Thursday Island and the Torres Strait: Australia’s Northern Frontier

Thursday Island is as far north as Australia goes before the sea takes over entirely. The island sits in the Torres Strait — the stretch of shallow, island-scattered water between Queensland and Papua New Guinea — in a part of Australia that feels removed from the rest of the country in ways that are partly geographic and substantially cultural.

I came here for the first time on a research trip connected to reef monitoring work in the northern Coral Sea, and I stayed longer than I’d planned. The island has a quality of isolation that is genuinely different from anywhere else in Queensland.

The Torres Strait

The strait is shallow — rarely more than 15 metres deep — and scattered with islands and reefs that have been inhabited by the Torres Strait Islander peoples for at least 4,000 years. The culture that developed here, maritime and connected to the reef in the most direct sense possible, is distinct from both Aboriginal mainland culture and from the Pacific Island cultures to the north.

The pearl diving history of Thursday Island — from the 1870s through to the mid-20th century decline — brought Japanese, Malay, Pacific Islander, and Filipino divers to the strait, and the multicultural community that resulted gives Thursday Island a demographic character unlike anywhere else in Australia. The Thursday Island cemetery, with graves from a dozen nationalities spanning every decade since the 1870s, is a remarkable record of the dangerous industry that built the town.

Diving the Torres Strait

The diving in the Torres Strait is extraordinary and almost entirely inaccessible to recreational visitors. There are no dive operators running regular trips from Thursday Island, and the infrastructure for visiting divers simply doesn’t exist as it does in Cairns or Port Douglas.

For the diver willing to make independent arrangements — bringing their own equipment, connecting with local knowledge about conditions and sites — the strait offers diving on pristine reefs with minimal diver traffic, in waters where species diversity begins to reflect the proximity to the Coral Triangle. A small number of specialist liveaboard operators include Torres Strait sites on extended expeditions from Cairns.

Getting There

Thursday Island is accessible by air from Cairns (one hour by Qantaslink, several times daily) or by ferry from the tip of Cape York. The island has accommodation at the Gateway Torres Strait Resort and a handful of smaller options.

For reef visitors specifically, Thursday Island is not a practical reef destination but a remarkable place that gives context to what the reef becomes at its northern edge — where Queensland becomes Papua New Guinea and the ocean connects Australia to the rest of the Coral Triangle.
