Fair costs $6 entrance fee. Arrive early as loopy has said - he attended once when he was playing tourist in NSW. Fair opens 8am (on a Sunday , ugh, I know) come and introduce yourself, you'll easily spot other OTCA members anyways (TF clothing galore a dead giveaway)were usually at the head of the line chatting like seagulls. Once inside there's usually 2 staple seller - Jaime and Skyshadow... then some more scattered everywhere ( its not a big hall anyhow). youd usually be rubbing elbows (literally) with your fellow OTCA members in looking and buying at these stalls so if your quite unsure about something ( if a figure is legit, or what the heck is this figure?) just ask away, someones bound to have the answers and answer back while scrounging among the display piles ( at times dont expect eye contact while the feeding frenzy is happening,, but you'll get an answer). Oh and dont worry its just like a flea market atmosphere with 80s toon themes in the background playing and dont forget to go to the side hall, theres some more sellers there with stuff you might find interesting. After an hour or two you'll notice most of the OTCA members discreetly slinkering out - its time for the usual after fair toys show and tell over lunch, then go around Parramata shopping center to look for anything new and interesting (this includes comic shops) to buy.... so thats how it goes in a nutshell. By 1 pm or so members have gone home or some go with others still to look around back at the hall (it runs til 3pm and some items gets discounted prices at the end).
