Brisbane, QLD, Australia: Submarine Cable Landing Point

Brisbane is the capital city of Queensland and the third-most populous city in Australia, situated on the Brisbane River near Moreton Bay on the country's east coast. As a landing point for submarine cable infrastructure, Brisbane connects Australia into a regional corridor spanning Southeast Asia and the Pacific. One submarine cable lands at Brisbane, linking Australia northward through the archipelagos and island nations of Southeast Asia and the southwestern Pacific.

The cable landing at Brisbane is part of the Hawaiki Nui 1 system, a project that extends connectivity across a corridor reaching from Singapore through Indonesia and Timor-Leste, continuing to Papua New Guinea and the Solomon Islands, as well as multiple points in Australia. This route positions Brisbane as a node in a network that bridges both the Southeast Asian maritime region and the smaller Pacific island nations that have historically had limited subsea cable access.

Cables Landing at Brisbane, QLD, Australia

Hawaiki Nui 1 is a submarine cable system approximately 10,000 kilometres in length, with a scheduled ready-for-service date of 2027 and currently at draft status. The cable connects Australia, Indonesia, Papua New Guinea, Singapore, Solomon Islands, and Timor-Leste. Brisbane represents one of the Australian landing points on this system, placing Queensland's capital directly on a multi-country trans-regional cable route for the first time.

Regional Context

Within Australia's submarine cable landscape, Brisbane currently hosts one cable landing, placing it behind Sydney, NSW, which serves eight cables, and Darwin, NT, which serves four. Brisbane is comparable in cable count to Alexandria, Brookvale, Maroochydore, and Perth, each of which also host two or fewer cable landings. Notably, Maroochydore in Queensland also serves as a landing point, meaning Queensland will host two landing locations once Hawaiki Nui 1 reaches its ready-for-service date.

Network Role

Brisbane's role in the submarine cable graph is that of a single-cable terminus, anchoring one end of the Hawaiki Nui 1 system on Australia's eastern seaboard. The cable's reach across six countries enables Brisbane to participate in a corridor that connects the relatively well-served Singapore and Indonesian hubs with smaller, less-connected nations such as the Solomon Islands and Timor-Leste, as well as Papua New Guinea.

While Brisbane does not yet carry the volume of cable landings seen at Sydney, the arrival of Hawaiki Nui 1 establishes Queensland's capital as a distinct point of entry for international submarine cable traffic on Australia's east coast. In the broader regional submarine cable graph, this adds geographic diversity to Australia's international connectivity by extending cable infrastructure beyond the heavily concentrated New South Wales landing cluster.
