Much like its predecessors The Rovers and Barrier Reef, The Outsiders was predicated on the conceit that the central characters (Pete Jarrett and his grandfather Charlie Cole) were nomadic protagonists: travelling across Australia, they spent each episode in a new location with a new guest cast.
Moran, in his Guide to Australian TV Series, says of the concept that 'They are in effect fictional tourists, a perfect foil for a series that starred a German and a British actor in the lead roles, carried overseas as well as local crew, and British and German investment.'
A co-production with a German production company, The Outsiders had two non-Australian actors in the lead roles: German actor Sascha Hehn as Pete and Scottish actor Andrew Keir as Charlie. Don Storey, in his Classic Australian Television, notes that Hehn's dialogue was over-dubbed by Andrew Harwood, because Hehn's English was deemed to be too heavily accented. Storey concludes that
In most episodes, The Outsiders has a storyline that is effective in its simplicity. There is plenty of action and stunt work, but it's the interplay between the characters and the understated atmosphere of the series which gives it depth. Technically, the series is excellent, with superb camera work, skilful writing, good direction and competent acting. The only minor criticism is the dubbed voices of the German actors.
