Beaumont Children

On Australia Day, January 26, 1966, siblings Jane (9), Arnna (7), and Grant Beaumont (4) left their home in the Adelaide suburb of Somerton Park to catch a bus to Glenelg Beach, a popular seaside destination about five minutes away. Their mother Nancy expected them home by noon on the 12:15 bus, but they never returned. It was a trip the children had made before without incident.

Witnesses at the beach reported seeing the three children playing with a tall, thin, blond-haired man in his mid-thirties. The children appeared comfortable with him, and some witnesses said the man had been seen with them on previous occasions. The children were last seen leaving the beach around noon with this man. When they failed to return home, their father Jim drove to the beach to search but found no trace of them.

The investigation that followed was the largest in Australian history at that time. Thousands of people were interviewed, hundreds of leads were pursued, and the case attracted international attention. Several suspects were investigated over the decades, most notably convicted child killer Bevan Spencer von Einem, whose crimes in the 1970s and 1980s bore similarities to the Beaumont case. Despite multiple excavations of suspected burial sites—including a factory site in 2018—no remains have ever been found.

The disappearance fundamentally changed Australian culture, ending an era of relative innocence in which children were routinely allowed to travel unsupervised. The case prompted significant changes to child safety awareness across the country. Jim Beaumont died in 2019, and Nancy Beaumont continues to live in Adelaide, still hoping for answers more than half a century later.
