether you're searching for a popular NBN 50 plan or you need a much faster NBN 1000 plan there are affordable options to be found. What's more, since the introduction of the NBN speed upgrades in September 2025, I've seen some excellent value across NBN 500 plans in particular.
The good news is that the fastest NBN plans are becoming more and more affordable, with many costing less than plans 20 times slower. Of course, it’s also important to consider costs in the longer term. The cheap NBN plans I've recommended on this page are not only affordable when you first sign up, they also remain some of the most affordable options in the market after the initial discount has ended.
All of our plan recommendations are detailed below, but before you check them out, here are some good deals you should know about before deciding on an NBN plan:

Cheap NBN FAQ
Are cheap NBN 12 plans worth it?
In general, we don’t recommend signing up to an NBN 12 plan. Among the internet providers we monitor, the current average price of NBN 12 is AU$62.21 while the average cost of an NBN 25 plan is slightly more at just over AU$70. It’s a small increase for double the speed, so we don’t think cheap NBN 12 plans are worth it at all – you’re much better off with a cheap NBN 25 plan.
Here’s a look at some of the cheapest NBN 12 plans if you’re curious:
What is the cheapest NBN service?
The cheapest NBN service we’ve found comes from Flip, with an NBN 12 plan that starts at AU$39 a month for your first four months. While it’s the cheapest NBN plan available, it’s not one we would recommend, because we don’t recommend NBN 12 plans in general. Instead, if you want an NBN service that’s worth using, we suggest checking out Flip’s NBN 25 plan which also starts at AU$39 a month for your first six months, and gets you double the speed.
Are cheap NBN plans worth it?
Cheap NBN plans are worth it if saving money is your top priority, and there’s great deals to be had across all NBN speeds. However, before signing up to a cheap NBN plan, there are some aspects to consider:
How long the discount lasts:
Most NBN providers will offer you a discount for your first six months on the service – sometimes you can even get a cheaper rate for up to 12 months. Once the initial discount ends, consider whether the ongoing cost still makes it a cheap NBN plan. If not, you can always switch to another provider, which should be easy if you’re not locked into a contract or paying off any hardware.
Can you BYO modem:
Practically all NBN providers will ask if you’d like to include a modem with your new NBN plan, but if you already have one, you’ll save a good amount of money by reusing it whenever you switch telcos. You’ll likely need to reconfigure your modem to your new internet provider’s settings, but it’s pretty straightforward and the telco should give you instructions on how to do so.
What features are you missing out on:
A cheap NBN plan is often missing some of the more premium features of the major telcos, such as a modem with 4G backup or streaming add-ons. If you can do without these extras, you’ll likely spend less on your internet bill.
