Phoenix Five is an Australian science fiction television series which first screened on the ABC in 1970. It was later also screened on the Seven Network. It was part of a trilogy and followed on from the six part serial The Interpretaris in 1966 and seven part serial Vega 4 in 1968. However, it had 26 standalone episodes produced to make it viable as a syndicated series. Each of the series had different crews and casts but took place in the same future and used the same space organisation and miniatures, much as Star Trek did in the '80s and '90s, thus making it the first TV sci-fi franchise.
