NBN 750 plans are coming soon as a FREE upgrade – here's everything we know about the imminent NBN 250 replacement

If you're someone who keeps abreast of NBN-related news, it should probably come as no surprise to learn that NBN Co is planning to deliver some significant speed upgrades to select NBN tiers come this September.
That includes the introduction of a brand new top speed tier called NBN 2000, increasing the fastest consumer internet plans available in Australia to 2,000Mbps – or double the current maximum download speed of 1,000Mbps. However, this new tier isn't the only change on the horizon, as both NBN 100 and NBN 250 are set to receive free speed boosts, too.
From September 14, 2025, NBN Co is planning to triple the download speeds of NBN 250 plans to 750Mbps, and double the upload speeds from 25Mbps to 50Mbps – all for no extra cost. While we've yet to receive final confirmation, internet providers will likely introduce new names for these NBN plans that reflect the speed increase — in other words, NBN 250 plans may soon be renamed to NBN 750 plans.
While the wholesale speed changes were confirmed some time ago, there are still plenty of questions surrounding the new NBN 750 tier and what this means for Aussie consumers — especially those on existing Superfast 250Mbps plans.
We've gathered up all the best answers on what to expect from the new speed boost, pricing, connection types and more, so you can be prepared for the September rollout.

According to NBN Co, the new plans are rolling out on September 14, 2025. However, this will be the date that plans will be available at a wholesale level for retail service providers, and not necessarily consumers.
There is currently no definitive answer as to how NBN 750 plans will be made available to end users, as each retail service provider (RSP) is free to decide exactly how it will implement the changes. However, we believe at least some providers to be fairly rapid in passing the increased speeds on to consumers. As such, we'd expect that some providers will also have NBN 750 plans available to order for new sign ups at by both consumers and businesses by October.
According to the NBN Co, NBN 250 wholesale speeds will increase to a theoretical maximum of 750Mbps downloads and 50Mbps uploads.
If speed boosts are fully passed on by RSPs (and for traffic within Australia, there's no obvious reason why they shouldn't be), NBN 750 plans will therefore provide theoretical speeds of up to 750Mbps during the typical evening hours of 7pm-11pm. Upload speeds should also approach 50Mbps.
Do keep in mind that the 750Mbps figure is theoretical, meaning that not all customers will be able to access those speeds in the real world due to various factors including connection type, location and provider. However, considering most NBN 250 plans achieve close to their maximum theoretical speeds, it's likely that RSPs will eventually pass on this boost to end users and increase their claimed typical evening speeds to match.
What we don't know is how these new speeds will impact international internet speeds, which travels beyond the NBN. International fibre pipelines connect Aussies to services and sites hosted in other countries, such as online games servers and streaming platforms. These speeds are largely dependent on each RSP's own capacity to handle international bandwidth, which can vary greatly.
Thankfully, major sites such as YouTube, Meta and Netflix have dedicated Australian servers, and the speed increase may fundamentally deliver faster connections to these platforms. However, for other sites hosted in overseas locations, some RSPs may not have enough bandwidth to simultaneously handle thousands of customers suddenly downloading at 3x their previous speeds — particularly during the peak evening hours.
With NBN Co providing these speed upgrades to providers at no cost, NBN 750 plans should theoretically be priced similarly to NBN 250 plans — which, as of June 2025, is roughly about AU$106 per month.
Given current prices, we can reasonably speculate that NBN 750 plans could cost between AU$100p/m to AU$120p/m, in line with most NBN 250 plans right now. We suspect that potential introductory offers could reduce this to around AU$90p/m for the first six months.
NBN plan pricing does differ greatly between telcos, though, with the most expensive NBN 250 provider being Telstra, which charges AU$130p/m. The cheapest provider is SpinTel, offering its superfast plan for just AU$80p/m ongoing.
SpinTel also offers an unofficial NBN 750 plan for AU$90p/m ongoing, which is the first and therefore cheapest of its kind (so far). Much like other NBN plans, it will undoubtedly pay to shop around for the best NBN 750 deals when they debut.
As with the current NBN 250 plans, NBN 750 will only be available to homes and businesses with either fibre-to-the-premises (FTTP) or hybrid fibre coaxial (HFC) connection types.
If you're on another NBN connection type, such as FTTN, you'll likely need to upgrade to a full fibre installation to access NBN 750 plans. Thankfully, many properties are eligible for NBN Co's free fibre rollout program, which is set to provide over 10 million households with 2Gbps-capable FTTP by the end of 2025. If you want to jump into the superfast lane but haven't upgraded yet, you can check your eligibility on NBN Co's website.
If you're contemplating the switch to an NBN 750 plan, there are a few things you should consider. First off, your chosen NBN plan will depend on your household's internet needs and connection type. We've already covered the connection types you'll need above, so let's talk speeds.
If you're already on a 250Mbps plan and connect via HFC or FTTP, your plan should, in theory, automatically upgrade to NBN 750 with the speed boost. However, NBN 250 plans aren't the only ones getting accelerated this year. NBN 100 plans will get a 5x maximum speed increase to 500Mbps, and at a wholesale level, NBN 1000 plans will have their included bandwidth increased to support a minimum speed of 750Mbps. (This could, in turn, help more providers finally offer 'true' gigabit plans that reach 1,000Mbps typical evening speeds.) Alongside these increases, NBN 2000 plans will also be introduced for FTTP and HFC addresses.
So, in essence, all NBN 100 plans and above should automatically get upgraded to faster speeds. This may come with a small price increase vs current plan costs, too, given the NBN Co wholesale changes coming into effect on July 1. However, given that all tiers have received a wholesale increase of under AU$2, we don't expect prices to shift too much.
You might wonder whether upgrading to an NBN 750 plan is really necessary, and to that, we say that if you're a heavy internet user, can afford it, or just want to test out these turbocharged speeds when they become available, then go for it. However, if you're already on an NBN 100 plan, you may be satisfied with the 5x speed boost that's coming to NBN 100, and find there's no need to switch plans or providers after all. And if you're already on NBN 250, you might, in fact, want to consider downgrading from an NBN 250 to an NBN 100 in preparation for the September speed increase, which should still theoretically double your current speeds.
Right now, there are some seriously attractive NBN deals on offer from some top-rated telcos. One provider is in fact already offering an unofficial NBN 750 plan well ahead of the rollout, and that's SpinTel.
SpinTel | NBN 750 | AU$90p/m
SpinTel already has a leg up on its competition by offering this new NBN 750 plan, priced at just AU$90p/m ongoing. SpinTel claims this plan achieves its theoretical maximum 750Mbps download speed during the busy evening hours.That said, SpinTel's NBN 250 plan is currently AU$11 cheaper (or $79p/m) thanks to a six-month introductory discount, and we'd anticipate that it will be boosted for free to NBN 750 later this year. So, you could be paying a little more by opting for SpinTel's unofficial NBN 750 plan right now, instead of waiting for NBN Co's official rollout.
Total minimum cost: AU$90 | Total yearly cost: AU$1,080
