Creator James Davern originally wrote and submitted the pilot for a Network Ten National Scriptwriting Contest in 1979. It came third, and earned him a merit award. (After the series concluded its original 1981-93 run on the Seven Network, Ten would produce one final season in 1994.) Before Seven Network handed over the series to Ten, they wrote into the timeline a massive, catastrophic bush fire that sacked and razed the entire township to the ground. The characters that were not killed in the fire, agreed to abandon "Wandin Valley", effectively killing the entire series. Why Network Seven did this, and why or how ownership of the very successful television series was handed over to TEN remains unclear to this day. This author supposes that greed was a decisive factor.
The episode where Molly Jones dies of cancer was one of the highest rating in the series history. Although the rating system of the day was antiquated, the episode rated in the high thirties, which equates to more than a thirty percent share of all prime time viewing, across five free to air networks - in U.S. terms, roughly equivalent to an episode of Charlie's Angels (1976) at the height of its popularity. It dominated newspaper front pages of the day, and is still one of the most discussed episodes of Australian television.
