Reliable Business Internet Built for Australian Business
Why choose Summit Internet?
We Own Our Network
A Genuine Alternative to the NBN
Our fixed wireless network delivers symmetric speeds without the shared congestion of NBN. No contention from residential users streaming video at peak hour. No waiting months for an NBN connection that underperforms on day one.
Fixed wireless from Summit gives you dedicated, business-grade bandwidth with faster deployment — connected in as little as 10 business days.
100% Business. Zero Residential.
Every customer on our network is a business. That means every decision we make — from network design to support staffing — is built around what businesses need: uptime, speed, and someone who picks up the phone when it matters.
Local Melbourne Support That Knows Your Name
One Provider for Everything
Internet, phone system, mobile SIMs, and 4G backup — all from one provider, on one bill, with one support team. When your voice and data run on the same network, we can prioritise call quality automatically. When your primary connection drops, your 4G backup kicks in without you lifting a finger.
Proven Over 25 Years
Summit Internet has been operating since August 2000. We have served businesses through the rise of broadband, the rollout of the NBN, and every industry disruption in between. We are still here, still independent, and still focused on the same thing: making sure your business stays connected.

Why Australian Businesses Choose Summit Internet
Business-ready connectivity that grows with you.
Do I have to use fixed wireless, or can I get NBN through Summit?
We offer multiple access technologies including our own fixed wireless, Business NBN, Ethernet over Fibre, and MPLS. We will recommend the best option — or combination of options — based on your location, speed requirements, and budget. Many of our customers pair a primary connection with 4G backup for complete peace of mind.
Is Summit Internet only available in Melbourne?
Our fixed wireless network covers 500+ suburbs across 4,500+ km² of the Melbourne metropolitan area. For services like Business NBN, Ethernet over Fibre, mobile SIMs, and hosted voice, we can serve businesses across Australia. Call us on 1300 049 749 to check availability.
What happens if my internet goes down?
If you have our 4G backup service, your connection fails over automatically — often before you even notice. For faults on our fixed wireless network, our Melbourne-based engineering team responds directly without needing to log a ticket with a third party. That is the advantage of owning the network.
Can I get internet, phone, and mobile from Summit on one bill?
Yes. We provide internet, hosted phone systems (FlexPBX), SIP trunks, 1300/1800 numbers, fax to email, mobile SIM plans, mobile broadband, and 4G backup — all on a single account with a single support team. One provider, one bill, no finger-pointing.
How quickly can I get connected?
Fixed wireless connections can be installed in as little as 10 business days. If we do not meet that timeframe, your first month is on us. NBN and fibre connections depend on infrastructure availability at your premises, but we manage the entire process and keep you informed every step of the way.
