Connectivity in Numbulwar: A Remote Link on the Gulf of Carpentaria
Numbulwar, a small Aboriginal community on the Gulf of Carpentaria in Australia's Northern Territory, is home to one submarine cable landing point. This cable, the
Groote Eylandt, connects Numbulwar to Alyangula, a town on Groote Eylandt itself, just 95 km away. While modest in scope compared to major hubs like Sydney or Darwin, this single cable plays a unique role in linking isolated communities in a region where access can be challenging.
The Groote Eylandt Cable: Stitching Together Remote Communities
The Groote Eylandt cable, operational since 2011, is entirely domestic, serving only Australian landing points. Its short length reflects its focused purpose: connecting Numbulwar to Alyangula, another remote community in the Northern Territory. Unlike cables in Sydney, which host international traffic across 10 separate systems, or Darwin, with its six cables, Numbulwar’s single connection is tailored to local needs. This is not a gateway to the world but a bridge between two isolated locations.
For Numbulwar, this cable is essential for maintaining communication with Alyangula and accessing broader networks through regional hubs. From Alyangula, data can travel onward to Darwin, which serves as a larger node in Australia’s cable infrastructure. Despite its modest scale, this connection ensures that Numbulwar remains part of the national telecommunications network.
Latency Measurements: A Window Into Performance
GeoCables' monitoring reveals an average round-trip latency of 265 ms for connections to Numbulwar, with the best observed latency at 0 ms. These figures reflect the challenges of serving remote areas, where distances and infrastructure limitations can impact performance. However, the cable remains a reliable link for the community, enabling essential services and communication.
A Community at the Edge
Numbulwar’s geographic and cultural isolation makes its connectivity story particularly compelling. The town, formerly known as Rose River Mission, is primarily inhabited by the Nunggubuyu people, who speak Wubuy and Kriol. Access to Numbulwar is restricted, requiring a permit from the Northern Land Council, which underscores its status as a closed community. In such a setting, the Groote Eylandt cable is more than just a piece of infrastructure-it is a thread tying Numbulwar to the outside world.
Positioning Numbulwar in Australia's Cable Landscape
Australia hosts 32 submarine cables across 27 landing points, with an average cable length of 6020 km. Numbulwar’s single 95 km cable is far shorter and less complex than the systems serving major cities like Sydney, Melbourne, and Perth. Yet, it ranks in the top 52% of Australian landing points by cable count, highlighting its importance in a sparsely connected region.
While Numbulwar may not boast the bustling connectivity of urban centers, its role in the Groote Eylandt cable chain is a reminder that even the most remote communities are part of Australia's broader telecommunications network. For Numbulwar, this connection is a quiet but significant lifeline to Alyangula and beyond.
