Searching for the top 10 cheapest NBN plans Australia?
Australia 2026 are facing a confusing market full of “6-month special deals”, temporary discounts, and complicated pricing. While some internet providers advertise very low introductory prices, the true cost over 12 or 24 months can be significantly higher once promotional pricing expires.
That’s why smart shoppers are now comparing:
- Real long-term pricing
- Typical evening speeds
- Australian-based customer support
- Network reliability
- No lock-in flexibility
- Availability across all NBN technologies
Here’s a comparison of the widely advertised cheapest NBN plans Australia from major providers in Australia, including the true long-term pricing where available.
| Provider | Cheapest Advertised Plan | Introductory Price | Ongoing Price | 12-Month Cost | 24-Month Cost | Notes |
|---|---|---|---|---|---|---|
| Cmobile | Economy 20/2 | $59 | $59 | $708 | $1,416 | Extra $5/month off with mobile bundle |
| Telstra | Basic NBN 25 | ~$89 | ~$89 | ~$1,068 | ~$2,136 | Premium pricing with modem & 4G backup |
| Optus | NBN 25 | $79 | $79 | $948 | $1,896 | Higher cost than many competitors |
| TPG | NBN 25 | ~$54.99 | ~$69.99 | ~$749 | ~$1,589 | Heavy focus on first-year discounts |
| Aussie Broadband | Basic NBN 25 | ~$75 | ~$75 | ~$900 | ~$1,800 | Strong Aussie support reputation |
| Superloop | NBN 25 | ~$59 | ~$69 | ~$768 | ~$1,596 | Often includes 6-month promos |
| Tangerine Telecom | Value NBN 25 | $44.90 | $69.90 | $689.40 | $1,528.80 | Large 6-month discount promotion |
| MATE Communicate | Crikey NBN 25 | ~$65 | ~$65 | ~$780 | ~$1,560 | Australian support focus |
Why Cmobile Stands Out
While some providers advertise lower short-term pricing, Cmobile focuses on:
- Low everyday pricing
- No lock-in contracts
- Australian-based customer support
- Nationwide access across all NBN technologies
- Fibre, Fixed Wireless and Satellite services
- Additional savings through mobile bundling
Importantly, Cmobile’s pricing remains consistent rather than increasing sharply after a promotional period.
For households wanting predictable internet costs without “promo pricing surprises”, Cmobile’s cheapest NBN plans Australia offer strong long-term value in 2026.
Customers can also save even more by bundling with any Cmobile mobile plan and receiving an additional $5/month discount on their NBN service.
At Cmobile, customers benefit from:
- Low everyday pricing instead of short-term promo gimmicks
- Australian-based support
- Access to all major NBN technologies nationwide
- Fibre, Fixed Wireless and Satellite options
- Bundle discounts when combined with a Cmobile mobile service
Cmobile’s standout entry-level offer is the NBN 20/2 Economy Plan for just $59/month, and eligible customers can save an additional $5/month by bundling with any Cmobile mobile plan.
Why Introductory NBN Deals Can Be Misleading
Many large providers advertise:
- “$20 off for 6 months”
- “Special new customer pricing”
- “Save for the first year”
But after the promotional period ends, prices usually jump substantially. Over 24 months, some “cheap” deals actually end up costing hundreds more than providers with stable everyday pricing.
For example:
- Tangerine heavily promotes 6-month discounts.
- TPG markets a “Price Beat Guarantee” based on first-year pricing only.
- Telstra, Optus and other premium providers often remain among the most expensive long-term options.
