I went to the one in Sydney earlier on in the year.
The doors were just opening and there were quite a few people lined up already (maybe around 20-30). When i got inside alot of people were still setting up, but there was a good mix of gear on offer.
From my observations SLR bodies/lenses were essentially at "ebay prices", but i noticed quite a few rangfinders, and other gear like cases, filters etc that were going pretty quickly at cheap prices. I was lucky to pick up a couple things that i thought were very cheap.
Afterwards I heard that people were giving away old film developing gear near the end of the day, but it was more trash than treasure.
I'm going to try and make it to the one coming up in October eventhough i probably shouldnt!
