The film was the idea of director Peter Maxwell. It was originally intended to be set on
Hayman Island but Reg Ansett, who had interests on the island at the time, was not keen on showing a robbery on the island. It was made with funding from Greater Union, the
Queensland Film Corporation and
Australian Film Commission. Shooting began in November 1979 with a month's worth of filming at
Maroochydore and
Noosa Heads, and eight weeks of night shooting in
Sydney. Scenes set on a
Great Barrier Reef island were shot at a Maroochydore hotel. Its original shooting title was
Friday the 13th but this was changed when the horror movie with the same name came out. ==Release==
