The best internet in Harkaway.
Guaranteed.
TNH Air is a fixed wireless network we built ourselves for Harkaway VIC 3806 and parts of Beaconsfield Upper — fed by Telstra fibre. Low latency, real upload speeds, and the people who built it on the other end of the phone.
30-day money-back guarantee
If TNH Air isn't the best connection you've had in Harkaway, tell us within 30 days and we'll refund you. No lock-in contract, so you're never stuck.
Starlink customers
Moving from Starlink?
Lower latency, far higher uploads, and a local team instead of a ticket queue. Ask us about our special offer for Harkaway residents switching off satellite.
Built for Harkaway, not adapted to it
Harkaway is hilly, leafy and on the edge of the nbn footprint. Big-network internet here is a compromise. We built something that isn't.
Latency under 10 ms
Tower → fibre → internet, under 10 ms to our core. That is typically snappier than most nbn cabled types (FTTN and HFC), and well ahead of nbn Fixed Wireless or satellite. Video calls stay crisp and games feel instant.
Uploads that actually upload
From 10 Mbps on Lite to 100 Mbps on Studio. Cloud backups, sending footage, working from home — the direction most connections in Harkaway neglect.
Local, 24/7, ours
The network is ours end to end, so the person you call can see your link and fix it. No wholesaler ticket, no offshore call centre.
Consistent at 8pm
We size our backhaul for the homes on each tower. The speed you pay for is the speed you get in the evening, not just at 3am.

Harkaway internet questions
What is the best internet in Harkaway?+
For most Harkaway homes with line of sight to one of our towers, TNH Air. It is the only network built specifically for Harkaway: our own towers, fed by Telstra fibre, with latency under 10 ms, uploads up to 100 Mbps and the people who built it answering the phone. Where TNH Air is not available we will tell you straight and connect you on nbn instead — we sell that too.
Is TNH Air available at my address?+
Most of Harkaway and parts of Beaconsfield Upper and surrounds are within reach of our towers. TNH Air needs a clear line of sight to a tower, which we confirm at install. Enter your address on our plans page and we will tell you what we can do.
How fast is TNH Air in Harkaway?+
Residential plans run from 15/10 Mbps up to 250/100 Mbps, and the speed you pay for is the speed you get — there is no shared evening slowdown like a congested nbn tower. With clear line of sight we can build custom links up to 1000/1000 Mbps for businesses and power users.
What does “guaranteed” actually mean?+
A 30-day money-back guarantee on every TNH Air residential plan. If it is not the best connection you have had in Harkaway, tell us within 30 days and we will refund you. No lock-in contract either, so you are never stuck.
What does it cost?+
Plans start from $50 a month with unlimited data. Setup is $199 and includes your first month of internet. No lock-in contracts, and prices include GST.
I am on Starlink. Is it worth switching?+
Starlink is a good service and we will not pretend otherwise. TNH Air gives you lower latency (under 10 ms versus typically 25–60 ms), much higher upload speeds and a local team rather than a support ticket. We also have a special offer for Harkaway residents moving off Starlink — ask when you get in touch.
Who do I call when something goes wrong?+
Us. (03) 5910 4220, 24/7. The network is ours, so there is no logging a fault with a wholesaler and waiting days for a callback — the person you speak to can see your link and fix it.
Does TNH Air cover Beaconsfield Upper?+
Parts of Beaconsfield Upper VIC 3808 are within reach of our Harkaway towers. TNH Air needs a clear line of sight, which we confirm at install. Check your address on our plans page and we will tell you what we can do.
Is there nbn in Harkaway?+
Some Harkaway addresses can get nbn Fixed Wireless or Sky Muster. We sell nbn too. If TNH Air has line of sight we usually recommend it for latency and upload; if it does not, we will connect you on nbn instead.
Do you cover suburbs near Harkaway?+
Our towers sit in Harkaway and reach into Beaconsfield Upper and nearby hills. If you are close by — for example the edges of Berwick or Narre Warren North — check your address. Line of sight to a tower is what matters, not the suburb name on the letterbox.
