It’s official: NBN speed upgrades are coming next year – but will it cost you more?

NBN announces upgrades for its top-speed residential NBN plans will roll out from 14 September 2025.

NBN will be boosting speeds across NBN 100, NBN 250 and NBN 1000 plans:

• Home Fast (NBN 100) will jump from 100/20Mbps to 500/50Mbps, making it five times faster
• Home Superfast (NBN 250) will go from 250/25Mbps to a speedy 750/50Mbps
• Home Ultrafast (NBN 1000) will double its upload speed, reaching up to 1000/100Mbps

This is especially good news for speed chasers on an NBN 100 plan, which is the second most popular speed tier in Australia after NBN 50.

Good to know: The faster speeds were originally proposed to launch later this year or early next year but I guess we're going to have to be patient.

Will I be eligible for the speed upgrade next year?

These new speeds will be available to customers with Fibre to the Premises (FTTP) or Hybrid Fibre Coaxial (HFC) connections, though the exact timing of the upgrade and availability will depend on your internet provider.

If you're already on an NBN 100, NBN 250 or NBN 1000 plan, you'll automatically get the upgrade when it becomes available. Easy!

NBN will also introduce a new Home Hyperfast tier, offering speeds of up to 2Gbps. FTTP users will enjoy 2000/200 Mbps, while HFC users get 2000/100Mbps.

Households can also check their eligibility for the new speeds on NBN's website directly.

"From September 2025, more than 9 million premises will be eligible to access the highest residential speed tiers," said Anna Perrin, chief customer officer at NBN.

Australians are consuming more data than ever before and faster, higher-capacity broadband supports more high- and super-high-definition video streaming and video conferencing and smoother and lower-latency gaming, particularly when multiple devices are connected simultaneously.

Okay but are these faster NBN speeds going to cost me?

NBN says there won't be any extra cost for its speed boost where wholesale prices are concerned.

Wholesale pricing is what retailers pay to access bandwidth from NBN.

However, what you get charged as a consumer will depend on the retailer.

The catch is NBN's wholesale prices are reviewed annually and are tied to inflation so we could see higher prices eventually get passed on to consumers next year.

Plus retailers will need to update their infrastructure to help deliver these faster speeds, and the costs could again be passed on to households.

We reached out to several major internet providers for a comment and have so far heard back from Aussie Broadband and Vodafone.

"The news will herald a new era for broadband internet in Australia, and we're excited to be at the forefront with NBN to bring these speeds to light," an Aussie Broadband spokesperson told Finder.

We are, however, a little disappointed that the original timeframe wasn't adhered. In the meantime, we are already enabling some of the future experiences in market with our new Pro plans. We will continue to refine and future-proof our network in the coming year to provide unmatched speed experiences to Australians."

Vodafone too reiterated it was always supportive of initiatives to deliver faster speeds for our customers, which is also why it's giving away NBN speed upgrades at no extra cost for customers who bundle their postpaid mobile and NBN services.

Keep an eye on this space, as only time will tell the true impact on household costs!
