Cheap NBN plans: Compare speed tiers and providers

Finding cheap NBN plans doesn't have to involve hours of research. We can help you quickly compare the cheapest plans from among the 30+ providers in our database, using our handy tables below. Our data experts update our plans regularly, so you'll always be looking at the latest list of the cheapest NBN plans we track, including any special deals going right now.

We've ranked these plans based on the total cost over the first 12 months after signing up (including new customer discounts). This helps account for intro offers, but also gives you a better idea of longer term costs. Unfortunately, projecting pricing out further than 12 months isn't as useful because NBN plans tend to go up in price every year in July by an unpredictable amount.

Monthly price: $47 for the first 12 months, $59 per month after intro deal ends
Annual cost: $564 for the first year, $708 per year thereafter

Currently, the cheapest NBN 25 plan in our database comes from Southern Phone. The nbn Basic plan normally costs $59 per month, but is reduced to a $47 monthly fee for the first 12 months after signing up. This deal is available to new customers as who sign up before February 10, 2026. Even once the discount period ends, the ongoing price is still competitive and comes with 25Mbps typical evening download speeds and 8Mbps upload speeds – the latter is worth noting if you use any kind of cloud storage, given many NBN 25 plans max out at under 5Mbps.

If you sign up and it’s not for you, Flip also offers a 14-day satisfaction guarantee and has no lock-in contact, so you can get your money back and find another cheap NBN plan that might suit you better. For comparison, check out more of the cheapest NBN 25 plans from our database below.

Monthly price: $65 for the first twelve months, $79 after intro deal ends
Annual cost: $780 for the first year, $948 per year thereafter

Southern Phone currently has the cheapest NBN 50 plan in our database. This plan has a $14 discount for the first twelve months for new customers, after which the ongoing cost is $89 per month – offer available till February 10, 2026. While this deal is great due to its length, it's worth noting the standard pricing is a bit more than you can get from other providers. This is largely offset by the the full first year being $14 off, but keep in mind you can switch to a cheaper provider once this intro discount expires.

If this plan isn't for you, you can compare Southern Phone with other cheap NBN plans from our comparison engine below.

Monthly price: $75 for the first twelve months, $900 after intro deal ends
Annual cost: $929.64 for the first year, $1,068 per year thereafter

For NBN 100, Southern Phone has our database's cheapest plan right now with its Home Fast 100/20 plan. Normally priced at $89 per month, new Southern Phone customers pay $75 per month for the first six months.

But it's worth noting this plan is only a tad ahead of plans from some other providers over that first twelve month period, which you can check out below. That, and Southern Phone's post-deal pricing is a tad above the standard pricing of some other providers. So while the first year is the cheapest, the gap will close with time.

Alternatively, consider one of these other cheap NBN 100 plans from our database:

Monthly price: 64 per month for first six months, then $84.95 per month after intro deal ends
Annual cost: $893.64 for the first year, $1,019.40 per year thereafter

Spintel's Home Turbo 500/50 NBN plan is discounted $20.95 per month for the first six months after signing up, via an exclusive deal for new customers you can access in the widget above. On top of this, the the normal price is $84.95 per month – which is itself pretty cheap.

Spintel is also one of the few telcos that can already report Typical Evening Speeds for its new NBN 500 plan, so you can get a decent idea of what to expect before you sign up.

If this plan isn't for you, check out other cheap NBN plans in our comparison table below.

Monthly price: $74 per month for first 8 months then $89.90 after intro deal ends
Annual cost: $951.60 for the first year, $1,078.80 per year thereafter

Flip's Unlimited Super Speed nbn750 plan is discounted $15.90 per month for the first eight months after signing up. And the standard price is $89.90 per month, which is still quite competitive.

Flip reports the full 750Mbps typical download speeds during peak periods, and a fairly standard 42Mbps for uploads. Just remember that NBN 750 plans are only available to FTTP (Fibre-to-the-Premises) and HFC (Hybrid-Fibre Coaxial) premises.

If this plan isn't for you, check out other cheap NBN plans in our comparison table below.

