What are the best unlimited NBN plans?

With increased reliance on the Internet for work, study, and entertainment, a fast and reliable home broadband service is crucial, especially for larger households. 

An unlimited NBN plan alleviates concerns about extra charges or slowed speeds, allowing you to engage in video conferences, download large files, stream HD videos, play games, and connect multiple devices without worry. 

Explore this guide to discover the best-value unlimited NBN plans for your home.

Expert picks: Best unlimited plans by speed

If you need a new NBN plan, you've come to the right place. Our selections are categorised by speed tiers, covering NBN 12, NBN 25, NBN 50, and even NBN 100 for those seeking faster options. 

We specifically focus on NBN plans with unlimited data, eliminating concerns about running out or facing excess fees. 

Best NBN 12 plan: TPG

How we chose this plan: In choosing the top NBN 12 plan, we consider the monthly cost, plan features and typical evening speeds.

To find out more about how we recommend plans, take a look at how we work.

TPG NBN 12 plans are priced at $64.99 per month and come with a free modem, unlimited data and no lock-in contracts. This NBN 12 plan has a download speed of 12Mbps and an upload speed of 0.8Mbps. 

It's a perfect plan if you're looking to lightly browse the Internet and check emails. It's worth noting that there is only a $5 difference between the NBN 12 plans and NBN 25 plans, so if you want something a little faster, it may be worth upgrading.

Best NBN 25 plan: Tangerine

How we chose this plan: In choosing the top NBN 25 plan, we consider the monthly cost, plan features and typical evening speeds.

Tangerine Telecom broadband provider logo
Tangerine Telecom Value nbn® Broadband Plan
  • Unlimited
  • 25/8 Mbps
  • Deal: $47.90 for first 6 months, then $72.90 ongoing.
$47 .90/ mth
for first 6 months, then $72.90 ongoing.
Min. total cost $47.90
To find out more about how we recommend plans, take a look at how we work.

At $64.99, Tangerine offers one of the lowest NBN 25 plans on the market. With a new customer discount of $15 per month for the first six months, customers will pay $49.99 at first. This is a plan that offers no lock-in contracts, unlimited data and free standard connections. 

Typical evening speeds sit at download speeds on offer of  25Mbps and upload speeds sit at 8.5Mbps. It’s a great plan for one or two people browsing at the same time.

Best NBN 50 plan: More Telecom

How we chose this plan: In choosing the top NBN 50 plan, we consider the monthly cost, plan features and typical evening speeds.

More Telecom broadband provider logo
More Unlimited nbn® Value Plus Broadband Plan
To find out more about how we recommend plans, take a look at how we work.

While there are plenty of NBN 50 plans on the market, choosing the best unlimited NBN plans isn't the easiest. However, we like More Telecom for the best NBN 50 unlimited plan. With a great price of $88 per month, customers get free standard connections, 7-day tech support, no lock in contracts and typical evening speeds of 50Mbps download and 17Mbps upload. 

On the other end of the price scale is Telstra, popular as a household name and offering NBN 50 plans with a free New Smart Modem 3, phone line and calls and discounts on Binge and Spotify for new customers. The snag is that Telstra charges $100 a month for its NBN 50. A little pricier, but worth it for the inclusions.

Best NBN 100 plan: Superloop

How we chose this plan: In choosing the top NBN 100 plan, we consider the monthly cost, plan features and typical evening speeds.

Superloop broadband provider logo
Superloop nbn® Family Broadband Plan
  • Unlimited
  • 95/17 Mbps

Min. total cost $82.00
To find out more about how we recommend plans, take a look at how we work.

For NBN 100, we've chosen Superloop as the winner. Not only is the price great at $85 a month, Superloop customers get more than unlimited data and no lock in fees. 

Customers also get five free Speed Boosts per month to boost their Internet speed for 24 hours at a time and a free Amazon eero+6 modem. With download speeds of 95 Mbps and upload speeds of 17Mbps, Superloop's typical evening speeds are consistent.

