Cheap NBN plans: quick menu

If you’re looking for a cheap NBN plan, there are plenty of great deals available across all NBN speeds, from the popular NBN 50 tier through to lightning-fast NBN 1000 plans. 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 despite a reduction to its introductory pricing offer, Flip still remains one of the cheapest providers in the market.

Cheap NBN 25 plan

A cheap NBN plan that doesn’t sacrifice speed

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

Best option for most users

Kogan Internet | 50Mbps | AU$62.90p/m
Best overall

Kogan Internet | 50Mbps | AU$62.90p/m (first 6 months, then AU$78.90p/m)

Kogan Internet has recently introduced a new pricing structure that makes it among the cheapest NBN plans across all tiers, but its 50Mbps NBN plan is particularly noteworthy. Its first-year cost is the cheapest of all providers we monitor, and it's ongoing cost is well below the current average of just over AU$1,010.

• AU$62.90 minimum cost
• AU$754.80 first year cost
• AU$946.80 ongoing yearly cost

A bump in speed for larger households

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

For super-fast internet, consider this

Spintel240Mbps AU$78p/m

Spintel | 240Mbps | AU$78p/m (first 6 months, then AU$89.95p/m)

Spintel’s NBN 250 plan reclaims its spot as the cheapest on this tier, again because of its ongoing cost. Dodo is cheaper by around AU$1, but if you want to look further ahead, Spintel is currently unrivalled. Even once the intro offer ends, Spintel’s standard pricing of AU$89.95 a month is the cheapest we can find in this speed tier.

• AU$78 minimum cost
• AU$1,007.80 first year cost
• AU$1,079.40 ongoing yearly cost

Cheap NBN 1000 plan

The fastest you can get, but only available in select locations

Buddy Telco | 875Mbps | AU$99p/m
Best for power users

Buddy Telco | 875Mbps | AU$99p/m

Buddy Telco's AU$99 flat fee is technically more expensive than Spintel in the first 6 months, but ongoing, it's less. The result is the cheapest NBN 1000 plan during each ongoing year (and only AU$40 more in the first 12 months). Plus, Buddy advertises much faster download speeds, and if you're opting for an NBN 1000 plan, you're likely going to want the fastest speeds possible.

• AU$99 minimum cost
• AU$1,188 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$60 a month for NBN 25 (first 6 months, then AU$75p/m)

TPG: AU$74.99 a month for NBN 12 (no discount) or AU$79.99 a month for NBN 25.

Among the three major telcos, TPG is the most affordable and generally offers the best 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 is best 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.
