The beach at Midge Point was significantly eroded after Cyclone Debbie in 2017. In response, The beach was reprofiled using sand taken from a shallow burrow within the tidal zone which was pushed up to the scarf. Sand was removed at a maximum rate of 5m3 per meter of beach. Additionally, fencing was installed to prevent vehicle access, and the dune area was revegetated.
