Documents that have just become available under the 30-year rule at the National Archives of Australia reveal how two RAAF Mirage jets were placed on the second highest level of alert to determine the cause of unidentified radar contacts seen on screens at Mascot.
Other files, which can be viewed in Canberra, also give details of other unexplained sightings, some of which are supported by witness statements to police.
The only photographs in the Australian “X Files” is of unusual lights over Bendigo, witnessed by hundreds in May 1983. An interim report by the RAAF stated that Mike Evans, a 17-year-old disc jockey with the Bendigo radio station 3BO, received calls from listeners, then saw the lights himself and took photos.
One anonymous caller to the RAAF said the lights were caused by a rock group experimenting with laser lighting. The report said they were probably caused by train headlights or lasers or from planets or stars. There had been unusual weather atmospherics on the night.
