Address Unknown was an Australian radio show also known for a while as the Colgate Show and The Caltex show, after the sponsors of the show .

Address Unknown dramatized real-life cases of missing persons in order to help the Missing Person's Bureau find people and close case files.  The hopes were that a listener might hear some details and know who or where the person was and call in.  Although it is unknown how many cases the show actually solved, Address Unknown certainly made great radio dramas!
