I'm sure the IFIXIT teardown team is on the ground in Australia as we speak sharpening their knifes and prepping the camera stand, just up the street from the Melbourne Apple Store where someone is standing inline as the fourth person to get into the store when the doors open any monument now (its Friday their first).
Not that I really know for sure... ;-}
Really, don't worry I'm sure the IFIXIT team will be doing a through teardown in do course. One does need to wait until the product is even available first.
Well Here you go: iPhone 6 Teardown
