Unfortunately it looks like I'll have to skip collecting exclusives and just buy direct from HK for new releases, where registered air parcel charges are usually in the $30 to 40US range for 1/6 scale, and at times the figures can also be bought under Sideshow's retail.
That's what I do; Studio Sunny is bomb! I think all Australians should do it that way. In some cases even where the total price would be the same as SS (ie. higher item price, lower shipping), you still get the figure a month earlier than if you were to order from SS. I sometimes think I would feel more secure if I PO'd half the stuff from SS, Toys2 etc., but it seems like there is more than enough stock on eBay come the release in HK. (On a side note: was about to click 'Buy It Now' on John Connor last week, then saw the recall on the headsculpts! Phew! Dodged that bullet!)
