Down here in Victoria both council run and privately owned sites are around and I've mentioned them before on the forum without declaring their specific locations, I have way too much stuff as it is and am running short on space so the new rule is nothing comes in unless something goes out, no exceptions. I occasionally might pay a visit to the local sites but only if there is something that I am specifically after such as a cabinet for a power supply or another UPS which are always readily available.
It's a lucky dip as to what you might find and it changes daily, for instance a couple of months back there was a massive load of Lockwood/ Abloy door and window locks along with a huge amount of associated hardware including key blanks available, all new stock and in boxes indicating that a locksmith shop had possibly closed and the remaining stock given to the local council depot. Another time I picked up about $1800 worth of patch panels and hundreds of 3M Cat5 and Cat6 RJ45 sockets all new in packets for $70 for the whole lot, I already had plenty but couldn't leave them there at that price.
