Although the Australian release date is meant to be synchronised with Europe as Rocktober 16th, various places are reporting that if you walk into certain Australian chains you can pick it up right now.
Apparently EB Games decided to jump the gun, and keen to to not be outdone JB Hi-Fi followed suit shortly afterwards. Naturally this could result in a chain reaction (Ho ho!), so it’s probably worth checking other shops too.
If anyone knows of any other places that’ve broken the street date in Australia and beyond, do comment!
