The fastest NBN plans are those that deliver download speeds of 100Mbps of faster. Currently, there are three speed tiers available to households that are considered high-speed NBN plans: NBN 1000, NBN 250 and NBN 100. These numbers indicate the theoretical maximum download speed available on each plan, in megabytes per second. NBN Co has confirmed even faster 2Gbps 'Hyperfast' NBN plans will arrive in September 2025.
However, while many internet service providers (ISPs) claim to deliver maximum speeds on NBN 100 and NBN 250 plans, there is still just a handful of providers that quote speeds close to the 1,000Mbps potential of NBN 1000 – although the situation is definitely improving.
Our recommendations for the fastest NBN plans come from crunching the numbers, and finding plans which offer top speeds in their respective tiers for a fair price. We’ve partnered with WhistleOut to compare NBN plans from over 30 Aussie providers to make our top picks on this page – you can also skip ahead to the speed you want by clicking on the links below:
Can you get NBN 250 or NBN 1000?
Not everybody will be able to sign up for a high-speed NBN 250 or NBN 1000 plan. These speed tiers are only available on two types of NBN connection – fibre to the premises (FTTP) and hybrid fibre coaxial (HFC). If your household is serviced by an FTTP or HFC installation, you should be able to sign up to an NBN 250 or NBN 1000 plan.
All NBN connection types should be able to support 100Mbps speeds, but if you want to be sure, then you'll want to see if you can get a free fibre upgrade and have FTTP technology installed at your premises.

Our choice for large households and those who want a little extra speed
• NBN 100 plans are the most broadly available fast plans, with the telcos reporting a typical evening speed of 97Mbps on average.
Best NBN 250 plan
The go-to for lightning-quick broadband
• The availability of NBN 250 plans is now almost on par with that of NBN 100, with telcos reporting a typical evening speed of 237Mbps on average.
Since we first created this guide to the fastest NBN plans, the number of internet service providers quoting close-to maximum typical evening speeds on the NBN 250 has increased considerably, creating greater competition in the process.
Telstra and AGL plans are on the more expensive side, and Southern Phone has such bad reviews online that we feel we can't recommend it. We've therefore look at the remaining NBN providers and taken into account other factors they offer to settle on an overall pick.
Spintel is our top pick in the overall best NBN plans, but if you want the absolute fastest speeds, Superloop is our pick.
Best NBN 1000 plan
The fastest you can get, but only available in select locations
• The once sparse NBN 1000 tier is growing in availability, with an average typical evening speed of 690Mbps reported by the telcos.

Fast NBN FAQ
What are NBN 1000 real world speeds?
The Australian Competition & Consumer Commission conducts quarterly reports focusing on the broadband performance in Australia. Its latest report, published in December 2024, found the average download speed ranged across the day from 852Mbps to 868Mbps.
These are undeniably fast, but still a fair way off the theoretical top speed available on these plans of 1,000Mbps. Outside of the peak busy period, we’ve seen real-world speed test results that are much higher at 900Mbps, though still not reaching the maximum amount.
What are NBN 250 real world speeds?
The second-fastest tier is NBN 250, which the NBN Co refers to as 'Superfast'. The amount of providers which offer an NBN 250 plan has grown significantly in the past two years, and it’s now almost on par with the number which offer NBN 100 plans. Among the telcos we monitor, the average download speed on these plans is 235Mbps during the evening hours. Actual speed does vary among the internet providers with NBN 250 plans, so be sure to read the fine print.
What are NBN 100 real world speeds?
The NBN 100 tier is the most affordable option from the fastest NBN category, and you can expect a typical evening speed of 98Mbps on average. While the tiers mentioned above are leaps and bounds ahead in terms of speed, they are also limited in their availability – only FTTP and HFC connections can sign up to NBN 1000 and NBN 250 in most cases.
NBN 100 is referred to as 'Fast' by the NBN Co – it’s available for most connection types, and is often the fastest option available for the millions of Australians using fibre-to-the-node (FTTN) technology. If you want the top typical evening speed of 100Mbps for your NBN 100 plan, only a select few providers offer it: Telstra, Optus, Belong, Dodo, Exetel, Pennytel, Southern Phone and Spintel.
You can read more about each connection type in our guide to the best NBN plans.
