October 6, 2026 It's a new month and that means there's always a good chance that NBN plan prices have changed. And in this instance, they have, particularly on higher-speed plans. Most notably, Spintel has dropped some incredible prices on NBN 750 (from AU$69/m) and NBN 1000 (from AU$76/m) plans.

If you're looking to save some money with a cheap NBN plan, then you're in luck, as there are some incredibly low prices available right now, especially on faster plans, such as Spintel NBN 1000 for AU$76/m first 6 months.

At the other end of the speed scale, Spintel also comes out on top, with its NBN 25 plan setting you back just AU$41/m for the first 6 months.

There are plenty of other excellent and cheap NBN plans to shop, and switching to a new provider is, in general, a relatively quick and easy process. Of course, nobody really wants to switch all the time, and so many of the cheapest internet plans I've found aren't just affordable in the first year of service, but from year two onwards too.

And, in a few isolated cases, I've picked a plan that isn't the absolute cheapest, but which I feel offers greater overall value. If you're not totally sold on any of my picks, you can click through to find a wider selection for whichever speed tier you're looking for.

Spintel | 25Mbps | AU$41p/m (first 6 months, then AU$69.95p/m)

Spintel's NBN 25 plan pricing has fluctuated in recent month, but appears to have now settled at AU$41p/m. That's great news, because it makes it the cheapest introductory cost for the tier, although not quite the cheapest provider in the first year, as the plan from Flip below proves. However, I still have to include Spintel here for anyone who wants to spend as little as possible for up to 6 months.

• AU$41 minimum cost
• AU$665.70 first year cost
• AU$839.40 ongoing yearly cost

Cheap NBN 50 plan

Kogan Internet Silver | 50Mbps | AU$69.90p/m (first 12 months, then AU$80.90p/m)

It might have the same introductory cost as its NBN 100/500 plans (which I'd ultimately recommend for that very reason), but Kogan Internet's NBN 50 is the cheapest over the first year thanks to a 12-month discount. What's more, it's the cheapest from year two onwards, and the only one to charge under AU$1,000, making this a great-value option.

• AU$69.90 minimum cost
• AU$838.80 first year cost
• AU$970.80 ongoing yearly cost

Cheap NBN 100 plan

Cheap NBN 500 plan

Kogan Internet Gold Plus | 500Mbps | AU$69.90p/m (first 12 months, then AU$85.90p/m)

If you're able to sign-up for an NBN 500 plan, then Kogan Internet, once again, simply has to be your first consideration due to its low first-year cost. As previously mentioned, it has the same first-year cost as both the NBN 50 and NBN 100 plans, helping to ensure it claims to the title as the cheapest NBN 500 plan.

• AU$69.90 minimum cost:
• AU$838.80 first year cost
• AU$1,030.80 ongoing yearly cost

Cheap NBN 750 plan

Spintel Home Turbofast | 750Mbps | AU$69p/m (first 6 months, then AU$94.95p/m)

Spintel has adjusted the price of its NBN 750 plan a few times recently, but has seemingly settled on AU$69p/m — the same as its NBN 500 plan. That makes it comfortably the cheapest NBN 750 plan available, and the only one to come in under AU$1,000 in the first year of service. What's more, the telco claims maximum plan speeds during the busy evening hours, giving you great bang for buck.

• AU$69 minimum cost
• AU$983.70 first year cost
• AU$1,139.40 ongoing yearly cost

• View more of the best NBN 750 plans

Cheap NBN 1000 plan

Belong Ultrafast | 875Mbps | AU$75p/m (first 6 months, then AU$110p/m)

Telstra's budget-focused brand, Belong, has slashed the introductory cost of its entire NBN plan lineup, and one of the most attractive options has to be the NBN 1000 plan. The AU$75/m intro is the most affordable of any provider right now, while the first-year cost is only slightly more than the Spintel plan below. You also get a free Belong SIM card loaded with AU$80 creddit, only adding to the value.

• AU$75 minimum cost
• AU$1,110 first year cost
• AU$$1,259.40 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$41 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.

September 1, 2026

Pinch and a punch! And I really did have to pinch myself this morning when I noticed there had been quite a bit of movement amongst the cheapest NBN plans on the market. There have been new additions to some tiers, such as Spintel returning to the NBN 500 tier, and price reductions of only AU$1, but that have a huge effect on which provider is the cheapest.

August 4, 2026

There hasn't been a whole lot of movement when it comes to the cheapest NBN plans. By this I mean the usual suspects are still present, such as Kogan Internet and Spintel. While that may seem like a bit of a bummer if you were hoping for some variety, the positive news is that the mentioned providers are still offering incredible discounts that are worth checking out.

July 3, 2026

The cheapest NBN plans are no longer as cheap. That's because NBN Co has increased wholesale costs as of July 1, and providers are starting to pass this cost onto consumers.

I've seen some price increases already, although fortunately not all plans are affected. I've found the cheapest options across all speed tiers below.

June 24, 2026

There hasn't been a huge amount of movement in the NBN space throughout June, although the biggest change has to be the arrival of some cheap NBN plans from TPG. More specifically, its NBN 100 and NBN 500 plans, that both now boast 12-month discounts and low introductory costs of AU$69.99p/m.

Elsewhere cheap plans from Optus, Origin and Vodafone remain.

May 6, 2026

There has been a fair amount of shake up when it comes to searching for a cheap NBN plan. Perhaps the biggest news is that Dodo has restructured its pricing. The telco was offering 12-month discounts, but that's now changed to 6 months. To help ease the pain, the telco has dropped the introductory cost on many of its plan by some margin, and it now lays claims to having the cheapest intro cost on the NBN 50 and NBN 750 tiers.

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.

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.
