NBN Co’s free fibre upgrade program continues to roll out, bringing faster, more reliable fibre optic cabling to more and more homes in Australia. As of August 2025, NBN Co says it is on track to enable 90% of the fixed-line network to be able to access fibre technology by December 2025. The fibre technology is necessary if you want to experience multi-gigabit download speeds.
But what exactly is the free fibre upgrade program we hear you ask? Essentially it means customers who connect to the NBN fixed-line network via the inferior fibre-to-the-node (FTTN) and fibre-to-the-curb (FTTC) tech, can have the equipment at their property upgraded to FTTP. Once installed, customers can revel in the fastest NBN plans, which are soon receiving a speed boost, along with a brand new NBN 2000 plan.
NBN Co says more than 10 million homes should be able to access the superior FTTP technology by December 2025, and adds the remaining 228,000 homes on FTTN technology should be eligible to upgrade by 2030.
In order to trigger the upgrade, those eligible are required to sign up to an NBN plan with download speeds of 100Mbps or higher – those are currently NBN 100 plans, NBN 250 plans and NBN 1000 plans.
However, they're soon to be superseded and joined by NBN 500 plans, NBN 750 plans and the aforementioned NBN 2000 plans. The even better news is that these new high-speed tiers are incredibly affordable, even when compared to NBN 25 plans that are up to 25x slower. We therefore recommend anyone who is eligible to receive the free fibre upgrade, activate it at their earliest convenience.
Can I get a free NBN fibre upgrade?
The easiest way to find out if you're eligible for the free upgrade is to check your address on NBN Co’s website.
Do note that only customers that connected via FTTN/C are eligible. This means those who connect via fibre to the basement/building (FTTB) – usually those in apartment buildings – aren't eligible. However, faster internet may be available for people living in apartments via a number of NBN alternatives.
If you live in an eligible suburb, you can register for updates from NBN Co directly in order to stay in the loop – just note you’ll need to enter your address in the eligibility checker first.
Alternatively, you can wait for your telco to get in touch regarding an upgrade since it’ll be in their interest to let you know as soon as your home is eligible for an upgrade as this will encourage you to sign up for a faster NBN plan.
How much does it cost to upgrade my NBN?
The actual upgrading of the equipment at your home is free. The only cost you will incur if you use the free upgrade program is the cost of a new plan. At launch, NBN Co stipulated that customers with FTTC connections had to upgrade to at least an NBN 250 plan in order to enact the upgrade, while FTTN customers could make do with an NBN 100 plan as a minimum.
That has all changed now, however, with customers with either connection now able to get the free upgrade by simply signing up for a new NBN 100 plan. The average monthly cost of an NBN 100 plan, based on the telcos we monitor, is currently just over AU$94.
However, a handful of providers – Spintel, Exetel and Tangerine – have already released NBN 500 plans. All three are cheaper than an NBN 100 plan, and so we'd recommend upgrading to one of these instead.
What suburbs can get FTTP for free?
The full list of suburbs in Australia that are eligible for NBN Co's free fibre upgrade program is too long to list here, so we recommend you check your address on the NBN Co website to see if yours is included. If it's not, there's a good chance it will become eligible by December 2025, given the commitment to ensuring 10 million homes (90% of the fixed-line NBN network) will have FTTP access.
How do I upgrade my NBN under the free fibre program?
It's relatively simple to upgrade your home NBN connection to FTTP. The majority, if not all, internet service providers (ISPs) support the program and should advertise it on their website.
If you want to take advantage of the upgrade, simply head to the website of your ISP of choice (we've recommended some of our favourites a little further down) and enter your address.
If your home is eligible, the ISP should indicate as much. You will then need to follow the steps to sign up for a new NBN plan with at least 100Mbps download speed.
Once ordered, your ISP will arrange for NBN technicians to come to your premises to install the necessary equipment. Once installed, your new plan will activate.
What are the benefits of an NBN upgrade?
A full fibre upgrade will open households and businesses to a wider range of NBN plans, including the ultrafast NBN 1000 tier (or 'gigabit internet') as well as NBN 250, both of which are only available on certain connection types – FTTP and hybrid fibre coaxial (HFC) specifically.
The other benefit is due to arrive on September 14, 2025, when NBN Co rolls out a new Hyperfast speed tier, with theoretical speeds of up to 2Gbps. This new speed tier will also require an FTTP connection. However, 100Mbps, 250Mbps and 1,000Mbps plans will also receive a speed boost at the same time, up to fives times faster in the case of 100Mbps plans.
What are the best plans to upgrade to?
You can view our regularly updated guide to the fastest NBN plans, which has recommendations for plans starting at 100Mbps and increasing to the theoretical maximum 1,000Mbps speed. But we've also listed a few below that get our seal of approval.
NBN alternatives
If you’re on an FTTN or FTTC connection and are holding out to see if you’re eligible for an upgrade, or you’ve found out you’re ineligible, there are some NBN alternatives you should consider.
Both FTTN and FTTC connections are capable of supporting NBN 100 plans, with typical evening speeds ranging from 85-100Mbps from most providers (there are some exceptions). We’d argue this is more than enough bandwidth for most power users and large households.
However, if your current technology means that you’re experiencing a poor connection even on a higher speed tier, 5G home internet plans are becoming increasingly common, and as the rollout continues, are available in more areas.
