NBN 500 speed boosts start in September — does your plan qualify for the FREE upgrade?
If you’re reading this article, there’s a reasonable chance you’re connected to your home internet service. And if you’re one of the many millions of Aussies on Australia’s National Broadband Network (NBN), you may be about to receive a free upgrade to your connection thanks to a planned speed boost coming in a few short months. So are you eligible?
In September, NBN Co is preparing to shake up the Australian broadband landscape by introducing a new fastest speed tier (NBN 2000) alongside up to 5x speed boosts for existing tiers (NBN 100 and NBN 250) for free. Yes, you read that right — these wholesale changes to existing tiers are coming in at no additional cost for service providers, so we expect many of the latter will pass these changes on to customers on NBN 100 and NBN 250 plans.
The 5x speed boost — the highest of all the planned speed increases — will be applied to the current NBN 100 tier, for a top theoretical speed of 500Mbps. There’s no confirmation yet on what these plans will actually be called, so much like the NBN 750 plans that will replace NBN 250, we’ve chosen to dub this particular tier as ‘NBN 500’, to reflect its 500Mbps top speed.
So, what exactly does that mean for you and your existing NBN connection, how much will the speed boost cost for customers, and is it worth the switch? We’ve gathered all the available information currently available to bring you the critical answers.

NBN Co has announced that the new plans will be accessible to retail service providers starting on September 14, 2025. This is the official wholesale rollout date for providers, so while the speed bumps might not immediately be available to end users, we anticipate that at least some providers will have NBN 500 plans ready for residential and business orders sometime in October.
How fast will NBN 500 plans actually be?
From September, an NBN 100 plan on a fibre to the premises (FTTP) or hybrid fibre coaxial (HFC) connection will offer five times faster wholesale download speeds (500Mbps) and double the upload speeds (50Mbps), according to NBN Co.
If such speed boosts are passed on by RSPs — and there’s no major reason why they shouldn’t be, if you ask us — NBN 500 plans should provide theoretical download speeds of up to 500Mbps.
Do note that the 500Mbps figure is theoretical, as real-world speeds may vary due to factors like connection type, location, internet service provider and the speed of the service you’re connecting to. However, given that most NBN 100 plans achieve speeds close to (or in some cases, over) their theoretical maximum, it’s likely that RSPs will increase their claimed typical evening speeds to something approaching 500Mbps, and pass the increase on to end users.
What we don’t know yet is how these new speeds will impact international internet speeds that travel beyond the NBN, which as the ‘national’ in its name suggests, only connects directly to sites and services within Australia. Each service provider utilises international fibre pipelines connect Aussies to servers hosted in other countries, which can include things like online games servers and more niche streaming platforms. These speeds are largely dependent on each service provider’s own capacity to handle international bandwidth, which can vary greatly.
Thankfully, major sites or web companies such as YouTube, Netflix and Meta (for Facebook and Instagram) have dedicated Australian servers, and the speed increase may help immediately 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 5x previous speeds — particularly during the peak evening hours.
What will a NBN 500 plan cost?
With NBN Co providing these upgrades to RSPs at no extra cost, NBN 500 plans should theoretically be priced similarly to NBN 100 plans — which average AU$92.01p/m in June 2025.
Given current prices, we can reasonably speculate that NBN 500 plans could cost between AU$80p/m to AU$100p/m, in line with most NBN 100 plans ongoing costs right now. We suspect that potential introductory offers could reduce this to around AU$75p/m for the first six months.
NBN plan pricing does differ greatly between telcos, though, with the most expensive NBN 100 provider being Telstra at AU$110p/m. The cheapest provider on the tier is SpinTel, at just AU$70p/m (for 6 months, then AU$86.95p/m ongoing).
Much like other NBN plans, it will undoubtedly pay to shop around for the best NBN 500 deals when they officially debut.
What connection types will be compatible with NBN 500 plans?
As with all fixed-line NBN plans advertising over 100Mbps, NBN 500 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 fibre to the node (FTTN), you’ll need to upgrade to a full fibre installation to access NBN 500 plans. Thankfully, many properties are eligible for NBN Co’s free fibre rollout program, which is set to provide over 10 million households with FTTP by the end of 2025. If you want to jump over to one of these new faster plans but haven’t upgraded yet, you can check your eligibility on NBN Co’s website.
Should I switch to a NBN 500 plan?
If you’re considering switching to a NBN 500 plan, there are several factors to weigh. Firstly, the best NBN plan for your needs largely depends on your household’s internet requirements and connection type. We’ve already discussed the connection types you’ll need above, so what about speeds?
Well, if you’re already on a 100Mbps plan and connect via HFC or FTTP, your plan should theoretically automatically be upgraded to NBN 500 with the speed boost. However, NBN 100 plans aren’t the only ones getting accelerated this year. NBN 250 plans will get a 3x maximum speed increase to 750Mbps, 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, post-September 14, 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 anticipate that prices will change too much.
You may find that manually switching to NBN 500 isn’t necessary, especially if you’re already on a NBN 100 plan and have an FTTP connection. If you’re currently on a 250Mbps plan, you may even want to consider downgrading to 100Mbps, as the planned 5x speed boost to that tier will not only double your current 250Mbps speeds, but should also cost you less.
Now, 500Mbps is a lot of internet — it’s 10x more than what’s offered by NBN 50 plans, which continue to be the most popular speed with Aussie households according to the ACCC. That tier’s 50Mbps top download speeds are often fine for households of up to four users. But, with data predicting that most homes will have over 40 internet-connected devices by 2030, you may want your speeds boosted after all. If you have the right connection type to sign up for an NBN 500 plan and were already considering an upgrade from a slower speed, we’d suggest giving it a go, and if you find the speeds aren’t necessary, you can always drop back down to a slower plan.
Our favourite fast NBN plans
There are plenty of great NBN deals on offer at the moment, thanks to EOFY sales. Currently, our top-rated NBN 100 plan is offered by Aussie Broadband, which includes a AU$10 discount each month for the first six months.
We’ve also included Superloop’s NBN 1000 plan, as EOFY is an ideal time to try out the current top speed before the new tiers roll out. You can then decide to switch to one of the latter plans once your introductory offer ends.
