Not all business internet is the same. We compare standard Business NBN with Enterprise Ethernet to help you choose the right connection for your team.
Not all business internet connections are the same — and the difference between a $100/month Business NBN plan and a $600/month Enterprise Ethernet service is not just price. Understanding what you are getting for each price point helps you make the right investment for your business’s connectivity requirements.
Business NBN: What You Are Getting
Business NBN (offered by ISPs like Aussie Broadband Business, Telstra Business, and others) uses the same nbn co infrastructure as residential NBN — the same nodes, cables, and exchange equipment. What differs is:
Higher speed tiers: Business NBN plans offer higher symmetrical or higher upload speeds than residential equivalents. Common business tiers include 100/20 Mbps, 250/25 Mbps, 500/50 Mbps, and in some areas, 1000/50 Mbps.
Priority traffic management: Business plans typically have better traffic management during peak periods compared to residential plans — but this is an ISP-level policy, not a guarantee of uncontended bandwidth.
Better SLAs and support: Business NBN comes with faster fault restoration commitments (typically 8-12 business hours for critical faults vs best-efforts on residential) and business-hours or 24/7 support access.
Symmetrical upload on some plans: Some business NBN plans (particularly on FTTP — Fibre to the Premises connections) offer symmetrical speeds (same download and upload), which matters significantly for businesses uploading large files, running cloud backups, or hosting any services.
What Business NBN does NOT guarantee: Uncontended bandwidth. The NBN access network is shared infrastructure. Under heavy load (particularly on FTTN and HFC connections), speeds can vary from the rated maximum.
Enterprise Ethernet: What You Are Getting
Enterprise Ethernet (also called Layer 2 Ethernet, dedicated fibre, or business fibre) is a fundamentally different product. It uses dedicated fibre infrastructure — typically either fibre direct from an ISP’s network or via a Carrier Ethernet exchange — that is not shared with other customers.
Guaranteed, uncontended bandwidth: If you purchase a 100 Mbps symmetrical Enterprise Ethernet service, you get 100 Mbps symmetrical bandwidth available at all times — not subject to congestion from neighbouring businesses or residential users.
Symmetrical speeds as standard: Enterprise Ethernet services are almost always symmetrical — same upload and download speeds. This is critical for businesses with significant upload requirements (cloud services, video hosting, large file transfers to clients).
Stronger SLA: Enterprise Ethernet services typically carry an SLA with mean time to repair (MTTR) commitments of 4-8 hours, with financial rebates for SLA breaches. This is materially stronger than Business NBN fault restoration commitments.
Reliability: Dedicated infrastructure with a single provider’s SLA covering the entire path (rather than the shared nbn co access network) typically results in higher reliability and faster fault resolution.
Static IP addresses: Enterprise services typically include static IP addresses (often a block), which matters for businesses running servers, hosting services, or with VPN requirements.
Side-by-Side Comparison
| Feature | Business NBN | Enterprise Ethernet |
|---|---|---|
| Infrastructure | Shared (nbn co) | Dedicated fibre |
| Bandwidth | Up to rated speed (variable) | Guaranteed (uncontended) |
| Symmetry | Usually asymmetric (higher download) | Symmetrical as standard |
| Typical speeds | 100-1000 Mbps down / 20-50 Mbps up | 10-10,000 Mbps symmetrical |
| SLA | 8-12 business hours fault restoration | 4-8 hours, often with rebates |
| Static IP | Sometimes included | Standard |
| Price range | $80-250/month | $400-2,000+/month |
| Provisioning time | 5-20 business days | 30-90 business days |
Which Is Right for Your Business?
Business NBN Is Appropriate When:
- Your team is under 30 staff with standard cloud application usage (Microsoft 365, video calls, general web)
- Your primary connectivity use is outbound (staff accessing cloud services, browsing, Teams calls)
- You can tolerate occasional performance variation during peak periods
- Budget is a primary consideration
- The connection technology at your premises is FTTP (Fibre to the Premises) — this provides significantly better and more consistent performance than FTTN or HFC
Enterprise Ethernet Is Worth the Investment When:
- You have 30+ staff with heavy simultaneous cloud usage
- Upload bandwidth is critical (cloud backup, large file transfers, video production, serving applications to external users)
- Your business has hard uptime requirements (SaaS product, e-commerce, client-facing applications)
- You are running servers or services that external users access
- You need guaranteed performance for video conferencing at scale
- You are in a multi-tenancy building where NBN infrastructure may be congested
The Middle Ground: NBN + 4G/5G Failover
For many Melbourne SMBs, the right answer is Business NBN as primary connectivity with a 4G/5G failover connection providing continuity during primary connection outages. This provides reliability without the cost of Enterprise Ethernet, and is implemented easily with a dual-WAN router or SD-WAN appliance.
A 4G/5G backup connection on a SIM-only plan costs $50-100/month and eliminates the single point of failure risk for most businesses.
Availability in Melbourne
Enterprise Ethernet availability varies by location. In the Melbourne CBD and inner suburbs, multiple providers offer competitive fibre products. In outer suburbs and industrial areas, availability may be limited to a single provider at a higher price point.
