BIO: Bill Chalker Intrigued by UFO reports since about 1966, when his home town of Grafton, in New South Wales (NSW), Australia, became the focus of UFO activity that attracted national headlines, Bill began undertaking deeper research and investigations from 1969, when his home region of northern NSW again became the focus of UFO reports. The 1969 publication of the notorious Condon Report, which concluded that there was nothing of scientific value in studying UFOs, had a different effect on Bill. Unlike most, he examined the massive report and realised there was a massive disconnection between the conclusions and the actual case studies. More than a third of their cases were unexplained. This set Bill on a deeper investigation of the UFO enigma. He joined the American based APRO (Aerial Phenomena Research Organisation) group, which confirmed his growing awareness of the global dimensions of the UFO mystery.
He would eventually become their Australian representative. He also joined the US MUFON organisation, serving as their NSW representative for a number of years. Bill also joined the Sydney based UFO Investigation Centre (UFOIC) as a country member and investigator. Between 1971 and 1974 while studying at the University of New England (NSW), Bill undertook investigations in significant localised UFO flap areas, such as Kempsey, Tyringham on the Dorrigo plateau, Mount Butler near Armidale and the northern rivers area of NSW. He became a co-ordinator of UFOIC soon after moving to Sydney in 1975. He helped transition UFOIC to a low profile networking group, to better enable in depth research and investigations, and continues coordinating UFOIC activity and compiling the group history and drawing together case data and material gathered over more than 6 decades. Trained in science with a university honours degree majoring in Chemistry and mathematics Bill has had decades of experience in chemistry, laboratory management and quality assurance. That extensive background is reflected in the strong focus he brings to particular areas of UFO research interest, which include physical evidence (such as UFO landing “physical traces” and biological evidence/DNA related investigations), historical UFO events (pre-1947), and official investigations. Bill’s research has been extensively published in such diverse publications as FSR (Flying Saucer Review – his first FSR piece appearing in 1973), the MUFON UFO Journal, the APRO Bulletin, IUR (International UFO Reporter), ACOS Bulletin, ACUFOS Journal, UFORAN (UFO Research Australia Newsletter) magazine, the Australasian Ufologist, Hard Evidence, Fate, Reader’s Digest, Omega Science Digest, Independent Monthly, Rolling Stone, Australian Penthouse, Fortean Times, and New Dawn. Bill was a contributing editor to the Chicago based IUR, the publication of Allen Hynek’s Center for UFO Studies. Bill has written long running columns in the Ufologist magazine (“UFO History Keys” (2006 to 2011) which examine the UFO subject from a historical perspective, and “Science and the UFO controversy” (from 2011 to 2018)) and the UK e-magazine “UFO Truth” (“The OZ Files” from 2013 to now ongoing). Some of Bill’s contributions include: A focus of UFO landing “physical trace cases” – see for example his chapter “Physical Traces” in the 1988 book “UFOs 1947 1947-1987 – the 40-year search for an explanation”. Examination of early pre-1947 cases, including two striking cases – 1868 (a contact case from Parramatta, NSW) and a bizarre “mothman” style UFO milieu in 1927 (at Fernvale, NSW) – see for example on the web Bill’s document: Early Australian Historical Encounters and his 2018 UFO Encyclopedia contributions: “Airship Sightings in New Zealand/Australia” and “Fernvale Episode.” Research into official investigations in Australia. During 1982 to 1984 he undertook a comprehensive review of official files at the Australian Department of Defence in Canberra, providing at that time an unprecedented level of “disclosure” of official files to the wider UFO research and public community. See for example Bill’s “UFO Sub Rosa Down Under” document on the web since 1999 and “The Australian Military and the Official Government Response” chapter in the 2012 book “UFOs and Government.” Focus on alien abduction research since the 1970s, undertaking research with psychologists during the 1980s, contributing to researching and documenting many such cases, and focused since 1999 on the biochemical DNA dimensions of this controversial area, particularly with his breakthrough research on the controversial “alien hair” from Peter Khoury’s abduction experiences in Sydney Australia. This research has led to a focus of “the alien DNA paradigm” – an extraordinary opportunity to get to the heart of the alien abduction mystery. Bill has also focused on the Asian UFO experience, in particular, the fascinating Chinese UFO scene, as an effective way of validating the global reality of the UFO experience. Bill has been to China 3 times since 2002, creating excellent research ties with Chinese UFO researchers and lecturing there at the Dalian UFO conference in 2005 and at universities in Kunming and Beijing in 2006. During 2006 he was able to research UFO and mystery light phenomena in Thailand, particularly focusing on the fascinating Naga light festival near Nong Khai where strange lights come out of the Mekong River. During October 2006 he was able to capture the phenomenon on video. Bill has maintained a long time focus on so-called UFO “solid light” cases. See for example his article “UFOs & the solid Light Enigma”, New Dawn Special Issue Vol 13 No 1 (2019). Bill has had two commercial books published – “The OZ Files – the Australian UFO story” by Duffy & Snellgrove Sydney Australia in 1996 and “Hair of the Alien – DNA and other forensic Evidence of Alien Abduction” by Paraview Pocket Books, a division of Simon & Schuster, New York, USA in 2005. He was the Australian chapter author of the UFO History Group’s major study “UFOs and Government” (2012) and Australian content author for all 3 editions (a total of 7 volumes from 1990 to 2018) of Jerome Clark’s “The UFO Encyclopedia” – the latest in 2 volumes (2018) and in a 7-part series (2021). Since 2005 he has maintained a blog – “The OZ Files” – covering research, investigation and commentary on the UFO/UAP subject, and includes links to his other blogs addressing historical (pre-1947) UFO reports in Australia, science & the UFO controversy, the “alien DNA paradigm”, UFOIC history & activities and broader UFO historical focuses, and links to many of Bill’s article and documents via AUFORN and Project 1947.
