I have just got off FaceTime with my mother in Australia, launch day there is tomorrow (19th). Not a single store (Vodafone, Telstra or Virgin) in the shopping mall she works at has the 6 plus in stock - they say it is at least a 3 week wait as Apple never sent them any of the larger models, only the iPhone 6. They were very dubious to start with just trying to get her to sign up and they would see if they could allocate her a 6+ tomorrow - they then admitted they never had any. Wonder if there is going to be a huge wait for NZ telcos to actually get them in. Apple US has them all on a 3-4 week back order.
Just got off the sales team. Phone will be available tomorrow(Pre-Order) on/off contract as they have told me. Looking forward to the iPhone 6+! No word yet on whether dummy units will be available. Hoping they are.
