as far as I know (last one I went to was 10 years ago) its not a card show, rather a collectables fair...so its got all sorts of shit, in a tiny old town hall, everything crammed in....
when I was going in the middle of the hobby boom, there was maybe 6 or 7 stalls...id really doubt there was that many?
On a trivial note, I work in Parramatta!
