coral island group, dependency of the French overseas country of New Caledonia, southwestern Pacific Ocean. With a total area of 160 acres (65 hectares), Huon comprises four islets—Huon, Leleizour, Fabre, and Surprise—each about 0.5 mile (1 km) in diameter. The Huon group lies within the D'Entrecasteaux barrier reef extending north of the main island of New Caledonia. The islands were once worked for guano. There are no permanent inhabitants.
