Main image

Tasman Island is a small island off the south-eastern coast of Tasmania, Australia, notable for its lighthouse and steep sea-cliff coastline. The island sits within Tasman National Park and is an important site for marine wildlife.

From boats or authorised viewpoints on the Tasman Peninsula, visitors can view the island’s tall cliffs and the historic lighthouse structure. The island supports seabird colonies and is a visually prominent feature of the coastal landscape.

A lighthouse was built on the island in the early 20th century to guide shipping around the peninsula’s hazardous coasts; operations later moved to automated systems. The island has been managed as part of the national park to protect its natural values.

Tasman Island lies off the Tasman Peninsula near Port Arthur on Tasmania’s southeast coast and is commonly seen from sightseeing boat routes along the peninsula’s cliffs.

  • Access restrictions: The island lies within Tasman National Park and is remote; public access is restricted and usually limited to boat approaches or authorised visits.
  • Viewing: The island's coastal cliffs rise steeply and are among the features that attract sightseeing boat tours from the Tasman Peninsula.

What to See #

  • Tasman Island Lighthouse: A masonry lighthouse erected on the island that served as a manned navigational light through much of the 20th century.
  • Sea cliffs and wildlife habitat: Sheer coastal cliffs and offshore rock shelves that form nesting and haul-out habitat for seabirds and marine mammals and make landing difficult.
