Vanderlin covers 264 square kilometres, the biggest of the Pellew Islands by a wide margin. Its size is matched by its depth in time. Archaeologists led by Robin Sim excavated sites here and on neighbouring Centre Island and found evidence of human occupation reaching back roughly eight thousand years, across distinct phases as sea levels rose and the coastline settled into its present shape. This is not a place people merely visited. It is the traditional country of the Yanyuwa, the saltwater people of this Gulf — and within that country it belongs to the Walu, whose ties to these shores run through the whole sweep of the island's long human story.

For centuries, the Pellew Islands sat on a trade route that linked northern Australia to Asia. Each year, with the monsoon winds, fishermen from Macassar in Sulawesi sailed down to harvest trepang — the sea cucumber prized in Chinese cooking — and they kept coming until early in the twentieth century. They left their mark on these islands in stone fireplaces, scattered artefacts, and tamarind trees that grew from the seeds in their discarded meals and still stand today. The Yanyuwa traded and worked alongside these visitors, and the contact threads through the region's songs and memory — proof that this remote-seeming coast was, for a very long time, anything but cut off.

Today Vanderlin's people live in family outstations strung along the western shore — Mooloowa, Babungi, Yulbara and Uguie, from north to south. These are small places by design, each typically home to a handful of people, and the island's whole population has hovered around twenty. By 2019 it had narrowed to a single family of five, the Smiths, keeping presence on an island that has known thousands of years of it. The outstation movement that brought families back to country like this was about exactly that: not numbers, but presence — the right and the responsibility to live on, and care for, the land that holds your story. That right was not handed over freely. In 1977 the Yanyuwa lodged the first land claim in the nation under the new Aboriginal Land Rights Act, over Borroloola and these islands, and the long legal road that followed eventually returned the Pellew country to its people.

To understand why people stay, look to the water. The shallows around Vanderlin and its neighbours hold seagrass beds that feed dugong and sea turtle, the animals at the centre of Yanyuwa sea-hunting culture and song. The Dugong Hunter songline runs through these waters, and the skill of the maranja — the master hunters — was the skill of reading this exact sea. That knowledge lives in a language as remarkable as the country it describes: Yanyuwa is one of the very few languages on Earth with separate forms for men and women, distinct down to the grammar. The island that an explorer mistook for the mainland turns out to be one of the most storied places on the whole Gulf coast — a Dutch name on a map, an Asian trade route along its shores, and beneath it all an unbroken Aboriginal presence reaching back to a time when the coastline itself was still finding its edge.
