Cheap NBN plans: quick menu

Whether you're searching for a cheap NBN plan or even the outright cheapest NBN plan on the speed tier that suits you the most, there are plenty of great options amongst the best NBN plans available across all speeds.

That's right, no matter if your home can run smoothly on a popular NBN 50 plan or it need a much faster NBN 1000 plan – or even the incoming 'hyperfast' NBN 2000 plans, there are cheap options if you know where to look.

The good news is that the fastest NBN plans are becoming more and more affordable, with many costing less than plans 20 times slower. We've also spotted at least one provider offering a full 12-month discount at the time of writing, making for incredible value. Elsewhere you'll find the more standard six-month discounts, with some prices fluctuating a little.

Of course, it’s also important to consider costs in the longer term. The cheap NBN plans we’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.

The most up-to-date pricing is now listed on this page, and now Spintel is seemingly among the cheapest providers in Australia, a title previously held for a long time by Flip.

Flip25MbpsAU$39p/m

Flip | 25Mbps | AU$39p/m (first 6 months, then AU$57.90p/m)

Flip continues to dominate as the cheapest NBN 25 plan provider, especially now it's received an exclusive WhistleOut discount that increases the introductory price period to 6 months (Flip only offers a 4-month discount directly). As a result, Flip's NBN 25 plan becomes even cheaper – less than AU$600 in the first year.

Total minimum cost: AU$39
First year cost: AU$581.40
Ongoing yearly cost: AU$694.80

Cheap NBN 50 plan

Dodo | 50Mbps | AU$68.90p/m
Cheapest overall

Dodo | 50Mbps | AU$68.90p/m (first 12 months, then AU$83.90p/m)

There's been a more fluctuation in pricing on the 50Mbps tier recently. Now that Buddy has ended its introductory discount, Dodo takes the crown for the cheapest NBN 50 plan, at least in the first year. The intro price of just under AU$70 can be beaten, but Dodo is offering a huge 12-month discount, making it unrivalled in the process. The ongoing yearly cost isn't as attractive, so we'd recommend switching to another provider such as Mate or Fliponce your first year is up..

• AU$68.90 minimum cost
• AU$826.80 first year cost
• AU$1,006.80 ongoing yearly cost

Cheap NBN 100 plan

Spintel | 100Mbps | AU$65p/m

Spintel | 100Mbps | AU$65p/m (first 6 months, then AU$81.95p/m)

Spintel gets our vote as the cheapest NBN 100 plan, particularly because its ongoing cost is the only one to come in under AU$1,000 of the providers we monitor. Spintel also regularly receives favourable reviews from customers and it advertises maximum plan speeds with this 100Mbps plan.

• AU$65 minimum cost
• AU$881.70 first year cost
• AU$983.40 ongoing yearly cost

Cheap NBN 250 plan

Spintel240Mbps AU$80p/m

Spintel | 240Mbps | AU$80p/m

Spintel’s NBN 250 plan maintains its spot as the cheapest on this tier thanks the removal of a previous introductory cost and replacing it with a low-cost flat-rate fee. In doing so, it makes Spintel's NBN 250 plan the only one to come in under AU$1,000 each year and is cheaper than some plans that are 10 times slower. Exceptional value.

• AU$80 minimum cost
• AU$960 yearly cost

Cheap NBN 1000 plan

Spintel | 750Mbps | AU$90p/m

Spintel | 750Mbps | AU$90p/m

As with its 250Mbps NBN plan, Spintel's NBN 1000 plan has also dropped the introductory discount in favour of a flat-rate charge that makes it unbeatable value. The telco's typical evening speed claim of 750Mbps isn't quite the fastest, but it's still respectable. Do note however, that we've seen Spintel now advertise this plan as NBN 750, indicating this is the maximum speed you can achieve.

• AU$90 minimum cost
• AU$1,080 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$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.

What are the cheapest NBN plans from the major telcos?

Telstra, Optus and TPG are more expensive than the budget internet providers, so their cheapest NBN plans may not be cheap compared to the likes of Flip, Spintel and Tangerine. Here is the most up-to-date pricing on the cheapest NBN plans from each major telco:

Telstra: AU$89 a month for NBN 25 (no discount)

Optus: AU$75 a month for NBN 25 (no discount)

TPG: AU$56.99 a month for NBN 25 (first 6 months, then AU$76.99p/m)

Among the three major telcos, TPG is the most affordable and generally offers the greatest value for money. As we noted in our TPG NBN review, the telco’s NBN 25 and NBN 50 plans are particularly good value as they offer the maximum download speeds available in each tier at a reasonable price.

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.
