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.

If you're looking to save some money with a cheap NBN plan, then you're in luck. While wholesale costs may have increased recently, there are still plenty of affordable plans to be found, if you know where to look.

Fortunately, I do know where to look, and you'll find my top selections for cheap NBN plans below. 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?

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.

Cheap NBN 50 plan

Cheap NBN 100 plan

Kogan Internet Gold | 100Mbps | AU$69.90p/m (first 12 months, then AU$85.90p/m)

It was a tough choice to pick a cheap NBN 100 plan, as both Kogan Internet and TPG are offering 12-month discounts at the time of publishing. Kogan does come in cheaper though, and the telco receives far more positive reviews than TPG. However, TPG will provide a Wi-Fi 7 router if you need it, so it's still worth considering. For the outright cheapest though, look no further.

• 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$67p/m (first 6 months, then AU$94.95p/m)

I had to do a double take with this Spintel NBN 750 deal — it's so cheap! In fact, it's the only provider of those I monitor to come in under AU$1,000 in the first year, which is simply sensational. In fact, it's cheaper than Spintel's own, slower NBN 500 plan. That makes perfect economical sense to me.

• AU$67 minimum cost
• AU$971.70 first year cost
• AU$1,139.40 ongoing yearly cost

Cheap NBN 1000 plan

Superloop Lightspeed | 860Mbps | AU$84p/m (first 6 months, then AU$114p/m)

Now, this isn't the cheapest NBN 1000 plan you can find — especially now the price has increased slightly — but it is the one that I feel provides excellent value. Not only does Superloop extremely positive reviews from customers, and it's been found to overdeliver on its typical evening speed promises. So, if anything, you're likely to get more than you pay for.

• AU$84 minimum cost
• AU$1,198 first year cost
• AU$1,368 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.

Latest updates

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.
