I went and checked this out: http://www.dcita.gov.au/cgp/musiclitpages/musiclit14.html
.... a couple of days ago since I live nearby. There was a couple of minor Queen items in the colletion including invoces for transport of equipment, a couple of small newspaper articles detailing how members of the visiting party were STRIP SEARCHED at the airport and there is supposedly a signed photo of the guys which may have been put aside. No video unfortunately.
Also, I'm still seeking video footage of the QPR show in Seattle '06 if anyone can assist (even from mobile phones an digital cameras would be great)
