Heard & McDonald Islands

A small natural anchorage on the north-eastern coast of Heard Island, sheltered by volcanic headlands, historically used as a landing site for scientific expeditions to the island.

A broad bay on the eastern coast of Heard Island, bordered by volcanic cliffs and glaciers, with a shoreline that reflects the ongoing interaction between volcanic activity and glacial erosion.

A distinctive peninsula forming the northernmost projection of Heard Island, composed of volcanic rock and bounded by dramatic cliffs, offering views of the island's central volcano from a perspective unavailable elsewhere.

An active volcanic peak on Heard Island, rising to 2,745 m from the Southern Ocean, with glaciers that descend directly into the sea and lava flows that periodically reshape the coastline.

A group of small sub-Antarctic islands about 45 kilometres west of Heard Island, consisting of McDonald Island, Flat Island, and Meyer Rock, with McDonald Island itself hosting an active volcano that erupted in 1997 and 1999.

A shallow coastal lagoon on the eastern side of Heard Island, formed where glacial meltwater collects behind a barrier of volcanic sand and gravel before flowing into the Southern Ocean.
