Business nbn & Fibre Access

TC-4 is the best-effort traffic class used by standard nbn plans: you get up to the plan's peak speed, download is faster than upload, and capacity is shared, so speeds can vary at busy times. TC-2 is a committed traffic class: a set amount of symmetric bandwidth, the same up and down, with nbn targets for delay, jitter and frame loss. Many businesses run both, using TC-4 for general internet and TC-2 for the traffic that must stay smooth, such as voice, video and site-to-site links.

nbn Enterprise Ethernet, often called TC-EE, is a dedicated fibre service with symmetrical wholesale speed tiers up to nearly 10 Gbps, a choice of High, Medium or Low class of service, a 99.95% network availability target and 24/7 support. It suits head offices, data-heavy sites, multi-site networks and anything you host on site. nbn quotes it as available to about 1.6 million business locations.

Many can. In eligible areas, premises on FTTN or FTTC can move to FTTP when they order an eligible higher speed plan, with nbn installing its own equipment at no charge to the provider (some providers pass on other costs). For a business-grade installation nbn also asks for a qualifying product such as nbn Business Service. We check your address, confirm eligibility and handle the order and installation day.

nbn's business speed tiers come with nbn Business Service: Essentials carries a 12 hour fault restoration target and Pro a 4 hour target, both supported 24 hours a day, 365 days a year. nbn also offers optional enhanced service levels, named Enhanced-12, Enhanced-8, Enhanced-6 and Enhanced-4, each in a business hours (7am to 9pm) or 24/7 version. Enterprise Ethernet includes 24/7 support with fast fault restoration.

You need one if anything has to find your site from the internet: a VPN that staff or other offices connect to, a phone system or camera system reached from outside, a server you host, or a supplier that only accepts connections from known addresses. A static IP stays the same, so firewall rules and allow-lists keep working. We include static addressing where you need it and can provide a block of addresses for larger sites.

With a second path that takes over automatically. For most offices that is a 4G or 5G service on the same managed router, which fails over in seconds and keeps cloud apps, payments and calls running. Larger sites add a second fixed service over a physically separate path, and those with their own address space run BGP across both, so inbound services keep working too.

It depends on the technology and what is already in the building. Where an nbn service is already in place, a new business service can often be live within days. A full fibre upgrade or a new fibre lead-in takes longer because nbn may need to build to the premises, and for Enterprise Ethernet nbn commits to design and build new fibre in most business locations in its fixed line footprint within 50 business days. We give you a realistic date once the address is qualified.

nbn's business wholesale tiers are Business 100 Essentials (100/40 Mbps), Business 250 Essentials (250/100 Mbps), Business 500 Pro (500/200 Mbps), Business ~1000 Pro (about 1000/400 Mbps) and Business 2000 Pro (2000/500 Mbps). The Pro tiers need FTTP, 250 Essentials needs FTTP or HFC, and 100 Essentials is available on every fixed line technology. Enterprise Ethernet goes further, with symmetric tiers up to nearly 10 Gbps.

Yes, and it makes a strong one. A Starlink dish reaches the internet through satellites in low earth orbit, so it shares no cable, pit, exchange or tower with the fixed service it protects. We connect it to the same managed router or SD-WAN appliance as the nbn or fibre link, so traffic moves across automatically if the fixed service has a fault and moves back once it is restored. For sites that must stay online we often pair it with 4G/5G as well, giving three independent paths.

Starlink is a separate service from SpaceX, delivered from its own constellation of low earth orbit satellites and ordered directly rather than through the nbn. Its business Local Priority plans include priority data, a public IP address, prioritised 24/7 support and a 99.9% network availability service level. Sky Muster is nbn's geostationary satellite service for premises outside its fixed line and fixed wireless footprint. nbn withdrew its Business Satellite Service at the end of 2025 and expects to begin moving Sky Muster customers to its own low earth orbit service from around mid-2027.
