What's the difference between a business NBN plan and a consumer NBN plan?

Business NBN plans are designed with higher priority traffic handling, dedicated support lines and features like static IP addresses. They also typically include service-level commitments and business-grade routing that consumer plans don't offer. Caznet's business NBN plans include all of these by default.

Is there a lock-in contract?

No. All Caznet Business NBN plans are available on flexible month-to-month terms. We also offer discounted rates on longer-term agreements if you prefer price certainty — just ask our team.

How long does setup take?

For most Adelaide premises, NBN activation takes 5–10 business days from order. If a technician visit is required (e.g. for a new connection), this may take a little longer. Caznet handles the entire process and keeps you updated throughout.

Can I get a static IP address?

Yes. Static IP addresses are available as an add-on on Caznet Business NBN plans. A static IP is useful for hosting services, VPN connectivity, remote monitoring and other business applications. Contact us to add one to your plan.

What happens if my NBN service goes down?

Call our Adelaide support team on 1300 229 638 or email caznet@caznet.com.au. We'll diagnose the issue and lodge a fault with NBN Co on your behalf. Business plans with Gold SLA have a 4-hour restoration target for qualifying NBN network faults — subject to NBN Co fault acceptance and standard exclusions.

How do I switch from my current internet provider?

Caznet handles the NBN transfer on your behalf — you don't need to contact your current provider first. Once you sign up, we submit the transfer request to NBN Co. Most businesses experience minimal downtime (typically under 30 minutes during the scheduled switchover). We'll keep you updated throughout the process.

What hardware do I need?

For most NBN connection types, you'll need a compatible business-grade router. Caznet can advise on suitable hardware for your connection type and business size. If you're upgrading from FTTN or HFC to FTTP, a new NTD (Network Termination Device) will be installed by an NBN technician as part of the upgrade process.

What NBN speed does my business actually need?

As a general guide: NBN 100/250 suits most businesses with 1–10 staff using email, video calls and cloud apps. NBN 500/1000 is appropriate for 10–30 staff or businesses with heavy cloud workloads and hosted VoIP. NBN 2000 or dedicated fibre is worth considering for 30+ staff or high-demand applications. When in doubt, call our team — we'll ask the right questions and recommend the best fit.

Need a higher tier of NBN, or something beyond it?

NBN Enterprise Ethernet delivers dedicated symmetric bandwidth with stronger SLAs — still on the NBN network but built for higher-demand businesses. For completely carrier-independent connectivity, dedicated fibre is also available.

Enterprise ethernet → Dedicated fibre →

All prices include GST. Speeds shown are maximum theoretical — actual speeds vary by location, connection type and network conditions. FTTP = Fibre to the Premises · FTTC/FTTB = Fibre to the Curb/Building · FTTN = Fibre to the Node · HFC = Hybrid Fibre Coaxial (cable). ~ indicates variable performance: the speed tier is technically available on that technology but actual speeds depend on line quality, distance and local conditions — the advertised speed is not guaranteed. Fixed Wireless is a separate access technology; availability and performance are subject to tower capacity and are assessed per address.

Free upgrade available

Could your business get free full fibre?

NBN Co is upgrading thousands of Adelaide premises from copper (FTTN) and cable (HFC) connections to full Fibre to the Premises (FTTP) — at no charge. FTTP unlocks much faster speeds, symmetric uploads and a more reliable connection.

Faster speeds

FTTP supports speeds up to 2 Gbps download and 500 Mbps upload — not possible on copper or HFC connections.

At no charge

Eligible premises can upgrade without any installation cost. NBN Co covers the infrastructure — you just need a compatible plan.

Better reliability

Fibre connections are not affected by distance from the node or weather — a material improvement over FTTN copper.

Gold SLA

What is the Gold SLA?

Some Caznet Business NBN plans include an Enhanced SLA — NBN Co's eSLA 4hr 24x7 product — giving your service priority fault resolution around the clock.

4hr

Restoration target

Where technically possible

24/7

365 days a year

Public holidays included

Priority queue

Escalated ahead of standard faults

FTTP only

Eligible connections

Not on HFC, FTTC/B, FTTN or Fixed Wireless

Standard SLA

–Up to 3 business days to restore

–Business hours support only

–Standard fault queue priority

Gold SLA

✓4-hour restoration target

✓24/7 — including public holidays

✓Priority escalation with NBN Co

Important — what the eSLA covers (and what it doesn't)

Target, not a guarantee

The 4-hour restoration time is a target set by NBN Co — not a contractual guarantee. The clock starts only after NBN Co formally accepts the fault as residing on their network, not from the moment the service drops.

Qualifying faults only

The eSLA applies only to faults confirmed within the NBN Co access network. It does not apply to faults caused by customer premises equipment, routers, internal cabling, building wiring, power failure at the premises, or issues in Caznet's own network.

Exclusions

Planned maintenance windows, emergency outages declared by NBN Co, force majeure events (storms, floods, natural disasters), and situations where physical site access cannot be obtained are all excluded from the eSLA clock.

Urban areas

All restoration targets assume an urban area. Regional or remote sites, or any site requiring a physical NBN Co technician visit, may have longer restoration windows that fall outside the standard target.

Optional add-ons

Enhance your NBN connection

Available on any Caznet Business NBN plan — just ask our team when you sign up or at any time.

Add-on

4G/5G Failover

Keep your business online if your NBN connection drops. A 4G or 5G SIM-based failover link automatically takes over when your primary service is unavailable — so your staff, EFTPOS terminals, VoIP phones and cloud apps stay running while the fault is resolved.

✓Automatic failover — no manual intervention

✓Ideal for businesses that can't afford downtime

✓Works alongside any NBN technology

Ask about failover →

Add-on

Static IP Address

A fixed public IP address assigned exclusively to your service. Essential for businesses running VPNs, remote desktop access, on-premises servers, security cameras, or any system that needs to be reliably reachable from outside your network.

✓Fixed address — does not change between sessions

✓Required for site-to-site and remote-access VPNs

✓Available on all Business NBN plans
