I should have read your earlier post (or at least used command-F)Kaiser Wilhelm III said:New Zealand is part of Australia in this TL, joining with them in *Federation in 1882. This was proposed OTL, and was widely assumed to be likely, although for various reasons they didn't end up joining. (Mostly to do with not enough perceived economic benefits and that it wouldn't strengthen Imperial unity). In this TL, with greater economic union between them earlier, they joined. And, in time, will have a truly stunning combined rugby team.
