5G home broadband is increasingly being used as a replacement for NBN by people who work from home. It’s quick to set up, works without a technician, and in good coverage areas delivers speeds competitive with NBN 100. But is it actually a reliable choice for full-time WFH, or does the wireless nature cause problems? Here’s an honest look at 5G for working from home in Australia in 2026.
Short answer
If you have strong 5G coverage at your home and your work doesn’t require absolute uptime guarantees, 5G is a perfectly viable WFH option. It’s often faster than NBN 100, similar price, and a lot easier to set up. The main risks are indoor signal quality and occasional congestion-related dropouts.
What WFH actually needs from internet
Most home-office work doesn’t need crazy bandwidth. The actual requirements:
- Zoom HD video call — 3–4Mbps down, 3–4Mbps up
- Microsoft Teams HD — 2–4Mbps
- Google Meet HD — 3.2Mbps
- Webex — 2.5Mbps
- Screen sharing — 2–4Mbps additional
So a single person on a video call only needs about 5Mbps. The reason you’d want a faster plan is for everything else running at the same time — cloud sync, downloads, family members streaming, multiple video calls.
What 5G actually delivers
Real-world 5G home broadband performance in Australia:
- Speed — 100–400Mbps down, 20–50Mbps up
- Latency — 15–30ms typically
- Jitter — usually low but can spike during handoffs
- Packet loss — usually under 1%
All of those numbers are comfortably good enough for video calls, screen sharing and cloud-based work. In strong coverage, 5G actually outperforms NBN 100 for raw speed.
The three things that affect 5G WFH reliability
1. Indoor signal strength
This is the biggest variable. 5G works great with a clear line of sight to the tower, but it can struggle through:
- Thick concrete walls (apartments, basements)
- Metal-framed buildings
- Heavily insulated walls
- Distance from the nearest tower (especially over 2km)
Before committing to 5G for WFH, run a money-back trial. Telstra, Optus and TPG all let you return the modem within 30 days if signal is bad.
2. Evening and peak congestion
5G towers are shared. When lots of nearby users are online at the same time, speeds can dip. For WFH this is usually fine during business hours (most people are at work) but can show up during evening calls.
NBN has similar congestion issues with budget providers, but premium fixed-line plans are more predictable.
3. Brief dropouts during handoffs
5G modems occasionally hand off between towers or frequency bands. This can cause a 1–2 second blip in your connection — barely noticeable for most things, but enough to interrupt a video call momentarily.
NBN has fewer of these brief dropouts. For mission-critical video meetings, it’s worth having a backup connection (your phone’s mobile data can tether in a pinch).
5G vs NBN for WFH — direct comparison
| NBN (FTTP/HFC) | 5G Home Broadband | |
|---|---|---|
| Speed | 100–1000Mbps | 100–400Mbps typical |
| Reliability | Very high | Good but more variable |
| Setup time | 1–4 weeks for new install | Same day |
| Indoor signal | Not an issue | Can vary by location |
| Latency | 10–25ms | 15–30ms |
| Latency consistency | Very consistent | Mostly consistent |
| Backup options | 4G/5G phone tether | Different network tether |
| Cost | $59–$129/mo | $59–$99/mo |
Best practices for WFH on 5G
- Get a strong-signal location for the modem — near a window facing the nearest tower is usually best.
- Use Ethernet from the 5G modem to your work computer — eliminates Wi-Fi as a variable.
- Have a backup — your phone’s tethering or a $30/month prepaid data SIM as a backup for emergencies.
- Test before committing — Telstra, Optus and TPG all offer money-back trials. Use them.
- Watch peak congestion — if your area gets slow between 7–10pm, it’ll affect any after-hours calls.
When 5G doesn’t work for WFH
Skip 5G for WFH and stick with NBN if:
- You’re in a fringe coverage area or have poor indoor signal
- You’re a tech worker or remote IT support — you need extremely consistent uptime
- You do video production or upload large files daily
- Your job requires guaranteed bandwidth (legal/medical telehealth, trading desks, etc.)
- You have employer-mandated minimum bandwidth requirements
What about 4G home broadband for WFH?
4G is more widely available than 5G and is fine for WFH in good coverage. Expect 30–80Mbps with 25–50ms latency. Slower than 5G or NBN 100, but enough for video calls and normal office work. A solid backup option if 5G isn’t available at your address.
WFH 5G FAQ
Will my employer accept 5G as my work internet?
Most employers don’t dictate connection type, but they may have minimum speed and reliability requirements. Check your IT policy. If your job has strict uptime requirements, NBN is safer.
Can I claim 5G home broadband on tax?
If you use it for work, yes — you can claim the work-related portion just like NBN. Talk to your accountant for the specific calculation.
Does 5G get slower in the evening?
Sometimes, in busy areas. WFH is usually unaffected because peak congestion is in the evening, after work hours.
How does 5G compare to FTTN for WFH?
In good 5G coverage, 5G is much better than slow FTTN. If your FTTN delivers 30Mbps and your 5G delivers 200Mbps, the upgrade is genuine. If your FTTN delivers 90Mbps+ already, the difference is smaller.
Can I take my 5G modem when I travel?
Standard 5G home broadband modems are designed to stay at your registered address. Some Optus and TPG plans allow you to use them anywhere on the network. For full portability, look at portable 5G hotspots or Telstra’s “Move” plans.
