NBN Enterprise Ethernet plans — Adelaide
Pricing shown is for 36-month agreements, ex GST. CBD zone pricing shown — Non-CBD zones are approximately $115/mth higher. 12 and 24-month terms available on request (POA). All services subject to site qualification.
Low Class of Service is the standard tier for most internet workloads — web browsing, cloud applications, email and general business connectivity. No frame delay or jitter guarantees are specified; the service uses available capacity on the EE network. This is what the plan cards above are priced on, and what most businesses need.
High Class of Service provides strict performance parameters: frame delay under 5.25 ms, jitter under 1 ms, and frame loss below 0.01%. This makes it suitable for real-time voice (VoIP), MPLS circuits, synchronous storage replication, and dedicated office-to-data-centre connectivity where latency variation would cause application issues. Priced higher than Low CoS.

Support tiers, eSLA & service availability
Every NBN Enterprise Ethernet plan includes a formal support tier. Your tier determines the eSLA restoration target and whether a Service Availability Guarantee (SAG) applies — both set by NBN Co.
The eSLA and SAG apply only to faults confirmed within the NBN Co access network. Faults caused by customer premises equipment, routers, internal cabling, building wiring, or power failure at the premises are excluded.
Planned maintenance windows and emergency outages declared by NBN Co are excluded from the eSLA clock and SAG calculations — regardless of duration.
Storms, floods, natural disasters, and any event outside NBN Co's reasonable control are excluded. Situations where a technician cannot gain physical access to the premises are also excluded from the clock.
The eSLA and SAG are targets set and administered by NBN Co. While they carry financial remedies for qualifying breaches, they are not unconditional service guarantees — Caznet passes through NBN Co's eSLA commitment to you as the end customer.
What's delivered to your premises
NBN Enterprise Ethernet is provisioned on true enterprise fibre access infrastructure. Here are the key technical characteristics of the service.
Class of Service (CoS) — performance characteristics
| Metric | High CoS | Low CoS |
|---|---|---|
| Frame Delay (ms) | <5.25 ms | Not specified |
| Inter Frame Delay Variation (ms) | <1 ms | Not specified |
| Frame Loss Ratio (%) | <0.01% | Not specified |
Reference distance 200 km. High CoS pricing is higher — see full pricing breakdown above. Low CoS is the standard tier.
NBN Enterprise Ethernet built for Adelaide business
NBN Enterprise Ethernet delivers a fundamentally different level of service to standard NBN. Here's what you get with Caznet.

Uptime SAG on Gold
Gold support targets 99.95% service availability, with financial rebates available when that target is breached on qualifying faults — subject to exclusions.
4-hour fault response on Gold
Gold support (included on 500 Mbps and above) targets a 4-hour 24/7 eSLA response for qualifying NBN network faults — right for mission-critical sites.

NBN Enterprise Ethernet — common questions
-
NBN Enterprise Ethernet (EE) is a premium NBN product that delivers dedicated, end-to-end fibre connectivity with symmetric speeds from 250 Mbps up to 10 Gbps. Unlike standard NBN plans, NBN Enterprise Ethernet runs on a separate NBN layer designed specifically for high-demand business users, with formal support SLAs and optional service availability guarantees.
-
A symmetric connection has identical speeds for uploads and downloads. This matters for businesses using cloud applications, video conferencing, VoIP, off-site backups and hosted servers — all of which require significant upload bandwidth that standard NBN plans can't deliver.
-
The SAG (Service Availability Guarantee) is a 99.95% monthly uptime target included with Gold support. When that target is breached by a qualifying fault, service rebates apply — 20% of the monthly fee up to 50% depending on the extent of the breach. Gold is included on 500 Mbps and above, and is available as an add-on ($149/mth) on the 250 Mbps tier. Bronze (included on 250 Mbps) does not include a SAG. The SAG applies to qualifying faults on the NBN Co network only — exclusions include planned maintenance, force majeure events, power failure at the premises, customer equipment and internal cabling faults, and situations where site access cannot be obtained.
-
Standard NBN Business uses a shared access network with asymmetric speeds and best-effort delivery. NBN Enterprise Ethernet uses a dedicated NBN layer with symmetric speeds, formal eSLA response time targets and an optional SAG. It's the right choice when connectivity is mission-critical and downtime has a direct business cost.
-
NBN Enterprise Ethernet requires a site qualification (SQ) by NBN Co before an order can be placed. The SQ confirms that the infrastructure required to deliver the service to your premises exists or can be built. In some cases a feasibility study is required for failed SQs. Caznet manages this process on your behalf — contact us to get started.
-
Setup is $0 on 36-month agreements. On 12-month agreements a setup fee applies — contact us for details. Fibre build costs are absorbed in most cases; however, sites requiring significant civil works may incur additional charges. Caznet will advise you of any costs after the site qualification is completed. Once ordered, delivery typically takes 50–90 business days from order acceptance to activation.
