Best NBN 25 plans: our top picks for the best and most affordable internet

The best NBN 25 plans are suited for one or two people who want to browse the web at the same time, stream music and stream video in HD quality – or potentially a single 4K video stream. They come with a maximum download speed of 25Mbps, and the average cost of a plan continues to sit at around AU$70 a month – if you already know you'll need more speed and you're in the wrong place, be sure to check out our complete round up of the best NBN plans.

You can easily spend less than that each month, with 15 NBN providers either hitting that mark or charging less on a regular basis, meaning there's plenty of choice when searching for the best plan for your household.

We've given you a helping hand further down by picking our favourite provider across three different categories: best overall; the best fastest and the outright cheapest. Low cost internet service provider (ISP) Flip was once unrivalled in all three categories, but following some changes to its pricing and aggressive discounts from other providers, that's no longer the case.

If you’re currently on a 25Mbps plan but you’re wanting to move up to something faster, you may want to check out the best NBN 100 plans and take advantage of the NBN Co's free fibre upgrade program. Alternatively, the equipment already at your premises will be able to support the best NBN 50 plans.

Best overall NBN 25 plan

Flip25MbpsAU$39p/m

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

Flip remains our favourite option overall, and it's been helped considerably by an exclusive WhistleOut offer that increases the introductory price promotion to 6 months (up from 4 months with Flip directly). As a result, Flip is now unequivocally the cheapest provider for an NBN 25 plan.

• AU$39 minimum cost
• AU$581.40 first year cost
• AU$694.80 ongoing yearly cost

Best fast NBN 25 plan

Mate | 25Mbps | AU$40p/m MATE30

Mate | 25Mbps | AU$40p/m (first 6 months, then AU$70p/m with code MATE30)

We've selected Mate as the best fast NBN 25 plan due to its claimed upload speeds of 10Mbps. Of the providers we monitor, this is the fastest available, with the majority of other providers claiming 8Mbps or less. The real world difference is unlikely to be huge, but for our money we'd like to get the best possible experience. A faster upload speed will benefit anyone carrying out video calls or needing to upload files to online cloud services.

• AU$40 minimum cost
• AU$660 first year cost
• AU$840 ongoing yearly cost

Cheapest NBN 25 plan

Flip25MbpsAU$39p/m

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

This spot was previously occupied by Dodo due to it offering a first-year saving of AU$240. That deal has now ended and the one it's been replaced with now doesn't quite match Flip's pricing, especially with the aforementioned WhistleOut exclusive discount. That means Flip has now reclaimed its crown as the cheapest NBN 25 plan provider, both in the first year and each ongoing year.

• AU$39 minimum cost
• AU$581.40 first year cost
• AU$694.80 ongoing yearly cost

NBN 25 FAQ

How fast is NBN 25?

Aside from NBN 12, the speed offered by NBN 25 is the slowest of the NBN tiers, with download rates up to 25Mbps and uploads of between 4Mbps and 10Mbps, depending on your plan.

These speeds may be affected by the type of connection and signal strength within your home, but it’s less likely to be impacted than the higher speeds by these factors, even during the peak busy period between 7pm–11pm. Among the NBN providers monitored by TechRadar, the advertised typical evening speed is 25Mbps on average.

How much does NBN 25 cost?

A good majority of telcos offer their NBN 25 service for about the same cost, with AU$65 monthly being a reasonable price to pay. The average monthly price for an NBN 25 plan is currently AU$70.

Most telcos with NBN 25 plans also offer an introductory discount, slashing the price by as much as AU$15p/m for the first half-year of your plan.

More premium telcos such as Telstra are at the other end of the spectrum, charging as much as AU$89 per month, but these plans will sometimes come with other extras such as a phone line or streaming service inclusion.

Can I get NBN 25?

If you’re not in a regional area or one of the few other locations that haven’t had a fixed line NBN service set up, then you’ll be able to get an NBN 25 connection. All connection types, such as fibre-to-the-node (FTTN) and hybrid fibre coaxial (HFC), are able to support NBN 25.

What providers have NBN 25?

There are very few (if any) providers at this stage not offering NBN 25, as it’s the go-to budget option on offer, but still promises enough speed for a lot of households to get by.
