The major threats are unknown.

Given the declines of high-altitude stream-breeding species in other parts of the wet tropics, surveys are urgently needed to relocate this species and to assess its status, especially in view of the lack of recent records. Some other Cycloramphus species have declined for unexplained reasons, and so it is an urgent priority to rediscover populations of this species.

Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements.
