Best unlimited NBN plans: our expert picks based on speed, price and service

Buddy Telco | AU$65p/m

Buddy's NBN 25 plan advertises 24Mbps during the typical evening hours, which is on par with its parent company, Aussie Broadband. You'll save around AU$5p/m compared to the average price of this tier, which is currently AU$70.21p/m.

And of course, like the other plans featured on this hub, you'll score unlimited data, so you'll never have to worry about exceeding your caps wh scrolling on socials.

Total minimum cost: AU$65 | Yearly cost: AU$780

Flip | AU$39p/m (for 4 months, then AU$57.90p/m)

The best unlimited NBN 25 plan in our opinion is this one from Flip. Not only does it offer unlimited monthly data usage, but it's also the cheapest NBN plan to claim the maximum 25Mbps download speeds during the busier evening hours of 7pm to 11pm, coming in at under AU$585 for the first 12 months.

Online reviews also paint a relatively positive picture for Flip, so it's certainly well worth considering if you're looking for an affordable 25Mbps NBN plan.

Total minimum cost: AU$39 | Total cost for first 12 months: AU$619.20 | Yearly cost after discount: AU$694.80

Spintel | AU$47p/m (for 6 months, then AU$59.95p/m)

Offering an AU$10.95p/m saving for the first six months, Spintel’s Entry 25 is one of the most affordable unlimited NBN plans available right now.

Reaching maximum advertised speeds of 25Mbps during the typical evening hours, this plan could be a great option if you want to maximise savings. And with no lock-in contract, you can change providers if you find your service isn’t up to scratch.

Total minimum cost: AU$47 | Total cost for first 12 months: AU$641.70 | Yearly cost after discount: AU$719.40

Buddy Telco | AU$65p/m (for 6 months, then AU$75p/m)

Advertising 49Mbps downloads and 16Mbps uploads, this NBN 50 plan slashes AU$10p/m off for the first six months — that's AU$60 total, before the price increases to AU$75p/m. Buddy's plan does come with a small speed discrepancy, but it is so minimal it will unlikely make much of a difference to the service.

Total minimum cost: AU$65 | Total first year cost: AU$840 | Yearly cost after discount: AU$900

Kogan | AU$58.90p/m (for 3 months, then AU$68.90p/m)

Kogan’s Silver Unlimited NBN 50 clocks in with evening speeds of 50Mbps and 17Mbps uploads. Thanks to this initial discount offer, you'll save AU$10p/m over the first three months — that's AU$30 — before the price increases.

Kogan offers new customers an Internet Price Pledge, so if you find a better price on the same NBN plan, the telco will give you back double the difference.

Do note though, that this initial outlay is only available for the first 3 months, not the first six months like we see for most other providers.

Total minimum cost: AU$58.90 | Total cost for first 12 months: AU$796.80 | Yearly cost after discount: AU$826.80

Flip | AU$64p/m (for 4 months, then AU$73.90p/m)

Flip offers one of the most affordable 50Mbps NBN plans with unlimited data. Typical evening speeds are advertised as the maximum 50Mbps and, as is the case for the vast majority of internet service providers (ISPs) there's no lock-in contract, so you are free to leave whenever you wish — just make sure you read the cancellation terms and conditions!

Total minimum cost: AU$64 | Total cost for first 12 months: AU$847.20 | Yearly cost after discount: AU$886.80

Tangerine | AU$62.90p/m (for 6 months, then AU$82.90p/m)

Tangerine also offers one of the more affordable NBN 50 plans, whilst also offering the full 50Mbps download speed. Beating out Flip by offering AU$120 in savings, Tangerine makes this list thanks to its 14-day free trial which means you can try the service before you buy.

Do note that Tangerine isn’t the cheapest when it comes to purchasing a required modem, although with the rather excellent Amazon eero6+ router offered as the default option, we think it's worth the investment.

Total minimum cost: AU$62.90 | Total cost for first 12 months: AU$874.80 | Yearly cost after discount: AU$994.80

Spintel | AU$65p/m (for 6 months, then AU$81.95p/m)

Spintel's NBN 100 plan offers sensational value for a low cost and now comes with a superb AU$16.95p/m discount for the first six months. Across all NBN 100 plans, the offering has the lowest first yearly price of a modest AU$881.70 and one of the cheapest ongoing costs after the introductory discount ends.

There’s little in the way of extra features with this plan – which will likely go some way to explaining the low cost – but if you’re just searching for a no-frills NBN plan to get you connected, Spintel is well worth your attention.

