Linua has a length of 2.8 km and diameter of 1 km.[3]
The estimated terrain elevation above sea level is 23 meters.[4] Linua lies about 60 miles (100 km) north of Espiritu Santo Island between islands of Tegua and Lo. The island is surrounded by coral reefs. There is an airstrip on the island[5] opened in 1983 that provides the only regular transportation flights with the rest of Vanuatu.
The island is used mostly in times of plane landing, and is not settled permanently; the people there are based in the neighbouring village of Lungharegi, on Lo island. Linua has a small tourist hamlet, Kamilisa, consisting of four bungalows and a capacity of up to 20 people.
