Complete Business Telecom Infrastructure Built for Scale

We design, install, and support commercial communication networks from the ground up, providing communication without the corporate frustration. Unlike the big national carriers, we are actually local, meaning we deliver rapid on-site deployments and transparent agreements with absolutely no offshore call centres.

Advanced NBN Business Phone System Integration

Modernise your workflows with a high-performance NBN business phone system built around flexible 3CX and hosted VoIP technology. Our team excels at untangling your business communications mess, linking multi-site offices, distributed remote staff, and central desk systems effortlessly. Dropped call? Don’t know her.

Commercial-Grade Local Internet Service & WiFi

Stop paying for an internet connection that takes a sick day at the worst possible time. We deploy high-capacity local internet service packages, corporate fiber paths, and secure software-defined WiFi zones. To protect your revenue, our setups feature the NBN Plan B guarantee, which provides automatic backup network failovers to keep you permanently online.

Certified Telecommunications Contractors

Skip the automated runarounds and long hold queues. Our licenced, on-site field technicians handle complex structured data cabling, optical fiber path installations, MDF jumpering, and active hardware configurations. If a critical network or point-of-sale (POS) fault occurs, our real 24/7 emergency support team responds instantly to keep your business moving.

Protect your Business from NBN Disaster

NBN Plan B gives you immediate internet data when your NBN service lets you down.

NBN is a wonderful thing. But like everything, it can run into problems. Businesses can lose phones, cloud, POS and internet connections and that can run into big $ losses. We’ve heard all the horror stories and decided to do something about finding a solution – because that’s what SJH is all about!

Our NBN Plan B is a temporary fix that lets you keep doing business whilst we assist you in getting your NBN connection working. It is a vital service that can save your business thousands when your NBN connection runs into problems.

NBN Plan B

The 100% un-telco corporate advantage

We like to think of our business as being like the big national networks, but with better service and souls. We have the connection capabilities to help small, medium and large businesses but with the local team that actually cares, ensuring your business stays live and connected.

We know the unique local network bottleneck zones better than your GPS, meaning our infrastructure setups are optimised specifically for local conditions.

  • Zero bureaucracy: we promise not to transfer you seven times or force you to endure loops of terrible hold music.
  • Genuine 24/7 uptime care: our emergency care desk is managed by local network engineers who care about your data paths, not an offshore support queue reading from a script.
  • Rapid-response support teams: we resolve support requests with true speed: like, “finish your coffee before we hang up” fast.

We partner with businesses across Newcastle, Hunter Valley and NSW.
