There’s a painting of Uluru in the art room. Part of Sydney is also illustrated by way of a famous street. This is a well known foreshadowing by GF. Or, it could be to put us off the scent of the real gen 10. Either way my money is on Australia.
That’s total rubbish, I’m afraid. Even the culture is vastly different. The links between Britain and Australia have been pretty different for decades.
Geographically Australia could be the most intense Pokemon experience by way of its outback, tropical areas, beaches, cities and more.
If GF can make sure they include appropriate references to colonising and how bad it is, and make sure the Aborigines are represented in the best way, then I’d be all for it. My biggest criticism of Unova (as nods to the United States) was not representing the Native American people in a meaningful way in its development.
