Authorities in Western Australia are both concerned and confused following the haunting discovery of a seemingly-abandoned 'SOS' sign in a remote part of the country.
The eerie distress call was noticed by a helicopter pilot as he flew over the area last week and subsequently reported the oddity to police.
An investigation into the case has proven to be rather difficult as the site is so secluded that authorities were forced to enlist the help of a helicopter company to bring them there as the location was otherwise inaccessible.
Upon arriving, police found evidence of a campfire, although they were uncertain of how old it might be, but no indication of anyone in the area.
