Donald Fisher is a fictional character in the Australian television soap opera Home and Away played by actor Norman Coburn as a regular character, from the soap's inception in 1988 to 2003. He acts as the main antagonist in the show's pilot episode, willing to go to any lengths to ensure local teen Bobby Simpson is locked up, however his character soon softens. He spends almost his entire tenure on the show as the Principal of Summer Bay (at which he is given his iconic nickname "Flathead"), where he is stern but fair to all the students. Although departing as a main character in 2003, Coburn has since returned for brief appearances in 2004, 2005 and 2007. Coburn's long-running portrayal of Fisher earned him a place in the 2002 Guinness World Records alongside castmates Ray Meagher and Kate Ritchie. as the longest serving cast member of an Australian soap opera.
