Residents in a series of coastal communities have been told it's too late to leave their properties as an out-of-control bushfire cuts evacuation routes.
An emergency warning is in place for parts of Wedge Island, Grey, Cervantes, Nambung and Cooljarloo in the Shire of Dandaragan in Western Australia.
It includes the coastal fishing villages of Wedge and Grey, about 170km north of Perth.
The blaze started on Monday and has burned through about 43000 hectares of bushland. (HANDOUT/DEPARTMENT OF FIRE AND EMERGENCY SERVICES WA)
