In 1978, Sedge Island was owned by Walter "Wally" McBeth, who tried to settle there with his wife and two daughters. He planned to build a small airstrip for FIGAS but this did not happen. He did however set up an unsuccessful sheep farm, first with a hut that he floated onto the island, and then a prefabricated house, which has three bedrooms.

In 1985, it was acquired by David Hawksworth, who has owned it ever since.