Monthly price: $85 for the twelve six months (new customers only), $95 after intro deal ends
Annual cost: $1,020 for the first year, $1,140 per year thereafter

The category of NBN 1000 plans is getting a bit murky, thanks to the introduction NBN 750 plans, which raises a few considerations:

• Some NBN 750 plans can be as fast or faster than the slowest NBN 1000 ones
• The fastest NBN 1000 plans tend to sit between 850Mbps and 900Mbps – which isn't as much faster than NBN 750 as you might have assumed
• You mightn't even need NBN 1000 to begin with. 750Mbps might do you fine and there's no point paying for speed you won't need
• Uploads might matter to you. NBN 1000 plans have double the maximum downloads of NBN 750 (100Mbps vs. 50Mbps). This is one of the main reasons you might consider NBN 1000 over NBN 750

But, if you do need NBN 1000, then Southern Phone currently has the cheapest plan in our database. In fact, it's cheaper than a lot of NBN 750 plans over the first 12 months after signing up, though its post-discount pricing is around $5 to $10 more than the cheapest NBN 750 plans. Southern Phone's NBN 1000 deal price is $85 per month for the first 12 months (for new customers), while the standard pricing is $95 per month.

Unfortunately, Southern Phone doesn't have Typical Evening Speeds for this plan yet, so it's tough to get an idea of what kind of performance you might expect before signing up. But the plan has no contract, so you can always switch away if it's not up to par.

Note, your premises needs an FTTP or HFC NBN connection to sign up for an NBN 1000 plan. If that’s you, below is a list of the cheapest NBN 1000 plans from our database, so you can check out a few more options:

Monthly price: $85 for the first six months (new customers only), $109 after intro deal ends
Annual cost: $929.64 for the first year, $1043.40 per year thereafter
Special restrictions: FTTP only

NBN 2000 is the new fastest speed tier available for home NBN plans. And while this speed tier is limited to FTTP and HFC connections, some providers are choosing to restrict that further to only FTTP.

One such provider is Southern Phone, which currently has the cheapest NBN 2000 plan in our database, though this time it's not because of an introductory discount – the telco's standard pricing is just that much cheaper. At $149 per month, it's $15 or more cheaper than the standard pricing of other providers. It's even cheaper than the intro offers of some of the competition.

If you'd like to check out other NBN 2000 plans (such as if you have an HFC connection), below is a list of the cheapest options in our database:

Many, perhaps most NBN plans have special introductory discounts, after which the monthly cost increases to an "ongoing" price. These discounts usually last six months and are for new customers only, but can be longer or shorter and sometimes embrace returning customers.

This might sound like a gotcha, but it can actually be good news. Changing NBN providers is easy, with little red tape and (usually) no noticeable gap in service. This means you can change providers regularly to maintain a healthy discount, without ever paying full price. It's a great way to save money, and has been officially advised by the Australian Competition and Consumer Commission (ACCC).

As such, where an NBN deal like this lasts for six months or more, we display it as the main price of the plan in our tables. But we include a green "Deal" disclaimer, which you can click on to view additional pricing and timeframe information. You can also click on "View Full Results" at the bottom of any table, then change the Sort option to "Avg. Monthly Cost" to see the average price over the first 12 months after signing up (deal pricing included). Given most NBN plans increase in price every July, a longer-term comparison than this isn't necessarily useful.

One of the most important things to consider when looking for a cheap NBN plan is to  work out which NBN speed tier you need. An NBN 12 plan's price might look appealing, but if you are a household of heavy internet users, you'll experience slow internet speeds that won't keep up with your needs.

Also, double-check whether the price you're getting is a promotional discounted price for new customers. If so, you'll need to check what the original price will revert to once the promotion is finished. If you're not in a contract - and most NBN plans aren't - you can easily find another cheaper plan to swap to.

​Still, when shopping for a budget broadband plan, there are a few things to keep an eye out for:

• Technology at your address: If you're looking for a faster plan, NBN 250 and 1000 are only available to select FTTP and HFC customers. Knowing what NBN technology you have available at your address is the first step to knowing what deals are available to you.
• Promo pricing: Though most telcos no longer offer contracts, they do offer limited-time promotional pricing (typically for the first six months of your plan). When shopping for the cheapest NBN plans, be sure to check what the monthly price will be after your first six months.
• BYO modem: Most smaller providers offer BYO modem broadband plans and won't necessarily supply a modem unless you specifically request it. You will also incur an outright fee for the modem on your first bill if you do choose to take a modem. If you do already have an NBN modem that you're happy with, be sure to let your provider know you would like to BYO.

There's one notable way to access free home internet in Australia. The School Student Broadband Initiative (SSBI) is a government-backed program through which families with school-aged children can apply for free NBN internet.

There are 30,000 spots available. Applications can still be placed until all places have been filled, though they aren't guaranteed to continue being accepted after 2025. Successful families will receive free internet until 30 June, 2028.