Total minimum cost: AU$65 | Total first year cost: AU$881.70 | Yearly cost after discount: AU$983.40

Buddy Telco | AU$85p/m

Buddy's Speedy NBN 100 plan promises to reach 98Mbps download speeds during busy evening hours. It does come with a speed caveat, but it will not likely make much of a noticeable real-world difference. With that in mind, you'll save AU$60 in your first year and have a relatively low ongoing cost for an NBN 100 plan with unlimited data, so it's a clear winner to us.

Total minimum cost: AU$85 | Yearly cost: AU$1,020

Dodo | AU$68.90p/m (for 12 months, then AU$88.90p/m)

Serving up exceptional value is Dodo's NBN 100 plan. Thanks to a current WhistleOut exclusive discount, which saves a massive AU$20p/m for the first year — that's AU$240 total — it's one of the most affordable NBN 100 plans in Australia.

Best of all, Dodo advertises the full 100Mbps download speed during the busier evening hours and you get unlimited data, which is pretty neat.

Total minimum cost: AU$64.80 | Total cost for first 12 months: $826.80 | Yearly cost after discount: AU$1,066.80

Spintel | AU$78p/m (for 6 months, then AU$89.95p/m)

If you can access the NBN 250 speed tier but are more concerned about spending as little as possible, then this plan from Spintel is our top pick. Advertising 235Mbps during the peak evening hours, this Spintel deal slashes AU$71.70 off over the first six months—before the price increases to AU$89.95.

The telco has also received some great reviews online, with customers praising the easy installation and friendly support representatives. You can also bundle a phone line or mobile plan with this offering, starting from AU$10p/m.

Do note though, that this plan is only available for FTTP and HFC addresses.

Total minimum cost: AU$79 | Total cost of first 12 months: AU$965.70 | Yearly cost after discount: AU$1,031.40

Superloop | AU$85p/m (for 6 months, then AU$99p/m)

The best unlimited NBN 250 plan in our opinion right now comes from Superloop. While the telco doesn’t advertise the fastest typical evening speeds on the NBN 250 speed tier, coming in at an Optus-matching 240Mbps, it is the cheapest provider offering the fastest speed. We’ve also chosen it as our best overall plan because the telco offers customers the ability to boost their speed to the next tier up — NBN 1000 — five times a month. Superloop currently advertises typical evening speeds of 811Mbps on this speed tier.

If you don’t use all five Speed Boost days in one month, you can have them rollover into the next. You’re able to bank a total of 30 days.

Total minimum cost: AU$85 | Total cost for first 12 months: AU$1,104| Yearly cost after discount: AU$1,188

Buddy Telco | AU$99p/m

Buddy Telco’s Zoomy NBN 1000 plan advertises an impressive 875Mbps downloads and 41Mbps uploads during the busy evening hours of 7pm to 11pm. Do note though, that this plan is available for HFC and FTTP addresses only. Despite having slower speeds than some other providers on this tier, the plan has a yearly cost of just AU$1,188, which makes it the cheapest NBN 1000 plan right now.

If you need faster speeds, you could consider Superloop's NBN 1000 option for a similar ongoing pricepoint and 811Mbps advertised speeds.

Total minimum cost: AU$99 | Yearly cost: AU$1,188

Superloop | AU$99p/m (for 6 months, then AU$109p/m ongoing)

Offering 860Mbps download speeds during the busy evening hours, this Superloop NBN 1000 plan is one of the fastest in the country. The provider is often well-rated by online gamers too and you can also take advantage of a free Amazon eero 6+ router if you remain connected for just 18 months. What’s most impressive is that it’s some AU$912 cheaper over the first year than Telstra.

Total minimum cost: AU$99 | Total cost of first 12 months: AU$1,248 | Yearly cost after discount: AU$1,308

Spintel | AU$95p/m (for 6 months, then AU$105.95p/m)

Spintel's NBN 1000 offering has landed in the top spot for multiple users, as it boasts a massive 650Mbps — which is more than enough internet for larger households. That being said, it is on the smaller side of the NBN 1000 speed spectrum, so do take it with a grain of salt before signing up.

If you need slightly faster speeds, however, you could also consider Superloop's NBN 1000 option for a similar pricepoint and 860Mbps advertised speeds.

This offering does come with unlimited data, flexible bundle options and an AU$0 fibre upgrade for eligible addresses. But, the only minor caveat is that this plan is only available for HFC connections.

Total minimum cost: AU$95 | Total cost for first 12 months: AU$1,205.70 |Total yearly cost: AU$1,271.40
