3CX VOIP in Cairns: Pricing, Porting & Setup — The Practical Migration Guide
6 October 2025The quick answer
- In town with FTTP/HFC: NBN 500/750/1000 (if available) gives best price–performance.
- Remote/regional with patchy copper: Starlink is a strong primary link; pair with 4G/5G failover. Median latency continues to improve.
- Mission-critical uptime: Consider Enterprise Ethernet or dual-WAN (e.g., NBN FTTP + Starlink/5G) with automatic failover.
What the NBN speed upgrades mean (2025)
NBN has accelerated its higher speed tiers and multi-gig options for eligible FTTP/HFC premises, lifting the ceiling for SMEs that move big files or run cloud apps all day. This is great news for Teams/SharePoint heavy users and VOIP quality.
Typical tiers you’ll see
- NBN 100 / 250 — solid for most offices.
- NBN 500 / 750 / 1000 / 2000 — where FTTP/HFC allows, these tiers now have much better value and evening speeds.
Starlink for FNQ sites (pros/cons)
Pros: High throughput, quick to deploy, ideal for agriculture, tourism lodges and remote depots.
Cons: Latency higher than fibre; weather can affect performance; needs clear sky. Latency has dropped materially in the last two years and continues trending down.
4G/5G as primary or failover
Great as a backup link, or a primary link for pop-up sites. Mind the data caps and the building’s indoor coverage. External antennas help.
VOIP and internet quality (practical)
- Aim for jitter < 20ms, packet loss < 1% for clear 3CX calls.
- Avoid CG-NAT on your SIP trunk unless your VOIP provider supports it.
- QoS on the router for voice VLANs.

A simple decision path
- Check your address for FTTP/HFC eligibility (ask about the FTTP upgrade program). If FTTP/HFC available, go NBN 250+ if you have 10+ staff or heavy cloud apps.
- If only FTTN/Fixed Wireless, weigh Starlink as primary + 4G/5G failover.
- If outages hurt you, add dual-WAN with automated failover and monitor both links.
- If compliance or uptime is strict, consider Enterprise Ethernet or a fibre service.
Router & network checklist
- Dual-WAN, QoS, VLANs, SIP-friendly NAT
- Business-grade Wi-Fi with roaming
- UPS for modem/router/switch
- Proactive monitoring and alerts
FAQs
Can Starlink replace NBN in town? It can, but if you can get FTTP/HFC, fibre is still lower latency and often cheaper per Mbps.
What speed do I really need? 10–15 staff with Teams/SharePoint do fine on NBN 250; heavy file sync or creative teams benefit from 500+.
How long does fibre take to install? Weeks to months depending on civils and lead-in.
