Testing your NBN connection
The National Broadband Network is a wholesale network: you buy your plan from a retailer, but the line belongs to NBN Co. The technology at your address (FTTP fibre, HFC cable, FTTC or FTTN copper) decides which tiers you can get. Since 14 September 2025, fibre and HFC homes on the old 100 and 250 tiers were moved to 500/50 and 750/50, and an NBN 2000 tier was added.
This test detects your provider automatically and measures download, upload, ping, jitter and latency under load against the nearest server on Cloudflare's network. Enter your plan speed under the result to see the percentage you really get.
NBN speeds by plan
| Plan | Download | Upload |
|---|---|---|
| NBN 25 / NBN 50 | 25 / 50 Mbps | 5 to 20 Mbps |
| NBN 100 (copper FTTN, FTTB, FTTC) | 100 Mbps | 20 or 40 Mbps |
| NBN 500 (Home Fast, FTTP and HFC) | 500 Mbps | 50 Mbps |
| NBN 750 (Home Superfast) | 750 Mbps | 50 Mbps |
| NBN 1000 and NBN 2000 (Ultrafast, Hyperfast) | 1,000 to 2,000 Mbps | 100 to 200 Mbps |
Wholesale NBN tiers; your retailer's plan shows its own typical evening speed, which is the figure to compare your tests with. Checked on 31 October 2026; tiers change and vary by address, so confirm on the NBN website.
What result should you expect?
On NBN 500, the ACCC's measurements show most services reaching close to 500 Mbps in the evening. On copper (FTTN), speed depends on the line length: a long line may never reach 100 Mbps. Compare an evening wired test (7 to 11 pm) with your plan's typical evening speed.

Common reasons for slow NBN speeds
- Still on NBN 100 with fibre or HFC: ask your retailer to move you to NBN 500, usually at a similar price.
- FTTN line length: if speed is far below the tier, ask about the fibre upgrade program for your address.
- Wi-Fi limits on NBN 750+: test over Ethernet; see fibre slow on Wi-Fi.
- Evening slowdowns: see internet slow in the evening.
Before contacting NBN support
- Restart the modem and the NBN connection box.
- Run wired tests between 7 and 11 pm on several days.
- Contact your retailer (not NBN Co) with your results; it is responsible for your service.
- If speeds stay below your plan, check for traffic throttling, then contact support with your saved results.

Frequently asked questions
What is a good NBN speed?
One close to your plan's typical evening speed. For NBN 500, that is usually 450 to 500 Mbps on a wired connection.
Why can't I get NBN 500?
NBN 500 and faster tiers need a fibre (FTTP) or HFC connection, or an upgraded FTTC line. FTTN copper lines top out at NBN 100.
Who do I contact about slow NBN?
Your retailer, such as Telstra, Optus or TPG. It manages your service with NBN Co and must act on a speed problem.
