Everything an Adelaide business needs
One Caznet account covers all three. Mix and match — or bundle the lot and we'll handle the cross-service integration.
Internet & Connectivity
From entry-level NBN through to enterprise-grade dedicated fibre — unlimited data and 100% Adelaide support.
Phone Systems
Modern cloud phone systems and voice services that grow with your business — no expensive hardware, no complicated maintenance.
Data Centre
Carrier-neutral co-location in Adelaide's CBD — redundant power, 24/7 biometric access and 13 carriers on-net.
Which combination is right for your business?
Three common business profiles and the Caznet combination that typically fits each.
Small office, 5–20 people
Standard office workloads — email, web, cloud apps, video calls. You need a reliable phone system and fast internet without overpaying for enterprise features you'll never use.
From ~$73 + $159/user/mth
Established SMB, 20–100 people
Downtime costs you money. You handle a lot of video conferencing, cloud apps and remote workers. You need symmetric speeds, a real SLA and a phone system that scales with your team.
From $469 + $159/user/mth · 99.95% SLA
Multi-site or data-heavy
Multiple offices, hosted infrastructure, heavy data flows, regulatory or compliance requirements. You need dedicated fibre, private connectivity between sites, and physical control of your servers.
From $299 + $550 + $34.95/ch · scoped per site
None of these match? Talk to an Adelaide specialist — we'll scope a bundle that fits.

Three services. One Caznet account.
Bundling isn't just a discount play — it changes how your business runs. Here's the practical impact when all three live on one Caznet account.
One invoice
No reconciling internet, phones and DC bills across three providers each month. One PDF, one due date, one BAS line.
Voice QoS prioritised
When phones and internet are both Caznet, we prioritise voice traffic on your circuit so calls stay clear even during big uploads or video calls.
No finger-pointing
When something breaks, you don't get bounced between the internet provider, the phone provider and the data centre. Caznet owns the whole stack.
One support number
When you call 1300 229 638, you reach an Adelaide engineer who can see every Caznet service on your account — not three separate help desks.
Every Adelaide business is different. Tell us what you need and we'll scope a combination that fits.
