Confused by business internet options in Melbourne? Compare NBN, Fibre, and 5G plans to find the best speed and reliability for your office.
Choosing a business internet plan in Melbourne is more complex than selecting the fastest available speed at the lowest price. The right plan depends on your connection technology, team usage patterns, uptime requirements, and the quality difference between providers on your specific infrastructure.
This guide gives you the information to make an informed decision — without the sales-speak.
The Three Options Available to Melbourne Businesses
1. Business NBN
What it is: Internet service delivered over the nbn co network — the government-built national broadband infrastructure. Almost all Melbourne addresses are NBN-connected. Business NBN plans differ from residential plans in speed tiers, SLA commitments, and traffic management.
Speed tiers available (dependent on connection technology at your address):
- NBN 25 (25 Mbps down / 5-10 Mbps up) — minimum viable for small teams
- NBN 50 (50/20 Mbps) — suitable for 5-10 staff with moderate use
- NBN 100 (100/20 Mbps) — suitable for 10-20 staff
- NBN 250 (250/25 Mbps) — suitable for 20-40 staff
- NBN 1000 (1000/50 Mbps) — available on FTTP connections, suitable for 40+ staff
What differentiates Business NBN from residential:
- Priority traffic management during congestion periods
- Faster fault restoration SLA (typically 8-12 business hours vs best efforts on residential)
- Business hours support access
- Static IP address (important for VPN and remote access)
- ABN billing with proper tax invoices
Monthly cost range: $80-$250/month depending on speed tier and provider.
2. Enterprise Ethernet (Dedicated Fibre)
What it is: A dedicated fibre connection (not shared NBN infrastructure) from the provider’s network to your premises. Provides guaranteed, uncontended bandwidth.
When it makes sense:
- More than 40+ staff with heavy cloud usage
- High upload requirements (cloud hosting, video production, serving external users)
- Hard uptime requirements with financial penalty for downtime
- You need symmetrical speeds (same upload and download)
Typical specifications: 100 Mbps symmetrical to 10 Gbps symmetrical. Speeds are guaranteed — not “up to.”
Monthly cost range: $400-2,000+/month depending on speed, location, and provider. Provisioning lead time: 30-90 business days.
Availability: Widely available in Melbourne CBD and inner suburbs. Variable in outer suburbs and industrial areas. Check availability before committing to a lease.
3. Fixed Wireless / 5G Business Internet
What it is: Internet connectivity delivered via 4G or 5G mobile networks to a fixed antenna at your premises. Available from Telstra, Optus, and several smaller providers.
When it makes sense:
- Business NBN is unavailable or inadequate (particularly for FTTN addresses with poor copper)
- A backup connection for primary NBN or fibre
- Temporary connectivity (new office fit-out before NBN is provisioned)
- Remote or regional premises not served by NBN
Performance: 5G fixed wireless provides 100-300+ Mbps download in areas with strong 5G coverage. Upload is typically 20-50 Mbps. Subject to radio congestion during peak periods.
Monthly cost range: $80-200/month for 5G business plans. Hardware (5G antenna/gateway): $200-600 as capital purchase or included in contract.
The Provider Comparison
Not all NBN plans are equal even at the same speed tier. Providers purchase wholesale capacity from nbn co and the quality of their network management determines the real-world performance you experience.
CVC (Connectivity Virtual Circuit) congestion — the bottleneck between your NBN connection and the broader internet — varies significantly between providers. Cheaper providers may be under-provisioned and congested during peak periods (8-10am and 5-8pm).
Recommended providers for Melbourne business NBN (based on independent testing and industry feedback):
- Aussie Broadband Business — consistently rated highly for real-world performance and customer service. Transparent about their CVC provisioning.
- Superloop — strong performance, competitive pricing.
- Telstra Business — premium pricing, strongest SLA commitments, largest network.
- Optus Business — solid middle-tier option with mobile bundling advantages.
Providers to approach cautiously for business use: Some budget providers underperform at peak times. Check independent performance testing (nbn’s regular performance reports) before committing.
The Decision Framework
Under 10 staff, light cloud use: NBN 100/20 from a quality provider. Cost: ~$100-120/month.
10-20 staff, moderate Teams and Microsoft 365 use: NBN 250/25 on FTTP or HFC, or NBN 100/20 with 4G/5G failover. Cost: ~$130-180/month.
20-40 staff, heavy video conferencing and cloud backup: NBN 1000/50 (FTTP required) or consider Enterprise Ethernet for symmetrical upload. Cost: $150-500/month.
40+ staff or high uptime requirement: Enterprise Ethernet 100/100 Mbps to 500/500 Mbps. Cost: $500-1,500/month.
Reliability requirement (any size): Add a 4G/5G backup connection to any primary plan. Cost: add $60-100/month for a reliable backup.
Negotiating Your Contract
Business internet contracts are typically 12-24 months. Before signing:
- Confirm the SLA and what remedies apply if fault restoration exceeds the committed timeframe
- Confirm whether installation costs are included or additional
- Confirm static IP is included (important for VPN and remote access configurations)
- Confirm whether hardware (modem/router) is supplied or needs to be purchased
- Ask about early termination fee — circumstances change
