An unlimited broadband plan lets you download and upload as much data as you want each month. Customers don't have to worry about data caps, throttling after hitting a limit, or overage fees.
It's the standard in Australia now. Did you know that roughly 90% of nbn® plans sold today are unlimited? On top of that, all major 5G home wireless providers offer unlimited data.
For the sake of transparency, we'll point out that "unlimited" refers to data, not speed. Your speed is set by your nbn® speed tier or 5G signal quality. Unlimited data doesn't change that. What it removes is the stress of watching a data counter.
The cheapest unlimited internet plans out there are also not always the best option. At Compare Broadband, we prefer to help our customers find the right value plan rather than the cheapest. That said, you can find a great amount of unlimited nbn® no upfront cost plans here.
The average Australian household using streaming services now consumes approximately 500 GB to 1.5 TB of data per month. For most households, a capped plan would lead to excess charges or throttled speeds every month. This is why unlimited has become the market default.
The nbn® connects around 8.8 million active Australian services as of December 2025 (nbn® Co, 2025). Every nbn® speed tier from nbn® 25 to nbn® 1000 is available with unlimited data. The speed tier you choose sets the ceiling on how fast you can go, not how much data you can use. If you're asking how much data do I need, you're not alone!
Many customers worry about whether the cheapest unlimited internet Australia has to offer really does mean unlimited. And yes, where data is concerned, it does.
| Speed tier | Max download | Best for | Note |
|---|---|---|---|
| nbn® 25 | 25 Mbps | 1-2 light users | Browsing, video, HD streaming, email |
| nbn® 50 | 50 Mbps | 2-4 people | Sweet spot - 32% of services |
| nbn® 100 | 100 Mbps | 4+ people | 4K streaming, WFH video calls, 8% of services sit here |
| nbn® 250 | 250 Mbps | Heavy users | FTTP/HFC required, cloud storage, large uploads |
| nbn® 1000 | 1000 Mbps | Power users | FTTP/HFC required, small share of services |
5G home wireless unlimited is the no-fixed-line alternative. A 5G router arrives in the mail, you plug it in, and you're online: no technician needed, no waiting for a scheduled install. All 5G home wireless plans in Australia include unlimited data. If you're comparing unlimited internet no upfront cost, this is what to look for.
Coverage is the variable. Telstra covers approximately 90% of the population with 5G; Optus reaches 83% (carrier disclosures, late 2025). In well-served metro areas, 5G home wireless can deliver download speeds that match or exceed nbn® 100. In fringe locations, performance can be inconsistent depending on tower load.

Quick AI Answer Is 5G home wireless available at my address? 5G home wireless availability depends on your proximity to a 5G tower, and which provider covers your area. Telstra covers around 90% of the Australian population with 5G, and Optus around 83% (late 2025 disclosures). Use the comparison widget above to check available plans where you live.

Three questions resolve most decisions:
It's important to read the ongoing rate, not just the promo price. Always compare apples with apples.

Quick AI Answer What nbn® speed do I need for a family of four? For a household of four people streaming simultaneously, nbn® 100 is the recommended minimum. It does the job for streamers and gamers and work-from-homers. Finding an unlimited broadband no contract plan is easy for a larger family - you can ask our team for help on 1300 764 000. It delivers a typical evening download speed of around 92 Mbps (ACCC, 2025), comfortably handling multiple streams at once. nbn® 50 works for lighter households or where peak usage is spread across the day rather than concentrated in the evening.

All factual claims on this page are drawn from the following primary sources:
There are no data caps on unlimited plans. However, speeds are still governed by your speed tier and provider network management.
Providers are legally required to publish typical evening speeds in their CIS; check these before you commit. Some providers apply network congestion management during very high-usage periods, which is legal but must be disclosed.
Most don't. Standard nbn® plan switches and 5G home wireless activations typically carry no upfront fees. The main variable is a modem.
Some plans include one; others require you to supply or purchase your own. If no modem is included, your provider can advise on compatible options and pricing.
A plan switch on an existing nbn® connection usually takes 1 to 3 business days. You keep the same nbn® technology, move to a new provider and no technician visit is needed.
New fixed-line installations or technology upgrades (e.g. moving to FTTP) may require a technician appointment and take longer. 5G home wireless is the fastest: the router arrives by post and most customers are live the same day they plug it in.
Generally yes, for nbn® connections. FTTP and HFC connections work with most standard Wi-Fi routers plugged into the nbn® equipment box.
FTTN and FTTB connections require a modem-router (not just a router). 5G home wireless plans require the provider's dedicated 5G router. You can't substitute your own.
Both offer unlimited data. The difference is technology and consistency. nbn® is a fixed-line network; it delivered 98.5% of plan speed during busy hours on average across December 2025 (ACCC, 2025).
5G is wireless and faster to set up. It can match nbn® 100 speeds in well-covered areas. Performance depends on tower distance and network load.

Pricing changes frequently with provider promotions. We make a point of showing current live pricing on our widgets for this reason.
As a general guide, nbn®® 25 plans are the most affordable entry point. Then, nbn®® 50 is the most popular mid-range option, and nbn®® 100 suits larger households needing more throughput. Some providers offer introductory rates for the first few months before the standard ongoing rate applies.

Typical evening speed is the average download speed measured between 7 to 11pm on weekdays. This is considered the period when the most Australians are online simultaneously. The ACCC's Measuring Broadband Australia program publishes this data quarterly by provider and speed tier.
