Aussie summer will kill you. Boiling cultural pots like Amsterdam are good fun. In summer you meet all sorts there - Americans, Naijas, Indians, Arabs, Chinese, name it. 24^7 lifestyle. Not sure coronavirus will allow this year. The rest of Europe like Marseilles French town can be a dead bore.
Europe and most of the west - Japs, Koreans - are only livened or cheered up by migrants and tourists. Deadbeat, politically sanitized automatons.
