TULLY.
“On the morning of January 19, 1966, banana grower George Pedley was driving his tractor through cane country south of Tully in far north Queensland when he heard a hissing sound and saw a grey saucer-shaped object rise from Horseshoe Lagoon, a small swamp on a neighbour's property.”
Local police, Royal Australian Air Force investigators, and journalists arrived in the days that followed. RAAF officers documented and photographed the trace, and additional smaller "nests" of similar pattern were located on nearby properties. The reeds in the central nest had been broken at root level, and the swirl pattern was consistent enough across multiple sites that simple wind effects were ruled out by RAAF meteorologists. The official RAAF report listed the case as unexplained.
The Tully event is considered the foundational Australian crop-circle-style trace case, predating the famous English crop circle phenomenon by more than a decade. Skeptical hypotheses, including waterspouts and willy-willies, have been advanced. The Bureau of Meteorology examined the local weather record and found no support for either. Pedley, who had no interest in publicity and continued farming the area for decades, never altered his account.
The case is unusual in the public record for combining a credible witness, immediate physical trace evidence on multiple properties, contemporaneous official RAAF investigation, and a clean media trail. Tully gave its name to a generic UFO landing pattern — "saucer nest" — that would be applied to similar cases in subsequent decades.