What to look for when choosing the best unlimited NBN plan

An NBN unlimited data plan means you don't need to worry about using up your monthly data allowance, so the Internet is always there when you need it. But there are also other things to consider when choosing the best unlimited NBN plan for your home.

Price

Opting for unlimited plans usually means a higher cost, as you pay for both the additional data and the convenience of not monitoring your monthly usage. In choosing Internet plans, the initial consideration is affordability within your budget. 

However, prioritising the lowest price alone may not be practical, as the cheapest plans often come with slower speeds or certain limitations, making them less suitable for your home. 

It's crucial to balance cost and features, ensuring that the selected plan aligns with your household's Internet needs for a well-rounded and cost-effective choice.

Speeds

Choosing the right Internet speed is crucial for smooth online activities, as uploads and downloads demand faster speeds. Unlimited data doesn't guarantee unlimited speed, likened to water pressure in plumbing. 

More devices in use simultaneously require faster Internet to prevent slowdowns during peak hours. For instance, streaming 4K content on Netflix requires 15 Mbps, meaning two TVs need at least 30 Mbps. With a 25 Mbps plan, quality drops, creating a traffic jam. 

NBN offers various speed tiers for unlimited plans, allowing easy upgrades if needed. Real-world speeds may vary based on the broadband connection and neighbourhood usage.

Providers

Your home Internet's speed and reliability depend not only on your plan and NBN technology but also on your chosen Internet provider. 

While an NBN 100 service promises a maximum download speed of 100 Mbps, actual speeds may be slightly lower. Evening speeds, when Internet use peaks, are crucial, with providers advertising "typical evening speeds" to indicate real-world performance from 7 pm to 11 pm. These speeds vary among providers, especially for plans exceeding 100 Mbps. 

Providers investing in ample bandwidth from the NBN tend to offer better speeds, while the cheapest options may sacrifice speed. Consider provider diversity, hardware choices, customer support quality, and available deals when selecting the most suitable NBN plan for your needs.

FAQs

Do I need to go on contract for unlimited NBN?

No, most Internet providers offer at least some unlimited month-by-month NBN plans without lock-in long-term contracts.

Who is an unlimited NBN plan good for?

Anyone who is worried that they, or someone else in their home, might chew through their monthly data allowance – resulting in an excess data bill or, perhaps worse, very slow Internet for the rest of the month.

Is unlimited NBN really unlimited?

Yes, if you sign up for an unlimited data plan in Australia then there shouldn't be any catches, such as cutting you off or slowing your connection if you download too much. The ACCC consumer watchdog has cracked down on Internet providers in the past who have used terms like "unlimited" when it didn't really mean it. That said, most Internet service providers still have a "fair use" policy. These policies tend to relate to using your Internet connection in an unreasonable or fraudulent manner, rather than setting a hidden limit on how much you can download every month.

Are there any restrictions on an unlimited NBN Plan?

None. When you say unlimited NBN plan, it means getting access to the Internet where you can download various content and stream movies including HD videos using different devices all at once. The best part, you no longer have to worry about speeds being capped, extra fees to pay or even slowed down speeds once you exceed your data limit. Enjoy your NBN connection as long as you want for work, entertainment and school purposes and you’ll never run the risk of shock from your bill.

Are there any risks associated with an unlimited NBN Plan?

None. So far there has been no known risks associated with the unlimited NBN plan. As a matter of fact, there are certain ISPs that include a one-month risk-free guarantee in its offers. Still, your Internet connection might be affected depending on where you live and the type of NBN connection available in your area. For example, if your home was not installed with an FTTP type connection, you may experience a little slower speed. Known to be the fastest connection type available, the Fibre to the Premises uses fibre optic connection between the fibre distribution hub and your premise. Also, some people have reportedly faced marginal problems like not getting top speed as advertised by the provider or speed of the new NBN plan was not as fast as the old service speeds.

Are you eligible for a FREE fibre upgrade?

The government is making 1.5 million Australian homes and businesses eligible for a speed upgrade to FTTP (Fibre to the Premises), which offers greater speed and reliability. Selected towns and suburbs with FTTC and FTTN are eligible for the upgrade with an eligible high speed nbn plan.
