The Unggarranggu spoke a Worrorran language. What little is known of it was taken down by Howard Coate in the 1960s.[2]
Country
The Unggarranggu by Norman Tindale's estimate had a domain extending over roughly 1,000 square kilometres (400 sq mi), ranging from the northeastern area of King Sound, the eastern side of Stokes Bay, and reaching north as far as Crawford Bay. They also were present on Helpman Island and those islands of the eastern part of the sound as far as Caffarelli. Their continental extension ran no more than 16 kilometres (10 mi) inland.[3]
Society
The Unggarranggu were basically a coastal people dwelling on the mainland, but were on close terms with the more maritime Umiida. Like the Umiida they plied rafts fashioned from mangrove woods, with which they would sail out to places like the island of Wilima off the mouth of Meda River, close to Warrwa territory.[3]
