An exclusion zone has been put in place on a Mid North Coast beach after a dead humpback whale washed up.
It is understood that the whale washed up on Big Hill Beach, near Crescent Head.
Witnesses say that the whale has inflated to triple it's size in recent hours.
Lifeguards on the scene have set up a drone to monitor shark activity in the area.
The exclusion zone has been set up as a precaution in case it explodes.
