Bill Chalker

Bill Chalker is an Australian UFO researcher, author, and chemist based in Sydney. With degrees in chemistry and mathematics from the University of New England, he began investigating UFOs in the early 1970s, inspired by the Condon Report's disconnect from unexplained cases. He served as Australian representative for APRO (1978-1986), NSW representative for MUFON (1976-1993), and coordinator of UFOIC since 1975. Key achievements include physical evidence analysis, pre-1947 events, and government file access. Notable books: 'The OZ Files' (1996) and 'Hair of the Alien' (2005). He contributed to International UFO Reporter, Flying Saucer Review, and New Dawn magazine, and is quoted as an expert in media.
