Gigabit internet — 1,000 Mbps download — is genuinely impressive technology. It's also the kind of headline speed figure that gets thrown around in marketing without much explanation of who actually needs it. For most Adelaide businesses, the question isn't whether gigabit sounds good. It's whether the extra investment translates into a real, observable difference for your team on a typical working day.
The answer depends far less on the headline number and far more on how your team works — how many people are connecting, what applications they're running, and how much of your workload involves pushing large amounts of data in and out of the office.
What gigabit internet actually means in practice
1 Gbps equals 1,000 Mbps. To give that figure some texture: at that speed, a 1 GB file transfers in roughly 8 seconds. A large video project file of 10 GB takes about 80 seconds. Your entire team could be running high-definition video calls, syncing files to SharePoint, pulling database backups, and streaming video simultaneously — and the connection would still have capacity to spare.
In practical terms, gigabit internet means bandwidth is never your bottleneck, no matter what your team is doing. The constraint moves elsewhere — to server performance, application architecture, or the speed of the internet services you're connecting to — rather than sitting at the edge of your premises.
NBN 1000 (Business) plans require either an FTTP or HFC connection. If you're on FTTN, you can't access gigabit speeds regardless of what plan you're on — the copper segment is the limiting factor. An FTTP upgrade changes that. See our Business NBN page for available speed tiers.
When gigabit genuinely makes sense
There are specific business profiles where moving to NBN 1000 is a straightforward decision rather than a luxury.
Large teams with concurrent heavy usage are the obvious case. If you have 50 or more staff all doing cloud-intensive work simultaneously — Microsoft 365, Salesforce, video conferencing, remote desktop, cloud-hosted applications — 250 Mbps or even 500 Mbps can become genuinely constrained during peak periods. Gigabit gives you headroom to grow without hitting the ceiling.
Businesses that regularly transfer very large files — video production companies, engineering and architecture firms working with large CAD models, businesses running large database backups to cloud storage — benefit significantly from high upload speeds. NBN 1000 Business delivers 400 Mbps upload alongside 1,000 Mbps download, which is a meaningful difference for organisations pushing large volumes of data out of the office.
Education campuses, medical imaging facilities, and businesses running on-premises servers that integrate with cloud platforms are also strong candidates. These environments have sustained, concurrent high-bandwidth requirements that lower tiers can't comfortably accommodate.
Finally, there's the headroom argument. If you're currently on NBN 250 and finding that peak-hour performance has noticeable dips as your team grows, moving to NBN 1000 before you're genuinely constrained is sensible planning rather than overspending.
When gigabit is overkill for your business
A business with 10 staff running Microsoft 365, attending video calls, using cloud-based accounting software, and sending emails does not need gigabit internet. NBN 250 Business — or even NBN 100 for a small team — comfortably handles those workloads with capacity to spare. The money spent on a gigabit plan above what you need is money that could go elsewhere.
Our speed guide on the NBN page maps typical staff counts to recommended speed tiers, which gives a starting point for the right-sizing conversation. The guide is based on typical office workloads — if your team is unusually bandwidth-intensive for your size, or unusually light, the actual recommendation might differ.
What about symmetrical gigabit?
NBN 1000 Business provides 1,000 Mbps download and 400 Mbps upload — impressive, but not symmetric. The upload speed is 40% of the download, which reflects NBN's shared infrastructure architecture.
If your business genuinely needs equal upload and download capacity — large-scale cloud backups, live video broadcast, off-site rendering, or high-volume data transfer between sites — symmetric gigabit requires a different solution. NBN Enterprise Ethernet offers symmetric speed options, and dedicated carrier fibre can be configured to whatever symmetric speed your operation demands. These are genuinely different products from standard Business NBN, with different pricing and contracting — but they're the right answer for operations where upload performance is equally critical to download.
Beyond gigabit
For completeness: NBN 2000 (2 Gbps download, 500 Mbps upload) is available on FTTP connections, bringing headline download speeds into territory that was enterprise-only territory just a few years ago. For businesses that need more than standard gigabit — and there are real use cases at the high end — NBN Enterprise Ethernet and dedicated carrier fibre circuits go well beyond this, supporting committed speeds from 250 Mbps up to multiple tens of gigabits for the right environment.
