Syzygium austrocaledonicum is an endemic small tree or shrub of New Caledonia largely distributed from the south to the north west of Grande Terre as well as in Belep islands. It occurs in humid forest and shrubland on soils derived from ultramafic and volcano sedimentary rocks from 10-900 m asl. With an extent of occurrence (EOO) and area of occupancy (AOO) respectively equal to 16,848 and 308 km², this species is a common species and does not seem threathened. Therefore, S. austrocaledonicum is considered as Least Concern (LC).
