The Disclosure Australia website at http://disclosureaustralia.freewebpages.org has recently posted the final version of its research findings from its five year search through the UFO files of the Australian Government. Go to the website; look under "What's new?" for "UAS files located in the Australian Government record system" Part 1 and Part 2.
There is also a listing of the 150+ files which the Project uncovered. Then, because the Project had the National Archives of Australia make many of the files available electronically, you can read thousands of pages from the files for yourself at http://www.naa.gov.au Go to this website, click on "RecordSearch" , then click on "search as a guest", then in the box titled "keywords", type in the words "flying objects" and open any file which says there is a digital copy available.
It is amazing just what the Disclosure Australia team found out and we all owe them a great debt of gratitude for all this work.
