Boat Harbour, TAS, Australia: Submarine Cable Landing Point

Boat Harbour is a coastal location in Tasmania, Australia, and serves as a submarine cable landing point connecting Tasmania to the Australian mainland. One submarine cable lands here, establishing a direct undersea link between two parts of Australian territory across the Bass Strait. As Tasmania is an island state separated from mainland Australia by the Bass Strait, this landing point forms part of the inter-island domestic connectivity that ties the state into the broader Australian telecommunications network.

The single cable landing at Boat Harbour, Bass Strait-1, represents an entirely domestic connection, with both endpoints located within Australia. This makes Boat Harbour a landing point serving an intra-national corridor rather than an international or intercontinental one. Despite its modest scale in terms of cable count, its geographic role as a Tasmanian terminus of a Bass Strait crossing gives it a distinct character among Australian landing points.

Cables Landing at Boat Harbour

Bass Strait-1 is the submarine cable landing at Boat Harbour. It has a length of 241 kilometres and reached ready-for-service status in 1995. Both endpoints of Bass Strait-1 are located within Australia, making it a domestic submarine cable. The cable spans the Bass Strait, the body of water separating Tasmania from mainland Australia, and at 241 kilometres reflects the relatively short crossing distance involved in linking the island state to the continent.

Regional Context

Australia hosts 31 submarine cables across 27 landing points, and Boat Harbour, with one cable, ranks in the top 63 percent of Australian landing points by cable count. Major Australian hubs such as Sydney (10 cables), Darwin and Perth (5 cables each), and Melbourne (3 cables) handle considerably larger volumes of submarine cable infrastructure. Boat Harbour is a specialised domestic landing point rather than a multi-cable international hub, reflecting Tasmania's connectivity requirements rather than high-volume intercontinental traffic.

Network Role

Boat Harbour functions as a single-cable terminus, hosting the Bass Strait-1 cable and enabling an undersea link between Tasmania and mainland Australia. The cable's entirely domestic character means this landing point contributes specifically to intra-Australian connectivity across the Bass Strait corridor. With a 241-kilometre route and a ready-for-service date of 1995, Bass Strait-1 represents one of Australia's earlier submarine cable deployments.

As a one-cable landing point in a national network of 31 cables, Boat Harbour occupies a focused position within the Australian submarine cable graph, serving as Tasmania's dedicated Bass Strait crossing point rather than a node in international or multi-directional routing.
