Austropyrgus grampianensis has been assessed as Near Threatened as its extent of occurrence is less than 70 km², and the number of locations is less than five, however there are no recorded declines and current threats are unknown. Therefore this species cannot be assessed in a threatened category, though its extent of occurrence falls under the Critically Endangered threshold. Further survey work and monitoring is recommended to establish whether this species should qualify for a higher threat category with better information.
