I've found toy/comic fairs in Australia (Well, South Australia anyway, can't speak for other states..) a bit rubbish if you're looking for transformers, or anything really that's not Star wars, Funko pops, and diecast vehicles. Went to the Adelaide toy fair last weekend, there was one guy who must have bought up all the local stock of g1-box style headmasters and trying to sell them for $50ea, and a couple of people had some loose, no accessory and usually broken G1s for $50+. Not worth the time or entry cost if you aren't into the other mentioned stuff really.
