The Big W's and Kmart's I've been in lately seem devoid of TFs aside from Big W's recent stock of Construct Bots. They seemed to cut back months ago. The Target and TRU I was recently in seemed well stocked.
Also, normally the date on the box is the same here in Australia as it is in the US. I've only seen one toy with stickers on it with a local date as opposed to a global dates printed on the box.
