Business NBN and Internet Services for Australian Businesses

Business NBN — reliable internet for Australian SMBs

NBN Business broadband is cost-effective, widely available across Australia, and sufficient for most businesses up to 50 users running cloud-based Microsoft 365 and Azure workloads. Mycelium 365 procures and manages NBN Business plans — handling the ISP relationship, connection provisioning, and the router and firewall configuration that determines how Microsoft 365 and Teams traffic is prioritised. Business-grade NBN plans include Service Level Agreements (SLAs) for fault resolution, unlike consumer NBN.

Available tiers: NBN 100/20, NBN 250/25, NBN 1000/50 (where infrastructure supports it).

Enterprise fibre — dedicated connectivity for larger businesses

Enterprise fibre provides dedicated, symmetric bandwidth with guaranteed uptime SLAs — suited to businesses with 50+ users, multiple sites, high Microsoft Teams Voice call volumes, or Azure workloads requiring consistent low-latency connectivity. Unlike NBN (shared infrastructure), enterprise fibre is a dedicated connection with committed information rates and 4-hour fault resolution SLAs.

Available in Melbourne, Sydney, Brisbane, Perth, Adelaide, and Canberra CBDs and major commercial precincts. Mycelium 365 manages the carrier relationship, installation coordination, and ongoing performance monitoring.

SD-WAN — intelligent connectivity for multi-site businesses

SD-WAN (Software-Defined Wide Area Network) manages traffic intelligently across multiple internet connections — routing Microsoft 365 and Teams Voice traffic over the highest-quality available path, automatically failing over to a secondary connection (4G/5G or secondary NBN) if the primary fails. SD-WAN is suited to: businesses with 2 or more sites that need consistent connectivity between them; businesses running Teams Voice where call quality is business-critical; and businesses where an internet outage means staff cannot work.

Mycelium 365 implements and manages SD-WAN using enterprise-grade hardware with central policy management — configuration changes, monitoring, and failover testing all managed remotely.

What Mycelium 365 manages beyond the internet connection

• Router and firewall configuration — traffic policies, security rules, QoS for Teams Voice and Microsoft 365
• DNS management, including DNS filtering for security
• Network monitoring — uptime, latency, packet loss, all visible in the monthly report
• Failover configuration and testing — automatic switchover to a secondary connection with quarterly failover tests
• ISP fault management — Mycelium 365 manages fault escalation with the carrier on your behalf, so you don't spend hours on hold

Internet connectivity and Microsoft 365 — why it matters

Microsoft 365, Teams Voice, and Azure all run over the internet. The quality of your internet connection directly determines the quality of your Microsoft 365 experience — Teams call quality, SharePoint file sync speed, Azure application performance. Mycelium 365 configures routers to prioritise Microsoft 365 and Teams traffic (following Microsoft's network connectivity principles), implement split tunnelling for VPN users, and ensure DNS resolution routes Microsoft 365 traffic to the nearest Microsoft network entry point.

This is a meaningful performance difference — particularly for Teams Voice where packet loss above 1% produces audible call quality degradation. Connectivity is managed alongside Microsoft 365 managed services and network security — one partner accountable for the full stack.
