About Caznet

Adelaide's local business telco — internet, phone systems, managed networks and data centre co-location for SA businesses and government since 2004.

In business since 2004

Over 20 years serving South Australian businesses — from small operators to enterprise and government.

100% Adelaide team

Our entire team is in SA. You call us, you speak to someone local — no offshore support, no call centres.

Own local network

We build and manage our own Adelaide network infrastructure — giving us more control over service quality and fault resolution than a reseller can offer.

Government & regulated sectors

We regularly work with local government, health, legal, education and professional services clients across SA.

Who we are

Caznet is a South Australian business telco. We supply internet, phone systems and data centre co-location to businesses, government agencies and enterprise clients across Adelaide and regional SA.

We build and manage our own local network infrastructure — giving us more direct control over service quality and fault resolution than providers who rely entirely on wholesale arrangements.

Clients we work with include:

  • Local and state government
  • Health and aged care
  • Legal and accounting firms
  • Schools and colleges
  • Retail and hospitality
  • Professional services and SMBs

How we work

  • Local support, always. When you call, you speak to someone in Adelaide. We don't run a ticket-only support model or route calls offshore.
  • Own local network. We build and manage our own Adelaide network infrastructure — so when something goes wrong, we're not just passing your problem on to someone else.
  • One team, one invoice. Internet, phones, managed networking, data centre — all from one provider. One contact who knows your setup.
  • Transparent pricing. What we quote is what you pay. No mid-contract price rises, no charges you weren't told about.
  • No unnecessary lock-ins. We earn your business month to month. Most standard services carry no fixed-term contract requirement.
