One of the UAP files which the Disclosure Australia Project (2003-2008) located in the National Archives of Australia (NAA), belonged to the Commonwealth Scientific and Industrial Research Organisation (CSIRO.) Click here to read about the CSIRO's role.
NAA file series A8520 control symbol HM1/30 was titled "CSIRO - General - UFOs." 90 pages, with a date range of 1957-1968 were made available to the Project at that time.
A recent look at the digital version of this file reveals that someone has paid to have additional pages made available in digital format. There are now 130 pages available for this file, dated up to 1981. However, the new documents are almost exclusively pieces of correspondence between individual members of the public and the CSIRO. The CSIRO's consistent response was that they did not research UAP and referred correspondents to the Department of Air, who held responsibility for investigating reports of UAP.
There are however, a couple of interesting items on the newly available pages:
1. A 20 foot diameter circle of 'scorched' grass was found in March 1969 at Kyogle, New South Wales. A toadstool from within the circle was examined by the Botanic gardens who suggested the ring might be of fungal origin. For further details click here.
2. A CSIRO employee privately examined a photograph taken in October 1972 at Lake Hume and pronounced it a double exposure.
