Telstra Speed Test.
Understand your Telstra connection like never before.
The ultimate way to understand your connection. Measure live download, upload, ping and jitter—then discover what's really happening with your NBN, Wi‑Fi or 5G performance.

Live Telstra Speed Test
Real device-to-Cloudflare transfers · provider-independent
Your network. Decoded.
Start a live measurement to uncover your download and upload capacity, HTTP latency, jitter and responsiveness under load.
Measurement note: This independent tool tests the browser-to-Cloudflare route and works on any ISP. Connect via Telstra first for a Telstra-path reading. Browser HTTP latency is not ICMP ping; it cannot read modem sync, tower signal strength or Telstra account information. No affiliation with Telstra.
Connection intelligence
A deeper, independent breakdown of your service type, plan, device, signal and home network load.
How does your NBN speed stack up?
Compare measured throughput against the nominal download speed of common NBN tiers.
Plan labels are reference tiers, not promises of actual speed or an up-to-date Telstra plan catalogue. Your home wiring, access technology, plan, peak-hour congestion and device can affect performance.
What can your connection actually do?
Everyday scenarios translated from your actual measurement.

Troubleshooting playbook
Use these practical checks before deciding your internet service is the problem.
Internet running slowly?
- Test twice, several minutes apart.
- Pause cloud backups and downloads.
- Power-cycle your modem or router if safe.
- Compare results during and outside peak hours.
- Check official Telstra and NBN outage information.
Wi‑Fi versus Ethernet
- Test close to the router.
- Retest on a compatible Ethernet connection.
- Try 5 GHz or 6 GHz where supported.
- Check signal obstacles and competing networks.
- Compare in the same browser and device.
4G / 5G performance
- Test outdoors and indoors to compare.
- Check your device's own cellular network indicator.
- Disable VPN temporarily when appropriate.
- Check mobile plan caps or congestion.
- Retest in another location before diagnosing coverage.
Telstra speed test questions, answered.
Plain-English answers to the queries that bring people here.
How can I run a Telstra internet speed test?
Connect your device to your Telstra internet service, close heavy downloads and select Start Speed Test above. This independent browser test measures the internet path from your device to Cloudflare and is not Telstra's official speed-testing tool.
What is a good Telstra NBN speed?
It depends on your purchased plan, access technology, home wiring and peak-hour demand. Compare your measured download speed with your plan's nominal speed and Telstra's published typical evening speeds, not another household's plan.
Can I test Telstra Wi‑Fi strength?
This page can test performance while you're connected to Wi‑Fi, but browsers cannot accurately read your router's Wi‑Fi signal strength in dBm. Compare a Wi‑Fi reading with Ethernet and use your device's Wi‑Fi diagnostics to inspect radio strength.
Does this work for Telstra 5G and 4G?
Yes. Select Mobile / 4G / 5G and ensure your device is using cellular data. The tool measures throughput and HTTP response times but cannot access the signal strength of a mobile tower.
Why is my Telstra speed test slow at night?
Busy-hour demand, in-home Wi‑Fi contention, devices downloading updates and access-network congestion can reduce performance. Save a sequence of tests to compare evening and off-peak results.
What are ping, jitter and loaded latency?
HTTP ping is a web-request response-time estimate, jitter is variation between request times, and loaded latency measures responsiveness while the connection is busy. This is not the same as ICMP ping to a game server.
