5G Home Internet: The NBN Killer?
With mmWave technology rolling out in CBDs, 5G home internet is hitting speeds of 500Mbps+. Is it finally reliable enough to ditch the cable?
For years, 5G Home Internet was the "budget alternative"—good for renters, but bad for gamers due to lag. In 2026, the deployment of mmWave (millimeter wave) technology in Australian capital cities is changing the narrative.
Speed vs. Stability
Our latest tests in suburban Sydney and Melbourne show 5G plans from Telstra and Optus consistently hitting 300-500Mbps download speeds. That rivals NBN Superfast plans for a fraction of the price (typically $60-$70/month).
However, physics still applies. 5G signals struggle to penetrate double-brick walls, and "congestion" during the Netflix peak hour (7 PM - 9 PM) can see speeds drop by 40%.
Who Should Switch?
- Renters: No technician visits, no modem setup fees. Just plug and play.
- Solo/Couple Households: Perfect for 1-2 simultaneous streams.
- Budget Conscious: Savings of $240/year compared to NBN 50 plans.
Who Should Stay on NBN?
Gamers (ping is still higher on 5G), large families, and work-from-home pros who need bulletproof reliability for Zoom calls.
Read the Fair Use Policy Before You Switch
"Unlimited" 5G home internet plans are rarely unlimited in practice. Most carry a fair-use threshold (commonly somewhere in the 1-2TB/month range) after which your connection can be deprioritised during network congestion — meaning your speed drops specifically at peak times, which is exactly when you'd notice it most. Check the fair-use policy, not just the advertised price, especially if your household streams heavily across multiple devices.
Test at Your Actual Address Before Committing
5G home internet performance varies enormously by address — distance from the nearest tower, building materials (double brick and concrete apartment blocks are the worst case), and even which room you place the modem in all matter more than they do for a wired NBN connection. Most providers offer a trial period or money-back satisfaction guarantee specifically because performance is so address-dependent; use it. Don't cancel your existing NBN connection until you've verified real-world speeds at your address over at least a few days, including during the 7-9pm peak.
The Modem Matters More Than You'd Think
The router supplied with your plan is usually adequate, but placement — near a window, elevated, away from thick walls — can make a bigger difference to your actual speed than switching providers. If your first modem position gives disappointing results, try relocating it before assuming 5G isn't viable for your home.
Checklist for Action
- Audit your current bills: Gather your last 12 months of statements for Internet.
- Compare the market: Use SaveNest's comparison tools to identify the top 3 cheapest providers in your area.
- Check for loyalty taxes: Call your current provider and ask them to match the best offer you found online.
- Verify concessions: Ensure you are receiving all state and federal rebates you are entitled to.
- Set a reminder: Mark your calendar for a 6-month review to ensures you stay on the best plan.
- Share the savings: Tell a friend or family member how much you saved to help them avoid the 'lazy tax' too.
