Your internet connection underpins almost everything your business does - video calls, cloud software, file sharing, and payments. Yet most Perth small businesses are running on residential NBN plans that weren't designed for business use. Here's what you need to know.
Business NBN vs Residential NBN - What's the Difference?
Residential NBN plans are designed for home use, where occasional slowdowns are an inconvenience. Business NBN plans come with a Service Level Agreement (SLA) that guarantees fault response times - typically within 4–8 hours versus the next business day (or longer) for residential faults. For a Perth business, an afternoon without internet can mean thousands in lost productivity.
Business plans also often include symmetrical speeds - equal upload and download. This matters if your team is constantly uploading large files, backing up to the cloud, or running video calls, where upload speed is just as important as download.
NBN Connection Types in Perth - Which Do You Have?
What speeds are possible for your premises depends on how you're connected to the NBN. The main types are:
- Fibre to the Premises (FTTP) - the best option. Pure fibre all the way to your building. Supports very high speeds and is the most reliable.
- Fibre to the Node (FTTN) - fibre runs to a street cabinet, then existing copper runs to your premises. Speed and reliability degrades the further you are from the node. Very common in older Perth suburbs.
- Fibre to the Curb (FTTC) - better than FTTN, with fibre reaching closer to the building. More stable than FTTN.
- Hybrid Fibre Coaxial (HFC) - uses the old cable TV network for the last stretch. Performance varies by area and time of day.
If you're on FTTN and experiencing speed issues, an upgrade to FTTP may be available - NBN Co has been progressively upgrading Perth premises.
How Much Speed Does a Perth Business Actually Need?
A rough guide based on concurrent users:
- 1–5 staff: 50/20 Mbps is usually adequate for general office use
- 5–15 staff: 100/20 Mbps or higher, especially if using cloud-heavy tools like Microsoft 365
- 15+ staff or heavy cloud use: 250/25 Mbps or a dedicated business fibre service
These are guides only - the real answer depends on what your team does. A graphic design firm uploading large files needs much more upload capacity than a retail shop processing card payments.
Should You Consider a Backup Connection?
For any Perth business where internet downtime means lost revenue, a 4G/5G backup connection is worth the modest monthly cost. When your primary NBN goes down, the backup kicks in automatically. This is especially important for businesses running cloud-based point-of-sale, VoIP phone systems, or remote teams.
Don't Forget the Router
Even the best NBN plan performs poorly through a consumer-grade router not designed for business traffic. A proper business-grade router with quality-of-service (QoS) settings ensures your video calls and business applications get priority over less critical traffic on the same network.
What to Do If Your NBN Is Underperforming
If your Perth business is experiencing slow speeds, frequent dropouts, or unreliable connections, the issue may not be your plan - it could be your router, internal network cabling, or NBN equipment that needs attention. A proper network assessment can pinpoint the cause before you spend money on a plan upgrade you don't need.
If you're outside the Perth metro NBN footprint altogether - common across the Wheatbelt, South West, Great Southern, and Mid West - the NBN may not be the right starting question at all. See our guide on Starlink for Business in Regional WA for when a satellite connection makes more sense.
Frequently Asked Questions
What's the real difference between business and residential NBN plans?
Business plans come with a Service Level Agreement that guarantees fault response times, typically within 4-8 business hours compared to next business day or longer for residential faults. They also often include symmetrical upload and download speeds, which matters if your team is regularly uploading files or on video calls.
How much NBN speed does my business actually need?
As a rough guide, 50/20 Mbps is usually fine for one to five staff doing general office work, while businesses with 5-15 staff on cloud-heavy tools like Microsoft 365 typically want 100/20 Mbps or more. The real answer depends on what your team actually does, a business uploading large files needs more than one just processing card payments.
Is it worth having a backup internet connection?
For any business where an internet outage means lost revenue, a 4G or 5G backup connection that kicks in automatically is worth the modest monthly cost. It matters most if you're running cloud-based point of sale, VoIP phones, or a remote team that can't just switch to paper for the afternoon.
Our NBN speed test looks fine but things still feel slow, what's going on?
The bottleneck often isn't the NBN plan itself but the router or internal network. A consumer-grade router without proper quality-of-service settings can let one device hog bandwidth and slow everything else down, so a network assessment is usually a better first step than paying for a plan upgrade.
A business-grade router and correctly configured network get more out of your NBN connection than any plan upgrade.
