The 1966 Westall UFO Mass Sighting: Analysis of Declassified Australian National Archives and Intelligence Records

The Daylight Encounter

On the morning of April 6, 1966, one of the most significant mass sightings in Australian history occurred at Westall High School in Clayton South, Victoria. At approximately 11:00 AM, during a morning break, over 200 students and staff observed three metallic, disc-shaped objects maneuvering silently in the sky. Witnesses described the primary object as being roughly twice the size of a standard automobile, possessing a silver-grey luster and a slightly translucent quality. The weather was clear with high visibility, and the objects remained in view for approximately 20 minutes.

Physical Evidence and Military Response

The objects reportedly descended into a nearby paddock known as 'The Grange,' where one craft was seen hovering or landing for several minutes before ascending at high speed toward the northwest. Following the departure of the objects, students who rushed to the site reported finding a large area of flattened grass with a distinct circular 'burn' or swirl pattern. Witnesses further alleged that within hours, the area was cordoned off by unidentified personnel in military uniforms and civilian suits, who purportedly removed soil samples and instructed school staff and students to remain silent about the event. Historical testimony from science teacher Andrew Greenwood suggested that the objects were pursued by five unidentified aircraft during the encounter.

Declassified Documentation

For decades, the Australian government maintained that no official records of the incident existed. However, FOIA requests to the National Archives of Australia (NAA) and research into Project Blue Book archives have uncovered Department of Supply and RAAF intelligence files (specifically Series A703, File 580/1/1) that discuss 'unusual sightings' and aerial phenomena in the Clayton area. These records suggest that the incident was monitored by the Directorate of Air Force Intelligence (DAFI). Further declassified summaries from the 2020s indicate that official investigations into the radiation levels at the landing site were conducted by the Victorian State Emergency Service, though the final laboratory findings remain largely missing from public files.

Historical Significance

The Westall sighting is notable for its high number of independent, credible witnesses and the consistency of their descriptions across multiple decades. Unlike many UAP cases which occur at night and involve single witnesses, this was a broad-daylight encounter with significant duration, making it a cornerstone of international UAP research and a primary example of historical mass observation of non-conventional craft.
