What NAB investment holdings does
NABIH describes itself as a provider of telecommunications infrastructure and data‑centre management, offering wholesale voice and data services across Australia and New Zealand.
Under “Voice,” the company maintains interconnects to multiple Tier‑1 carriers, enabling partner firms to reach major networks — ensuring stable, high‑quality voice connectivity.
On the “Data” side, NABIH claims access to both major and niche last‑mile access networks throughout Australia. This breadth allows the company to offer robust, bandwidth‑intensive solutions, regardless of customer location or access method.
The company also operates a Tier‑3 data centre in Western Sydney, offering colocation, hosting and managed services. Through that facility, NABIH supports business‑critical and disaster‑recovery workloads — an important capability in a region where reliable infrastructure is increasingly in demand.
According to its site, NABIH maintains presence or coverage through partner facilities and networks in major Australian cities such as Sydney, Melbourne, Brisbane and Perth, in order to ensure broad reliability and flexibility for clients.
The company’s publicly listed autonomous system number confirms its role as a registered network operator / Local Internet Registry (LIR) in the APNIC region, responsible for routing and IP‑prefix management.

Why NABIH matters in Australia’s telecom landscape
As demand for digital services — cloud, VoIP, hosting, colocation — rises across Australia, smaller infrastructure providers such as NABIH help diversify the market beyond the large national carriers. A Tier‑3 data centre, wholesale voice and data capability, and access to multiple backbone and last‑mile networks give NABIH the flexibility and reliability needed by businesses, ISPs, or resellers seeking scalable, carrier‑neutral solutions.
Given that many Australian companies now rely on cloud services, remote work, and high-availability hosting, having local, reliable data‑centre infrastructure lowers latency and risk compared with distant international hosting. NABIH’s colocation and managed services offering could be especially attractive to businesses with regulatory, compliance or privacy requirements.
However, the industry also faces challenges: competition from major international cloud providers, pressure on margin from wholesale competition, and the need to continuously invest in network upgrades and data‑centre resilience. For smaller players like NABIH, success likely depends on maintaining network neutrality, offering flexibility, and delivering reliable connectivity — particularly for niche customers underserved by the big providers.
In this context, NABIH represents a valuable middle‑tier supplier: bridging global backbone providers, local networks and business clients, and helping ensure that Australia’s digital infrastructure remains diverse, resilient and accessible.
