A Western Australia Department of Mines and Petroleum (DMP) report has identified that migrating sand dunes, up to 4 km wide and 20 m high, pose potential threats to roads, homes and infrastructure in the State’s Mid West.

While the report – Migration of Limesand Dunes in Western Australia and Their Impacts – has just been released, the information has already been presented to a number of State and Local Government agencies.

DMP Project Manager Mike Freeman, a key contributor to the report, has stressed that mobile dunes move very slowly over many years, but could cause serious problems if not monitored and kept in check.

DMP has presented the information and engaged with Local Government authorities in the Mid West, including the Shires of Gingin, Dandaragan, Coorow, Carnamah and Irwin, and the City of Greater Geraldton.
