This Australian TV show was made for children by the ABC, originally adapted from the science fiction novel of the same name by British writer Louise Lawrence. Many well known Australian TV actors made their first appearances in the show.
I saw Andra on television as a kid and the show had a significant impact on me at the time. The poignant story of the future Andra juxtaposed with a child from the 1980's was quite innovative. I imagine it would look impossibly primitive by modern television standards, but for the era of 1970's TV it was an excellent and thought provoking piece on a future society gone wrong. It would make an ideal premise for a modern series.
