NBN Speed Guide 2026: Which Tier Do You Need?
Every NBN speed tier explained, what each one actually handles, and a household-by-household recommendation — so you pay for the speed you need, not the speed a salesperson wants to sell you.
Every NBN tier, ranked
There are seven wholesale NBN speed tiers, named for their maximum download speed in Mbps. Not every tier is available on every connection — NBN 250, 500 and 1000 usually require FTTP or HFC.
| Tier | Download | Upload | Best for | Verdict |
|---|---|---|---|---|
| NBN 12 | 12 Mbps | 1 Mbps | Light browsing, email, one HD stream on a single device. | Only choose this if budget is the sole constraint. It struggles the moment a second person uses the internet. |
| NBN 25 | 25 Mbps | 5 Mbps | Small household, 1-2 simultaneous HD streams, video calls. | The realistic minimum for a couple. Fine for browsing and one 4K stream if nothing else is happening. |
| NBN 50 | 50 Mbps | 20 Mbps | A family doing 2-3 HD/4K streams plus general use. | The sweet spot for most Australian households. Good balance of price and headroom. |
| NBN 100 | 100 Mbps | 20-40 Mbps | Large households, 4K on multiple TVs, working from home, console game downloads. | Best value for a busy family or a home worker. Recommended if you have 4+ active devices. |
| NBN 250 | 250 Mbps | 25 Mbps | Heavy downloaders, 4K everywhere, cloud gaming, large households. | Worth it only if you have FTTP or HFC and genuinely saturate a 100 Mbps connection. Most homes will not notice. |
| NBN 500 | 500 Mbps | 50 Mbps | Power users, big households, content creators uploading large files. | Niche. Only justifiable for creators or households with many heavy users on FTTP. |
| NBN 1000 (Gigabit) | 1000 Mbps | 50-400 Mbps | Tech enthusiasts, home servers, simultaneous 4K + cloud gaming + big downloads. | Overkill for almost every household. Choose it for the upload or the e-peen, not because you need it. |
Which tier for your household?
A quick recommendation by household profile. For a precise number based on your actual devices and activities, use the speed calculator.
Solo, light use (browsing, streaming)
NBN 25
One person, one or two screens — 25 Mbps covers HD streaming and video calls with room to spare.
Couple, 1-2 screens
NBN 50
Two 4K streams or one stream plus a video call fits comfortably; headroom for guests.
Family, 3-4 screens, WFH
NBN 100
Multiple 4K streams, video calls and downloads at once without anyone buffering.
Large family / share house, 5+ devices
NBN 250
Heavy concurrent use — but only worthwhile if your connection technology (FTTP/HFC) can deliver it.
Content creator / home server
NBN 250-1000
Large uploads benefit from the higher upload tiers; pick based on upload, not download.
The takeaway
NBN 50 is the default for most households: enough headroom for two 4K streams or a family’s evening mix of streaming, browsing and calls, at a price that is not much more than NBN 25.
NBN 100 is the upgrade that actually matters — for busy families, home workers and anyone with four or more active devices. Beyond 100 Mbps, most households gain very little.
NBN 250 / 500 / 1000 only pay off for power users and creators, usually because of the higher upload rather than the download — and only if your connection technology can deliver them.
NBN speed FAQs
Which NBN speed tier do I need?
For most Australian households the answer is NBN 50 or NBN 100. NBN 50 suits a couple or small family doing 2-3 simultaneous HD/4K streams. NBN 100 is the right choice for a busy family, a home worker, or any household with 4+ active devices. Go higher than 100 Mbps only if your connection technology (FTTP or HFC) supports it and you genuinely saturate your current speed. Use the calculator above for a tailored recommendation.
What are the NBN speed tiers in Australia?
The seven wholesale NBN speed tiers are NBN 12, 25, 50, 100, 250, 500 and 1000 (Gigabit), named after their maximum download speed in Mbps. Upload speeds range from 1 Mbps on NBN 12 up to 50-400 Mbps on gigabit. Not every tier is available on every connection technology — NBN 250/500/1000 typically require FTTP or HFC.
Is NBN 50 enough for Netflix and gaming?
Yes. Netflix 4K needs about 25 Mbps per stream, so NBN 50 comfortably handles one 4K stream plus browsing and a video call. For a household that watches 4K on multiple TVs at once, step up to NBN 100. Gaming itself needs little bandwidth (under 5 Mbps) but benefits from low latency and a wired connection rather than more raw speed.
Why is my NBN speed slower than I pay for?
The four usual causes: (1) your connection technology caps the speed — FTTN and FTTC often cannot deliver 100+ Mbps regardless of the plan; (2) Wi-Fi, which loses speed over distance and through walls — test with a wired Ethernet connection first; (3) an old router; (4) evening congestion on some ISP networks. Run a wired speed test before blaming the plan.
Is gigabit NBN (1000 Mbps) worth it?
For almost every household, no. A busy family with multiple 4K streams and downloads rarely peaks above 100-200 Mbps. Gigabit only makes sense for content creators who need fast uploads, home server operators, or very large share houses — and only if you have FTTP. Most of the value of gigabit plans is in the upload speed, not the download.
What upload speed do I need on the NBN?
Video calls need 1-3 Mbps up, livestreaming 6-12 Mbps up at 1080p60, and large cloud backups scale with file size. NBN 50 gives 20 Mbps up, which covers video calls and streaming comfortably. If you upload large files regularly (video editing, photography), look at the higher upload tiers on NBN 250/500/1000, where upload is the real differentiator.
