NBN Internet
« Back to Glossary IndexIntroduction
Welcome to this expanded guide on NBN Internet, created for Australian business owners with teams of 20–250 staff. The National Broadband Network (NBN), managed by NBN Co Limited, is a transformative project by the Australian Government designed to modernize the country’s digital backbone. Through the nbn® network, businesses can access faster, more reliable internet connections, helping them leverage cloud solutions, improve collaboration, and close the digital divide. Understanding the different broadband technologies, speed tiers, and broadband plans is crucial when choosing the right internet service and long-term connectivity strategy for your business.
What Is the NBN?
- Definition: The National Broadband Network (NBN) is Australia’s wholesale-only broadband network. It was created to replace ageing copper lines and copper cable with fibre optic cables, satellite connections, and fixed wireless technologies.
- Purpose: To provide reliable, high-speed internet service to businesses and households across Australia, enabling essential applications such as streaming movies, online shopping, monitored fire alarms, fire alarm systems, lift phones, monitored security alarms, and VoIP carriage.
- Key Milestones:
- 2009: The NBN was first announced.
- 2010s: Initial construction and the nbn rollout began, with connections like Fibre to the Node (FTTN), Fibre to the Premises (FTTP), Fibre to the Curb (FTTC), and Fibre to the Building (FTTB).
- Ongoing: Upgrades such as Gigabit Passive Optical Network (GPON) and faster fibre network expansions are underway. The sale of NBN Co remains a future possibility debated at the federal level.
How Does NBN Work?
The NBN operates as a wholesale network. NBN Co builds and maintains infrastructure, while retail service providers (RSPs) or internet service providers (ISPs) deliver nbn® Plans to businesses and homes.
- NBN Co: Manages the infrastructure, including point of interconnect locations, distribution point units, and technologies such as nbn Fixed Wireless, nbn Satellite, and Sky Muster satellites.
- RSPs / Phone Companies: Offer broadband plans with options such as Unlimited Data, Typical evening speeds, and 4G Mobile Backup.
NBN Connection Types
The NBN employs a Multi-Technology Mix (MTM), giving businesses a range of internet connection types depending on location.
| Connection Type | Description | Typical Performance | Best For |
|---|---|---|---|
| FTTP (Fibre to the Premises) | Fibre optic cables directly to the premises | Fastest speeds, most reliable | Businesses future-proofing operations |
| FTTN (Fibre to the Node) | Fibre to a street node, copper wire into premises | Variable performance, distance-sensitive | Established suburbs |
| FTTB (Fibre to the Building) | Fibre to building comms room, copper to units | Stable, shared | Multi-dwelling offices |
| FTTC (Fibre to the Curb) | Fibre to a distribution point unit near premises, then copper | High speed, reliable | Suburban offices |
| HFC (Hybrid Fibre-Coaxial / HFC networks) | Uses pay-TV coaxial cable | High speeds, stable | Areas with legacy cable TV |
| Fixed Wireless (nbn Fixed Wireless) | Radio signal from nearby tower | Moderate, variable | Regional businesses |
| Satellite / Sky Muster / nbn™ Sky Muster™ Plus | Geostationary satellites delivering coverage | Slowest, higher latency | Remote/isolated premises |
Pros and Cons
- FTTP: Best long-term option, supports high broadband speeds and future upgrades.
- FTTN: Affordable, but performance impacted by ageing copper wire.
- HFC: Leverages existing HFC networks, good short-term option.
- Fixed Wireless/Satellite: Extends coverage to regional/remote areas, but affected by weather and congestion.
How to Get Connected
Businesses can follow these steps to connect to the nbn® network:
- Check Address: Use the NBN address checker to see if your premises are serviceable (known as premises passed).
- Choose an Internet Service Provider: Compare internet service providers based on customer service, price, and broadband performance.
- Select an Internet Plan: Decide between speed tiers (25, 50, 100, 250, or 1000 Mbps), Unlimited Data, or business-grade options.
- Book Installation: Some premises may require an NBN technician and a Network Termination Device.
- Set Up Equipment: Connect modem/routers (e.g. Optus Ultra WiFi Modem), Wi-Fi boosters (e.g. Optus Ultra WiFi Booster), and configure DHCP device settings.
NBN Speed Tiers
The NBN offers multiple speed tiers for different business needs:
- NBN 25 / 50: Suitable for small offices, emails, online shopping, and streaming movies.
- NBN 100 / 250: Best for larger businesses with multiple cloud applications.
- NBN 1000 (Max Speeds): Ideal for data-heavy industries, education networks, health care, and high-definition streaming.
Performance may vary depending on the internet connection type, Typical evening speeds, congestion, and in-office equipment (e.g. Wi-Fi routers with Band Steering, Single SSID, and 4G back-up).
Who Sells NBN?
The NBN operates on a wholesale model. Businesses must buy services from retail service providers (RSPs) such as Telstra, Optus, TPG, Vodafone, and smaller ISPs.
When choosing a provider, evaluate:
- Broadband plans: Price, Unlimited Data, bundled phone services (e.g. Unlimited Local Calls, Unlimited Standard National Calls, Big Talk, Oz Talk).
- Customer Service: 24/7 customer service, Customer Service Guarantee (CSG), or CSG Waiver agreements.
- Added Features: Business VoIP, 4G Alternative to nbn®, 5G Alternative to NBN, backup services, and smart bundling (e.g. Optus SubHub, Optus store support).
NBN vs Other Options
| Internet Type | Speed | Reliability | Availability | Cost |
|---|---|---|---|---|
| NBN | High | Very reliable | Nationwide | Varies |
| ADSL | Low | Poor | Being phased out | Cheap |
| Cable | Medium-high | Moderate reliability | Limited areas | Moderate |
| 5G / 4G Home Internet | High (variable) | Dependent on coverage | Urban-focused | Competitive |
Common Issues & Fixes
| Issue | Causes | Fix |
|---|---|---|
| Dropouts | Modem issues, line faults | Restart, check cabling, contact ISP |
| Slow Internet Speeds | Peak congestion, copper limitations | Use Ethernet, upgrade plan, optimise Wi-Fi |
| Installation Delays | Infrastructure or scheduling | Contact RSP/NBN Co |
