I went to Boronia today to check out ToyZone, worth the 2 hour train trip. Manage to get their hours. They're open Tuesday to Saturday from 10am, my mind kind of slip here, so to be on the safe side, I'll say until 5 Tuesday to Friday and 4 on Saturday. Managed to pick up Steamhammer and Blast-Off (from K-mart)
I had a chat with the owners and they say they can special order stuff by request and they're setting up a website that will ship items out.
