The island is roughly crescent-shaped, and has an area of 2 km2 (0.77 sq mi). It lies to the northeast of the group's main island, Antipodes Island, separated from it by a 1.2 kilometre wide strait. The smaller Archway Island lies immediately to the northwest of Bollons Island.
Bollons Island is dominated by a curved ridge running the length of the island, with a highest point 202 metres (663 ft) above sea level. Cliffs surround the island on all sides except the west.
History
The island is named after John Bollons, Master of the New Zealand Marine Department vessels, NZGSS Hinemoa and SS Tutanekai.
