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 – although it is possible to get a single 4K video stream, which uses approximately 22 to 25Mbps, just be prepared for your other devices to slow down a little.
They come with a maximum download speed of 25Mbps, and the average cost has been steadily increasing in recent months, now sitting just a smidge over AU$73. The rising cost is due to NBN Co introducing higher wholesale costs, which retail service providers (RSPs) naturally, pass on to consumers.
With the average number of connected devices in Australian homes currently stated to be 25 according to NBN Co, an NBN 25 plan might not offer enough speed and bandwidth to support your needs. If this sounds like something that will affect you, we encourage you to check out our complete round up of the best NBN plans, or to jump straight into the fastest NBN plans.
Still, if you know you only need basic internet access at home, an NBN 25 plan is perfect. We've picked out our favourite options further down, comprising best overall; the best fastest and the outright cheapest.
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
Why you can trust TechRadar
Flip | 25Mbps | AU$39p/m (first 4 months, then AU$57.90p/m)
For simple, affordable and fuss-free internet, you can't go past Flip. When considering an NBN 25 plan, the vast majority of providers advertise (and will realistically be able to deliver) maximum plan speeds, so for us, choosing the cheapest option is the way to go. Enter Flip, which has the cheapest plan of the providers we monitor (and are willing to recommend). The introductory discount may only be 4 months compared to the more common 6, but both the intro and ongoing costs of Flip's plan are the most affordable available.
• AU$39 minimum cost
• AU$635.20 first year cost
• AU$718.80 ongoing yearly cost
Best fast NBN 25 plan
Mate | 25Mbps | AU$46p/m (first 6 months, then AU$76p/m with code FUTURE30)
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. If you enter code FUTURE30 at checkout, you'll not only save AU$30p/m, but also unlock a free subscription to beIN Sports. Do note that Mate's prices have increased recently by AU$6p/m across the board. This change does make the teclo slightly poorer in overall value, but we've continued to select it here for the reasons mentioned.
• AU$46 minimum cost
• AU$732 first year cost
• AU$912 ongoing yearly cost
Cheapest NBN 25 plan
Flip | 25Mbps | AU$39p/m (first 4 months, then AU$57.90p/m)

Both its first-year cost and the ongoing yearly cost is the lowest of the providers we monitor, despite only offering a 4-month discount. For greater context, this plan is just over AU$480 cheaper in the first year compared to Telstra.
• AU$39 minimum cost
• AU$635.20 first year cost
• AU$718.80 ongoing yearly cost
