A bright and bustling Australia Day, January 26, 1966, three young siblings—Jane (9), Arnna (7), and Grant (4) Beaumont—vanished from Glenelg Beach, a popular seaside destination near Adelaide. Despite a huge search and global media attention, the Beaumont children were never found, and the case remains one of Australia's most infamous and heartbreaking mysteries. Decades later, it still stirs intense curiosity and sorrow.

The Day They Disappeared

That morning, the Beaumont children boarded a bus from their Somerton Park home to Glenelg Beach, just a short 5-minute ride away. It was a trip they had taken many times before. They were spotted at several locations throughout the day: playing at the Colley Reserve, buying snacks at Wenzel’s cake shop, and even sharing a meat pie. Witnesses saw them with a tall, blonde man, described as being in his mid-thirties. The children appeared relaxed and familiar with him.

They were supposed to return by noon, but never boarded the bus back. By late afternoon, panic set in. Their mother, Nancy, waited anxiously at the bus stop. Their father, Jim, came home early from work and launched a desperate search. But the children were gone—without a trace.

🔍 The Investigation & Theories

Witness Reports:

Numerous people claimed they had seen the children in the company of a man who seemed to be gaining their trust. He was sun-tanned, lean, and appeared comfortable around them. One witness even said Jane, the eldest, was seen holding a banknote, odd because their mother had only given them coins.

A Nation Gripped:

The case exploded in the media. It was the first time Australia had experienced a disappearance of this scale involving multiple children. Police launched the largest search in the nation’s history. Beaches were combed, rivers dredged, houses searched. But not a single piece of hard evidence surfaced.

Harry Phipps & Renewed Digs:

Years later, suspicions turned toward a wealthy factory owner named Harry Phipps. He lived near the beach and allegedly resembled the composite sketch. In 2013 and again in 2023, investigators dug on his former property after two men—who were boys at the time—claimed they had been asked to dig a hole there by Phipps around the time of the disappearance. Despite the efforts, nothing conclusive was found.
