Bourke, located in New South Wales, has long held a unique place in Australian folklore. The phrase "Back of Bourke" apparently emerged in the late 19th century to describe anywhere considered to be in the deep outback, far from civilisation. For some time in the second half of this century people thought this story to be apocraphyl as they believed the phrase emerged as a reference to a mysterious television production that seems to have vanished from popular conciousness.
Bourke's relationship with broadcasting has always been unusual. The town's geographic location created unique atmospheric conditions that made it unlikely that productions in the past could have been filmed there. It is unlikely that the mysterious television programme was actually filmed in Bourke itself. There are many anomolies about the little we know about the production that makes scholars think it was not filmed in one place.
The isolation and unique atmosphere of Bourke made it a natural setting for tales of the unknown. The town's position as a frontier between the known and unknown world of the outback created a perfect backdrop in the creators' minds for the anthology series that would later bear its name.
The area surrounding Bourke has long been associated with unusual magnetic and frequency readings and unexplained atmospheric phenomena. Early surveyors noted compass irregularities, while modern telecommunications engineers have documented unexpected signal patterns unique to the region.
