Jack Sim

Jack Sim walks between worlds as Brisbane's infamous "man in black," a keeper of forgotten memories and collector of shadow stories. His soul purpose revealed itself in childhood through an otherworldly attraction - not to earthly playthings - but to the whispers of the past. He was drawn to tales of crime, spirit encounters, and the lost souls who dwelt behind prison walls. As a prolific chronicler of the unseen, Jack has manifested multiple grimoires of hidden knowledge through three book series (Murder Trails, Ghost Trails, and Boggo Road Gaol), and his role as a spiritual way-shower manifests through his nocturnal pilgrimages—leading seekers through haunted portals like Boggo Road Gaol and the ancient grounds of Toowong Cemetery. Jack has touched many souls through various media channels, including his 4BC radio appearances where he discusses and debates true crime stories and the mysteries of the paranormal world, alongside fellow truth-seekers from UFO Research Queensland.
