Main image

Three Hummock Island is an island in Tasmania, Australia, lying in Bass Strait off the north-west coast of the state. The island is sparsely populated and known locally for its coastal and rural character.

Low-density settlement, coastal scenery and natural shoreline are the main attractions; visitors typically arrive by private boat or charter and come for seascapes, birdlife and rural landscapes rather than formal tourist infrastructure.

European use of the island has been primarily for small-scale settlement and pastoral activities; the island has no major urban development and has retained a largely rural character.

Located off Tasmania’s north-west coast in Bass Strait, administratively part of the state of Tasmania and accessible only by sea or private craft.
