The Kroombit tinker frog is confined to a very small area, consisting of nine fragmented rainforest patches over 500 metres altitude, with a total area of approximately 200 hectares, at Kroombit Tops, southwest of Gladstone, Queensland, Australia. Within the rainforest patches populations are associated with drainage lines and seepage areas. All sites on the Kroombit Tableland which are considered suitable for this species have been surveyed at least once during the species’ calling season, therefore it is thought that all existing populations in this region are known.
