March 24, 2026 Just over two weeks since I last updated this guide focusing on my favourite cheap NBN plans, Kogan Internet has once again adjusted its pricing. It's still good news, as the telco remains the cheapest provider on the NBN 100 and NBN 500 tiers, but the introductory cost for both has risen by a whole AU$2. You can find the latest prices further down.

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 across all speed tiers. Not only do I look at the first-year cost of each plan, but I look at the ongoing cost too — while it might be relatively easy to switch providers on a regular basis, nobody really wants to do that all the time, do they?

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.

Cheap NBN 50 plan

Cheap NBN 100 plan

Kogan Internet Gold | 100Mbps | AU$71.90p/m (first 12 months, then AU$85.90p/m)

As mentioned earlier, Kogan Internet has recently increased the introductory price of its NBN 100 plan by AU$2, but combined with a 12-month discount, it continues to be the cheapest provider for this speed tier. Plus, the ongoing cost from year two is also the cheapest, making this the go-to option in my opinion.

• AU$71.90 minimum cost:
• AU$862.80 first year cost
• AU$1,030.80 ongoing yearly cost

Cheap NBN 500 plan

Kogan Internet Gold Plus | 500Mbps | AU$71.90p/m (first 12 months, then AU$85.90p/m)

Given the fact NBN 500 plan prices are, on the whole, the same as their 100Mbps equivalents, the top cheap NBN 500 plans are from Kogan and Dodo once more. If you want the cheapest NBN 500 plan, look no further than Kogan Internet. Both the introductory monthly cost over the first 12 months and the ongoing cost from year two, are both the outright cheapest and well below the current average. Plus, the telco receives generally favourable reviews from customers.

• AU$71.90 minimum cost:
• AU$862.80 first year cost

Cheap NBN 750 plan

Also condier

Superloop Megaspeed | 750Mbps | AU$74p/m (first 6months, then AU$104p/m)

Yes, it's more expensive than the Dodo plan above, but Superloop's Megaspeed NBN 750 plan claims maximum plan speeds, and is the cheapest telco to do so. That being said, its gigabit plan further down isn't much more expensive, and I'd argue the extra 250Mbps in speed is worth it. Still, if you're after an NBN 750 plan, this is a good one to check out.

• AU$74 minimum cost
• AU$1,068 first year cost
• AU$1,248 ongoing yearly cost

Cheap NBN 1000 plan

Superloop Lightspeed | 860Mbps | AU$79p/m (first 6months, then AU$109p/m)

The cheap price on this NBN 1000 plan is frankly incredible and one I seriously recommend you take advantage of if you've been craving fast download speeds at home. Superloop is currently hosting a 'Speed Sale', which has seen the introductory cost of its gigabit plan drop to just AU$79p/m (from AU$84), which is remarkable value.

• AU$79 minimum cost
• AU$1,128 first year cost
• AU$1,308 ongoing yearly cost

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$72. 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 I've found comes from Spintel, with an NBN 25 plan that starts at AU$39 a month for your first six months.

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.

March 2, 2026

There's been yet more movement in the NBN space. Following some price drops from Kogan Internet, the telco has dropped them even further, resulting in some insanely low prices, particularly on the NBN 100 and NBN 500 tiers.

February 17, 2026

Following the surprise 'Speed Sale' event from Superloop that popped up last week (and which is still going strong), Kogan Internet has now dropped the introductory monthly price of its NBN 100 and NBN 500 plans by AU$3. That might not sound like much, but it's resulted in the telco now being the cheapest in the first year for either plan – if you've been considering an NBN 500 plan then, Kogan Internet could be your best option.
