How fast is NBN Internet and does speed depend on my address?

NBN Internet speeds depend on the type of NBN connection available at your address, such as Fibre to the Premises (FTTP), Fibre to the Node (FTTN) or Hybrid Fibre Coaxial (HFC). Some locations can access speeds up to 1000Mbps, while others may have lower maximum speeds based on line quality and network technology.

Which NBN plan speed is right for my business?

The right NBN Internet speed depends on how your business uses the internet. Smaller teams handling email and browsing may suit lower speed tiers, while businesses using cloud software, VoIP phones, video conferencing or large file transfers often benefit from higher speed plans such as 100Mbps, 250Mbps or above.

NBN Internet FAQs

Answering your questions

What is “NBN Internet” in Australia?

NBN Internet refers to internet services delivered over the nationwide network operated by NBN Co. It uses a mix of technologies fibre, hybrid-fibre coaxial, fixed-wireless or satellite to connect homes and businesses. The network replaces the old copper-based system to provide faster, more reliable internet.

How fast is NBN — and does speed depend on my address?

NBN speed depends on your connection type (e.g. FTTP, FTTN, HFC). Fibre-to-the-premises (FTTP) tends to deliver the fastest and most reliable speeds up to 1 Gbps or more for residential/business customers.

Some other connection types (e.g. FTTN or HFC) may offer lower or variable speeds depending on line quality and network congestion.

Which NBN plan speed is right for my small business?

It depends on how your business uses the internet.

Basic use (emails, web, light browsing): 25/10 Mbps or 50/20 Mbps may suffice.
Everyday business use (cloud-based apps, VoIP, video calls): 100/40 Mbps or 250/100 Mbps are a safer bet.
High usage (multiple users, large data transfers, simultaneous video conferencing, cloud backups): 500/200 Mbps or even 1000/400
Mbps ideal for larger small businesses or teams working remotely.

Why choose Comsource for NBN rather than a large telco?

Comsource specialises in small and medium business needs, offers personalised Australian-based support, and can bundle NBN with business phone systems (cloud PBX, softphone, SIP trunks).
You also get secure data centres in Australia, which helps with compliance and data sovereignty.

Can I get backup internet or fallback if NBN goes down?

Yes, Comsource offers 4G Backup (or 4G services) as a complementary / fallback option.
This can be highly valuable for businesses that rely on uninterrupted internet (VoIP phones, cloud services, remote work).

How do I know if NBN is available at my address?

On the Comsource NBN page there is an “Enter your address” field to check what NBN connection (if any) is available at your location.
If NBN is not available, Comsource’s support team can advise whether upcoming upgrades or alternative services may suit you.

Is there a risk that NBN connection speed will drop below what’s advertised?

Yes, actual speed depends on the technology type (FTTP, FTTN, HFC etc.) and on the quality of the existing line. For example, customers on FTTN may not achieve the full speed of a higher-tier plan if their line is degraded.
That’s why it’s important to check the “maximum attainable speed” for your address and consider what your business actually needs.

Can I combine NBN with cloud phone systems and VoIP?

Yes, one of the advantages of using Comsource is that their NBN plans are designed for business usage, including VoIP, cloud PBX, remote working and phone-system bundles.
This makes it easier for businesses to manage internet + phone services in a single streamlined package.
