Allen Tiller is an award-winning historian, genealogist, author, and researcher from South Australia, specialising in historical true crime, paranormal history, and folklore. Widely regarded as one of Australia's most respected and experienced paranormal historians, Allen combines rigorous academic research with engaging storytelling to bring the past to life for contemporary audiences.

Allen was recently commissioned by South Australian government departments to research the haunted histories of Adelaide, Port Adelaide, and Salisbury. His work resulted in the development of four historically based ghost and heritage tours that use true crime, folklore, and paranormal narratives to engage audiences who might not otherwise connect with local history.

While Allen is widely recognised as a paranormal investigator and "ghost hunter," his primary expertise lies in historical and genealogical research. He holds a Bachelor of Arts (First Class Honours) in History and a Diploma of Family History from the University of Tasmania, along with qualifications in Library and Information Services from TAFE SA.

Allen gained international recognition through his appearance on the television series Haunting: Australia and has featured on numerous Australian television programs, including Today Tonight, A Current Affair, SA Life, and Studio 10. A sought-after commentator, he has also appeared extensively across radio, print, and digital media, with interviews on ABC Radio, Nova, Triple M Limestone Coast, and various international outlets.

His distinctive combination of historical scholarship and paranormal investigation has established him as a leading voice in paranormal history, theory, and investigative methodology. Allen is also a published author and the only Australian paranormal investigator to have two research projects preserved within the National Library of Australia's Pandora Archive, recognising the significance of his contributions to both historical and paranormal research.

To date, Allen has authored ten publications, including The Haunts of Adelaide: History, Mystery, and the Paranormal; Haunted Kapunda; Haunted Adelaide; Haunted Playford; Haunted Salisbury; The Pirate Bushrangers; A History of the North Kapunda Hotel; A History of the Kapunda Congregational Church; Haunted Adelaide Plains; and Shades of Black.

Beyond his professional work, Allen has made significant contributions to community service and heritage preservation. His volunteer roles have included service with the Mallala Museum, the Adelaide Plains Historical Committee, the Gawler History Team (Vice-President), the Gawler Cultural Heritage Collection Committee, and community organisations such as Humbug Scrub Wildlife Sanctuary, the Crippled Children's Association, White Ribbon, and the Kapunda Men's Shed.

Through his research, writing, public speaking, media appearances, and heritage tours, Allen continues to make history accessible, engaging, and relevant, inspiring audiences to explore the stories, people, and mysteries that have shaped Australia's past.
