Need help on a tv show

Yesterday I was thinking about a show that I watched as a kid in the 80s, but I really can't remember the name. The premise of the show was a man being wrongfully sent out to the penal colony of Australia and his struggle to get home and clear his name. It may have been a series that had 6 or so episodes. Anyone got any ideas?I don't think I mixed it up with something else but after all these years who knows!
