keep records of "sighting" and associated phenomena reported within Australian and associated territories." By 1969, Phenomena Research Australia (PRA) changed their policy and opened limited membership to the general public with a new newsletter called UFO And Phenomena. 1970s In late 1970, Tasmania UFO Investigation Centre (TUFOIC) produced the Tasmanian UFO Report, later TUFOIC Newsletter, a magazine that covered 86 issues (1970 to 1999). On 30 October 1971, a symposium was held in Adelaide. The symposium, on UFOs, was organised by the SA Division of the Australian and New Zealand Association for the Advancement of Science. Victorian groups VUFORS and PRA invited Dr. J. Allen Hynek to visit Australia. He accepted the invitation and in 1973 arrived in Australia, spending four days in Melbourne, followed by short stops in Sydney, ACT, Brisbane and Papua New Guinea. While in Victoria, Dr. Hynek also met with Rev. William Gill, who was involved in the famous "close encounters of the third kind" case that occurred in the Anglican mission village at Boianai, Papua, New Guinea,. He also journeyed to Papua, which enabled him to undertake a detailed on site investigation into this famous case. Victorian members of VUFORS and PRA arranged that, during his stay in the ACT, he was able to talk with Shamus O'Farrell, discussing O'Farrell's famous 1954 Sea Fury incident. In 1974, Harry Griesberg and David Seargent established the Australian Co-ordination Section (ACOS) of the US-based Center for UFO Studies (CUFOS). This followed the 1973 visit to Australia of Dr J. Allen Hynek, who requested that Australian ufologists forward copies of interesting Australian sighting reports to CUFOS in the US. In 1978, VUFORS changed direction following the resignation of Peter Norris. A new executive was placed in control, ensuring the continuing prosperity of VUFORS. By 1978 VUFORS had the largest membership of any UFO organisation in the Southern Hemisphere. Defence UFO files open Although the UFO files were available to Defence personnel and Civilians Defence personnel for years, these files remained closed to outside researchers. In October 1979, extensively through the efforts of VUFORS researchers and Fl/Lt Brett Biddington (later Group Captain – RAAF), the RAAF invited Victorian researchers to visit the Intelligence Cell at RAAF Headquarters Support Command, Victoria Barracks, Victoria, to view the majority files collection and copy what they wished. This was a significant 'turn around' by the Defence Force, but it was the start of a
