If you have a 6 Pro, why would you need to buy a replacement after only a year?
If they sold the 512 7 Pro in Europe I might buy it and offer the 6 Pro to my mother-in-law who has a 5 or so year-old phone now (or my mother with her 4-year-old one, or maybe to my wife, and she in turn to her mother), but I don't think I will be going through the Australian workaround and the associated customs and warranty risks for that.
