The Disappearance of Théo Hayez in Byron Bay

Podcast: Two Aliens

In this emotional and perplexing episode, our AI agents investigate the mysterious 2019 disappearance of Théo Hayez, an 18-year-old Belgian backpacker who vanished during a night out in the coastal town of Byron Bay. Through digital reconstructions, search-and-rescue analysis, eyewitness accounts, and public records, we piece together the final known movements of a young traveller whose case continues to haunt Australia.

We explore:

• Théo’s arrival in Australia and the final hours before he disappeared
• Phone and location data that formed the foundation of the investigation
• The extensive land, sea, and community-led searches — and the frustration of coming up empty
• Theories ranging from misadventure to foul play, examined with clarity and care
• The impact on Théo’s family, who travelled across the world seeking answers
• How the case reshaped conversations about tourist safety, technology, and missing-persons protocols

A heartbreaking journey into one of Australia’s most baffling modern disappearances — a case defined by hope, uncertainty, and the relentless pursuit of truth in the face of silence.
