NBN vs Enterprise Ethernet: Which Is Right for Your Business?

One of the most common questions we get from clients is whether they should stick with NBN or invest in enterprise-grade ethernet. The answer depends on how critical internet connectivity is to your business operations.

After 25 years of connecting Sydney businesses, here's our honest comparison.

NBN: The Basics

NBN (National Broadband Network) is Australia's wholesale broadband network. It's affordable, widely available, and sufficient for many small businesses. Plans range from 50Mbps to 1Gbps depending on your technology type and provider.

The key limitation of NBN is that it's a shared network — your speed can vary during peak times, and service level agreements (SLAs) are limited. If your connection goes down, restoration can take days.

Enterprise Ethernet: The Difference

Enterprise ethernet (also called business-grade fibre) provides a dedicated connection with guaranteed bandwidth, symmetrical upload and download speeds, and strict SLAs — typically with 4-hour restoration guarantees.

• Guaranteed symmetrical speeds (e.g., 100/100Mbps, 1000/1000Mbps)
• 99.95%+ uptime SLAs with financial penalties for breaches
• 4-hour fault restoration guarantees
• No contention — the bandwidth is exclusively yours
• Priority support and dedicated account management

When NBN Is Enough

For many small businesses — especially those without cloud-dependent applications or VoIP — NBN provides excellent value. If a day of internet downtime would be inconvenient but not catastrophic, NBN is likely the right choice.

We recommend NBN Enterprise Ethernet (a step up from standard NBN with better SLAs) as a middle ground for businesses that need more reliability without the full cost of dedicated fibre.

When You Need Enterprise Ethernet

Consider enterprise ethernet if any of these apply:

• Your business loses significant revenue for every hour of internet downtime
• You rely heavily on cloud applications, VoIP, or video conferencing
• You need guaranteed upload speeds for large file transfers or hosting
• You have compliance requirements for connectivity uptime
• You operate multiple sites connected via SD-WAN or MPLS

The Cost Reality

Enterprise ethernet typically costs 3-10x more than an equivalent NBN plan. For a 100Mbps symmetrical connection, expect to pay $500-$1,500 per month depending on your location and contract term.

But consider the cost of downtime. If your business generates $10,000 per day in revenue and you lose two days of connectivity per year on NBN that would have been resolved in four hours on enterprise ethernet, the maths often favours the upgrade.

We help businesses find the right connectivity solution. Whether it's NBN, enterprise ethernet, or a combination with failover, we'll design a solution that matches your needs and budget.
