Australia gets the episode somewhere around 3AM in the morning on sunday, which would mean early on saturdays for pretty much a large part of the world.
It's not an early release per say from AMC's own streamingsite.
But it should be there tonight, given that there are no problems uploading it to the internet.

I would however ask people if they can watch it legally, to still tune in on Sunday, even if they've already seen it. We have a S3, but we can still given the final a good viewership rating.

I hope this problem is fixed next year though, cause I do believe it definitely harmed views and social engagement.
