If you're reading this article, there's a good chance you're connected to your home internet. And if you're one of the many millions of Aussies on Australia's National Broadband Network (NBN), you might be about to get a free upgrade to your connection with a planned speed boost that's fresh off the press. So, are you eligible?
NBN Co has just introduced the 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 at no additional cost for service providers, and we've already seen that many of the latter have passed these changes on to customers on NBN 100 and NBN 250 plans.
The 5x speed boost — the highest of all the planned speed increases — has been applied to the current NBN 100 tier, for a top theoretical speed of 500Mbps. These plans, for the most part, are priced nearly identically to the NBN 100 tier, making it almost a no-brainer for those with FTTP or HFC connections to elect the upgrade.
We've gathered all the available information on the latest NBN 500 tier, from availability, pricing, plans, and providers, so we can bring you the critical answers before you make the switch.

NBN 500 FAQs
When are NBN 500 plans available?
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 have spotted a number of providers already launching their 500Mbps plans.
A few providers have already joined the early launch club in debuting 500Mbps plans ahead of time. We've featured our top picks for this month above.
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$93.94p/m in September 2025. And according to our research, that statement couldn't be more true, with 500Mbps plans averaging AU$94.56p/m this month — that's around 50c more than the slower plans.
NBN plan pricing does differ greatly between telcos, though, so it will undoubtedly pay off to shop around for the best NBN 500 deals.
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 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 have been introduced for FTTP and HFC addresses.
So, post-September 14, all NBN 100 plans and above should automatically get upgraded to faster speeds. 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.
