It actually looks like Popcultcha has hidden Han from Australians. If you set your currency as USD, Han is available to purchase. Change it back to AUD he's not on the list. But you can manually search him.
Personally I haven't bought much from PC sales since they stopped allowing the discount on preorders (they did require you to pay in full at the time to get it). All the good stuff is usually picked clean before the sale starts these days. I also used to like being up at midnight when the new deal would tick over waiting to secure that great item. Unfortunately our dollar is unlikely to change so this is likely the new norm. Congrats to all who find something though.
