The NFSA regularly features on ABC local radio in Canberra. It is truly a national treasure. It's worth looking at its web site. I see from the link above that their screening of Starstruck last week cost $5. Five Bucks!! The Archive is a government instrumentality, so it may not go down the commercial path of releasing the film on blue ray or similar media. Perhaps it should.
For those of you thinking of visiting Canberra, it is one of a number of 'national institutions' that are seriously impressive and open to the public. The National Gallery of Australia, the National Portrait Gallery, the National Library, the National Museum of Australia, the Australian War Memorial and MAD (the Museum of Australian Democracy in the old Parliament House).
