Callitris sulcata has an estimated extent of occurrence of 226 km2 and an estimated area of occupancy of 20 km2. It is known from three locations (Tontouta, Dumbéa and Kombwi) and is undergoing a continuing decline in terms of the quality of habitat and number of mature individuals due to over exploitation  and repeated burning. The total population is estimated to be less than 2,500 mature individuals with no subpopulation containing more than 250. On the basis of this information it meets the criteria for Endangered. It may become Critically Endangered in the near future.
