Most Australian households are paying $20–$40 per month more than necessary for their NBN plan. That's $240–$480 per year - real money that could be redirected to savings, investing, or paying off debt faster.
This guide focuses specifically on NBN: why cheap providers are just as good as expensive ones, which providers offer the best value in 2026, and exactly how to switch without a gap in service.
Why Cheap NBN Providers Are Often Just as Good
Here's what most people don't know: NBN Co wholesales access to all retailers at essentially the same prices. Optus, Telstra, and a small budget provider all pay NBN Co similar wholesale rates for the infrastructure - the copper or fibre connecting your home to the network.
The differences in end-user experience come down to:
CVC (Connectivity Virtual Circuit) capacity: Each provider purchases a finite amount of capacity from NBN Co to carry traffic between the NBN network and their own network. Under-provisioned CVC = slow evening speeds. Well-provisioned CVC = smooth, fast evenings even when the whole street is streaming.
Customer service quality
Margin: Budget providers take a smaller margin. Better value passes to you.
Independent testing (ACCC Measuring Broadband Australia reports, Ookla) consistently shows budget and mid-tier providers like Aussie Broadband, Mate, and Superloop outperforming or matching Telstra and Optus on real-world speeds - particularly during peak hours.
CVC Congestion Explained
When your internet slows down at 7–9pm, CVC congestion is usually the cause. Your provider hasn't bought enough "pipe" capacity from NBN Co to handle all their customers downloading and streaming simultaneously.
Telcos balance CVC cost against customer experience. Some cheap providers get this badly wrong; others (Aussie Broadband in particular) have built their brand on being transparent about CVC investment.
The fix if you're experiencing congestion:
- Run a speed test at 10am (off-peak) vs 8pm (peak). If there's a dramatic difference, congestion is likely.
- Contact your provider and ask about their CVC provisioning.
- If unsatisfied, switch. With no-contract plans, you can leave immediately.

How to Switch NBN Providers Without Downtime
Switching is simpler than most people expect:
Step 1: Choose your new provider and sign up online. Most sign-up processes take under 10 minutes.
Step 2: Your new provider contacts NBN Co to arrange the switch. This is done electronically.
Step 3: You'll receive a confirmed switch date - typically 2–10 business days after signup.
Step 4: On switch day, your new provider activates your service. In most cases, you simply reboot your modem and reconnect. No technician required.
Step 5: Your old provider sends a final bill for the days up to the switch date. No penalty fees on no-contract plans.
The overlap myth: You will not be without internet during the switch. The cutover is typically seamless - or at most involves a brief 30-minute reconnection window on the switch day.
Evening Speeds: The Metric That Actually Matters
Don't be misled by "maximum speed" figures. An NBN 100 plan theoretically offers 100Mbps downloads - but on a congested network, you might get 20Mbps at 8pm.
The ACCC's Measuring Broadband Australia reports publish typical busy period download speeds for major providers on each tier. These figures are far more useful than marketing claims. Search "ACCC Measuring Broadband Australia 2026" for the latest data.
Rule of thumb: if a provider's measured evening speed is within 75–90% of the plan's maximum speed, their CVC provisioning is solid.
Do You Still Need a Landline Phone?
Most Australians who bundle a phone line with their NBN plan rarely use it. In 2026, a mobile phone has replaced the landline for 99% of households.
Exceptions where a landline still makes sense:
- Medical alarms or personal emergency response systems (some require a copper phone line)
- Some older business EFTPOS systems
- Fax (rare but some businesses still use it)
For everyone else: drop the landline bundle, save $5–$15/month.
Modem Compatibility Checklist
Before switching, verify:
- Your modem is compatible with your new provider's network (most modern NBN modems are)
- Your modem supports the correct NBN connection type for your address (FTTN/FTTC/FTTP/HFC)
- Check the NBN Co modem checker at nbnco.com.au for your specific address type
If you need a new modem, factor this into your switching decision. A $150 one-off modem purchase is recouped within 4–6 months versus paying a $30/month modem rental.
The $20–$40/Month Opportunity
If you're currently with a major telco (Telstra, Optus, iiNet on older plans), you're almost certainly paying more than necessary. A 5-minute comparison exercise can reveal $20–$40/month in savings with no reduction in service quality.
$30/month saved = $360/year. Over 3 years = $1,080 - more than enough for a holiday, a new appliance, or a meaningful addition to your investment portfolio.
